  . Hitachi SH-2/SH-4: Don't emit fast RAM accesses when the debugger is enabled
  . IBM PowerPC 4xx/6xx: Fixed debug flag test causing fast RAM accesses to be erroneously emitted (powerpc\ppcdrc.cpp). Hopefully fixes unusual breakpoint/watchpoint behaviour.
  . Intel 8257 DMA Controller: Various small improvements. Synchronize at a couple of critical points. Allow read side effects to be suppressed while debugging. Improved TC timing. Allow HLDA to abort DMA cycle. Don't clear request input state when device is reset.
  . Intel I386: Prevent (MESS) ISA-386U30 REV.2.2 from hanging MAME (i386\i386segs.hxx)

  . Motorola MC6801: More logging and reduced unneeded updates of Tx line
  . Texas Instruments TMS34020: Implemented CLIP and SETCDP opcodes (tms34010\34010ops.hxx). Fixed out of bounds read, when extra logging is enabled
  . Toshiba TLCS-90 MCUs: Separated TMP90840 and TMP90844 disassemblers (cpu\tlcs90\tlcs90.cpp)
  . Zilog Z180
    . Splitted generic Z180 device into several subtypes (Hitachi HD64180RP, Hitachi HD647180X MCU, Zilog Z80180 and Zilog Z8S180). HD647180X now has specific device emulation for the internal PROM, RAM and parallel ports.
    . Added internal clock divider for Z180 family and adjust CPU clocks in many drivers to compensate. Reduced logical address width to 16 bits.
- SOUND
  . Added position description to 'subwoofer' (emu\speaker.h)
  . Taito Ensoniq Sound System: Slight XTAL correction
  . Yamaha YMF278B OPL4: Allow scaling for FM DO2 output
- DEVICE
  . ADC0804 A/D Converter: Emulated ADC0804 and added device to various drivers (cischeat.cpp (armchmp2, scudhamm), nemesis.cpp (citybomb, hcrash), overdriv.cpp, polepos.cpp, segae.cpp, segahang.cpp, segaorun.cpp, segaxbd.cpp, tmnt.cpp, wallc.cpp and wecleman.cpp)
  . Cassette: Added bitwise operators for cassette_state (imagedev\cassette.cpp)
  . CXD1095 I/O Expander: Default clock to 0
  . Discrete Netlist
    . Switch to C++ streams. Removed the home-brew implementation pstreams and replaced those with C++ streams.
    . Fixed a number of minor issues and warnings. Removed const on return types.
    . Moved more code in headers and deleted some cpp files. Code simplification.
    . Fixed SUBMODEL. Moved to strongly typed matrix sort constant. Extend maximum matrix size to 512x512. Optionally do parallel processing based on total operations. Templatize GMRES solver loops.
    . Avoid duplication in solver parameter code. Matrix sort type is now a parameter.
    . Use unique_ptr where possible. GMRES update and new preconditioner. Maintenance and lint fixes.
    . Improved code readability and simplifications. kidniki uses frontiers again (speed improvement).
    . Separated solving linear systems from underlying matrix (netlist\plib\mat_cr.h)
    . Moved netlists out of driver code into audio/ or machine/ as nl_xxx.cpp files. Identified and documented extended validation.
    . Optimized the core queue dispatching logic. Minor performance increase. Fixed a number of bugs in parray. Now parray will be purely dynamic allocation with the number of elements passed in the constructor. Added noexpr where appropriate. Simplified the queue.
    . After the recent string of updates pongf performance increased again. Some fixes for the aligned memory operations.
    . Solver now uses dynamic allocation on systems larger than 512x512
    . Added support for line markers to the preprocessor and parser and for include processing to the preprocessor. Moved sources base type to plib to be used for preprocessor includes. This enables to include e.g. from rom memory regions.
