<h2 id='v2_24'>Changes for version 2.24 (2024-04-23)</h2>

  *  Apache change work-around &rarr; As part of a security fix, the Apache webserver
     mod_cgi module has stopped relaying the Content-Length field of the HTTP
     reply header from the CGI programs back to the client in cases where the
     connection is to be closed and the client is able to read until end-of-file.
     The HTTP and CGI specs allow for this, though it does seem rude.
     Older versions of Fossil were depending on the Content-Length header field
     being set.  To work around the change to Apache, Fossil has
     been enhanced to cope with a missing Content-Length in the reply header.  See
     [forum:/forumpost/12ac403fd29cfc89|forum thread 12ac403fd29cfc89].
  *  [./customskin.md|Skin] enhancements:
     <ul>
     <li>  Reworked the default skin to make everything more readable: larger
           fonts, more whitespace, deeper indents to show hierarchy and to

     <li> Automatically highlight the endpoints for from=,to= queries.
     <li> Add the to2=Z query parameter to augment from=X,to=Y so that the
          path from X to Z is shown if Y cannot be found.
     </ul>
  *  Moved the /museum/repo.fossil file referenced from the Dockerfile from
     the ENTRYPOINT to the CMD part to allow use of --repolist mode.
  *  The [/uvlist] page now shows the hash algorithm used so that
     viewers don't have to guess.  The hash is shown in a fixed-width
     font for a more visually pleasing display.
  *  If the [/help?cmd=autosync|autosync setting] contains keyword "all",
     the automatic sync occurs against all defined remote repositories, not
     just the default.
  *  Markdown formatter: improved handling of indented fenced code blocks
     that contain blank lines.
  *  When doing a "[/help?cmd=add|fossil add]" on a system with case-insensitive

      atomic even if interrupted by a power loss or system crash.
      Automatic [./selfcheck.wiki | self-checks] verify that all aspects of
      the repository are consistent prior to each commit.
