ELFBSP v1.3.0

Changes since ELFBSP 1.2

New features:

• Added support for the new XBM1 32-bit blockmap lump format
  • Instead of outputting empty BLOCKMAP lumps when the vanilla format overflows, it will output XBM1 lumps
• Changed default BSP tree lump format in Doom & Hexen map formats to XNOD, this will help massively reduce slime trails
• Restored support for compressed variants of ZDBSP formats (ZNOD, ZGLN, ZGL2, ZGL3)
  • ZGL3 is now the default for UDMF levels
  • The new --compress CLI flag will force the use of the compressed counterparts in the Doom & Hexen map formats
• Improved blockmap compression for smaller lump size
  • Added automatic removal of non-special self-referencing linedefs from the blockmap
  • Revised "identical blocklist deduplication" algorithm, now cuts down a few more blocks
  • Added "Blocklist size sorting" to squeeze out smaller offsets
  • Added --bmap-zero CLI flag for vanilla-optimized blockmaps
• Added support for the Doom 64 binary map format, and its LEAFS lump
  • Includes the DeePBSPV4 BSP tree lump format for large maps exceeding the vanilla limits
  • Includes the XBM1 blockmap lump format for large maps exceeding the vanilla limits
• Added support for proper REJECT building algorithm with visibility checks (thanks @knightmb)
  • Using --fast makes the builder skip the visibility algorithm, and uses only the sector grouping algorithm
• Added support for special effects in Doom 64 map format levels
  • Sector special of 999 is blocked from the REJECT grouping algorithm, makes enemies within it "blind"
  • Lines containing the "Do not add to blockmap" linedef flag will be excluded from the blockmap
  • Lines containing both the "Show on automap" AND "Hide from automap" linedef flags will be excluded the blockmap
• Added UDMF namespace awareness for polyobjects, DoomEdNums are now inferred automtically from the namespace
  • Hexen polyobject editor numbers for the Hexen and DelphiHexen namespaces
  • ZDoom polyobject editor numbers for all other namespaces
  • The --polyobj CLI flag is now ignored for UDMF maps
• Added simple performance profiler on CLI output, benchmarking the time taken by certain parts of the builder to work
• Added --skip-bsp, --skip-bmap and --skip-reject CLI flags to skip building maps that are already compiled

Bugfixes:

• Restored REJECT builder's debug logging, i.e fix --debug-reject not working before
• Fixed critical UDMF reading issues
  • Fixed map format detection loading UDMF levels as Hexen map format levels
  • Fixed long-standing borked UDMF lump parsing

Meta:

• Removed support for Intel MacOS, only ARM MacOS (Apple Silicon) is now supported
• Fixed builds not being static, should now run on UDB Flatpak just fine
• Windows builds now use MSYS2 Clang instead of MSYS2 MinGW
• Added Linux GCC to CI pipeline
