+  * New Features
+    ------------
+    * Export drawings:
+      * GIF export option from the Open -> Slideshow dialog.
+        (Closes https://sourceforge.net/p/tuxpaint/feature-requests/191/)
+        * Utilizes "gifenc", public domain by Marcel Rodrigues:
+          https://github.com/lecram/gifenc
+        * Depends on "libimagequant", from the "pngquant2" project:
+          https://github.com/ImageOptim/libimagequant
+          (GPL v3 or later, for Free/Libre Open Source Software)
+      * Single image (PNG) export from the Open dialog.
+        (Closes https://sourceforge.net/p/tuxpaint/feature-requests/192/)
+      * Both utilize XDG user dirs settings, if available, to determine
+        where to store them, or "~/Pictures", otherwise.  In those cases,
+        files are stored in a new "TuxPaint" subdirectory.
+      * The "--exportdir" option can be used to override the default
+        location (but a "TuxPaint" subdir. will NOT be placed there).
+
+  * Ports & Building
+    ----------------
+    * Corrections for Haiku not opening saved files.

+  * Bug Fixes
+    ---------
+    * Mended issue where stamp descriptions were not loading
+      when "getenv()" (e.g., "getenv("LANGUAGE")") returned an
+      empty string, rather than a NULL.
+
+    * Mended bug where corrupt text would appear as stamp
+      descriptions, if we failed to know what language to use
+      (see above).
