Fossil

Changes for version 2.17 (pending)

• Added new options to the various diff commands: --by, -b, --webpage, --json, --tcl.
• Performance and display improvements to the internal diff engine, including partial-line matching for unified diffs and improved partial line matching for side-by-side diffs.
• The --branchcolor option on fossil commit and fossil amend can now take the value "auto" to force Fossil to use its built-in automatic color choosing algorithm.
• Fossil now autosyncs prior to running fossil open.
• Add the ticket-default-report setting, which if set to the title of a ticket report causes that ticket report to be displayed below the search box in the /ticket page.
• The "nc" query parameter to the /timeline page causes all graph coloring to be omitted.
• Improvements and bug fixes to the new "fossil ui REMOTE" feature so that it works better on a wider variety of platforms.
• In /wikiedit, show the list of attachments for the current page and list URLs suitable for pasting them into the page.
• Add the --no-http-compression option to fossil sync and similar.
• Print total payload bytes on a fossil sync when using the --verbose option.
• Add the close, reopen, hide, and unhide subcommands to the branch command.
• The Markdown formatter now interprets the content of block HTML markup (such as <table>) in most cases. Only content of <pre> and <script> is passed through verbatim.
• The wiki list command no longer lists "deleted" pages by default. Use the new --all option to include deleted pages in the output.

Changes for Version 2.16 (2021-07-02)

• Security: Fix the client-side TLS so that it verifies that the server hostname matches its certificate.
• The default "ssh" command on Windows is changed to "ssh" instead of the legacy "plink", as ssh is now generally available on Windows systems. Installations that still need to use the legacy "plink" can make that happen by running: 'fossil set ssh-command "plink -ssh" --global'.
• Added the fossil patch command.
• The fossil ui command is enhanced in multiple ways:
  1. The REPOSITORY argument can be the name of a check-out directory.
  2. If the REPOSITORY argument is prefixed by "HOST:" or "USER@HOST:" then the ui is run on the remote machine and tunnelled back to the local machine using ssh. (The latest version of fossil must be installed on both the local and the remote for this to work correctly.)
  3. The new --nobrowser and --fossilcmd options is provided.
• The /brlist web page allows the user to select multiple branches to be displayed together in a single timeline.
• The Forum provides a hyperlink on the author of each post that goes to a timeline of recent posts by that same author.
• Added the "fossil bisect run" command for improved automation of bisects.
• The fossil merge command now does a better job merging branches where files have been renamed between the current branch and the branch being merged.
• The fossil open command allows the repository file to be inside the working directory without requiring the --force flag.
• The /wikiedit and /wikinew pages now default to markdown format.
• The /login page now links to a user's forum post timeline if the repository has forum posts.
• Tags may now be propagated for forum posts, wiki pages, and technotes. The tag command can now manipulate and list such tags.
• Login-Groups are now shown on the repository list of the "fossil all ui" command.
• Administrators can configure email alerts to expire a specific number of days (ex: 365) after the last user contact with the Fossil server. This prevents alert emails being sent to abandoned email accounts forever.
• SQL that defines database objects for tickets now can DROP a VIEW or an INDEX provided that its name starts with 'ticket' or 'fx_'.
• Update the built-in SQLite to version 3.36.0.
• Numerous other minor enhancements.

Changes for Version 2.15 (2021-03-26) and Patch 2.15.1 on (2021-04-07) and 2.15.2 on (2021-06-15)

• Patch 2.15.2: Fix the client-side TLS so that it verifies that the server hostname matches its certificate. Upgrading to the patch is recommended.
• Patch 2.15.1: Fix a data exfiltration bug in the server. Upgrading to the patch is recommended.
• The default CSP has been relaxed slightly to allow images to be loaded from any URL. All other resources are still locked down by default.
• The built-in skins all use the "mainmenu" setting to determine the content of the main menu. The ability to edit the "mainmenu" setting is added on the /Admin/Configuration page.
• The hamburger menu is now available on most of the built-in skins.
• Any built-in skin named "X" can be used instead of the standard repository skin by adding the URL parameter skin=X to the request. The selection is persisted using the display preferences cookie unless the "once" query parameter is also included. The /skins page may be used to select a skin.
• The /cookies page now gives the user an opportunity to delete individual cookies. And the /cookies page is linked from the /sitemap, so that it appears in hamburger menus.
• The /sitemap extensions are now specified by a single new "sitemap-extra setting", rather than a cluster of various "sitemap-*" settings. The older settings are no longer used. This change might require minor server configuration adjustments on servers that use /sitemap extensions. The /Admin/Configuration page provides the ability to edit the new "sitemap-extra" setting.
• Added the "--ckout-alias NAME" option to fossil ui, fossil server, and fossil http. This option causes Fossil to understand URIs of the form "/doc/NAME/..." as if they were "/doc/ckout/...", to facilitate testing of embedded documentation changes prior to check-in.
• For diff web pages, if the diff type (unified versus side-by-side) is not specified by a query parameter, and if the "preferred-diff-type" setting is omitted or less than 1, then select the diff type based on a guess of whether or not the request is coming from a mobile device. Mobile gets unified and desktop gets side-by-side.
• The various pages which show diffs now have toggles to show/hide individual diffs.
• Add the "preferred-diff-type" setting to allow an admin to force a default diff type.
• The "pikchr-background" settings is now available in "detail.txt" skin files, for better control of Pikchr colors in inverted color schemes.
• Add the --list option to the tarball, zip, and sqlar commands.
• The javascript used to implement the hamburger menu on the default built-in skin has been made generic so that it is usable by a variety of skins, and promoted to an ordinary built-in javascript file.
• New TH1 commands: "builtin_request_js", "capexpr", "foreach", "lappend", and "string match"
• The leaves command now shows the branch point of each leaf.
• The fossil add command refuses to add files whose names are reserved by Windows (ex: "aux") unless the --allow-reserved option is included. This helps prevent unix users from accidentally creating check-ins that are unreadable by Windows users.
• Add the "re=" query parameter to the /dir webpage, for symetry with the /tree page.
• Update the built-in SQLite to version 3.35.0.
• The ./configure script now has the --print-minimum-sqlite-version option that prints the minimum SQLite version required by the current version of Fossil. This might be used by integrators who insist on building Fossil to link against the system SQLite library rather than the built-in copy of SQLite, to verify that their system SQLite library is recent enough.
• Webpage that shows history of a wiki page gained client-side UI to help with comparison between two arbitrary versions of a wiki (by the means of anchoring a "baseline" version) and the ability to squeeze several sequential edits made by the same user into a single "recycled" row (the latest edit in that sequence).

