 # stixfonts
 OpenType Unicode fonts for Scientific, Technical, and Mathematical texts
 
-## Description
+## About the STIX fonts.
+
+See https://www.stixfonts.org/ for background on the the STIX Fonts project.
 
 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.
-
-See the [release notes](STIX_2.0.0_release_notes.txt) for a more
-detailed introduction to this version of the fonts.
-
-## Type 1 support
-
-The STIX Two fonts are a set of OpenType fonts and are meant to be
-used in that format.  For the benefit of LaTeX users who are currently
-unable to use XeTeX or LuaTeX, we have also provided a set of TFM, VF,
-and Type 1 files in the CTAN package stix2-type1.  Please note that
-while development of the OpenType fonts is ongoing, no further updates
-to the Type 1 versions are planned.

+professional publishing.  They are available royalty-free under the
+SIL Open Font License, Version 1.1.
+
+Version 2 of the STIX fonts, now known as “STIX Two”, is a thorough
+revision of version 1 undertaken by the renowned type house [Tiro
+Typeworks](https://tiro.com).  The STIX Two fonts consist of four text
+fonts (Regular, Italic, Bold, and Bold Italic) and one Math font.
+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](https://www.stixfonts.org/) began through the joint
+efforts of
+the [American Mathematical Society](https://www.ams.org/) (AMS),
+the [American Institute of Physics](https://www.aip.org/) (AIP),
+the [American Physical Society](https://www.aps.org/) (APS),
+the [American Chemical Society](https://www.acs.org/) (ACS),
+the [Institute of Electrical and Electronic](https://www.ieee.org/) Engineers (IEEE),
+and [Elsevier](https://www.elsevier.com/).
+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 as familiar to people who have only
+> known the common digital versions, while simultaneously restoring to
+> that typeface aspects of the size-appropriate design characteristics
+> that made it so successful in newspaper, book, and journal
+> publishing in it’s metal type incarnation. The essential
+> ‘Times-ness’ remains, but are with greater harmonisation of style
+> across the family.
+> 
+> “Most digital versions of Times have been based on an optical size
+> model that appears too light and fine when scaled down to typical
+> text sizes. In the design of STIX Two, we went back to specimens of
+> size-specific designs from the metal era, and adapted proportions,
+> weights, and spacing of the 10pt and 12pt designs. The oft-noted
+> mismatch between the style of different weights of Times has been
+> resolved with a new bold design that matches the construction of the
+> regular weight.”
+
+### Font implementation decisions
+
+* The STIX fonts do not contain fixed-width or sans serif text faces.
+
+* The sans serif, fraktur, script, etc., alphabets in Plane 1
+  (U+1D400-U+1D4FF) are intended to be used only as technical symbols.
+
+* These fonts are designed to support left-to-right typesetting in
+  Latin-based scripts, with additional support for Greek and Cyrillic
+  text.  Extensions to support other writing directions have been
+  considered, but are currently deemed to be outside the scope of the
+  STIX project.
+
+### Note to TeX users
+
+These fonts have been tested with both
+[XeTeX](http://xetex.sourceforge.net/)
+and
+[luaTeX](http://www.luatex.org/)
+with good results.  For best results, XeTeX users will want to use
+version 0.99999 or later of XeTeX, which ships with
+[TeXLive 2018](https://www.tug.org/texlive/).
+This version fixes a number of bugs that were present in earlier
+versions.  Our thanks go out to Jonathan Kew and Khaled Hosny for
+their generous help in identifying and fixing these bugs.  LaTeX users
+should also make sure they have the latest version of the
+[amsmath package](https://ctan.org/pkg/amsmath).

-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

-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.  The STIX Two fonts consist of four text fonts (Regular,
-Italic, Bold, and Bold Italic) and one Math font.  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 the fact that the
-Times was a very atypically produced newspaper: It was printed on very
-high quality paper run through presses that operated more slowly than
-most newspaper presses.  This allowed for the design of a typeface
-that could benefit from this level of printing: serifs could be very
-fine (much finer than other newspaper typefaces) and small counters
-(enclosed areas) such as in the lowercase e could be much smaller than
-in other newspaper typefaces.  Another anomaly is that the bold font
-for Times Roman 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)."
-
-WHAT IS NEW IN THIS RELEASE?
-
-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
-
-Full details of included glyphs and supported font features are
-available in the included spreadsheet.
-
-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.

-1.1", a copy of which is included in the License folder.
-
-Support for 8-bit, DVI-based TeX in the form of TFM files and Type 1
-fonts is available separately (see below).
-
-We also hope to provide a version of the WOFF fonts broken down into
-smaller, more web-download-friendly chunks.
-
-FONT IMPLEMENTATION DECISIONS
-
-The STIX fonts do not contain fixed-width or sans serif text faces.
-
-The sans serif, fraktur, script, etc., alphabets in Plane 1
-(U+1D400-U+1D4FF) are intended to be used only as technical symbols.
-
-These fonts are designed to support left-to-right typesetting in
-Latin-based scripts, with additional support for Greek and Cyrillic
-text.  Extensions to support other writing directions have been
-considered, but are currently deemed to be outside the scope of the
-STIX project.
-
-The font contains:
-
-1. Kerning pairs for characters suitable for use with sizes 8pt
-   through 12pt.
-
-2. Standard ligature support for those ligatures included in the font.
-
-NOTE TO TEX USERS
-
-If you use XeTeX or LuaTeX, the OTF files are all you need.  The fonts
-have been tested with both XeTeX and luaTeX with good results.  For
-best results, XeTeX users will want to upgrade to the latest
-development version from
-
-    http://xetex.sourceforge.net/
-
-This version fixes a number of bugs that are present in the version
-shipped with TeX Live 2016.  Our thanks go out to Jonathan Kew and
-Khaled Hosny for their generous help in identifying and fixing these
-bugs.  LaTeX users should also make sure they have the latest version
-of the amsmath package available on CTAN.
-
-There are some known issues with kerning of second-order subscripts
-that we hope to address in a future release.
-
-For the convenience of users who are restricted to pdfTeX or DVI-based
-TeX, a separate implementation set of Type 1 PostScript fonts, TFM
-files, and virtual fonts is available from
-
-    https://github.com/stipub/stixfonts/tree/master/STIXv2.0.0/Fonts/Type1
-
-Please note that although development work on the OpenType fonts is
-ongoing, no further updates are planned to the Type 1 fonts.
-
-FEEDBACK
-
-Please direct any questions or general comments to the STIX Fonts
-project.  Bug reports and technical support issues should be reported
-through https://github.com/stipub/stixfonts.

+
+                         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

+    
+
+                         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.
