+* New parsers:
+  * ICO: Windows icons and cursors. Supports most icons and cursors designed
+    for Windows 3.x and later (including Windows Vista PNG-format icons),
+    plus the old Windows 1.x format. Only the "best" version for each icon
+    is selected for thumbnailing. (Largest size and highest color depth.)
+    * Icon thumbnailing is not actually enabled on Windows and Linux systems
+      at the moment, since it may conflict with system icon handling.
+      It's mostly only usable for rpcli and for use as a subclass elsewhere.

     * Fixes #450: X360 - Non-Latin Titles appearing as mojibake

+  * EXE: The application icon can now be extracted using rpcli.
+  * ISO: Thumbnailing for ISO images with AUTORUN.INF and a specified icon
+    from a .ico, .exe, or .dll file is now supported.
+  * ISO: Joliet file systems are now partially supported. This was added to
+    handle older Windows disc images that use a long filename for the icon,
+    and the disc is authored with Joliet for long filenames but an old version
+    of ISO-9660, resulting in 8.3 filenames in the ISO-9660 directories.
