dc-chg.txt
This file documents the changes on the dc-fonts since version 1.1. Most
recent changes are on top of this file.
1-FEB-1997 After the release of the ec fonts, this file is closed.
Further changes will be documented in ec-chg.txt.
19-JAN-1997 Fought again with the |uc_hachek_accent| since it came out too
high (with white space above) in the metrics. Eliminated
|uc_acc_height#| from exrueast.mf and the driver files.
Fixed a bug in the single base quote (reported by Bernd Raichle)
Added anti-kernings to separate ```triple''' and
````quadruple'''' quotes nicely
ectc: Call exmligtb for monospace ligatures
Did some finish to the ligtables (this is the last chance, in
fact, since changing the ligtables changes the metrics).
7-JAN-1997 Added ecfs (Fibonacci Slanted) as suggested by Ulrik Vieth
Changed |vair| for ecso from 13 to 15 (found by Ulrik Vieth)
Corrected Batch file generation in ecstdedt.tex
Deleted dxbase.ini_mf (suggested by Ulrik Vieth)
23-DEC-1996 Made all fontnames 4 letters + 4 digits for the interpolating
fonts. Renamed ecr -> ecrm, ecb -> ecrb, ecu -> ecui.
22-DEC-1996 Accents for small capital letters are now ``small capital
accents''. Moved information from exaccess to exbase.
Made capital tilde accent 9u# wide. Reincluded
|center_on| in exbase. Deleted all references to dcbase.
Consequently applied |hi.| in expseudo.mf. Improved the
|uc_hachek_accent| on small caps.
Added typewriter fonts (both visible and invisible) for
documentclass slides (former SliTeX), named [i]ecltt8.
ecltt8 is unfortunately different from ectt0800, because the
interpolation routines introduce some rounding errors on
the base points.
21-DEC-1996 Deleted boolean variable |acute_sharp| from exbase, because
it was never used. Added switch |fancy_thorn| to choose
different thorn shapes.
20-DEC-1996 Starting transition to ec: Renamed files, replaced
|dcchar| by |ecchar|, renamed |font_identifier|, changed
file headers, changed |version_check| to ask for (1,0).
19-NOV-1996 Removed |big_...|-macros from dxbase. Added macro
|super_crescent| used in the Servicemark sign.
18-NOV-1996 Adjusted parameters in dcbi (there was an awful bug
in |jut| causing no error messages but damaged
glyphs with dcbi0500)
18-NOV-1996 Added more ligtable entries: Kv (Kvarner) Kw (Kwik),
V against consonants (russian transliteration)
4-NOV-1996 Adjusted the position of the circumflex in \^a. Also made
all lowercase circumflexes overshoot a little (oo).
*********** Release of dc 1.3 Patchlevel 4 *************************************
25-AUG-1996 Aplied the parameter change also to dcso at 5 pt
*********** Release of dc 1.3 Patchlevel 3 *************************************
23-AUG-1996 Changed Parameters for dcsx at 5 pt, adjusted
|lc_hachek_accent|
23-AUG-1996 Added |zero_width| to the programme for the compound word
mark; without this statement the chardx value is wrong.
*********** Release of dc 1.3 Patchlevel 2 *************************************
3-JUL-1996 Added macro |clear_mode_guards|. This change makes modes like
|nechi| as defined in modes.mf 3.0 work.
Added missing |;| in the checking section
Corrected wording of one error message, hopefully
never to be seen by an end user.
All changes suggested by Andreas Schwab
Added file 00bugs.txt with known bugs.

17-AUG-1995 Changed positions 6, 7, and 6' of capital R from |vair| to
|.5[vair,cap_band]|, because |vair| looks too thin at 99.99pt

11-JUL-1995 Deleted macro |pi_stroke| from dxbase
