+
+Basic Font Information
+----------------------
+
+INTRODUCTION
+
+The Scientific and Technical Information eXchange (STIX) fonts are
+intended to satisfy the demanding needs of authors, publishers,
+printers, and others working in the scientific, medical, and technical
+fields. They combine a comprehensive Unicode-based collection of
+mathematical symbols and alphabets with a set of text faces suitable
+for professional publishing. The fonts are available royalty-free
+under the SIL Open Font License.
+
+Version 2.0.0 of the STIX fonts, now known as "STIX Two", is a
+thorough revision undertaken by the renowned type house Tiro Typeworks
+Ltd. (https://www.tiro.com). The STIX Two fonts consist of one Math
+font, two variable text fonts (STIXTwoTextVF-Roman and
+STIXTwoTextVF-Italic), and eight static text fonts (Regular, Italic,
+Medium, Medium Italic, SemiBold, SemiBold Italic, Bold, and Bold
+Italic) derived from the variable fonts. Together, they provide a
+uniform set of fonts that can be used throughout the production
+process, whether that be a traditional print-only process, an entirely
+electronic one, or a combination of the two.
+
+The STIX project began through the joint efforts of American
+Mathematical Society (AMS), American Institute of Physics (AIP),
+American Physical Society (APS), American Chemical Society (ACS),
+Institute of Electrical and Electronic Engineers (IEEE), and Elsevier.
+These companies are collectively known as the STI Pub companies.
+
+A FRESH TAKE ON TIMES ROMAN
+
+The original version of STIX was based on Times Roman, which has now
+been updated for the digital age.
+
+As is well known, Times Roman was originally intended for printing the
+London Times. What is not generally appreciated is that the
+production quality of the *Times* was atypically high: It was printed
+on unusually high-quality paper on presses that operated more slowly
+than most newspaper presses. This allowed for the design of a
+typeface that could exploit this level of care: serifs could be much
+finer and counters (enclosed areas such as that in the lowercase e)
+could be much smaller than in other newspaper typefaces. These
+features of the font have not always fared well in less exacting
+environments. At the same time, a notable quirk of the Times Roman
+family is that the bold font is, in many respects, strikingly
+dissimilar to the roman font.
+
+Tiro Typeworks explain their approach to updating the Times Roman
+basis of STIX as follows:
+
+ "Our principal goal in approaching STIX Two was to address several
+ inherent deficiencies in the Times New Roman model as well as
+ expand the typographic features. This process necessarily
+ involved diverging somewhat from Times, given that many features
+ of that typeface are either incompatible with current printing
+ methods and electronic reading environments, and some others too
+ esoteric to repeat. That said, the essential 'Times-ness'
+ remains, we believe, and such changes won't distract readers and
+ users in any negative way.
+
+ "At the core of Times' problems was inappropriate digitization,
+ using an optical size model too large to be scaled down to text
+ sizes, with compensations appropriate to its original purpose and
+ printing technique, but not for 21st century conditions. We have
+ also re-thought somewhat overall proportions and spacing, with
+ changes made in varying degrees to both the Roman and the Italic
+ (and we have begun to harmonize the Bold, which has always been a
+ major shortcoming with Times New Roman)."
+
+ChangeLog
+---------
+
+13 January 2021, STIX Two, version 2.11
+
+* Changed "Semibold" to "SemiBold" in all font and file names.
+
+* Fixed various technical issues required for compatibility with the
+ Google Fonts platform. There were no changes to font metrics or
+ glyph shapes.
+
+-----------------------------------
+
+18 December 2020, STIX Two, version 2.10
+
+For compatibility with the internal major/minor versioning convention
+used by the OpenType font format, the public version number was
+switched from the three-part semantic versioning convention to a
+two-part number.
+
+All non-variable fonts are now available in both OTF and TTF formats.
+
+The WOFF format is no longer distributed.
+
+COMPATIBILITY BETWEEN 2.0.2 AND 2.10
+
+There have been extensive changes to both glyph shapes and font
+metrics in this release. These could affect the layout of documents
+prepared with previous versions of these fonts.
+
+UPDATES TO MATH AND TEXT FONTS
+
+The following changes apply to both the text and math fonts:
+
+* Removed the Macintosh platform entries from the name table as they
+ are now considered obsolete.
+
+* Completed U+2100..214F Letterlike Symbols by adding
+
+ U+2100 ACCOUNT OF

+
+UPDATES TO TEXT FONTS
+
+* 2.10 includes OpenType variable font builds for the Text fonts
+ (STIXTwoTextVF-Roman.ttf and STIXTwoTextVF-Italic.ttf). For more
+ information about variable fonts see:
+
+ https://medium.com/variable-fonts/https-medium-com-tiro-introducing-opentype-variable-fonts-12ba6cd2369
+
+ The STIX Two Text variable fonts support a weight interpolation axis
+ between the regular and bold weights, with named instances for
+ medium and semibold. New static fonts for these instances are
+ derived from the variable fonts. Development of the variable fonts
+ was funded by Google Fonts.
+
+* New static weights: Medium and Semibold
+
+* Add anchor mark-to-base and mark-to-mark positioning for Unicode
+ combining mark characters, to provide positioning for arbitrary
+ diacritic marks
+
+UPDATES TO MATH FONT

+ Mapped existing roundhand glyphs to Stylistic Set 1 (ss01).
+
+* Added bold chancery script characters (U+1D4D0..U+1D503), also

+* Refined/replaced existing roundhand script style variant glyphs,
+ presuming that these may be preferred by some users to the new
+ chancery default.
+
+* Extended set of 'ssty' super- and subscript scaling variants.

+-----------------------------------
+
+18 June 2019, STIX Two, version 2.0.2
+
+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.
+
+-----------------------------------
+
+15 April 2019, STIX Two, version 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.
+

+1 December 2016, STIX Two, version 2.0.0
+
+In addition to the overall visual redesign, STIX Two incorporates a
+number of significant improvements and additions over version 1 of the
+fonts. 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.
