Sorry, wrong branch! started changelog for 1.20 release. Closed-Leaf check-in: a942086390 user: stephan tags: declined
2011-10-15
10:17
A very simple fix to the annotate memory leak problem. check-in: 9929bab702 user: drh tags: trunk
2011-10-14
22:20
Making 'fossil merge' also report a conflict for extra files overwritten. Like [60c6197c8a], but for the merge operation. Related to ticket [953031915f]. check-in: bb49278a8a user: viriketo tags: declined
16:11
Merging the annotate_noleak changes, about removing an important memory leak in the annotate operation. It also fixes some blob behaviour in blob.c and content.c. <b>Update:</b> Removed from trunk. Replaced by the must simpler fix at [9929bab702f99839ee] check-in: 409f370a6d user: viriketo tags: declined
00:06
Add /*sort*/ marks to some SQL queries to disable warnings about sorting without an index. check-in: fff43ebb5b user: drh tags: trunk
2011-10-13
23:47
Provide an option to enable the /test_env URL for all users. Optionally display cookie values in the /test_env URL. check-in: 4d32db8ef8 user: drh tags: trunk

<h2>Changes For Version 1.20 (upcoming)</h2>
  *  Added side-by-side diffs in HTML interface
  *  Fixed annotate to show "more relevant" versions of lines in some cases.
  *  Timeline now shows tag changes (requires rebuild)
  *  Added support for symlinks.
  *  New command: ticket history
  *  Several SSL improvements. Disabled SSLv2 in HTTPS client.
  *  Added -R REPOFILE support to several more CLI commands.
  *  Updated sqlite3 to 3.7.9.
  *  Generated tarfiles now have constant timestamps, to avoid them having a new checksum each time they are generated.
  *  A number of minor HTML-related tweaks and fixes.
  *  Added --args FILENAME global CLI argument to import arbitrary CLI arguments from a file (e.g. long file lists).
  *  Fixed significant memory leak in annotation of files with long histories.
  *  Added warnings when a merge operation overwrites local copies (UNDO is available, but previously this condition normally went silently unnoticed).
