include/freetype/cache/ftcmru.h, include/freetype/cache/ftcglyph.h, src/cache/ftcbasic.c, src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcmanag.c: additional speed optimization to the cache sub-system. It is now up to 70% faster than the one in the previous table release (i.e. 2.1.7). Note that the API did slightly change though.
