The backend library to read freedesktop.org application menu files has been released updating important aspects.

• The libmenu-cache is made thread-safe. Thread-unsafe APIs are marked as deprecated now and should be never used in any multithreaded application.
• Added creation of HTML developers documentation. It is triggered by configure script option –enable-gtk-doc.
• The libmenu-cache is made more responsible by moving some time-critical operations into thread. Also it preloads saved cache file if it exists so it is available near instantly after menu_cache_lookup(). Caller still will get updates by adding notifier to the cache.
• Added automatic shutdown of menu-cached server after some inactivity timeout (i.e. all clients were unregistered).
• Fixed few memory problems (referencing errors and memory leaks).
• Fix for bug #3501347: use g_get_tmp_dir() instead of hardcoded “/tmp”.
• The libmenu-cache ABI bumped to 2.

menu-cache-0.4.0.tar.gz, sha1sum: f853d195cde1209873cc1f11bc401cce2cbef2f6

UPDATE: The release tar file is missing a file! Do not use it, grab 0.4.1 instead (or rather use the git repository).