Changes for Version 2.14 (2021-01-20) and Patch 2.14.1 on (2021-04-07) and 2.14.2 on (2021-06-15)

• Patch 2.14.2: Fix the client-side TLS so that it verifies that the server hostname matches its certificate. Upgrading to the patch is recommended.<
• Patch 2.14.1: Fix a data exfiltration bug in the server. Upgrading to the patch is recommended.
• Schema Update Notice #1: This release drops a trigger from the database schema (replacing it with a TEMP trigger that is created as needed). This change happens automatically the first time you add content to a repository using Fossil 2.14 or later. No action is needed on your part. However, if you upgrade to version 2.14 and then later downgrade or otherwise use an earlier version of Fossil, the email notification mechanism may fail to send out notifications for some events, due to the missing trigger. If you want to permanently downgrade an installation, then you should run "fossil rebuild" after the downgrade to get email notifications working again. If you are not using email notification, then the schema change will not affect you in any way.
• Schema Update Notice #2: This release changes how the descriptions of wiki edits are stored in the EVENT table, for improved display on timelines. You must run "fossil rebuild" to take advantage of this enhancement. Everything will still work without "fossil rebuild", except you will get goofy descriptions of wiki updates in the timeline.
• Add support for Fossil chat.
• The "fossil clone" command is enhanced so that if the repository filename is omitted, an appropriate name is derived from the remote URL and the newly cloned repo is opened. This makes the clone command work more like Git, thus making it easier for people transitioning from Git.
• Added the --mainbranch option to the fossil git export command.
• Added the --format option to the "fossil timeline" command.
• Enhance the --numstat option on the "fossil diff" command so that it shows a total number of lines added and deleted and total number of files modified.
• Add the "contact" sub-command to fossil user.
• Added commands "fossil all git export" and "fossil all git status".
• Added the "df=CHECKIN" query parameter to the /timeline page.
• Improvements to the "/sitemap" page. Add subpages /sitemap-timeline and /sitemap-test.
• Better text position in cylinder objects of Pikchr diagrams.
• New "details.txt" settings available to custom skins to better control the rendering of Pikchr diagrams:
  • pikchr-foreground
  • pikchr-scale
  • pikchr-fontscale
• Allow the use of SQL functions inside the ticket table definition for custom ticket configurations.
• The built-in SQLite is updated to version 3.35.0 alpha containing performance optimizations, especially performance associated with startup, and minor improvements to the CLI.
• Performance optimizations to Fossil itself.
• Countless improvements and enhancements to the documentation

Changes for Version 2.13 (2020-11-01)

• Added support for interwiki links.
• Enable <del> and <ins> markup in wiki.
• Improvements to the Forum threading display.
• Added support for embedding pikchr markup in markdown and fossil-wiki content.
• The new "pikchr" command can render pikchr scripts, optionally pre-processed with TH1 blocks and variables exactly like site skins are.
• The new pikchrshow page provides an editor and previewer for pikchr markup.
• In /wikiedit and /fileedit, Ctrl-Enter can now be used initiate a preview and to toggle between the editor and preview tabs.
• The /artifact and /file views, when in line-number mode, now support interactive selection of a range of lines to hyperlink to.
• Enhance the /finfo webpage so that when query parameters identify both a filename and a checkin, the resulting graph tracks the identified file across renames.
• The built-in SQLite is updated to an alpha of version 3.34.0, and the minimum SQLite version is increased to 3.34.0 because the /finfo change in the previous bullet depends on enhancements to recursive common table expressions that are only available in SQLite 3.34.0 and later.
• Countless other minor refinements and documentation improvements.

