XFree86 4.5.99.901 (6 March 2006)
 234. Fix an error in the handling of PRIVS_ELEVATED (David Dawes, reported
      by Takaaki Nomura).
 233. Check in xterm for NULL return from XftFontMatch(), and check for
      NULL pattern in XftFontOpenPattern() (David Dawes).
 232. Avoid having xinit kill a slow exiting X server with SIGKILL.  Instead
      use SIGINT for slowly exiting X servers, and modify the X server
      to use a faster, but still hardware-clean, exit path when it
      receives an interrupt signal (David Dawes).
 231. Install the manual page source as well as the formatted manual pages
      on NetBSD (David Dawes).
 230. Fix a problem on NetBSD where a build will continue after an error
      (David Dawes).
 229. XFree86 loader enhancments:
      - Per-module export symbol lists.
      - Improved symbol hash.
      - A mechanism for specifying the scope of symbols.
      - Keep track of relocations, and undo them when they become unresolved
        on module unload, and recalculate them when they change on module
        load.
      - Check relocations on each module load/unload, ensuring that function
        references that are unresolved at any time are always mapped to the
        catch-all function preventing calls into nowhere.
      - Efficient handling of invariant relocations.
      - Cleanup/update the memleak stack trace code, and print a stack
        trace when an unresolved function is called or when XFree86 aborts.
      - Update the catch-all function to identify the unresolved function.
      - Read the XFree86 executable's symbol table in order to get the
        most useful stack traces, and use dladdr(), where available,
        for shared library references.
      - Cleanup and unify debug messages for the loader components.
      - Allow for module-instance-specific referenced and required
        symbols lists, so that a module's requirements can be removed
        when it is unloaded.
      - Update the ati driver to make use of some of the new loader
        functionality.
      - General loader cleanups, including removing some redundancies.
      - Don't build the coff loader on platforms that it doesn't support.
      (X-Oz Technologies, David Dawes).
 228. Remove unused beta/expiry code from the XFree86 server (David Dawes).
 227. Add user_data field to Xaw's simpleWidgetClass (Bugzilla #1659,
      Alexander Pohoyda)
 226. Fix some X server man page typos (Bugzilla #1658, Nicolas Joly).
 225. Fix some build/warnings on NetBSD (David Dawes).
 224. TinyX build fixes, including one for Linux systems that don't provide
      <sys/io.h>, e.g. libc5 among others (Marc La France).
 223. Improve accuracy of atimisc's calculations that are based on a 29.5 MHz
      reference clock (Marc La France).
 222. A setuid xterm doesn't also need to be setgid (Marc La France).
