FreeType, a popular font rendering engine, has reached the 2.7 release with a new default mode for bytecode hinting: Subpixel hinting.
In case you are already using subpixel hinting (for example, by using the ‘Infinality patches’ as provided by some GNU/Linux or BSD distributions, or directly from bohoomil.com), be noted that the new mode might provide subtle differences; the code was simplified to make it much faster. If you are used to the old full-pixel hinting, you will see many rendering changes. If you really dislike them, you can disable them at compile time or using the new FREETYPE_PROPERTIES environment variable.
The new release also has improvements to its smooth rasterizer to make it about 20% faster, fixes to fuzzer, handling of raw CID fonts, and various other bug fixes and improvements. See details at FreeType.org.
