 Changelog:\r
 \r
+0.9-2xb u1 (unofficial notaz release):\r
+- Fixed a problen in thread synchronization which caused deadlock after\r
+  some time.\r
+\r
+0.9-2xb u2 (unofficial notaz release):\r
+- Replaced non-working mmuhack.o with proper one, added cache flush calls\r
+  to avoid artifacts.\r
+\r
+0.9-2xb u3 (unofficial notaz release, released with permission):\r
+- Removed built-in CPU/LCD/RAM-Tweaker.\r
+- Improved usability of volume control.\r
+- Removed PSP-specific GUI options, adjusted help text.\r
+- Overclocking from menu now works, keep it at 200 if you don't want that\r
+  (if you want to overclock using launcher, for example).\r
+- Fixed centering-on-first-run problem.\r
+- 3:2 scaled option now does what it says.\r
+\r
 0.9-2xb: \r
 -- IMPORTANT-- If you're overwriting an old version, be sure to delete the\r
    gpsp.cfg file first, or be prepared to have a bunch of weird button\r