Changes for Version 2.12.1 (2020-08-20)

• (2.12.1): Fix client-side vulnerabilities discovered by Max Justicz.
• Security fix in the "fossil git export" command. The same fix is also backported to version 2.10.1 and 2.11.1. New "safety-net" features were added to prevent similar problems in the future.
• Enhancements to the graph display for cases when there are many cherry-pick merges into a single check-in. Example
• Enhance the fossil open command with the new --workdir option and the ability to accept a URL as the repository name, causing the remote repository to be cloned automatically. Do not allow "fossil open" to open in a non-empty working directory unless the --keep option or the new --force option is used.
• Enhance the markdown formatter to more closely follow the CommonMark specification with regard to text highlighting. Underscores in the middle of identifiers (ex: fossil_printf()) no longer need to be escaped.
• The markdown-to-html translator can prevent unsafe HTML (for example: <script>) on user-contributed pages like forum and tickets and wiki. The admin can adjust this behavior using the safe-html setting on the Admin/Wiki page. The default is to disallow unsafe HTML everywhere. Example.
• Added the "collapse" and "expand" capability for long forum posts. Example
• The "fossil remote" command now has options for specifying multiple persistent remotes with symbolic names. Currently only one remote can be used at a time, but that might change in the future.
• Add the "Remember me?" checkbox on the login page. Use a session cookie for the login if it is not checked.
• Added the experimental "fossil hook" command for managing "hook scripts" that run before checkin or after a push.
• Enhance the fossil revert command so that it is able to revert all files beneath a directory.
• Add the fossil bisect skip command.
• Add the fossil backup command.
• Enhance fossil bisect ui so that it shows all unchecked check-ins in between the innermost "good" and "bad" check-ins.
• Added the --reset flag to the "fossil add", "fossil rm", and "fossil addremove" commands.
• Added the "--min N" and "--logfile FILENAME" flags to the backoffice command, as well as other enhancements to make the backoffice command a viable replacement for automatic backoffice. Other incremental backoffice improvements.
• Added the /fileedit page, which allows editing of text files online. Requires explicit activation by a setup user.
• Translate built-in help text into HTML for display on web pages. Example.
• On the /timeline webpage, the combination of query parameters "p=CHECKIN" and "bt=ANCESTOR" draws all ancestors of CHECKIN going back to ANCESTOR. For example, /timeline?p=202006271506&bt=version-2.11 shows all ancestors of the checkin that occured on 2020-06-27 15:06 going back to the 2.11 release.
• Update the built-in SQLite so that the "fossil sql" command supports new output modes ".mode box" and ".mode json".
• Add the "obscure()" SQL function to the "fossil sql" command.
• Added virtual tables "helptext" and "builtin" to the "fossil sql" command, providing access to the dispatch table including all help text, and the builtin data files, respectively.
• Delta compression is now applied to forum edits.
• The wiki editor has been modernized and is now Ajax-based. The WYSIWYG editing option for Fossil-format wiki pages was removed. (Please let us know, via the site's Forum menu, if that removal unduly impacts you.) This also changes the semantics of the wiki "Sandbox": that pseudo-page may be freely edited but no longer saved via the UI (the wiki CLI command can, though).
• The allow-symlinks setting no longer syncs. It must be activated individually on any clones which require symlinks.
• Countless documentation enhancements.

Changes for Version 2.11 (2020-05-25)

• (2.11.2): Backport security fixes from 2.12.1
• (2.11.1): Backport security fix for the "fossil git export" command.
• Support Markdown in the default ticket configuration.
• Timestamp strings in object names can now omit punctation. So, for example, "202004181942" and "2020-04-18 19:42" mean the same thing.
• Enhance backlink processing so that it works with Markdown-formatted tickets and so that it works for wiki pages. Ticket [a3572c6a5b47cd5a].
  • "fossil rebuild" is needed to take full advantage of this fix. Fossil will continue to work without the rebuild, but the new backlinks will be missing.
• The algorithm for finding the location of the configuration database is enhanced to be XDG-compliant.
• Add a hide/show feature to associated wiki display on check-in and branch information pages.
• Enhance the "fossil info" command so that it works with no arguments even if not within an open check-out.
• Many improvements to the forum and especially email notification of forum posts, in response to community feedback after switching SQLite support from a mailing list over to the forum.
• Minimum length of a self-registered user ID increased from 3 to 6 characters.
• When the "vfx" query parameter is used on the "/timeline" page, it causes the complete text of forum posts to be displayed.
• Rework the "fossil grep" command to be more useful.
• Expose the redirect-to-https setting to the settings command.
• Improve support for CGI on IIS web servers.
• The /ext page can now render index files, in the same way as the embedded docs.
• Most commands now support the Unix-conventional "--" flag to treat all following arguments as filenames instead of flags.
• Added the mimetypes config setting (versionable) to enable mimetype overrides and custom definitions.
• Add an option on the /Admin/Timeline setup page to set a default timeline style other than "Modern".
• In embedded documentation, hyperlink URLs of the form "/doc/$CURRENT/..." the "$CURRENT" text is translated into the check-in hash for the document currently being viewed.
• Added the /phantoms webpage that shows all phantom artifacts.
• Enhancements to phantom processing to try to reduce bandwidth-using chatter about phantoms on the sync protocol.
• Security: Fossil now assumes that the schema of every database it opens has been tampered with by an adversary and takes extra precautions to ensure that such tampering is harmless.
• Security: Fossil now puts the Content-Security-Policy in the HTTP reply header, in addition to also leaving it in the HTML <head> section, so that it is always available, even if a custom skin overrides the HTML <head> and omits the CSP in the process.
• Output of the fossil diff -y command automatically adjusts according to the terminal width.
• The Content-Security-Policy is now set using the default-csp setting.
• Merge conflicts caused via the merge and update commands no longer leave temporary files behind unless the new --keep-merge-files flag is used.
• The /artifact_stats page is now accessible to all users if the new "artifact_stats_enable" setting is turned on. There is a new checkbox under the /Admin/Access menu to turn that capability on and off.
• Add the fossil tls-config command for viewing the TLS configuration and the list of SSL Cert exceptions.
• Captchas all include a button to read the captcha using an audio file, so that they can be completed by the visually impaired.
• Stop using the IP address as part of the login cookie.
• Bug fix: fix the SSL cert validation logic so that if an exception is allowed for particular site, the exception expires as soon as the cert changes values.
• Bug fix: the FTS search into for forum posts is now kept up-to-date correctly.
• Bug fix: the "fossil git export" command is now working on Windows
• Bug fix: display Technote items on the timeline correctly
• Bug fix: fix the capability summary matrix of the Security Audit page so that it does not add "anonymous" capabilities to the "nobody" user.
• Update internal Unicode character tables, used in regular expression handling, from version 12.1 to 13.
• Many documentation enhancements.
• Many minor enhancements to existing features.

