- CPU
  . AM9517A: Silence logging. Added EISA variant.
  . Hitachi FD1089 Encrypted CPUs: Minor changes to SEGA FD1089 keys to match the format of real ones, thanks to Ed Cross (afighter, afighterc, afighterd, afighterf, afighterg, afighterh, alexkidd1, aliensyn2, aliensyn3, aliensyn5, aliensynj, aliensynjo, aurail1, aurailj, defense, dunkshot, dunkshota, dunkshoto, enduror, enduror1, endurora, outrundxj, sdi, sdia, sdib, shangon1, shangon2, shangon3, sjryuko, sjryuko1, timescan1 and wb35).
  . Hitachi SH-2: Fixed interpreter for CPS3
  . Intel I8086: Fixed passing of opcode address to coprocessor
  . MC68307: More accurate emulation of internal priority interrupt controller
  . MC68340: Preliminary cleanups. 68340 Interrupt overhaul: Interrupts are now properly acknowledged and arbitrated (many remain unimplemented). Interrupts are no longer automatically cleared upon acknowledgment except for the Programmable Interrupt Timer. Timer unit clears COM and sets TC and TO in the status register on applicable conditions. Timer unit's confusion of IE0 (TC IRQ enable) with IE2 (TO IRQ enable) has been sorted out.
  . MCS-48: Fixed disassembly of short jump instructions located on page boundaries (mcs48\mcs48dsm.cpp)
  . MIPS-I
    . Fixed stupid tlb error
    . Fixed coprocessor exceptions: Set the coprocessor error number in the cause register. Corrected side-effect handling in address translation. Added logging for RISC/OS system calls.
    . Magic number removal and more logging. RX3230 SCSI DMA (machine\mips_rambo.cpp).
  . MIPS-III
    . Fixed fastram accesses and COP0 exception handling
    . Fixed block checksumming. Fixes IRIX installer hang on (MESS) ip225015 (mips\mips3drc.cpp).
    . Added minimal support for revealing the Secondary Cache Line size in the Status Register. Added debugger exception hook.
  . Z8 / Zilog Z8681: Rewrote timer emulation, including support for most TIN and TOUT modes. Handle more timer corner cases. Preliminary UART emulation. Added standard_irq_callback for the sake of debugging. Mask RP properly for debug register view. Splitted sio_tick into two functions.
  . Z8 / Zilog Z8682: Added Z8682 type with (fake) internal ROM; prevent timer from endlessly thrashing with a count of 1. Provide Z8 test ROM from Zilog application note. First 18 bytes of this (the interrupt/reset bootstrap) are identical to the previous hand-crafted binary.
- SOUND
  . CD Audio: m_sotc isn't implemented as bool (machine\t10mmc.h)
  . DCS Audio Denver: Fixed ram bank mapping in Denver DCS audio (audio\dcs.cpp)
  . Seta ST-0026 NiLe: Added save states support
  . Sound Blaster: DMA fixes for SB Pro and SB16 (isa\sblaster.cpp)
  . Taito Ensoniq Sound System: Eliminated set_input_line_vector (audio\taito_en.cpp)
  . YMF262 OPL3: Fixed save states
- DEVICE
  . 8/16-bit ISA bus
    . Preparation for supporting DACK handshake line
    . Modernized ISA device configuration: Configure spaces without using cpu_device. Removed NMI enable logic (the flag is usually a property of the bus controller, not the bus itself). Default many unnecessary 8253 and 8259 clocks. Note that with this change, ISA devices can no longer cause a NMI on the host CPU unless the IOCHCK callback is explicitly configured. Fixed custom space configuration.
  . 6522 VIA
    . Count negative PB6 pulses in T2 counter mode. Note: VIA interrupt remains disconnected in (MESS) tv950 due to CRTC-related problems. This is fairly likely to cause regressions in other drivers which may need explicit writes to PB6.
    . Fixed timing for shifting under control of system clock
  . ADC083x/ADC084x A/D Converter: Default input clocks
  . Bus Master IDE Controller: Another use for required_address_space (machine\idectrl.cpp)
  . CHDMAN: Fixed GDI 2048 extraction
  . Discrete Netlist
    . Fixed incorrect order of constructor parameters in netlist_mame_int_input_device (machine\netlist.h). Fixes audio in Mario Bros. and clones, probably others too (ID 07185). Improved readability (machine\netlist.cpp).
