Important and Urgent (0.55.1)

• Release 0.55.1:
  • 0.55.1 pre-release thread (stuff to do to be shipped in the release) #3165

Important and Urgent (0.56.0)

• Merge as much as possible gameplay things from @cu-kai and @sweet235 servers, to be detailed.
• game: Vampire mode #3292

Important but not Urgent

• engine+game: Inefficient IPC calls #3157
• data: Replace the Tremulous sound files
  This is among project's goals since 11 years, we are 11 years late.

Fancy

• engine: Finish the PBR texture mapping
  Not fixing this prevents us to recruit texture artists, and makes us unable to use actual texture libraries like https://ambientcg.com/ , https://cc0-textures.com/ , https://publicdomaintextures.com/ and others.

• engine: Finish reflection cubemaps

• engine: Fix or reimplement the dynamic shadows
  This is a regression, even Quake 3 had them 25 years ago.

• engine: Finish correct lighting linear colorspace lightmap applied on non-linear sRGB colorspace diffusemap DaemonEngine/Daemon#270
  We already done a lot of goodness with complete overbright, but we need to push the engine further to be be considered a contemporary engine, games are condemned to only look like good-looking games from the 90's.

• game: Impact on movable surface
  A game not doing that looks very primitive, some other games implemented that 20 years ago!

• engine: Fix water code water shader is broken DaemonEngine/Daemon#645 Investigating the non-working liquid shader DaemonEngine/Daemon#850
  This is a regression, XreaL had it. Other engines like DarkPlaces have it. Without that, games are condemned to look like games from the 90's.