Changes for Version 2.10 (2019-10-04)

• (2.10.2): backport security fixes from 2.12.1
• (2.10.1): backport security fix for the "fossil git export" command.
• Added support for CGI-based Server Extensions.
• Added the repolist-skin setting used to add style to repository list pages.
• Enhance the hierarchical display of Forum threads to do less indentation and to provide links back to the previous message in the thread. Provide sequential numbers for all messages in a forum thread.
• Add support for fenced code blocks and improved hyperlink processing to the markdown formatter.
• Add support for hyperlinks to wiki pages in the markdown formatter.
• Enhance the /stat page so that it gives the option to show a breakdown of forum posts.
• The special check-in name "merge-in:BRANCH" means the source of the most recent merge-in from the parent branch of BRANCH.
• Add hyperlinks to branch-diffs on the /info page and from timelines of a branch.
• Add graphical context on the /vdiff page.
• Uppercase query parameters, POST parameters, and cookie names are converted to all lowercase and entered into the parameter set, instead of being discarded.
• Change the default hash policy to SHA3.
• Timeout CGI requests after 300 seconds, or some other value set by the "timeout:" property in the CGI script.
• The check-in lock interval is reduced from 24 hours to 60 seconds, though the interval is now configurable using a setting. An additional check for conflicts is added after interactive check-in comment entry, to compensate for the reduced lock interval.
• Performance optimizations.
• Many documentation improvements.

Changes for Version 2.9 (2019-07-13)

• Added the fossil git export command and instructions for creating a GitHub mirror of a Fossil project.
• Improved handling of relative hyperlinks on the /artifact pages for wiki. For example, hyperlinks and the lizard <img> now work correctly for both /artifact/2ff24ab0887cf522 and /doc/0d7ac90d575004c2415/www/index.wiki.
• Enhancements to the timeline graph layout, to show more information with less clutter.
• Added tool-tips to the /timeline graph. On by default but can be disabled by setting the "Tooltip dwell time" to 0 in the timeline configuration.
• Copy buttons added to various check-in hash and branch name links.
• Double-clicking on a /timeline graph node now jumps to the /info page for the check-in. So, repurpose the timestamp hyperlink to show all activity around that check-in in time.
• Added the fossil touch command, and the --setmtime option on the fossil open and fossil update commands.
• Many documentation enhancements.
• For the "fossil update" and "fossil checkout" commands, if a managed file is removed because it is no longer part of the target check-in and the directory containing the file is empty after the file is removed and the directory is not the current working directory and is not on the empty-dirs list, then also remove the directory.
• Update internal Unicode character tables, used in regular expression handling, from version 11.0 to 12.1.
• In "fossil regexp", "fossil grep" and the TH1 "regexp" command, the -nocase option now removes multiple diacritics from the same character (derived from SQLite's remove_diacritics=2)
• Added the /secureraw page that requires the complete SHA1 or SHA3 hash, not just a prefix, before it will deliver content.
• Accept purely numeric ISO8601 date/time strings as long as they do not conflict with a hash. Example: "20190510134217" instead of "2019-05-10 13:42:17". This helps keep URLs shorter and less complicated
• Support both "1)" and "1." for numbered lists in markdown, as commonmark does.
• The sync and clone HTTP requests omit the extra /xfer path element from the end of the request URI. All servers since 2010 know that the HTTP request is for a sync or clone from the mimetype so the extra path element is not needed.
• If an automatic sync gets a permanent redirect request, then update the saved remote URL to the new address.
• Temporary filenames (for example used for external "diff" commands) try to preserve the suffix of the original file.
• Added the /thisdayinhistory web page.
• Enhanced parsing of /timeline query parameters "ymd=", "ym=", and "yw=". All arguments are option (in which case they default to the current time) and all accept ISO8601 date/times without punctuation.
• Automatically disapprove pending moderation requests for a user when that user is deleted. This helps in dealing with spam-bots.
• Improvements to the "Capability Summary" section in the Security Audit web-page.
• Use new "ci-lock" and "ci-lock-failed" pragmas in the sync protocol to try to prevent accident forks caused by concurrent commits when operating in auto-sync mode.
• Fix a bug (details) that can cause repository databases to be overwritten with debugging output, thus corrupting the repository. This is only a factor when CGI debugging is enabled, and even then is a rare occurrence, but it is obviously an important fix.