    . Added gitignore to lib\netlist. Also clean up doxygen genereated files in netlist makefile (netlist\build\makefile). Code maintenance and fixed "pure virtual call" error.
    . More C++ alignment. pstring now behaves like std::string. This change removes all string extensions like trim, rpad, left and right from pstring and replaces them by function templates. This aligns a lot better with the intentions of the standard library (machine\netlist.cpp, nl_base.cpp, nl_parser.cpp, plib\pfmtlog.cpp and nltool.cpp).
    . Rewrote and simplified tiny bits. Fixed inappropriate use of netlist_sig_t for non-boolean values (nld_7474.cpp, nld_7483.cpp, nld_7493.cpp, nlid_truthtable.h, nl_base.cpp/h and nl_config.h).
    . Added 7497 netlist device. The 7497 device should now work as described in the TI datasheet. This datasheet contains an internal schematic with details on gates and D flip-flops used [Couriersud]. Netlist WIP: 7474 and 7497 test driver.
    . Fixed TP1983 and 7497 and added 7497 DIP version. The schematic for the TP1983 contains an error. R19 is connected to GND. This will never work since when Q goes low, the reset pulse will dead lock Q to low. R19 needs to be connected to VCC (5V). This will generate the proper high-pass filtered pulse. Further fixes for the 7497 as well.
    . C++ and minor performance optimizations. Improved type safety on string->numeric conversions.
    . 5% performance improvement for Breakout [TTL] from a single device (devices\nld_82S16.cpp)
    . Moved mainclock code from nl_base into header of nlid_system. Also moved some simple functions from nl_base.cpp into header.
    . Improved dealing ownership in pstreams. Replaced ATTR_UNUSED by C++ template. Reenabled LOG_STATS. Added && and || operators to preprocessor expressions. Fixed logging during object construction. Improved type safety for parameters.
    . Replaced downcast with static_cast to avoid errors
    . Refactored netlist creation. This is an effort to separate netlist creation from netlist execution. The primary target is to avoid that code which will only run during execution is able to call setup code and thus create ugly hacks.
    . More run/setup separation. Still some distance ahead in properly separating execution and setup. Added NVCCBUILD support to netlist makefile. Also converted some by-ref calls to pass by value.
    . Removed const on return types and non-necessary ref-by. pstream and ppreprocessor (now a pistream) refactoring.
    . nlwav now also converts log files to VCD format. Please refer to nlwav --help for examples. There is also an example how to create multi-channel wav files.
    . Added comment processing to preprocessor. Comments are now processed in the preprocessor. Previously directives in multiline comments were processed.
    . Refactor code for better scalability and flexibility. These changes aim to remove some of the duplication of code in the various solvers. Tested with gcc-7 clang-8 and nvcc-9.2.
  . DS12885 RTC/NVRAM: Added device ds12885ext same as ds12885 but 256 bytes ram
  . Fixed-Frequency Monochrome Monitor
    . FixFreq code maintenance and added RGB channel functionality
    . Implemented sub-pixel horizontal resolution. This is not yet used and missing static initialization interface. Electron beams in CRTs are not discrete. They are continous on a scanline. This modification allows a higher horizontal resolution to better model "subpixel" timing.
    . Removed FIXFREQ MCFG macros. Internalized screen configuration.
  . Floppy: Added output callback for unit/drive select lines. This is intended for future use by machines in which the US/DS lines are neither directly connected to the drives nor wholly disconnected from them (machine\upd765.cpp).
  . Intel 8251 USART: Flag parity and framing errors in status register. Protect some members no longer subjected to hacky public use.
  . Intel 8253 PIT and Intel 8259 PIC: Default input clocks to zero
  . OKI MSM6253 A/D Converter: Removed MCFG macros and added DEVCB3 support
  . MC68681 DUART: Detect framing and parity errors, storing flags with FIFO characters.
  . Midway Custom: Make initial serial number random (machine\midwayic.cpp)
  . Motorola MC68901 MFP: Detect framing and parity errors and signal Rx error interrupt if enabled
  . National Semiconductor INS8250 UART
    . Detect framing and parity errors; allow side effects of reads to be disabled.
