  . Mitsubishi M37450
    . Restored M740 T flag correctly during PLP and RTI. Previous emulation inherited from the 6502 base device caused these instructions to always set T in P and not affect instruction decoding at all (m6502\dm740.lst, m740.h and om740.lst).
    . Changed many M740 instruction timings and dummy fetch patterns to match Mitsubishi documentation rather than 6502 behavior. Added overrides to be used for separable data space in future M50734 emulation. Fixed incorrect addition of Y to address of EORT $zp. Eliminated INCT A and DECT A instructions (T=1 has no effect on INC A or DEC A). Added STP and WIT instructions (not distinguished for now). Eliminated generic M740 device type (not used by anything) (m6502\dm740.lst, m740.cpp/h and om740.lst). NMI does not exist. Updated notes.

  . Floppy
    . Actually build the accepted variants list in floppy (imagedev\floppy.cpp). Provide the variants to the floppy formats. Updated floptool to the new prototypes (tools\floptool.cpp).
    . If an IMD image is 40 track but the drive is HD, put the data on even tracks like hardware would show. Use has_variant() and accept either HD or QD as 80-track drives (formats\imd_dsk.cpp).
    . Fixed precision issue and missing cache clear on write (imagedev\floppy.cpp)
    . Changed the extracted bitstreams into vector and the extracted sectors into vector>
    . When the floppy head stays on an unformatted track from more than an hour and ten minutes and reading happens then interval_index*2+1 overflows. Found and tracked down by Colin Howell, with much thanks (imagedev\floppy.cpp). as_ticks returns a u64, so go unsigned all the way (imagedev\floppy.cpp).

  . Improved service inputs for consistency with other drivers in jpmimpctsw.cpp. Promoted Roller Coaster and clones to working.
  . Started refactoring/researching more of JPM System 5 drivers (jpmsys5.cpp and jpmsys5sw.cpp). Various sets now proceed further in boot sequence, but still fail. Some additional elements (reel lamps, 7segs etc.) now have outputs so can be represented in fallback layout. Use recently added repeater feature of layouts in fallback layout* begin jpmsys5 refactoring.
  . jpmimpct.cpp/jpmimpctsw.cpp progress on non-video fruit machines: Hopper tweaks to allow many more sets to boot. Return 0xffff from some unknown memory addresses to allow later games to boot (security / anti-tamper?). Better per-game defaults to allow more sets to boot. Alt reel configs for a handful of ACE games to allow them to boot. Removed a few bad dumps. Correct ROM loading on several sets. Fixed up manufacturer information for several sets.