Changes for Version 2.8 (2019-02-20)

• Show cherry-pick merges as dotted lines on the timeline graph. → The "fossil rebuild" command must be run to create and populate the new "cherrypick" table in the repository in order for this feature to operate.
• Add the ability to associate branches, check-ins, and tags with specially-named Wiki pages. This gives the ability to better document branches and tags, and provide more documentation on check-ins beyond the check-in comment. The associated Wiki is automatically displayed on /info pages for check-ins, and on /timeline?r=BRANCH and /timeline?t=TAG pages for branches and tags. This feature is on by default, but can be disabled in on the Admin/Wiki page.
• Enhance the repository list page (shown for example by "fossil all ui") so that it shows the name and last check-in time for each project. The implementation of the repository list page is now broken out into a separate source file (repolist.c).
• Allow users with Forum Supervisor permission ('6') to add Forum Write Trusted permission ('4') to users as they are approving a forum post by that user.
• When running a bisect, report the number of check-ins still in the search range and the estimated number of bisect steps remaining. Do this at each step of the bisect.
• Provide a permanent link to a bisect timeline using the bid= query parameter.
• Make the chronological forum display feature available to all users, and make it the default format on mobile devices.
• Break out Wiki setup into a separate /setup_wiki page, accessible on the standard menus through Admin/Wiki.
• Add "Next" and "Previous" buttons on the /wdiff page, allowing the user to step through the versions of a wiki page.
• Improve the display of the /whistory page.
• Omit the "HH:MM" timestamps on timeline graphs on narrow-screen devices, to improve horizontal space uses. This helps make Fossil more mobile-friendly.
• Enhance /wcontent to show a sortable list of Wiki pages together with the number of revisions and the most recent change time for each page.
• Hyperlinks to Wiki pages on the /timeline go to the specific version of the Wiki page named in the timeline, not to the latest version.
• Enhancements to the "amend", "tag", and "reparent" commands, including adding options --override-date, --override-user, and --dry-run.
• Add the global --comment-format command-line option and the comment-format setting to control the display of the command-line timeline.
• Change the "fossil reparent" command so that it only works from within an active checkout.
• On the /setup_ucap_list, show administrators how many users have each capability. The counts are a hyperlink to the /setup_ulist page showing the subset of users that have that capability.
• Provide the ability to redirect all HTTP pages to HTTPS. Formerly one could cause this to occur for the /login page only. That option still exists, but the redirect can now also be done for all pages.
• "Compress" the built-in javascript by omitting comments and leading and trailing whitespace.
• Detect when the repository used by a checkout is swapped out for a clone that uses different RID values, and make appropriate adjustments to the checkout database to avoid any problems.
• Add the backoffice-disable setting to completely disable the backoffice feature.
• Update the built-in SQLite to version 3.27.1.
• Various other small enhancements to webpages and documentation.

Changes for Version 2.7 (2018-09-22)

• Add the email alerts feature for commits, ticket changes, wiki changes, forum posts, and announcements. This is still a work in progress. It is functional, but it is not as easy to setup and use as it ought to be.
• Add the discussion forum feature.
• Add new user capabilities letters needed to support alerts and forum. Formerly, user capabilities were letters from [a-z], but with the enhancements, the supply of lower case letters was exhausted. User capabilities are now letters in [a-zA-Z0-9].
• The built-in skins are now responsive, providing better layout on small screens, including mobile devices.
• The default skin now includes a hamburger menu that is generated by the /sitemap page.
• All of the built-in skins now use a Content Security Policy (CSP) to help prevent cross-site injection and forgery attacks. There are no known vulnerabilities in Fossil. The added CSP does not fix anything; it merely adds another layer of defense.
• The /sitemap and other list pages show as multiple columns if the viewing window is wide enough.
• There is an optional "js" file for each skin that can be used to hold javascript. This file can be loaded by reference or can be included in the header or footer.
• Add the backoffice.
• Update internal Unicode character tables, used in regular expression handling, from version 10.0 to 11.0.
• Improvements to the "Security Audit" administration page
• Add the fossil branch current command.
• Add the grep command.
• Update the built-in SQLite to version 3.25.1.
• Some code and interfaces are in place to support sending and receiving email directly via SMTP, but this feature is not yet complete or ready for production use.
• The `mv-rm-files` setting is now compiled into Fossil in the default Fossil configuration; no longer must you say ./configure --with-legacy-mv-rm to make it available. The setting remains disabled by default, however, so you must still say fossil set mv-rm-files 1 to enable it on each repository where you want hard mv/rm behavior.