    . Allow writes to MSR with lower 4 bits zero to clear the associated interrupt. This is not confirmed behavior, but is logically consistent with nonzero bits causing interrupts when written.
  . Nintendo Custom: Don't use float on cycles_to_attotime (video\ppu2c0x.cpp)
  . SCSI CD-ROM and SCSI Hard Disk
    . Added the read TOC command and fixed inquiry (machine\nscsi_cd.cpp)
    . Corrected inquiry with missing lun behaviour. Return error on mode sense for unsupported page (machine\nscsi_cd.cpp).
    . Track the current block LBA on writes (machine\nscsi_hd.cpp). Stubs some mode pages: The mips systems complain if hard disks don't support these pages and allow mode select on some of them. Added stubs for some mode pages. Detect and report an error for unsupported pages. Accept and ignore mode select command (machine\nscsi_hd.cpp).
    . Return diagnostics (machine\nscsi_cd.cpp and nscsi_hd.cpp)
  . Sega 315-5313 Megadrive VDP: Restored additional Sega 315-5313 palette entries used by 32X
  . Serial interface
    . Actually check parity of received bytes in modes other than PARITY_NONE; fixed transmission of parity bit in PARITY_EVEN mode (emu\diserial.cpp).
    . Make is_receiver_register_full and is_transmit_register_empty const and inline
  . SMC91C9x Ethernet Controller: Refactor code. Added initial MAC filter and fixed multicast address filtering and WIP.
  . Western Digital WD33C9x SCSI: New NSCSI device for WD33C9x SCSI Controllers. Handle disconnect command properly. Fixes fatalerror in (MESS) ip225015 with new WD core. Fixed non-dma data retrieval.
  . Z80 SCC Channel: Don't spam interrupt state

- quizpun2.cpp: Removed bad EEPROM dumps from Quiz Punch and Quiz Punch II. Note: These dumps contain no valid or even interesting data; the data (once swapped) just counts up from 0180 to 01BF (Did an EEPROM programmer read back the commands by mistake?). At least quizpun2 can successfully reprogram the EEPROM if the data it fetches from there is invalid.

  . VIDEO RENDERING SYSTEM
    . Start cleaning up palette configuration: Basically, initialisers go in the constructor arguments, and things for setting format go in set_format. Initialisation patterns can be specified with an enum discriminator or with a FUNC and optionally a tag. Formats can be specified with an enum discriminator or a size and function pointer. You must always supply the number of entries when setting the format. When initislising with a paletter initialisation member, you can specify the entries and indirecte entries together. The palette_device now has a standard constructor, so use .set_entries if you are specifying entry count with no format/initialisation. Also killed an overload on delegates that wasn't being useful (emu\emupal.cpp).
    . Fixed palette regressions in dgpix.cpp, inufuku.cpp, mugsmash.cpp and playmark.cpp
    . Transposed transformation matrix to fix BGFX colors
  . DEVICE
    . Misc MCFG removal
    . Mark empty PLD dumps from protected devices as NO_DUMP (chry10, chrygld, crsbingo, iqpipe, jackie, jingbelli, kingdrbb, mastninj, polepos2bi, pool10e, pool10j, quiz211, quizvid, royalcrdp and suprmriobl)
    . Added object finder for address spaces (emu\devfind.cpp). The constructor and set_tag methods for required_address_space and optional_address_space work slightly differently from other finders in that they take the address space number as an extra argument. There is also an option to request a space having a specific data width, and validation checks this as well as the space number. There is also no (required|optional)_address_space_array, but that shouldn't really be necessary since devices shouldn't need large numbers of these finders.
  . UI
    . Removed irrelevant header
    . Eliminated qsort (ui\inputmap.cpp)
    . Improved search function (use algorithm derived from Jaro-Winkler similarity to match search strings)
    . UI cleanup: Fixed crash on builds with fewer than 16 drivers. Fixed "available" filter in internal UI. Get rid of some UI globals that shouldn't be global. Better encapsulation in UI. Clean up favourites manager - in particular kill hidden state and O(n) walks. This breaks adding systems/software to favourites from the main tab menu.
