* Mega Drive: reset does not cancel 68K bus requests
* Mega Drive: 68K is not granted bus access on Z80 reset
* Mega Drive: CTRL port is now read-write, maintains value across controller changes

* SPC700: improved all cycle timings to match results observed by Overload with a logic anaylzer
* Super Famicom: SMP uses a separate 4x8-bit buffer for $f4-f7; not APU RAM [hex_usr]
* Super Famicom: SMP TEST register is now finally 100% fully emulated [byuu, AWJ]
* Game Boy Advance: DMA can run between CPU instruction cycles
* Game Boy Advance: added 2-cycle delay between DMA activation and transfers
* higan: improved aspect ratio correction accuracy at higher video scaling sizes
* higan: overscan masking will now actually crop the underlying video instead of just blanking it
* Mega Drive: center video when overscan is disabled
* higan: added increment/decrement quick save slot hotkeys
* Game Boy Advance: fixed wave RAM nibble ordering (fixes audio in Castlevania, Pocket NES) [Cydrak, dwedit]
* higan: added new adaptive windowed mode: resizes the window to the current emulated system's size
* higan: added new integral scaling mode: resizes the window to fill as much of the screen as possible
* higan: main window is now resizable and will automatically scale contents based on user settings
* higan: fixed one-time blinking of the main window on startup caused by focus stealing bug
* ruby: fixed major memory leak in Direct3D driver
* ruby: added fullscreen exclusive mode to Direct3D driver
* Super Famicom: corrected latching behavior of BGnHOFS PPU registers
* higan: all windows sans the main viewport can be dismissed with the escape key now
* ruby: complete API rewrite; many audio drivers now support device selection
* higan: output frequency can now be modified
* higan: configuration settings split to individual menu options for faster access to individual pages
* ruby: improved WASAPI driver to event-driven model; more compatible in exclusive mode now
* libco: fix compilation of sjlj and fiber targets [Screwtape]
* ruby: added YV12 and I420 support to X-Video driver
* Game Boy: added TAMA emulation (RTC emulation is not working yet) [thanks to endrift for notes]
* Game Boy: correct data ordering of MMM01 ROMs (MMM01 ROMs will need to be re-imported into higan)
* Game Boy: store MBC2 save RAM as 256-bytes instead of 512-bytes (RAM is 4-bit; not 8-bit with padding)
* Game Boy: fixed a bug with RAM serialization in games without a battery
* Mega Drive: fix CRAM reads (fixes Sonic Spinball) [hex_usr]
* Game Boy: added rumble support to MBC5 games such as Pokemon Pinball
* Game Boy: added MBC7 emulation (accelerometer X-axis, EEPROM not working yet) [thanks to endrift for notes]
* hiro: macOS compilation fixes and UI improvements [MerryMage, ncbncb]
* Game Boy: added MBC6 emulation (no phone link or flash support; timing bugs in game still)
* Game Boy: HDMA syncs to other components after each byte transfer now
* Game Boy: disabling the LCD completely halts the PPU (fixes onscreen graphical corruption in some games)
* Mega Drive: added 6-button Fighting Pad emulation [hex_usr]
* 68K: TAS sets d7 when EA mode is a direct register (fixes Asterix graphical corruption)
* Game Boy: STAT mode is forced to zero when LCD is disabled (fixes Pokemon Pinball)
* LR35902: complete rewrite
* icarus: high-DPI is not supported on Windows yet; remove setting for consistency with higan window sizes
* hiro: added full support for high-DPI displays on macOS [ncbncb]
* ARM7TDMI: complete rewrite
* Super Famicom: disabled channels during HDMA initialization appear to set DoTransfer flag
* V30MZ: code cleanup
* Mega Drive: added optional TMSS emulation; disabled by default [hex_usr]
* ARM7TDMI: pipeline decode stage caches CPSR.T [MerryMage]
* ARM7TDMI: fixed timing of THUMB stack multiple instruction [Cydrak]
* higan: detect when ruby drivers crash; disable drivers on next startup to prevent crash loop
* Mega Drive: added automatic region detection (favors NTSC-J > NTSC-U > PAL) [hex_usr]
* Mega Drive: support 8-bit SRAM
* ARM7TDMI: PC should be incremented by 2 when setting CPSR.T via MSR instruction [MerryMage]
* ruby: add Windows ASIO driver support (does not work on some systems due to buggy vendor drivers)
* higan: default to safe drivers on a new install; due to instability with some optimal drivers
