<h2>Changes for Version 2.16 (pending)</h2>
  *  [/brlist|List of branches] gained
     [/timeline?r=brlist-timeline|the facility] to select several
     branches and [./javascript.md#brlist|point a user] to the
     <tt>/timeline</tt> view that shows just these selected branches
     and the related check-ins.

<h2>Changes for Version 2.15 (2021-03-26) and Patch 2.15.1 on (2021-04-07)</h2>
  *  <b>Patch 2.15.1:</b> Fix a data exfiltration bug in the server.  <b>Upgrading to
     the patch is recommended.</b><p>
  *  The [./defcsp.md|default CSP] has been relaxed slightly to allow
     images to be loaded from any URL.  All other resources are still
     locked down by default.

…would pull the messages submitted since the last poll. Making the
gateway bidirectional should be possible as well, as long as it properly
uses SQLite transactions.

### <a id="brlist"></a>List of branches

Since Fossil 2.16 [`/brlist`](/brlist) page uses JavaScript to enable
selection of several branches for further study via `/timeline`.
Client-side script interactively responds to checkboxes' events
and constructs a special hyperlink in the submenu.
Clicking this hyperlink loads a `/timeline` page that shows
only these selected branches (and the related check-ins).

_Potential Workaround:_ A user can manually construct an appropriate
regular expession and put it into the "Tag Filter" entry of the
`/timeline` page (in its advanced mode).

## <a id="future"></a>Future Plans for JavaScript in Fossil

As of mid-2020, the informal provisional plan is to increase Fossil
UI's use of JavaScript considerably compared to its historically minimal
uses. To that end, a framework of Fossil-centric APIs is being developed