Changes for Version 2.6 (2018-05-04)

• Fix a bug that was causing crashes while trying to clone the TCL repository. This fix is the main reason for the current release.
• Added the new "Classic" timeline viewing mode. "Classic" is the same as "Verbose" in the previous release. The "Verbose" mode is now like "Compact" except the extra check-in details are shown by default.
• Add support for ETags:, Last-Modified:, and If-Modified-Since: cache control mechanisms.
• Enhance the /tarball, /zip, and /sqlar pages so that the checkin name to be downloaded can be expressed as part of the URI, and without the need for query parameters.
• On the /timeline webpage, add the days=N query parameter and enhance the ymd=DATE and yw=DATE query parameters to accept 'now' as an argument to show the latest day or week.
• In the web page that comes up in response to the fossil all ui command, show the last modification time for each repository, and allow click-to-sort on the modification time column.
• In the tarball cache replacement algorithm, give extra weight to tarballs that have been accessed more than once.
• Additional defenses against web-based attacks. There have not been any known vulnerabilities. We are just being paranoid.
• Update the built-in SQLite to an alpha version of 3.24.0.

Changes for Version 2.5 (2018-02-07)

• Numerous enhancements to the look and feel of the web interface. Especially: Added separate "Modern", "Compact", "Verbose", and "Columnar" view options on timelines.
• Common display settings (such as the "view" option and the number of rows in a timeline) are held in a cookie and thus persist across multiple pages.
• Rework the skin editing process so that changes are implemented on one of nine /draft pages, evaluated, then merged back to the default.
• Added the Ardoise skin.
• Fix the "fossil server" command on Unix to be much more responsive to multiple simultaneous web requests.
• Use the IPv6 stack for the "fossil ui" and "fossil server" commands on Windows.
• Support for SQL Archives as a download option.
• Fossil now automatically generates the <html><head>...</head><body> at the beginning of each web page if the configurable header lacks a <body> tag.
• Added the /artifact_stats page, currently accessible only by the administrator.
• Upgrade to the latest versions of SQLite and OpenSSL.
• Improved key bindings on the Tk diff screen generated by "fossil diff --tk".

• When cloning a repository, the user name passed via the URL (if any) is now used as the default local admin user's name.
• Enhance the SSH transport mechanism so that it runs a single instance of the "fossil" executable on the remote side, obviating the need for a shell on the remote side. Some users may need to add the "?fossil=/path/to/fossil" query parameter to "ssh:" URIs if their fossil binary is not in a standard place.

• Added support for unlimited line lengths in side-by-side diffs.
• New --close option to fossil commit, which immediately closes the branch being committed.
• Added chart option to fossil bisect.

Changes For Version 1.26 (2013-06-18)

• The argument to the --port option for the fossil ui and fossil server commands can take an IP address in addition to the port number, causing Fossil to bind to just that one IP address.
• After prompting for a password, also ask if that password should be remembered.
• Performance improvements to the diff engine.
• Fix the side-by-side diff engine to work better with multi-byte Unicode text.
• Color-coding in the web-based annotation (blame) display. Fix the annotation engine so that it is no longer confused by time-warps.

• Enhanced defenses that prevent spiders from using excessive CPU and bandwidth.
• Consistent use of the -n or --dry-run command line options.
• Win32: Fossil now understands Cygwin paths containing one or more of the characters "*:<>?|. Those are normally forbidden in win32. This means that the win32 fossil.exe is better usable in a Cygwin environment. See http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars.
• Cygwin: Fossil now understands win32 absolute paths starting with a drive letter everywhere. The default value of the "case-sensitive" setting is now FALSE, except when case-sensitivity is enabled in the Windows kernel. See http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive
• Enhancements to /timeline.rss, adding more flags for filtering results, including the ability to subscribe to changes made to individual tickets. For example: /timeline.rss?y=t&tkt=12fceeec82.

• ssh:// and file:// protocols now ignore proxy settings.
• Added /hash-color-test web page.
• Cherry-pick merges are recorded internally (though no yet displayed on the timeline graph.)
• Bring in the latest versions of SQLite, zlib, and autosetup from upstream.

Changes For Version 1.25 (2013-02-16)