  . Floppy: Changed Interrupt command logic based on WD1772 and VG93(1793 clone) decaps (machine\wd_fdc.cpp)
  . Intel 8251 USART: Modernized debug printouts
  . Intel 8253 PIT: Introduced logmacro.h based logging
  . Intel 8275 CRTC: Simplified read/write handlers
  . National Semiconductor INS8250 UART: Fixed cleared pending THRE interrupt. The code notes that reading the iir register "will clear the int if this is the source of the int" and the code cleared a pending THRE interrupt if it was *pending*. This causes a lost THRE interrupt for the SWTPC 8121 terminal firmware and this locks up the TX side of the terminal. This occurred regularly when the ISR read this register upon a higher priority RX pending interrupt. The documented operation has been reinterpreted as only clearly the THRE interrupt if THRE is the highest priority interrupt and so is the pending interrupt *causing* the interrupt. This fixes that lost THRE interrupt for the SWTPC 8121 terminal.
  . MB14241 Data Shifter: Simplified handlers
  . Motorola MC6845 CRTC: More logging and reduced (not eliminated) warning spam significantly at startup when register values doesn't make sense
  . OKI MSM5832 RTC: Simplified handlers
  . RS232 Port
    . Moved some initialization to a device_reset() function. Calling the line handlers, such as m_cts_handler() from the device_start() function is problematic as some of these handlers may wish to read ioports and that is not safe at this stage, so move these to a new device_reset() function.
    . Added DTR flow control to RS232 Null Modem. Some terminals use the DTR output for hardware flow control, so added that as another option.
  . Sega 16-bit hardware (segahang.cpp, segaorun.cpp, segas16a.cpp, segas16b.cpp, segas18.cpp, segaxbd.cpp, segaybd.cpp and system16.cpp)
    . Code cleanup, reorganization and decoupling.
    . Moved open_bus_r down into the 315-5195 mapper device (not 100% ideal, but the next best place). Splitted out 315-5195 mapper device into separate source file and modernized logging.
    . Moved remaining portion of sega_16bit_common_base (all to do with palettes) into video\segaic16.cpp
  . Tecmo Chained Sprites: Hardcode behavior based on visible width, not full screen width.

- Renamed (m21) to (mirco21)
- MAME
  . VIDEO RENDERING SYSTEM
    . Validate crystal values used for set_raw (emu\screen.h)
    . Added some sanity checks to video\sprite.cpp
  . MEMORY SYSTEM
    . Added rudimentary validity checking for address_space_config objects (emu\dimemory.cpp)
    . Added emu_fatalerror in case subdevice fails to find things (emu\addrmap.h)
    . Added ref count in flight calls and when a tap is installed (emu\emumem_heu.cpp), plus fix for less permissive compilers. Fixes segmentation fault in E-Swat (ID 07456).
  . LUA engine: Callback after sound update has generated new samples (mame\luaengine.cpp)
  . UI
    . Moved one variable down into subclasses and fixed some confusing variable naming
    . Fixed display of Covers tab in UI (ui\selmenu.cpp)
  . AVI
    . Added an image device to provide looping uncompressed AVI frames as input (imagedev\avivideo.cpp)
    . Fixed AVI framerate. MAME was setting up AVI before devices have properly launched, so default 60fps was used, which resulted in skipped frames in the video if machine's framerate is above 60 (btoads), and presumably duplicate frames for machines below 60fps (haven't tested). Now every frame that is generated is also present in the video.
    . Don't crash on buffer overflow and increased max AVI size (util\aviio.cpp)
  . 3rdparty
    . Sync GENie, BGFX, BX and BIMG with latest upstream. Added astc-codec decoder and NVN stub. Build BGFX as Objective-C++ on MacOS. Enabled Direct3D12 and Vulkan bgfx rendering backends. Added and building of spirv shaders. Do texture format conversion for BGFX via a full-screen GPU pass. Fixed BGFX build on older OS X systems. The Vulkan renderer has to be disabled on Yosemite and older because its backend depends on Metal.
    . Unbreak building shaders in cmd shell and add support for building them in MINGW bash shell (bgfx\scripts\tools.mk)
  . MiniMAWS
    . Load ROMs and disks and added a romident subcommand (scripts\minimaws\minimaws.py)
    . Added WEB interface for identifying ROM dumps. Chromium doesn't like in-place modification of returned JSON data.
