The DVI id have been bumped to - 6 to reflect this. -* XeTeX now looks for the xdvipdfmx binary installed next to it and no longer - requires that it is installed in the system PATH (this was previously done - only on Windows). - -============================================================== -XeTeX 0.99991 was released 20140614 - -* Drop build date from “--version” output. -* Drop Mac-specific image loading code, as it makes little sense after we - dropped xdv2pdf. Supported image formats are the same on all platforms now. -* Fix OpenType math cut-ins support which was not always working properly. -* Avoid Unicode compatibility decomposition fallback for characters not - supported by the font as it often result in loss of essential characteristics - (like using regular Latin characters in place of missing math fraktur ones). - Non compatibility decomposition and composition fallback is still supported. -* For hybrid OpenType/Graphite fonts, we now prefer using OpenType for - compatibility with pre-0.9999 XeTeX. -* Fix many memory leaks when using AAT fonts on Mac. -* The “language” font option when loading Graphite fonts in now treated as a - BCP 47 language tag not and OpenType one. -* Various Unicode fixes for Windows console (thanks to TANAKA Takuji). -* Respect vertical glyph positioning with AAT fonts (fixes, for example, - rendering of the new Arabic fonts in Mac OS X 10.9). - -============================================================== -XeTeX 0.9999.3 was released 20130528 - -* Fix bug with extensible accents resulting in invalid glyph id some times. -* Fix alternate index in multiple alternates features to be start from zero - like pre-0.9999 XeTeX. -* Document multiple alternates syntax in the reference documentation. - -============================================================== -XeTeX 0.9999.2 was released 20130406 - -* Fix regression in \XeTeXOT* primitives with fonts where the number of - languages in a given script is not the same in both GSUB and GPOS tables. - -* Add a workaround for a bug in clang headers to allow building with it on Mac. - -* Fix regression in loading PNG files on Mac. - -* Fix multiple regression with vertical text layout. - -* Update to HarfBuzz 0.9.15 fixing a couple of regressions with Arabic non - spacing marks and Hangul jamo. - -* Various build fixes for third party libraries. - -* XeTeX reference is now included in the release tarball. - -xdvipdfmx: -* Speed up inclusion of eps figures by Tsuchimura Nobuyuki. - -============================================================== -XeTeX 0.9999.1 was released 20130322 - -* Fix loading font files on PPC Mac OS 10.5 (and potentially other versions of - Mac). - -* Fix handling of ‘script’ and ‘language’ font options to be treated again as - OpenType not ISO tags, so that passing version 2 Indic script tags works - (though this is generally not needed as HarfBuzz will always use version 2 - shaping if the font has it, regardless of the tag used). - -* Fix loading JPEG images that do not specify a resolution. - -* When printing multi-byte characters to log or terminal avoid inserting new - lines in the middle of the characters, and count the characters not the bytes - when calculating line length. - -* Update to HarfBuzz 0.9.14, a couple of Indic and Hangul shaping bugs. - -xdvipdfmx: -* Speed up calculating glyph widths in native font. - -* Don’t crash when /tmp is full. - -============================================================== -XeTeX 0.9999.0 was released 20130311 - -* Port OpenType layout from ICU LayoutEngine to HarfBuzz. - HarfBuzz is actively maintained and generally have much wider support for - OpenType spec, the switch fixes a number of OpenType bugs: - - Support version 2 OpenType Indic specs. - - Many other Indic OpenType bugs, and support for the latest additions to - OpenType spec. - - Incorrect application of contextual features. - - Incorrect kerning in fonts that has both old “kern” table and new GPOS - “kern” feature. - - Allow suppressing Latin ligatures with ZWNJ. - - Support for variation selectors. - - Support for user-specified features with complex scripts. - -* Port Graphite layout to from SilGraphite to HarfBuzz and Graphite2. Which - provides a more robust Graphite support and also fixes a number of Graphite - bugs. - -* Port AAT font layout and font searching on Mac from the deprecated ATS/ATSUI - to Core Text, and image support on Mac from QuickTime to ImageIO framework. - XeTeX can be finally built on 64-bit Mac! Work contributed by Jiang Jiang. - -* Add “/OT” font variant, similar to “/ICU” which is now deprecated. - -* Add a “shaper” font option to specify HarfBuzz shapers (for testing). - -* Guess script from input string if no one is given in the font definition, - instead of defaulting to Latin. - -* Support 4-letter tags for Graphite features. - -* Fix applying negative delta glyph advance to the last glyph in the run, fixes - issues with “halt” and “vhal” features. - -* Use \U prefix for extended math primitives, allowing XeTeX and LuaTeX to use - the same names for Unicode math primitives supported by both engines. The old - \XeTeX* primitives have been deprecated and will be removed in the future. - -* Support OpenType math cut ins. - -* Fix “\show” and “\meaning” of “\Umathchar” to a print a form that is legal - input. - -* Fix italic correction to not depend on space factor being zero for OpenType - fonts. - -* Fix sporadic shifting of extensible accents. - -* Fix typesetting XeTeX’s WEB code, in addition to various slight improvements. - -* Prefer TrueType/OpenType over Type1 fonts with the same font name. - -* Support input pipes, in line with other engines. - -* Drop support for using “()” as font names quotes since it was causing file - names with parenthesis not to be found. - -* Fix “\show” with characters outside BMP. - -* Print the actual character instead of hex code for characters outside BMP - with “\show”, “\meaning”, “\showlists” and missing char log messages. - -* Fix letterspacing if zero width glyphs. - -* Try to get cap and x height from OS/2 table first. - -* Reject bitmap only fonts. - -* Include build date in “--version” output. - -============================================================== -XeTeX 0.9998 was released 20120708 - -* Fix mismatch between fonts loaded by XeTeX and xdvipdfmx when multiple - versions of the font exist. - -* Fix “\the\textfont” with families > 15 - -* Extend “\fam” to accept family number up to 255. - -* Fix build on Mac OS 10.7 - -OpenType math: - -* Fix displacement of big operator's limits when “DisplayOperatorMinHeight” is - higher than the size of the big operator. - -* Fix too wide accents over accentees that has sub/superscript. - -* Support extensible accents for “\overbrace” etc. - -* Always take math constants from current font, fixes multiple math discrepancies. - -* Honor relevant math constants when positioning sub/superscripts. - -* Honor “AccentBaseHeight” when placing accents. - -* Support “fixed” and “bottom” keywords in “\XeTeXmathaccent” for non growing - and bottom accents, respectively. - -* Fix horizontal placement of of accents over single letters to honor their top - accent position value. - -* Fix vertical placement of sub/superscripts of single letters to not be - treated as non-single letters. - -* Support proper positioning of nested accents. |