• Enhancements to ticket processing. There are now two tables: TICKET and TICKETCHNG. There is one row in TICKETCHNG for each ticket artifact. Fields from ticket artifacts go into either or both of TICKET and TICKETCHNG, whichever contain matching column names. Default ticket edit and viewing scripts are updated to use TICKETCHNG. The TH1 scripting language is enhanced to support this, including the new "query" command for doing SQL queries against the repository database. All changes should be backwards compatible.
• Add the ability to moderate ticket and wiki changes. Unmoderated changes do not sync and may be deleted by the moderator if found to contain spam or other objectionable content.
• Add javascript so that clicking on a node of the timeline graph selects that node. Then clicking on a second node shows a diff between the two nodes. Clicking on the selected node unselects it.
• Warn of unresolved merge conflicts in "fossil status" and disallow commits of unresolved conflicts unless the --allow-conflict option is used.
• Add javascript so that clicking on column headers in a ticket report sorts by the indicated column.
• Add the "fossil cat" command which is basically an alias for "fossil finfo -p".
• Hyperlinks with the class "button" are rendered as submenu buttons on embedded documentation.
• The check-in comment editor on Windows now defaults to NotePad.exe.
• Correctly deal with BOMs in check-in comments. Also attempt to convert check-in comments to UTF8 from other encodings.
• Allow the deletion of multiple stash entries using multiple arguments to the "fossil stash rm" command.
• Enhance the "fossil server DIRECTORY" command to serve static content files contained in DIRECTORY. For security, only files with a recognized suffix (such as *.html, *.jpg, *.txt, etc) will be delivered as static content, and *.fossil files are not on the list of recognized suffixes. There are additional restrictions on the names of the files.
• Allow the "fossil ui" command to specify a directory as long as the the --notfound option is used.
• Add a configuration option that causes timeline messages to be rendered as text/x-fossil-plain (which is the same as text/plain except that hyperlinks inside of [...] are decorated.)
• Only decorate [...] in check-in comments and tickets if the contented text really is a valid hyperlink target.
• Improvements to the side-by-side diff algorithm, for a more human-friendly display in some complex cases.
• Added [utime] and [stime] commands to TH1. These commands can be used for things such as displaying the page rendering time in the footer.
• Add the ability to pass command-line options of "fossil rebuild" to "fossil all rebuild".
• Add the --deanalyze option to "fossil rebuild" (and "fossil all rebuild")
• Do not run the graphical merging tool nor leave merge-droppings after a dry-run merge. Display an improved merge-summary message at the end of the merge.
• Add options to "fossil commit" to override the various sanity checks. Options added: --allow-empty, --allow-fork, --allow-older, and --allow-conflict.
• Optionally require a CAPTCHA (controlled by a setting on the Admin/Access webpage) when a user who is not logged in tries to edit wiki, or a ticket, or an attachment.
• Improvements to the "ssh://" sync protocol, to help it move past noisy motd comments.
• Add the uf=FILE-SHA1-HASH query parameter to the timeline, causing the timeline to show only check-ins that contain the specific file identified by FILE-SHA1-HASH. ("uf" stands for "uses file".)
• Enhance the file change annotator so that it follows the file across name changes.
• Fix the server-side of the sync protocol so that it will not generate a delta loop when a file changes from its original state, through two or more intermediate states, and back to the original state, all within a single sync.
• Show much less output during a sync operation, unless the --verbose option is used.
• Set the action= attribute of <form> elements using javascript, as an addition defense against spam-bots.
• Disallow invalid UTF8 characters (such as characters in the surrogate pair range) in filenames.
• Judge the UserAgent strings issued by the NetSurf webbrowser to be coming from a human, not from a bot.
• Add the zlib sources to the Fossil source tree (under compat/zlib) and use those sources when compiling on (Windows) systems that do not have a zlib library installed by default.
• Prompt the user with the option to convert non-UTF8 files into UTF8 when committing.
• Allow the characters *[]? in filenames.
• Allow the --context option on diff commands to have a value of 0.
• Added the "dbstat" command.
• Enhanced "fossil merge" so that if the VERSION argument is omitted, Fossil tries to merge any forks of the current branch.
• Improved detection of forks in a commit race.
• Added the --analyze option to "fossil rebuild".

Changes For Version 1.24 (2012-10-22)

• Added support for WYSIWYG editing of wiki pages. WYSIWYG is turned off by default and can be turned on by setting a configuration option.
• Allow style= attribute to occur in HTML markup on wiki pages.
• Added the --tk option to the "fossi diff" and "fossil stash diff" commands, causing color-coded diff output to be displayed in a Tcl/Tk GUI window. This option only works if Tcl/Tk is installed on the host.
• On Windows, make the "gdiff" command default to use WinDiff.exe.
• Update the "fossil stash" command so that it always prompts for a comment if the -m option is omitted.
• Enhance the timeline webpages so that a=, b=, c=, d=, p=, and dp= query parameters (and others) can all accept any valid check-in name (such as branch names or labels) instead of just SHA1 hashes.
• Added the "fossil stash show" command.
• Added the "fileage" webpage with links to this page from the check-in information page and from the file browser.
• Added --age and -t options to the "fossil ls" command.
• Added the --setmtime option to "fossil update". When used, the mtime of all managed files is set to the time when the most recent version of the file was checked in.
• Changed the "vdiff" webpage to show the complete text of files that were added or removed (the equivalent of using the -N or --newfile options with the "fossil diff" command-line.)
• Added the --temp option to "fossil clean" and "fossil extra", causing those commands to only look at temporary files generated by Fossil, such as merge-conflict reports or aborted check-in messages.
• Enhance the raw page download so that it can guess the mimetype of attachments based on the filename.
• Change the behavior of the from= and to= query parameters on the timeline page so that by default the path between the two specified check-ins avoids merges.
• Add the --baseurl option to "fossil server" and "fossil http" commands, so that those commands can be used with reverse proxies.
• If unable to determine the command-line user, do not guess. Instead issue an error message. This helps prevent check-ins from accidentally occurring under the wrong username.
• Include branch information in the output of file change listings (the "finfo" webpage).
• Make the simplified view of file history, rather than the full view, the default.
• In the "fossil configuration" command, allow the "css" option for synchronizing, importing, or exporting just the CSS file. This makes it easier to share CSS files across repositories by exporting from one and importing to another.
• Add the (unsupported) "fossil test-orphans" command.
• Add the --template option to the "fossil init" command, to facilitate creating new repositories based on a template repository.
• Add the diff-binary setting, which if enabled causes binary files to be passed to the "gdiff" command for it to deal with, rather than simply printing a "cannot diff binary files" error.
• Add the --unified option to the "fossil diff" command to force a unified diff even if the --tk option (which normally implies a side-by-side diff) is used.
• Present a choice of nearby branches and versions to diff against on the check-in information page.
• Add the --force option to the "fossil merge" command that will force the merge to occur even if it would be a no-op. This is sometimes useful for documentation purposes.
• Add another built-in skin: "Enhanced Default". Other minor tweaks to the existing skins.
• Add the "urllist" webpage, showing a list of URLs by which a server instance of Fossil has been accessed. Requires "Administrator" privileges. A link is on the "Setup" main page.
• Enable dynamic loading of the Tcl runtime for installations that want to use Tcl as part of their configuration. This reduces the size of the Fossil binary and allows any version of Tcl 8.4 or later to be used.
• Merge the latest SQLite changes from upstream.
• Lots of minor bug fixes.