- MAME
  . VIDEO RENDERING SYSTEM
    . Use std::string_view instead of bare pointers in various functions (emu\rendlay.cpp)
    . Use std::fill instead of memset for dirty vector. Added range check (util\palette.cpp).
    . Dependency refactoring. Splitted out layout class declarations into rendlay.h, with some adjustments for the resulting incomplete types (std::reference_wrapper unfortunately does not allow these by C++17 rules) (emu\render.h). Moved old header contents to layout/generic.h (emu\rendlay.h).
    . BGFX: Added LCD-grid shader. Note that this is currently only compiled for GLSL. Fixed overlapping register in LCD-grid shaders and compiled for Direct3D, SPIR-V, Metal etc.
  . MEMORY SYSTEM
    . More idiomatic way to access members inherited from argument-dependent base templates (may or may not work around GCC11 bug) (emu\emumem_*.cpp)
    . Fixed some issue when the view does nor span an exact power-of-two block (emu\emumem_hedr.ipp and emumem_hedw.ipp)
  . OSD
    . Splitted out file, directory and path classes and methods to a new header (osdfile.h), Doxygenizing the documentation comments (osd\osdcore.h).
    . Centralized basic functions and de-virtualize various getters (osd\modules\osdwindow.cpp)
    . Fixed a couple of fixed-size buffers in Windows OSD code. Marked MAME as aware of long paths in Windows manifest. Made a cleaner, thread-safe API for getting volume names.
    . Minimised full-screen windows on losing focus (osd\windows\window.cpp). Clean up window title formatting. Show data type model in window title. Moved window title formatting to a single place (osd\modules\osdwindow.cpp). Rearranged window title to put system name first (modules\osdwindow.cpp).
    . Moved GCC intrinsics out of eminline.h so MAME_NOASM will take the pure C++ implementation with GCC (makes testing the fallback easier).
  . UI: Fixed use of strmakelower (ui\selsoft.cpp)
  . PLUGINS
    . Migrate remaining XML cheat code for Lua API changes (plugins\cheat\cheat_xml.lua). Fixes cheats show errors attempting to activate (ID 07830).
    . Use history.xml and added XML parser for it (plugins\xml\init.lua and plugin.json)
    . Removed logging and fixed query (plugins\data\data_history.lua)
    . Better hiscore parsing and other improvements (plugins\data\data_hiscore.lua)
  . Input port: Fixed a recent regression with processing XInput DPAD input item tokens. Prevent code_to_token from blowing up in strange cases (emu\input.cpp and inputdev.cpp).
  . Removed natkeyboard from ioport_manager (emu\ioport.cpp)
  . Changed string processing to use std::string_view parameters. Added sum16 type (lib\util\hash.cpp and hashing.cpp). Added -h option to print hashes and 16-bit sums for all files (tools\romcmp.cpp).
  . Make "slot" feature in software lists and a few related features case-sensitive
  . Simplified snapshot/quickload callback parameters. Removed some uses of auto_alloc_array (imagedev\snapquik.cpp).
  . Adopt std::string_view as the input parameter type for most functions (this necessitates some explicit copying to std::string since other APIs have not been updated yet). Remove zippath_parent_basename, whose implementation was utterly broken and fortunately unused. Fixed unintialized variable issue in zippath_resolve. Eliminated one internal helper function (util\zippath.cpp).
  . Documentation update: Added note explaining that view options saved in machine CFG take precedence over INI/command line. Added prerequisites for building HTML documentation under MSYS2 and Fedora Linux. Explicitly mentioned that Ubuntu modifies GCC to enable "fortify source" by default in the relevant section. Removed obsolete reference to glibstdc++6. Re-formated compiling guide source (hard wrap at 80 columns, typographical quotes, code blocks for sample command lines).
- Compiling
  . C++ comment conversion (util\xmlfile.cpp). Added get_attribute_string_ptr method that distinguishes between empty strings and absent attributes without falling back to C strings (util\xmlfile.cpp).
  . Eliminated redundant std::string("...").c_str() pattern (emu\ioport.cpp)
  . Initialized more pointers and variables (drivers\hitpoker.cpp and video\tlc34076.cpp). Fixes random chance of launching with missing colors in ghoshunt, mouseatk, tickee and tutstomb (ID 07833).
  . Changed puts to take a std::string_view parameter (util\corefile.cpp and emu\fileio.cpp)
  . Removed the using declaration importing util::string_format into the global namespace. It has been moved to emucore.h and a few tool sources. Other references have been qualified (util\strformat.h)
  . Disaggregate many #includes that were including other standard or custom headers. emu.h now includes basically the same things that it did, but other headers have been streamlined; for instance, emucore.h no longer stealth-includes osdcore.h several ways.
  . The string_format calls need qualification now (file\windir.cpp and winrtdir.cpp)
  . Purge #include "rendlay.h" where not necessary
  . Changed some unused functions to use [[maybe_unused]] attribute so they don't rot (audio/redbaron.h, drivers\deco_ld.cpp and pinball2k.cpp)
  . Disable MSVC windows CI, breaks for probably unfisable heap space issues (workflows\ci-windows.yml).
  . Fixed build on FreeBSD/powerpc64. FreeBSD uses powerpc64 name for what Linux calls ppc64.
  . Clean up inline maths utilities. Removed inline assembly for operations compilers handle well. Added ARM and AArch64 implementation for a few operations. Added unsigned integer add with carry out operations. Make preprocessor usage a bit more consistent in inline utilties for PPC/ARM.
  . Much more core std::string_view modernization: Removed corestr.h from emu.h; update a few source files to not use it at all. Changed strtrimspace, strtrimrightspace and core_filename_extract_* to be pure functions taking a std::string_view by value and returning the same type. Changed strmakeupper and strmakelower to be pure functions taking a std::string_view and constructing a std::string. Removed the string-modifying version of zippath_parent. Changed tag-based lookup functions in device_t to take std::string_view instead of const std::string & or const char*. Removed the subdevice tag cache from device_t (since device finders are now recommended) and replace it with a map covering directly owned subdevices only. Moved the working directory setup method out of device_image_interface (only the UI seems to actually use the full version of this). Change doutput_manager to use std::string_view for output name arguments. Changed core_options to accept std::string_view for most name and value arguments (return values are still C strings for now). Changed miscellaneous other functions to accept std::string_view arguments. Removed a few string accessor macros from romload.h. Removed many unnecessary c_str() calls from logging/error messages.
  . Removed some unnecessary .c_str() calls (tools\chdman.cpp)
  . C++17: Replaced ATTR_UNUSED with [[maybe_unused]]. Fixed for GCC build ("-Wno-error=attributes", -- GCC fails to recognize some uses of [[maybe_unused]]).

- MAME
  . VIDEO RENDERING SYSTEM
    . BGFX: Fixed failure to load texture .png files when -artpath contains multiple directories. Fixes BFGX Shadow Mask not appearing in slider controls when more than one artpath present in mame.ini (ID 06935). Use platform-specific path separator more consistently (render\bgfx\chainentryreader.cpp).
    . Fixed assertion failure in some GCC builds (util\palette.cpp)
    . Increased precision of ellipse calculations. Also optimised drawing fully covered ellipse pixels and added a few comments (emu\rendlay.cpp).
    . BGFX
      . CRT-Geom and CRT-Geom-Deluxe enhancements: Added a "brightness boost" feature for the shadow mask that works by making the brightness ratio between bright and dark mask pixels closer to 1 for the brighter parts of the image. Added clamping to zero so that underscanning produces a black border. Added a "raster bloom" effect to crt-geom-deluxe that makes the image grow slightly when the average brightness of the screen is high, mimicking a common defect in CRTs.

