This release fixes a glitch in the OS/2 tables: Bit 8 (WWS) of the fsSelection field has been set and the OS/2 table version has been updated to 4. No changes were made to any glyphs or metrics. WHAT'S NEW IN 2.0.1? COMPATIBILITY BETWEEN 2.0.1 AND 2.0.0 There have been numerous improvements to the design of individual glyphs and to the placement of various accents. Since these don't affect character metrics, they should not affect the layout of documents that used v2.0.0 of the fonts. Users upgrading existing documents from 2.0.0 to 2.0.1 should be aware of the following potential incompatibilities: * Character metrics for some glyphs, especially Mathematical Alphanumeric Symbols and APL functional symbols, have changed. * Kerning between z and following punctuation has been improved. * In STIX2Math, Stylistic Set 7 (ss07) no longer includes U+2205 * U+2202 PARTIAL DIFFERENTIAL and U+1D6DB MATHEMATICAL BOLD PARTIAL DIFFERENTIAL are now upright by default. See below for further details. TEXT FONTS * Added U+2423 OPEN BOX to all faces. * Added Stylistic Set ss02 to select upright parentheses, brackets, and braces in Italic and BoldItalic faces. * Harmonized design of smallcap U+02A9 LATIN SMALL LETTER FENG DIGRAPH between Regular and Bold faces. * Improved design of extended Latin and IPA character glyphs. * Improved kerning of selected character pairs. * Improved design and placement of U+0307 COMBINING DOT ABOVE and U+0308 COMBINING DIAERESIS. MATH FONTS * The following Mathematical Alphanumeric Symbols have been improved. Note that in some case this has necessitated changes to the character metrics. U+1D504..1D537 Fraktur symbols U+1D538..1D56B Double-struck symbols U+1D56C..1D59F Bold Fraktur symbols U+1D5A0..1D5D3 Sans-serif symbols [SSP] U+1D5D4..1D607 Sans-serif bold symbols [SSP] U+1D608..1D63B Sans-serif italic symbols [SSP] U+1D63C..1D66F Sans-serif bold italic symbols [SSP] U+1D670..1D6A3 Monospace symbols U+1D756..1D78F Sans-serif bold Greek U+1D790..1D7C9 Sans-serif bold italic Greek U+1D7D8..1D7E1 Double-struck digits U+1D7E2..1D7EB Sans-serif digits [SSP] U+1D7EC..1D7F5 Sans-serif bold digits [SSP] U+1D7F6..1D7FF Monospace digits Note: The ranges marked "[SSP]" are derived from the Source Sans Pro fonts, with proportions and weight modified to harmonize with the STIX design. * Added support for Unicode Standard Mathematical Standardized Variants. * Removed variant form of U+2205 EMPTY SET from Stylistic Set 7 to Character Variant 3. NOTE: For most users, the "variant" form will be the preferred shape, but the default shape has been left as-is for backwards compatibility. * Improved proportions of existing APL symbols and added an additional 16 symbols (see below). * Corrected glyph for U+1D752 MATHEMATICAL BOLD ITALIC KAPPA SYMBOL. * Improved positioning of tilde math accent. * Added dotless variants of U+2148 DOUBLE-STRUCK ITALIC SMALL I and U_2149 DOUBLE-STRUCK ITALIC SMALL J. * Made U+2202 PARTIAL DIFFERENTIAL and U+1D6DB MATHEMATICAL BOLD PARTIAL DIFFERENTIAL upright rather than italic. * Revised and extended coverage of Enclosed Alphanumeric block (U+2460-24FF). * U+20E1 COMBINING LEFT RIGHT ARROW ABOVE is now extensible. * Corrected vertical placement of U+00B1 PLUS-MINUS SIGN * The following delimiters now have a full set of 12 growing form variants.

There are no plans to include further support for Arabic typesetting. WHAT'S NEW IN 2.0.0? In addition to the overall visual redesign, STIX Two incorporates a number of significant improvements and additions. Special attention has been given to implementing accepted best practices for OpenType fonts, such as the use of font features to access variant glyph shapes that were previously only available via the Unicode Private Use Areas. The letterspacing and kerning of the text fonts have been significantly improved. True small capital variants (Latin, Cyrillic, and Greek), accessible via the OpenType font feature smcp, have been added for all text fonts. Text (lowercase or oldstyle) numerals, available via the font features pnum and onum, have been added, in addition to natural-spacing figures. Alphabetic superscripts and numeric sub- and superscripts, accessible via the subs and sups font features, have been added. Fractions are available via the frac feature, as well as numerators (numr) and denominators (dnom). The OpenType MATH table has been completely rewritten and extended. Additions have been made to these Unicode blocks: Latin-1 Supplement U+0080 - U+00FF Latin Extended-A U+0100 - U+017F Latin Extended Additional U+0180 - U+024F Cyrillic U+0400 - U+04FF Greek and Coptic U+0370 - U+03FF IPA blocks U+0250 - U+02AF BACKWARDS COMPATIBILITY Because of the scope of the changes, especially to the text fonts, STIX Two is not a drop-in replacement for earlier versions. While we understand and sympathize with the difficulties caused by the incompatibilities we have introduced, we nevertheless felt they were necessary to address some of the shortcomings of earlier versions of the fonts and to position us to respond to the needs of modern publishing. Earlier versions of the STIX fonts are deprecated and no longer supported. We urge all users of the STIX fonts to upgrade to the new versions as soon as possible. To enable the new and old versions of the fonts to coexist during the transition phase, the fonts have been renamed as follows: STIX 1.1.0 STIX 2.0.0 STIX-Regular STIX Two Text STIX-Italic STIX Two Text Italic STIX-Bold STIX Two Text Bold STIX-BoldItalic STIX Two Text Bold Italic STIX Math Regular STIX Two Math The four text fonts contain glyphs from Unicode text blocks only. For example, all characters from the range U+2190 to U+3063 and U+E000 to U+E368 and all plane 1 characters have been removed from the text fonts and are now found only in STIX Two Math. Whenever possible, characters have been removed from the Private Use Area (U+E000-U+F8FF) and made available via font features instead. The STIX-General packaging of the fonts is no longer supported.
