"This update for fossil fixes the following issues :

  - fossil 2.12.1 :

  - CVE-2020-24614: Remote authenticated users with check-in
    or administrative privileges could have executed
    arbitrary code [boo#1175760]

  - Security fix in the 'fossil git export' command. 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.

  - Added the 'collapse' and 'expand' capability for long
    forum posts.

  - 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.

  - On the /timeline webpage, the combination of query
    parameters 'p=CHECKIN' and 'bt=ANCESTOR' draws all
    ancestors of CHECKIN going back to ANCESTOR.

  - 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.

  - Package the fossil.1 manual page.

  - fossil 2.11.1 :

  - Make the 'fossil git export' command more restrictive
    about characters that it allows in the tag names

  - Add fossil-2.11-reproducible.patch to override build
    date (boo#1047218)");