Changes For Version 1.23 (2012-08-08)

• The default checkout database name is now ".fslckout" instead of "_FOSSIL_" on Unix. Both names continue to work.
• Added the "fossil all changes" command
• Added the --ckout option to the "fossil all list" command
• Added the "public-pages" glob pattern that can be configured to allow anonymous users to see embedded documentation on sites where source code should not be accessible to anonymous users.
• Allow multiple --tag options on the same "fossil commit" command.
• Change the meaning of the --bgcolor option for "fossil commit" to only change the color for that one commit. The new --branchcolor option is available to set a persistent background color.
• Add the branch= query parameter to the vdiff page and the --branch option to the "fossil diff" command.
• Check-in names of the form "root:BRANCH" now refer to the origin of the branch. Hence to see all changes in a branch, use "fossil diff --from root:BRANCH --to BRANCH". The --branch option on the diff command is an alias for the same.
• Add the ability to configure ad-units to be displayed between the menu bar and the content.
• Add the ability to set a background image as part of server configuration.
• Allow partial commits of cherrypick merges.
• Updates against an uncommitted merge are now a warning, not a fatal error.
• Prompt the user to continue if a check-in comment is unedited.
• Fixes to case sensitivity settings with the /dir webpage.
• Repositories now try to remember the locations of all checkouts and web-access URLs and display this information with the "fossil info $REPO" command.
• Improved defense against spiders: The src= attribute of <a> elements is set using javascript after the page loads.
• Enhanced formatting of the user list page.
• If a file named in "fossil add" is missing, that is now a warning instead of a fatal error.
• Fix side-by-side diff so that it displays correctly with multi-byte UTF8 characters.
• Performance improvements in the diff logic.
• Other performance tweaks and documentation updates.

Changes For Version 1.22 (2012-03-17)

• Greatly improved "diff" processing including the new --brief option, partial line matching, colorized in-line diffs, and better performance.
• Promote "allow-symlinks" to a versionable setting
• Harden the CGI processing logic against DOS attacks
• Add the ability to run TH1 scripts after sync requests
• Store the repository name in _FOSSIL_ as it is type in the "open" command, possibly as a relative pathname.
• Make ".fslckout" the alternative name for the "_FOSSIL_" file.
• Change the "ssh:" transfer method to allow all access regardless of user permission.
• Improvements to the timeline messages associated with tag changes. (Requires a "fossil rebuild" to take effect.)
• Various additions and fixes for the JSON API.
• Improved merge-with-rename handling.
• --cherrypick merges use their origin's commit message by default.
• Added support for multiple concurrent logins per user.
• Update to use SQLite version 3.7.11.
• Various minor bug fixes.

Changes For Version 1.21 (2011-12-13)

• Added side-by-side diffs in the command-line interface
• Automatically enable hyperlinks if the UserAgent string in the HTTP header suggests that the requestor is a human and not a bot.
• Show only commonly used commands with "fossil help". Use "fossil help --all" to see the complete list now.
• Improvements to the "stash" command: (1) Stash all files, not just those below the working directory. (2) Add the --detail option to "list". (3) Confirm before "drop --all". (4) Add the "help" subcommand.
• Add an Admin/Access setting to change the number of octets of the IP address that are saved in login cookies - allowing this setting to be changed to zero
• Promote the "test-md5sum" command to "md5sum".
• Added the "whatis" command.
• Stop showing the server-code in status outputs - it is no longer used for anything.
• Added a compile-time option (--with-tcl) to build in full Tcl scripting support via integration with TH1.
• Merged the JSON branch into trunk. Disabled by default. Enabled by a compile-time option. Probably it will be enabled by default in some future release.
• Update to use SQLite version 3.7.9 plus the alignment fix for Sparc. align
