Build 468:
  UI DRB: (Windows) Reworked DPI awareness code to:
        a) prevent glitching when changing DPI levels during dragging of the window between monitors with different DPI settings,
        b) prevent too high zoom levels that make the game not fit on the screen,
        c) prevent the DPI state from getting out of sync with the window dimensions, which resulted in mouse inputs being scaled incorrectly.
  UI DRB: (Windows) You can now increase/decrease the DPI scale with ctrl+/- (the win/loss cheat is now moved to ctrl+cmd +/-)
  OT ALS: Fixed issue where "Heroes of Co-op B12" would always get selected as a mapset, if found. Note: Plugins with a -1 checksum are now disallowed.
  FX DRB: Fixed graphical issue with units getting incorrect team colors after loading a coop savegame.
  FX DRB: Optimized loading of high res sprites (~30% speedup)

  GP MRM: The gameplay version reported to the metaserver when a network game starts will now be accurate.
  GP ALS+MRM: Patch 1.8.5 Unity is now loaded conditionally based on a list of plugins that are known to support it correctly. The plugins are:

Build 466:
  FX MRM: Finished and enabled dynamic sprite shadow generation. Enable by using the setting "Detail Shadows" on the preferences screen.
  UI MRM: Added an option on the Controls screen for "Alternate Unit Selection". This option changes when band selection is possible so that you can only begin a band selection when:
          1. You have no controllable units selected.

          3. You hold down Alt or Command to remove units from your selection.
  OT MRM: Allow players to join themselves to create a team where they are the first member.
  FX MRM: Adding a new option for how sprites are colorized that takes into account the original saturation of the colors. Things like specular highlights will be better preserved using this method.

  OT MRM: Fixed an issue where coop games on a metaserver that were loaded from a save could not be joined when in-progress.
  UI MRM: Fixed an issue that caused films of coop games loaded from a saved game to not show the player list in the Saved Films dialog.

  OT MRM: Fixed bug in DX11 texture cache that could cause out of bounds memory access.
  OT DRB: If there is more than one recommended display device, show it as "most recommended" in the preferences.
  OT DRB: (Windows) On Windows 10 and above, prefer DX11 over OpenGL.
  OT DRB: (Windows) Added [Renderer.OpenGL] WindowedFullscreenBehavior poweruser.txt preference. Enabled by default. This is a workaround for aggressive presentation mode optimizations that break windowed fullscreen mode under OpenGL. See "INI file readme.html" for details.
  OT DRB: (Windows) Disable DPI scaling on legacy rasterizers (3Dfx, old Direct3D)
  OT DRB: (Windows) Prevent the Myth window from getting resized too small during in-progress resolution changes when the operating system reports a desktop work area that is smaller than our window.
  OT DRB: (Windows) Under old D3D, hide screen resolutions with widths that are not multiples of 32 since these don't work correctly (status bars look corrupted/glitchy).
  FX MRM: Fixed an issue when rendering detail collections which replace collections with mirrored frames in sequences.
  FX DRB: (OpenGL) Fixed a minor texture coordinate distortion effect that could happen when sprites get clipped, e.g. by having feet underwater.

    - Gonen's Bridge is now beatable.

  OT MRM: Fixed a bug causing the game to lock up when a sound device was lost.
  GP ALS: Fixed an issue where a spawned monster that's set to detonate immediately may respawn using marker 0 (fixes an assert on Lichen MWC2020 in Deathmatch).
