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.

            Don't interpolate |slant|
            Corrected slant for dcfi
            (the latter 7 changes were suggested by Ulrik Vieth)

17-MAY-1996 Added |penstroke| to the |killtext|ed macros
            New macro |clear_memory| to free some memory
            after parameter interpolation

            Added 30pt size (2986) to dcstdedt.tex
            Made parameters of dcsl the same as dcr.mf, except,
            of course, slant (Reported by Ulrik Vieth)

            Made En- and Em-dash equal to hyphen in monospaced

            Added kernings for nanovolts and hektowatts
            Gave the cwm |x_height#|
            Made the typewriter fonts really monospaced
            (including ffl and ffi ligatures)

            Changed def's in |dxpseudo.mf| to vardef's (found by 
            Andreas Schwab)
           
24-APR-1996 Added |lower.dot_size#| to dctc.mf, removed
            |lower.uu#| from the same file.
            Changed the |basedef|-line for dcbi to contain unrounded

            After some solid hacking the fonts compile again
            Gone through the easern and western european letters,
            did some clean up (character names, placement of \~N).

14-APR-1996 Buildt in changes from plfonts 1.07 to fix resolution-
            dependent metrics. This affects the following characters
            and macros:
            dxpunct.mf: French opening and closing quotes
            dxruwest.mf/dxrueast.mf: All letters with acute, hungarian,

            pos 4 lighter, moved pos 4 a bit leftwards. 
            Increased width of guillemets. Changed `guillemot' to 
            `guillemet' in order not to copy A*'s spelling error.

28-FEB-1996 Applied fixes from cm85.bug
            dxrulett.mf, letter J: pickup tiny.nib; bulb(3,4,5);  % bulb

            dxrllett.mf, letter m:
             lft x1l=hround(2.5u-.5stem); x1l=x1'l=x2l=x2'l; % stem, sic
             lft x3l=hround(.5w-.5mfudged.stem); x5-x3=x3-x1;
             if not monospace: r:=hround(x5+x1)+r-w; fi  
                                            % change width for better fit
            dxrulett.mf, letter Q: Added penlabel No. 8

            Fixed bug #3: (Font identifier of dcci)
            Fixed bug #14: Disappearing hairline of digit `8'
            by applying fix to cm fonts of 1989.
            From #15: Fix to italic l:
            old: top y1=h; x1=x2; filldraw stroke z1e--z2e;  % stem
            new: top y1=h; x1=x2; filldraw stroke z1e--z2'e;  % stem
            Did the same to \l, \'l and \v l in dxleast.mf
            Marked Fixed and partially fixed bugs in 00bugs.txt

 6-NOV-1995 Released file 00bugs.txt with list of `known bugs'

*********** Release of dc 1.2 **************************************************
31-AUG-1995 Adjusted german scharfes s
            Tuned spread for dcbx
            Adjusted semicolon
            Removed unused parameter uu# from parameter files and 
            from dxbase
            Restored line | forsuffixes $=notch_cut,cap_notch_cut: if $<3: 
            $:=3; fi endfor| in dxbase from cmbase.
            Did some finish: file headers, documentation files,
            deletion of old files

28-AUG-1995 Added kerning Wn and Vn (polish/russian proper names)
            Kern italic "W" like "V" instead of "T"

24-AUG-1995 Made dcsi and dcso conformant with dcss and dcsx
            Made single size parameter files for dcssdc10.mf,
            dcsq8.mf, dcqi8.mf, dclq8.mf, and dcli8.mf
            Added invisible fonts idclq8.mf and idcli8.mf
            Deleted old files dcssdc.mf, dcqi.mf and dcsq.mf
            Made SliTeX-style `I' work
            Added boolean parameter |one_serif| to control base
            serif on digit `1'
            Added parameters for dcfb0500 (Fibonacci font), corrected
            basesizes to be Fibonacci numbers.
            |notch_cut#| and |cap_notch_cut#| are measured in |pt#|, not
            in |1/36pt#|. Corrected in several parameter files.
            Tuned again the sans parameters, this time for small sizes;
            dcsx0500 works now, but it is more condensed than dcss0500

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
            Undid the previous change again, since it causes more trouble 
            at low sizes than it saves a really large ones.
            Changed |math_spread| in cmr to [-.2] for 17.28pt
            Did the same for dcsl, dcss, and dcsi
            Completely retuned the parameters for sans serif fonts.
            dcsx is now always bolder then dcss, dcss much brighter
            then in release 1.1
            Tuned height of acute accent again.

16-AUG-1995 Added some sidebearings to the double quotes
            Added kerning for kV, kW, mV, mW, eV, Vv (Vvedensky)
            Added kerning for \'n, \v{n}, \eng, and \~n
            Added kerning for ,,j, ,,g, and ,,y
            Added kerning between boundarychar and quotes
            Defined |lig_O_table| and |lig_C_table|

11-JUL-1995 Deleted macro |pi_stroke| from dxbase
            Renamed second argument of the circle accent macros to
            |y_bottom| (was |y_center| bzw. |y_move|, which gives a

            (Problem reported by Klaus Barthelmann, Mainz).
            There is another problem with the parameters left,
            causing the `=' sign to collapse at large sizes, ditto
