Ver 2.609: 31.03.2026
* collective release of AP, LM, TG; missing version number added -- the same for all fonts of the TG collection

Ver 2.003: 16.09.2009
* this is the first official release of the TeX Gyre Chorus font since
  June 22, 2009, when URW++, represented by Dr. Peter Rosenfeld, its
  Managing Director, kindly agreed to release the original 35 base
  PostScript fonts as shipped with Ghostscript ver. 4.00 under the LPPL
  (LaTeX Project Public License). This should be understood so that the
  35 base Postscript fonts may be used and developed either under the
  LPPL or one of the GPL (GNU Public Licence) or AFPL (Aladdin Free
  Public Licence). The latter were put in force with the initial release
  of the base fonts with Ghostscript ver. 4.00 in 1996. Hereby we thank
  Dr. Rosenfeld. The TeX Gyre fonts are being develped from the
  Ghostscript ver. 4.00 base. For reasons explained elsewhere, we prefer
  to provide our work under the GUST Font Licence (GFL) which is legally
  equivallent to the LPPL. However, since 1996 the 35 PostScript base
  fonts were enhanced under the GNU Public License with Vietnamese glyphs
  by Han The Thanh and Cyrillic glyphs by Valek Filippov. Han The Thanh
  kindly permitted his additions to be retained under under GFL/LPPL in
  this and future TeX Gyre fonts releases. Unfortunately, we were unable
  to receive a similar permission from Valek Filippov for his Cyrillic
  glyphs, thus there are no Cyrillic glyphs in any of the TeX Gyre fonts.
* with the removal of the Cyrillic glyphs all t2a-*.tfm, t2b-*.tfm
  t2c-*.tfm files and the relevant LaTeX *.fd files were also removed.
* typos in ligature schemes in `comm_mph.mp' corrected
  (`quotedblbase' and `quotedblleft' instead `quotedblright')
* paragraph.alt made different from paragraph
* a few glyphs corrected: corrected A, dotlessi, ff, f_k, fl, ffl, fi, ffi;
  apart from A, dotlessi, fi and fl -- widths changed:
    wd._ff=640  -> wd._ff=552
    wd._ffi=840 -> wd._ffi=752
    wd._ffl=840 -> wd._ffl=752
    wd._f_k=760 -> wd._f_k=700
* spaceskip make consistent with the width of space --
  0.22em plus 0.11em minus 0.073em;  thanks to Jarmo Niemel\"a
  for pointing out the problem;
  previous spacing (0.333em  plus 0.167em minus 0.111em) can be restored:
  (a) in plain -- by setting \spaceskip=0.333em plus 0.167em minus 0.111em
  (b) in LaTeX -- by using option `oldspacing'
* OTF structure corrected and improved (in particular, the ligature ffi
  works now properly)
* `visiblespace' renamed to `uni2423' (suggestion of Werner Lemberg and
  Karl Berry) -- hopefully everywhere...
* `Dblgravecomb' renamed to `dblGravecomb'
* `nomero'  in MT1 sources renamed to `numero', shape altered,
  name `afii61352' no more used
* undertie added (suggestion of Werner Lemberg)
  U+203F -- undertie (smile-shaped glyph placed below baseline)
  U+2040 -- tie (frown-shaped glyph placed at the top line)
  U+2054 -- undertieinverted (frown-shaped glyph placed below baseline)
  nota bene, there is no code point in the Unicode table for the inverted tie...
* glyphs `acaron', `Acaron', `icaron', `Icaron', `idieresisacute',
  `Idieresisacute', `jcaron', `J_caron', `ocaron', `Ocaron', `ucaron',
  `Ucaron', `udieresisacute', `Udieresisacute', `udieresiscaron',
  `Udieresiscaron', `udieresisgrave', and `Udieresisgrave' added
  (proposal of Oliver Corff) -- all the glyphs but `J_caron' have code
  points in the Unicode table and names assigned in the Adobe Glyph List
  (incidentaly, in J_caron apostrophe is used alike in lcaron and tcaron --
  cf. http://en.wikipedia.org/wiki/J-caron)
* glyps orogate and Orogate (`rogate' in Polish means `with horns')
  added -- they are used to denote nasal vowels in ancient Polish texts
  (ca. XIV century)
* uni2010 (hyphen duplicate) i uni2011 (non-breakable hyphen duplicate) added
  (suggestion of Hans Hagen)
* LaTeX *.sty and *.fd files reworked:
  -- option `oldspacing' provided because of the change of default spacing
     (see above),
  -- files l7x*.fd (Lithuanian) refer to `L7x', as they should,
  -- scheme of referring to slanted variants improved,
  -- option `scaled=<size>' added which allows to rescale font
     at loading,
  -- in TeX Gyre LaTeX packages, text bold is defined as
     \renewcommand\bfdefault{b} (`b' instead of `bx')
  -- options `matchlowercase'/`matchuppercase' added which scale
     the font such that its `x_height'/`cap_height' matches
     the respective dimension of the main font of the document;
     one can say also, e.g., `matchlowercase=1.1' if scaling to 110%
     of the `x_height' of the main font of the document is needed;
     sample usage:
       \documentclass{article}
       \usepackage[T1]{fontenc}
       \usepackage[matchlowercase]{tgtermes,tgadventor,tgheros}
       \begin{document}
         We put TG Termes (main) with \textsf{TG Heros} and
         {\fontfamily{qag}\selectfont TG Adventor}. \textsf{As~a~result},
         all small letters have the same heights.
       \end{document}
  (note that now TeX Gyre LaTeX styles require the `kvoptions' module
  which, in turn, necessitates using etex)
  very many thanks to Marcin Woli\'nski

