From karl at freefriends.org Sat Jan 21 23:52:15 2023 From: karl at freefriends.org (Karl Berry) Date: Sat, 21 Jan 2023 15:52:15 -0700 Subject: [lucida] lucida-1.901 (2023-01-21) available Message-ID: <202301212252.30LMqFi5029562@freefriends.org> A new version (1.901) of the Lucida OpenType fonts from TUG is available. As with previous updates, there's no additional charge if you've already purchased licenses; you can use the same download information sent to you at the time of purchase to get the new fonts. (If you've lost the download info, you can email us at lucida-admin at tug.org.) I will append the changes for this release. The same information is also online at https://tug.org/store/lucida/NEWS.txt. To summarize, the most significant changes have been to the math fonts, especially the regular-weight LucidaBrightMathOT. Many of these changes were discussed in greater detail in the recent article about Lucida math by Hans Hagen and Mikael Sundqvist: https://tug.org/TUGboat/tb43-3/tb135hagen-lucida.pdf The four Lucida Sans fonts and the three specialized fonts (Blackletter, Calligraphy, Handwriting) are not changed at all from the last release (not even version numbers or dates). All other fonts were changed. On behalf of TUG, I thank Hans, Mikael, and Michael Sharpe, who among them did essentially all of the technical font editing for this release. And we must thank Chuck Bigelow and Kris Holmes (they approved this release, as always), without whom nothing could be done. Bug reports and character/feature requests are welcome (email to this list is best), though, as usual, we cannot promise any particular timeline for the next release. Happy typesetting, Karl TUG Lucida home page: https://tug.org/lucida ----------------------------------------------------------------------------- - LucidaBrightMathOT (regular) changes, along with whether the change was also made in LucidaBrightMathOT-Demi (bold): . math axis changed! For the rationale and examples of this (and several of the other) change(s), see the article by Hans Hagen and Mikael Sundqvist, Patching Lucida Bright Math: https://tug.org/TUGboat/tb43-3/tb135hagen-lucida.pdf. The previous value was 313; now it is 325, which is the correct value for most of the symbols intended to be aligned on the axis; other symbols, including parentheses, integrals, etc., had to be raised to match the new value. This will change most nontrivial math typesetting, but in a small way, and hopefully for the better. (Also done in bold math.) . widths of math relational and binary operators, notably including < and >, corrected to have a consistent width. Also, for the ss03 stylistic set (small/Type 1 operator size), width of = corrected. Again this will affect much math, hopefully for the better. Original report: https://tug.org/pipermail/lucida/2022-March/000864.html (Also done in bold math.) . added smaller versions of characters in Geometric Shapes (U+25A0...) block. Activated with ss03, same as the smaller math operators, matching the Type 1 sizes. (Not done in bold math.) . added characters U+027EA and U+027EB (left/right double angle bracket), \lAngle and \rAngle in unicode-math. (Not done in bold math.) . added character U+034D (combining left-right arrow below), \underleftrightarrow in unicode-math. (Not done in bold math.) . added characters U+2661 U+2662 U+2664 U+2667, the white card suits (hearts, diamonds, spades, clubs, in character order). This makes all eight suit commands defined in unicode-math work: \spadesuit..\clubsuit and \varspadesuit..\varclubsuit. Before, only the filled suits were available. (Also done in bold math.) . added character U+29E0 (the d'Alembertian operator), \laplac in unicode-math. A variant glyph design, closer to the U+2206 Laplace operator, is used if new feature ss08 is specified. (Also done in bold math.) . ellipsis characters (U+2026, U+22EF, others) switched to use the same dot as the normal punctuation period, and slightly widened. (Not done in bold math.) . geometric shapes (U+25A1..25FF) given a consistent line thickness. (Not done in bold math.) . for \sqrt (U+221A) constructions, fix small misalignment of overline with radical diagonal. Original report: https://chat.stackexchange.com/transcript/message/61527262 (Partially done in bold math.) . general cleanup of extensible recipes, including parentheses and braces, both vertical and horizontal, integrals, and others. (Not done in bold math.) . make sizes of \uparrow (U+2191) and \downarrow (U+2193) the same, and a little shorter. Original report: https://tug.org/pipermail/lucida/2022-August/000910.html (Not done in bold math.) . regularize ovals of \oiint (U+222F) and \oiiint (U+2230). (Not done in bold math.) - Changes in LucidaBrightMathOT-Demi only: . horizontal ellipsis (U+2026) added. . copyright symbol (U+00A9) dimensions adjusted to match regular math. . integral signs and delimiters made more consistent, and a bit bolder. - All monospaced fonts have the isFixedPitch attribute manually set to 1, to work around a bug in fontforge. Recent macOS versions look for this attribute to find monospaced fonts in the Font Book application. Twelve fonts affected (four fonts in each of three families): .

Original report: https://tug.org/pipermail/lucida/2022-August/000897.html - LucidaBrightOT-Demi: . base character of smallcaps c-cedilla is now the smallcaps `c' instead of the regular lowercase `c'. Original report: https://tex.stackexchange.com/questions/575868 . hinting removed. - LucidaBrightOT-DemiItalic, LucidaConsoleDK-Italic: hinting also removed. These fonts were the only ones remaining with hint instructions; we missed them in our general hint removal in version 1.801 (which was released 13 March 2016). - All *.fontspec files now use the Extension specifier, to work around a bug in fontspec 2.8a (and possibly other versions).