    . More UI stuff: Splitted up the different parts of ICO loading in the menus (locating files, scaling, drawing, etc.). Added icon support to software selection menu. Added support for more ICO file variants, including PNG-in-ICO (new DIB parser is overkill for ICO but I can factor it out for BMP loading at some point). Added favourites filter for software menus - includes software that's favourited on any system, so GBC includes DMG favourties and vice versa. Eliminated unnecessary member variables and O(n) walks in software selection menu. Made the menus' cached texture structures a bit more efficient.
    . Restored functionality of the "Add to Favorites" item on the main in-emulation menu (emu\softlist_dev.cpp and ui/inifile.cpp)
    . Make search apply to the filtered list in system/software selection menus, and cache stuff used for searching in software selection menu.
  . Eliminated custom_port_read and use ioport finders instead (cyclemb.cpp, dbz.cpp, dreamwld.cpp, fuukifg3.cpp, jaguar.cpp, midvunit.cpp, psikyo4.cpp and stadhero.cpp)
  . Eliminated space and mem_mask arguments from read/write handlers (machine\68307.cpp, 68340.cpp, 68340ser.cpp, mc2661.cpp, mc68681.cpp and scn2674)
  . Added device support to configure_scanline (machine\timer.h)
  . Case sensitivity training for INI: Further standardization of the formatting. Correct filtering instructions (docs\source\advanced\bgfx.rst, advanced\devicemap.rst, advanced\glsl.rst, advanced\hlsl.rst, advanced\multiconfig.rst, advanced\paths.rst, advanced\shiftertoggle.rst, commandline\commandline-all.rs, commandline\sdlconfig.rst, commandline\windowsconfig.rst and initialsetup\installingmame.rst). Make INI file loading examples match current behaviour at least (advanced\multiconfig.rst).
  . Added some example XSLTs that operate on -listxml output (scripts\xslt\list-bios.xslt, list-runnable-tree.xslt and list-runnable.xslt). Treat *.xslt as XML (tools\srcclean.cpp).
  . Make informational verbs a bit more consistent, reduce copy/pasted code, a slight performance improvement for reading localisation files, and more documentation clean-up/correction/clarification (commandline\commandline-all.rst, techspecs\layout_files.rst, frontend\mame\clifront.cpp, clifront.h and language.cpp). Major formatting update for command line options (commandline\commandline-all.rst). Better documentation for compiling on Windows (initialsetup\compilingmame.rst).
  . Device Network Interface: Always call send_complete_cb, even if no adapter is present (emu\dinetwork.cpp).
  . Apply -verbose after processing command-line options and after first pass over .ini files
  . Fixed assert in field_set_name if no field is configured. This should help catch instances where PORT_NAME is accidentally substituted for PORT_START (a frequent mistake of mine) (emu\ioport.h).
  . Removed address_space argument from read/write handlers (machine\bankdev.cpp; drivers\pengadvb.cpp and cedar_magnet.cpp)
  . Updated hiscore.dat set changes
- SDLMAME
  . Clean up sdl_sound a bit (sound\sdl_sound.cpp)
  . Workaround for Web Audio autoplay restrictions in Chrome 71 (sound\js_sound.js)
  . Fixed joystick initialization with Emscripten SDL (input\input_sdl.cpp)
  . Better Emscripten SDL fix (input\input_sdl.cpp)
  . Keep track of which SDL input subsystems were initialized (input\input_sdl.cpp)
- Compiling
  . Downscope (audio\sente6vb.h and includes\balsente.h)
  . Updated some documentation and get the MAME and legacy MESS pages more in sync (docs\man\mame.6, mess.6 and source\commandline\commandline-all.rst)
  . Removed irrelevant header (drivers\sbowling.cpp)
  . Fixed non-trivial templates in emu\devdelegate.h for MSVC
  . Fixed a few missing #includes flagged by VS2019 beta (lib\util\timeconv.h and bgfx\effect.h)
  . Fixed errors with single-driver build of vsnes.cpp (scripts\genie.lua and src\main.lua)
  . Additional documentation on compiling MAME (docs\source\initialsetup\compilingmame.rst and osd\sdl_cfg.lua)
  . Reduced logging spam (sound\ymz280b.cpp and drivers\bfm_sc4.cpp)
  . Fixed SUBTARGET=nl build (netlist code; scripts\target\mame\nl.lua and mame\nl.lst)