  . MEMORY SYSTEM
    . Fixed regions and shares on dynamically-installed device maps (emu\emumem*)
    . Disabled the unmap-value-in-device-map test for now (emu\emumem_aspace.cpp and emumem_mview.cpp)

    . Clean up slider callbacks. Removed now-unused slider ID macros/enums (ui\ui.h)
    . Improved messages displayed when files are missing. Only show things preventing launch in UI (not NO_DUMP, optional, etc.). Don't show details like file lengths and checksums in UI. Actually do system audit when launching from favourites. Log the more detailed summary at info level (ui\selgame.cpp, selmenu.cpp and selsoft.cpp).
    . Fixed exception in debug build when selecting machine category filter (ui\utils.cpp)
  . Input port
    . Prevent race condition between ui_input().pressed() and poll() (ui\inputmap.cpp)

  . Validity: Ensure validation of device tags in non-default slot options (emu\validity.cpp)
- VGM player: Added 32 new entries
- Compiling
  . Removed 64 suffix on the main executable. If you want to build 64-bit and 32-bit in the same tree without them stomping on each other, use SEPARATE_BIN=1 (you already need to do this for TOOLS=1 anyway). Updated GitHub CI for executable names, added ORM check to Linux builds.
  . Unbreak aarch64 and arm builds (makefile). Fixes compiler error on Raspberry Pi (ID 07860).
  . Declare intent when requesting virtual memory for NetBSD (lib\osdlib_unix.cpp).
  . Suggested changes to MacOS to build: Changes in macOS section regarding current build requirements. Added basic info for Apple Silicon to macOS build instructions (docs\source\initialsetup\compilingmame.rst).
  . Initialized some variables which were causing incorrect behaviours in DRVNOCLEAR builds
  . LLD (LLVM linker) seems to add a minimal symbol that the system libraries catch. Be smarter about ignoring that (osd\modules\diagnostics\diagnostics_win32.cpp).
  . Fixed issues detected by Coverity Static Analysis (software) (machine\i8271.cpp, video\snes_ppu.cpp, audio\rax.cpp, ui\custui.cpp, ui\confswitch.h, drivers\halleys.cpp, bfm_sc2.cpp, highvdeo.cpp, lordgun.cpp, midzeus.cpp (thegrid), sfcbox.cpp and tnzs.cpp (tnzs.cpp))
  . Removed references to non-existent headers and duplicate source file references (scripts\src\bus.lua, cpu.lua, emu.lua, netlist.lua, target\mame\arcade.lua and mess.lua)
  . Eliminated ARRAY_LENGTH template in favor of C++17's std::size
  . Moved definition of EQUIVALENT_ARRAY to coretmpl.h (osd\osdcomm.h)
  . Use STRUCT_MEMBER for save state registration (cpu\sharc\sharc.cpp, machine\gt64xxx.cpp, sound\ym2413.cpp, video\snes_ppu.cpp)
  . Use std::fill(_n) instead of memset (cpu\arm7\arm7.cpp, tms9900\tms9995.cpp, machine\pckeybrd.cpp and video\jangou_blitter.cpp)
  . Removed obsolete typedef (emu\emucore.h)
  . Used object finders for istrebiteli.cpp
  . Removed unneeded machine().root_device() calls (megatech.cpp, mrgame.cpp, stuntair.cpp and vegas.cpp)
- Debugger

  . Added context menu with Copy Visible and Paste commands to debug views to win32 debugger (debugger\win\debugviewinfo.cpp)
  . Qt debugger updates: Added context menu with Copy Visible and Paste commands to debug views. Made memory view last PC display a context menu item. Fixed crash on right-clicking a memory view showing something other than an address space. Improved scrolling behaviour in Qt debugger. Fixes disassembly view glitch on bottom line (ID 07795).
  . Fixed commas in dumpkbd output (emu\natkeyboard.cpp)
  . Fixed debugger problem when writing values into memory (MESS Myarc Geneve 9640) and added debugger method to TMS9995
  . Improved behaviour of bottom line in Qt and win32 debugger views. Ported memory tracking feature from Qt to win32 module.
  . Fixed build on GCC (tools\unidasm.cpp)
  . Updated state views when memory is modified through the debugger (since registers can be memory-mapped) (debug\debugcpu.cpp)
  . Stop converting debugger console commands to all lowercase before parsing them. Case insensitivity has been preserved for command names, CPU and region tags and certain symbolic parameters (as well as expressions, which were treated as case-insensitive in other contexts), but filenames and character constants are no longer automatically lowercased.
  . Removed some superfluous c_str() calls (debug\debugcmd.cpp and debugcon.cpp). Removed local member referencing debugger_cpu, which is accessed only rarely since the console now tracks the visible CPU (debug\debugcmd.cpp).
  . Added m68000 to debugger\debuggdbstub.cpp
  . Added CLS command to clear console buffer (debug\debugcmd.cpp)
