 D2X-Rebirth Changelog
 
+20080225
+--------
+include/loadgl.h, main/newmenu.c, main/titles.c: Added definitions for OpenGL fucntions which might not be included in system headers; Cleaned and declared briefings palette hacks (EMULATING_D1 needs work!); Menu right border shadow was too wide;
+
 20080323
 --------
 main/kconfig.c, main/laser.c, main/menu.c, main/newmenu.c, main/playsave.c: Added lock status for mouse axis weapon cycling because of scaled mouse delta; Due to player feedback (any my opinion) making homer turn rate smaller to make them a bit harder to dodge; Preventing write of player data while Demo playback; Small code cleanup and corrections