REMARKS:
* we are not going to introduce any extensions that would result
  in yet more TFMs files (e.g., for more convenient handling
  of oldstyle/normal digits) -- in such cases we suggest using
  the OTF fonts versions
* improving hints is a kind of Sisyphean job -- there are no tools
  for automatic hinting checking; the only method is to check
  optically/manually each and every character with various display
  agents, on various screens under various operating systems and various
  resolutions. We are not totally opposing Sisyphean jobs in general,
  but having had that much time as we had, we decided to spend it on
  other improvements...

Ver. 1.103: 22.02.2008
* math glyphs shifted horizontally (widths left intact)
* in the OTF files, the features `salt', `ss01', `ss02',
  `ss03', `ss04' added

Ver. 1.102: 19.02.2008 -- inofficial release
* compatibility with the recent Latin Modern release (1.106) implemented,
  see -- http://www.gust.org.pl/projects/e-foundry/latin-modern/
  main changes: the repertoire of glyphs extended by Arabic transliteration
  glyphs, OTF structure modified (`size' feature implemented, the ligatures
  `i_j' and `I_J' available only for Dutch, the ligature `f_k' -- for Polish,
  the `locl' feature reimplemented -- an artificial glyph `i.TRK' is no
  longer needed)
* glyphs uni03C6 and uni03D5 used to be interchanged in all TeX Gyre fonts;
  the unicode specification is not explicit too much:
    03C6;GREEK SMALL LETTER PHI
    03D5;GREEK PHI SYMBOL
  but FileFormat.Info is:
    http://www.fileformat.info/info/unicode/char/03c6/index.htm
    http://www.fileformat.info/info/unicode/char/03d5/index.htm
  (spotted by Michael Zedler, thanks)

Ver. 1.099: 30.01.2008 -- unpublished
* `copyright.alt' added
* a peculiar ligature `lslash_lslash' added (in the Private Unicode Area,
  of course, uniEC0F); in TeX, it is available for the following encodings:
  CS (Czech, q-cszc.enc), L7x (Lithuanian, q-l7xzc.enc), LY1 (Y&Y aka
  TeX'n'ANSI, q-texnansizc.enc), QX (Polish, q-qxzc.enc),
  RM (math); in all the encodings but the last one the ligature
  `lslash_lslash' replaced the `currency' glyph (nearly useless),
  in the RM encoding -- `periodcentered'; in OTF files, it is created out
  of two subsequent lslashes for all scripts and all languages whenever
  the feature `liga' is activated

Ver. 1.000, 25.09.2007:
* the first release
  NOTE: the widths of the TeX Gyre Chorus glyphs are almost consistent
  with the relevant Adobe metric data (for the glyphs from the Adobe
  Standard Encoding):
    ftp://ftp.adobe.com/pub/adobe/type/win/all/afmfiles/base35/zcmi____.afm
  except `grave' and `questiondown' (Adobe 220 and 400, Tex Gyre 300 and 380,
  respectively).
