 - Pure SDL render path for when OpenGL 2 is unavailable (thanks Higor Eurípedes)
 
*Bugfixes*

 - GDB remote debugging works again
 - Fixed a name conflict that prevented vgmplay from being built on OS X
 
*Other Changes*

 - Windows build now includes the disassemblers, VGM player and save state viewer

0.3.0
-----
*New Features*

 - 32-bit x86 CPUs are now supported
 - BlastEm is now available for OS X and Windows
 - Finished support for the Sega mapper used by Super Street Fighter 2
 - Added support for EEPROM saves
 - Added support for large flat-mapped ROMs (used by some homebrew ROMS)
 - New 68K debugger command bt (backtrace)
 - I/O devices (gamepads and other peripherals) can now be configured in blastem.cfg
 - VDP Debugger views from before 0.1.0 have been restored
 
*Bugfixes*

 - Partial emulation of floating bus bits for certain I/O regs (fixes Super Offroad 2)
 - Fixed shadow/highlight mode
 - Implemented AM and fixed LFO update speed
 - Fixed negative detune values
 - Corrected register to operator mapping for channel 3 special mode
 - Initial stab at emulating cycles being stolen from the 68K when the Z80 accesses its bus
 - Better handling of creating a savestate in "uncooperative" games/demos
 - Implemented VSCROLL latching
 - Fixed a bug that would corrupt the Z80's SP register in some situations
 - Fixed PAL flag in VDP status register
 - Fixed HV counter
 - Fixed flag calculation for RRA, RRCA, RLA and RLCA

*Other Changes*

 - Upgraded to SDL2
 - Dropped suport for the non-OpenGL render path
 - Linux builds should now work on something other than the specific version of Ubuntu I happen to be using at build time

- Approximate wait state behavior when the Z80 accesses the 68K's bus
- Implemented HV counter latch
- Implemented sprite overflow and collision flags
