2 * Iterative cluster fit is now considered to be a new compression mode
3 * The core cluster fit is now 4x faster using contributions by Ignacio
5 * The single colour lookup table has been halved by exploiting symmetry
8 * Added contributed SSE1 truncate implementation
9 * Changed use of SQUISH_USE_SSE to be 1 for SSE and 2 for SSE2 instructions
10 * Cluster fit is now iterative to further reduce image error
13 * Switched from using floor to trunc for much better SSE performance (again)
14 * Xcode build now expects libpng in /usr/local for extra/squishpng
17 * Fixed floating-point equality issue in clusterfit sort (x86 affected only)
18 * Implemented proper SSE(2) floor function for 50% speedup on SSE builds
19 * The range fit implementation now uses the correct colour metric
22 * Fixed bug in CompressImage where masked pixels were not skipped over
23 * DXT3 and DXT5 alpha compression now properly use the mask to ignore pixels
24 * Fixed major DXT1 bug that can generate unexpected transparent pixels
27 * Added CompressMasked function to handle incomplete DXT blocks more cleanly
28 * Added kWeightColourByAlpha flag for better quality images when alpha blending
31 * Fixed stack overflow in rangefit
34 * Worked around SSE floor implementation bug, proper fix needed!
35 * This release has visual studio and makefile builds that work
38 * Added provably optimal single colour compressor
39 * Added extra/squishgen.cpp that generates single colour lookup tables
42 * Fixed a DXT1 colour output bug
43 * Changed argument order for Decompress function to match Compress
44 * Added GetStorageRequirements function
45 * Added CompressImage function
46 * Added DecompressImage function
47 * Moved squishtool.cpp to extra/squishpng.cpp
48 * Added extra/squishtest.cpp