    . Easier mod_wsgi deployment. Allow read-only database connections to be passed between threads
  . Get rid of sound start/reset overrides in machine configuration (emu\driver.cpp). Note: The various start/reset overrides are bugs waiting to happen. It's not immediately obvious that the ones run earlier can end up being called multiple times if subsequent ones throw missing dependencies exceptions. They're a relic of when everything from the old C-style drivers was thrown into classes all jumbled together.
  . Fixed flytiger entry in hiscore.dat (ID 07454)
- MAC OS X: Fixed build on Apple LLVM version 7.0.2 (clang-700.1.81). The same fix might also be needed for some non-Apple Clang versions.
- SDLMAME/Linux
  . Support RRGGBB00 format used by ARM Mali GPUs (render\drawsdl.cpp)
  . Check that m_display is not null to prevent crash. Fixes X11 Lightgun routine does not check for valid X11 display, resulting in crash (segmentation fault) (ID 07372)
  . Odroid N2 build fixes. Allow specifying NO_OPENGL manually. Switch bgfx to OpenGL ES renderer if NO_X11 is specified. Only link against EGL when NO_X11 is specified on linux, netbsd and openbsd. Only switch bgfx to OpenGL ES on linux, netbsd and openbsd. Indentation fix.
- Compiling
  . Build system maintenance
    . Re-write makedep.py for better performance and better parsing front-end
    . Make srcclean deal with kinds of preprocessor abuse I never want to see in real life
    . The new parser front-end is better at recognising C++ syntax and also substantially faster - bootstrapping a single-driver build should be noticeably quicker. Having a single parser for C++, .lst and .flt files also gets us a bit closer to making it simpler to create custom subtargets.
  . Make osd_printf_* use util/strformat semantics. Also removed a pile of redundant c_str and string_format, and some workarounds for not being able to portably format 64-bit integers or long long.
  . Allow updating version.cpp when IGNORE_GIT=1 is passed (makefile). Without this tweak it would only create the file if it doesn't exist, and wouldn't update an existing one.
  . Fixed a compilation bug under Clang-CL (netlist\plib\putil.h)
  . Fixed std::array initialisation with GCC5 in netlist\prg\nlwav.cpp, stop suppressing -Wterminate now that asserts are really asserts.
  . Visual Studio
    . Some Visual Studio 2019 fixes. Added initial ClangCL support. Fixed uwp builds' vs version typos. Added missing VS2019 toolchain.lua bits.
    . Use Visual Studio 2019 (16.3.0) image for AppVeyor build (appveyor.yml)
    . vs2019_clang builds and links with portaudio disabled
  . Removed all AM_ macro in comments
  . Clean up leftovers from MCFG removal
  . Added doxygen comments for a bunch of core stuff and converted a bunch of comments to doxygen format
  . Fixed build for nonstandard compiler versions like '8.3-win32' (scripts\genie.lua)
  . Continuous integration improvements: Added workaround for imgtool and jedutil failing vs2019 debug builds with /ZI. No longer allow msvc build to fail. Enabled tools build for travis to make it more useful. Switched travis to Xcode 11 in order to fix nltool linking failure. Prefer 64-bit compiler with VS 2019 too. Setting PreferredToolArchitecture to x64 is not needed, genie puts it into the project files for vs2015 or later. OPTIMIZE=1 build is faster that OPTIMIZE=0 for some reason. So fast in fact, that TOOLS=1 can be enabled without hitting the 60 minute timeout. Switched MINGW build to VS 2017 image until appveyor figure out why builds on VS 2019 are almost twice as slow. Run pacman twice to account for core system upgrades.
  . Reduced memory usage during compilation. Previous semantics were encouraged by sol2, and ThePhD admitted it was a bad idea for usertypes with lots of members. sol3 allows to assign members outside a constructor for regular usertypes, but MAME can't move to sol3 because it requires C++17. Turns out sol2 also has a way to add members separately, and that is what I used. This helps immensely. This approach required a fix to warning C5046 copied from here https://github.com/ThePhD/sol2/commit/57990845726e17fba11a39cfcb1fc0127a7ea638 . Tested current MAME plugins, everything seems to work. PS: Due to come black magic, if I use simple_usertype::set() with "manager" as well, "machine" member dies (others are fine!), so I had to leave it intact.
  . Fixed bimg build for asmjs and added bgfx file