- Debugger
  . Send logerror to stderr if no debugger is attached and -oslog is on (osd\windows\winmain.cpp and winutf8.cpp)
  . Don't blow up when TMS34010 disassembler tries to read 32-bit operands (tools\unidasm.cpp)

- CPU
  . Intel I80186: Make DRQ level triggered
  . Intel I386: Added comments about Athlon memory type range register MSRs (i386\cpuidmsrs.hxx)
  . Motorola MC68000: Added overrideable method to signal RESET instruction to internal peripherals (m68000\m68000.h, machine\68340.cpp). Added m68k_reset_peripherals() call to the non-generated file (m68000\m68k_in.cpp)
  . MIPS-III
    . Experimental R4000 implementation. Tweak address calculation. Added the ability to CTC and CFC from unknown fpr30, which IRIX does often. Added a primitive MRU scheme for tlb searches, resulting in an average of ~1.5 iterations per scan and 2-3% speedup in one test case. Also removed the confusing reverse-endian logic from lwl/lwr and friends because apparently no commercial software implementation has ever used it (and wasn't supported in any of the other instructions anyway). Paranoid approach for 64-bit mode check. Sign extension bugs. Signed multiply bug. Fixed ABS.S and ABS.D. Fixes X server crashing in IRIX.
    . Use the new 64x64 multiply helpers. Make sure unordered exceptions are generated by abs.fmt. Corrected an unimportant drc flag (mips\mips3.cpp and mips3fe.cpp).
  . RCA CDP1802: Don't skip over instructions in debugger after DMA cycles. This does nothing to fix MT#7232 (Unable to successfully boot a cartridge game (MESS) RCA Studio II), but could make the problem easier to debug.
  . Texas Instruments TMS9995: Fixed double-triggered INT1/4 by clearing the INT1/4 latch
  . Texas Instruments TMS34010: Internalized I/O register. Removed register_postload. Added notes.
- SOUND
  . AY8930 EPSG: Added notes for AY8930 expanded mode. Added mode register for debugging. Additional logs.
  . Ensoniq 5505/5506 to 5510 interface: Use required_device for m_esp. Added device_clock_changed. Added notes. Changed timer frequency related to sample rate(clock).
  . Ensoniq ES5506: Sync sample rate with sound\esqpump.cpp
  . ICS2115: Removed unnecessary arguments in handler. Moved igs011.cpp exclusive 16bit handlers into ics2115.cpp. Minor code style fixes. Use shorter type values. Correct device name. Minor code style fixes.
  . Excellent Systems ES8712 Sound Controller: Allow finder for MSM5205 (sound\es8712.h)
  . QS1000: Added getter for internal CPU
- DEVICE
  . 8042 Keyboard/Mouse Controller: Added timer to periodically check mouse. Fixes mouse in (MESS) SGI Indigo2/Indy IRIX.
  . Discrete Netlist
    . Refactoring and some innovations. Still some work ahead to separate interface from execution. This is a preparation to switch to another sparse matrix format easily which may be better suited for parallel processing. On the linear algebra side there are some nice additions: Two additional sort modes: One tries to obtain a upper left identity matrix, the other prefers a diagonal band matrix structure. Both deliver slightly better performance than just sorting. Parallel execution analysis for Gaussian elimination and LU solve. This determines which operations may be done independently. All of this is not really useful right now. The matrix sizes are below 100 nets. I estimate that we at least need four times more so that CPU parallel processing overhead pays off. For GPU, add another order. But it's nice to have code which may scale.
    . Code maintenance and fixing Kid Niki to run at acceptable speed again. Removed trampoline code.
    . All devices now specify parameters in factory constructor. This previously was part of net_lib.cpp and repeatedly caused bugs.
    . Refactoring and some functionality enhancements. Removed dead code. nltool now adds a define NLTOOL_VERSION. This can be tested in netlists. It is used in kidniki to ensure I stop committing debug parameters. Optimized the proposal for no-deactivate hints. Documented in breakout that hints were manually optimized. Minor optimizations in the order of 2% enhancement.
