Differences

Multithreaded LZMA compression
- Threads can be adjusted with "-threads N" parameter
.mp3, .wav, .ani and .vcs (shaders) files are no longer compressed
- This prevents caching bugs in the engine
- See this page for more info
Supports maps that exceed soft limits such as overlays, lights and entities
Supports shared LDR/HDR data from VRAD++
- This prevents map sizes from inflating after packing content
Supports Garry's Mod
- GMod's BSPZIP does not support compression (even though GMod's engine can load compressed maps)
- Now you can use BSPZIP++ to compress maps for GMod
Supports SDK2013 Singleplayer BSPs
- Note that compression is NOT supported on the singleplayer engine
Added -verbose flag for more detailed information

Supported games

BSPZIP++ is currently available for all games on Team Fortress 2 branch and Garry's Mod.
