 Changelog
 ---------
+1.40
+  + Added support for SVP (Sega Virtua Processor) to emulate Virtua Racing,
+    wrote ARM recompiler and some HLE code for VR. Credits to Exophase and
+    Rokas for various ideas.
+  * Changed config file format, files are now human-readable. Game specific
+    configs are now held in single file (but old game config files are still
+    read when new one is missing).
+  * Fixed a bug where some key combos didn't work as expected.
+  * Fixed a regression in renderer (some graphic glitches in rare cases).
+  * Adjusted fast renderer to work with more games, including VR.
+  * Fixed a problem where SegaCD RAM cart data was getting lost on reset.
+  * Greatly reduced SegaCD FMV game slowdowns by disabling read-ahead in the
+    Linux kernel and C library (thanks to Rokas and Exophase for ideas again).
+    Be sure to keep "ReadAhead buffer" OFF to avoid slowdowns.
+  + PicoDrive now comes with a game config file for some games which need
+    special settings, so they should now work out-of-the-box. More games will
+    be added with later updates.
+
 1.35b
   * PSP: mp3 code should no longer fail on 1.5 firmware.
   + PSP: added gamma adjustment option.