    . Aligned solver calls (netlist\devices\nld_4066.cpp, nld_4316.cpp, nld_mm5837.cpp, nld_schmitt.cpp, nld_system.cpp and nlid_proxy.cpp)
    . Optionally store input values instead of referencing them. Useful for debugging purposes in the end - but not performance. Store input values in logic_terminal_t: Set to 1 to store values in logic_terminal_t instead of accessing them indirectly by pointer from logic_net_t. This approach is stricter and should identify bugs in the netlist core faster. By default it is disabled since it is not as fast as the default approach.
    . Refactoring after adding Clang-tidy support to netlist makefile: Converted macros to C++ code. Order of device creation should not depend on std lib. Some state saving cleanup. Added support for Clang-tidy to makefile. Modifications triggered by Clang-tidy-9.
    . More CPP core guidelines work. Make constants struct members constexpr const. Enabled GCC diagnostics in vector ops for GCC 7 again. Use forwarding in vector_ops.
    . Added parameter STARTUP_STRATEGY to switch between startup strategies. This determines the order of device triggering: 0: Full - trigger all delegates. Next all devices not touched, 1: Backwards - trigger all devices backwards (only update delegate) and 2: Forward - trigger all devices forward (only update delegate).
    . Fixed crashes on certain hardware/library combos. At least on MacOSX memory used by an object seems to be invalidated before the dtor is executed. This of course is deadly for child objects with references to the parent-in-deletion which may call back into the parent. One of the worst issues I had to fix. Ever. Lesson learnt: No tricks in dtors. Never.
    . Indentation cleanup (plib\palloc.h). Memory allocation clean-up.
    . Memory pool now supports aligned storage. Set USE_MEMPOOL to 1 to try this (max 5% performance increase). For mingw, there is no alignment support. This triggers -Wattribute errors which due to -Werror crash the build.
    . Separation of duties. Make it clearer what is used during parsing a netlist, "compiling" a netlist and execution of a netlist.
    . Refactoring startup process and array usage. Removed locked-in context from sources.
  . INS8154 RAM I/O: Fixed bit register accesses
  . MC6850 ACIA: Allow disabling side effects for reads. Simplified read/write handlers.
  . Sega 315-5124 SMS1 VDP: Implemented internal PSG. Use shorter type values. Removed register_postload and unnecessary arguments in handlers.
  . Signetics SCN2674 AVDC
    . Row buffering and timing improvements. Added optional read callbacks for row buffering DMA. Added MBC output.
    . Corrected timing of BREQ and VBLANK outputs. Improved character blink and cursor blink timings.
    . Fixed line counter desyncing in (MESS) PCX video (video\scn2674.cpp). Blank display line by line.
  . SMC91C94 Ethernet Controller: Pull sticky stringstream settings out of loop
  . TI TLC34076 VIP: Removed unnecessary address_space arguments
  . Timer: Refactor IRQ timers (machine\timer.h)
  . Voltage Regulator: Output of 32768 is above MAME's sound stream cutoff (-32768 to 32767) (sound\volt_reg.h). Set default m_output.
  . Western Digital WD33C93B SCSI Controller: Silence logging by default (machine\wd33c9x.cpp)
  . Z8 / Zilog Z8681: Fixed disassembly of LD IR, R opcode. Write RRn instead of Rn when disassembling INCW/DECW (z8\z8dasm.cpp).

- MAME
  . VIDEO RENDERING SYSTEM
    . Added constructor for monochrom screens and removed MCFG_SCREEN_ADD_MONOCHROME and MCFG_SCREEN_COLOR (emu\screen.h)
    . Additive oversleeping for video throttling (emu\video.cpp)
    . Stop frameskipping constantly on screenless systems with frameskip=0 and don't use iter count (emu\video.cpp)
  . DEVICE
    . Misc MACHINE_CONFIG removal
    . Removed unnecessary address_space arguments on FM sound chips read/write handlers. Removed unnecessary arguments in handlers. Get rid of some copy/pasted macros for different numbers of arguments.
