 -0.?.? (to be announced) "spectral gravity"
 -------------------------------------------
 +---------------------------------------------
 +0.5.0 (to be announced) "invertible validity"
 +---------------------------------------------
  
 +      - The sideband compatibility code has been removed, hence
 +        sideband connections (introduced in 0.4.11) are now mandatory.
 +      - Addblob commands can produce output.
 +      - The stat command no longer sends garbage when para_server was
 +        compiled against libgcrypt.
 +      - Dependencies for gengetopt files are computed automatically.
 +        This eliminates a constant source of build bugs.
 +      - The setatt command now accepts file name patterns rather than only
 +        path names.
++      - overview.pdf is now based on dia, a simple diagram creation program.
++        The new version is much more detailed and contains descriptions of
++        the various programs of the paraslash package.
 +
 +--------------------------------------
 +0.4.13 (2013-07-29) "spectral gravity"
 +--------------------------------------
 +
 +One more 0.4.x release before the API-breaking changes for 0.5.0 go
 +in. The main features of this release are the ogg/opus audio format,
 +and UTF-8 support, but it includes also tons of other improvements
 +and fixes all over the place.
 +
 +      - New audio format: ogg/opus.
        - UTF8 support for para_gui and the mp3 audio format handler.
        - Scheduler improvements and fixes.
        - The obsolete gettimeofday() function has been replaced
          by clock_gettime() on systems which support it.
 +      - Speed and usability improvements for para_gui.
 +      - para_client now restores the fd flags of stdin and stdout
 +        on shutdown.
 +      - Improved manual pages.
 +      - Consistent version strings for all executables.
 +      - Reduced dependencies on generated files result in fewer
 +        recompilations on changes.
 +      - Performance improvements for the compress filter.
 +      - Improved downloads web page.