    . Added spacenum getter for required_/optional_address_space (emu\devfind.h)
    . Simplified read/write handlers (kingobox.cpp, videopin.cpp, machine\mos6551.cpp, machine\6821pia.cpp, machine\6840ptm.cpp, machine\6850acia.cpp, video\crtc_ega.cpp, video\mc6845.cpp and sound\votrax.cpp)
    . Use shorter/correct type values. Removed unnecessary arguments in handlers (sound\ay8910.cpp).
  . MEMORY SYSTEM: Eliminated the default address map member of address_space_config. Since all device address maps are now class methods defined in ordinary C++, default RAM maps can be provided more simply with an explicit has_configured_map check in an internal map definition. A number of default address maps that probably weren't meant to be overridden have also been changed to ordinary internal maps.
  . UI: Fixed crash when exiting directly while filter UI is active (ui\menu.cpp)
  . PLUGINS
    . Fixed address step when shift is negative (plugins\cheatfind\init.lua)
    . Cheat Finder Usability Improvements (plugins\cheatfind\init.lua): 1. Changed visual indications to make it nicer & quicker to use. 2. Added selectable automatic pause capability to the cheat finder menu. 3. Allows the Test/Write poke to be changed. 4. Added another cheat format capability for cheat.simple (write support only).
    . hiscore.dat update (plugins\hiscore\hiscore.dat). Added start delay and use emu.time (plugins\hiscore\init.lua).
    . Added history command (plugins\console\init.lua and 3rdparty\lua-linenoise\linenoise.c)
  . Updated commandline\commandline-all.rst and initialsetup\compilingmame.rst docs
  . Initial implementation of new logo for docs (images\MAMElogo.svg). Added svg->pdf conversion support (docs\source\conf.py).
  . Snapshot/Quickload
    . Enabled sub-second snapshot timers. Switch to attotime and accept doubles (imagedev\snapquik.cpp)
    . Make the delay for snapshot/quickload an attotime and allow implicit zero. Removing the MCFG macros properly requires changing the pattern for the delegates.
  . Multi-Language: Updated Brazilian Portuguese translations (better description of what MAME is really doing)
  . Fixed XML file structure for files in HASH folder which required it (hash\neogeo.xml...). Loadflag no longer required for jpond (ID 07231; hash\megadriv.xml). Srcclean the softlists.
- SDLMAME
  . Fixed SDL2 keymap processing. Keymaps must have been broken for ages: It is now possible to map every scancode SDL2 defines. Removed keycode field. This was a leftover from SDL1.x. Fixed bug preventing keymaps from working. Fixed the DE keymap. Converted other keymaps to new format and added a comment that they have to be reviewed and fixed.
  . Show video-mode option 'accel' in help and GUI (sdl\sdlmain.cpp)
  . Added SDL testkeys as a tool again. Attempt to fix testkeys linking in more configurations. Testkeys: Clean up and modernise code. Use std::endl to end lines for its implicit flush. Centre window (less likely to hide behind taskbar, etc.). OSDWin: Ensure new windows are positioned within the work area of a monitor (windows\video.h and window.cpp).
  . Use lowercase for some libraries that are lowercase in System32 on Windows anyway. Make USE_BUNDLED_LIB_SDL2=0 not use the bundled SDL (osd/sdl.lua and tools.lua).
- Compiling
  . Support LLVM extension in MSVC (make vsllvm) using extension from here: https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.llvm-toolchain
  . Fixed 3rdparty/ASIO to compile with libc++ 9.0 (asio\detail\config.hpp)
  . Added 64x64 multiply helpers (osd\eivcx86.h and eminline.h). Added GCC/Clang implementations of 64*64->128 multiply for x86_64 and adjust some integer casts (osd\eigccx86.h and eminline.h).
  . Fixed cross compile MAME/SDL/Windows
  . Use OVERRIDE_CC if defined to determine GCC_VERSION. Fixes some cross-compilation issues and most likely edge case using OVERRIDE_CC (makefile).
  . Removed some superfluous const, a superfluous temp, superflous semicolons, etc. and also fixed a known broken build script change.
  . Documented cross-compilation options
- Debugger: Eliminated qsort usage in debugger (debug\debugcmd.cpp, dvbpoints.cpp/h and dvwpoints.cpp/h)
