5 What is new in MetaPost beta version 1.091:
6 ----------------------------------------------------------------------
8 * Dash lists were interfaced incorrectly by the lua bindings.
10 * The Type 1 Font inclusion in the previous version produced invalid
13 * The configure script now also checks for sys/time.h
15 * The error message you get for invalid mem files now mentions the
16 name of the file as well as the nature of the problem.
18 ----------------------------------------------------------------------
19 What is new in MetaPost beta version 1.090:
20 ----------------------------------------------------------------------
22 This MetaPost release is based on MPlib. For those of you who are not
23 aware of the MPlib project yet:
25 MPlib is the name of the new, revamped version of the MetaPost
26 interpreter. It is implemented in Cweb, and internally consists
27 of a core library, an mpx generation library, and a frontend
28 driver program (mpost).
30 There are no changes to the MetaPost language, but nevertheless there
31 are some minor differences with the last pascal-web based version of
34 * The MPlib distribution is released under the GPL version 2 or,
35 at your option, any later version.
37 * The commandline is slightly different, run mpost --help for details.
39 * The mem file format is changed, you have to regenerate any
42 * The new mpx generation library includes the label generation
43 functionality that was previously provided by 'makempx', and
44 this internal code will be used instead of an external program.
45 That is, unless the MPXCOMMAND variable is set in the environment
46 or texmf.cnf. The 'mpware' programs became obsolete and are no
47 longer included in the distribution.
49 * Most of the memory configuration variables from texmf.cnf
50 have become obsolete due to dynamic reallocation. The four remaining
51 ones are 'main_memory', 'hash_size', 'max_in_open', 'param_size'.
52 These are only taken into account at mem generation time, the
53 values are stored in and reloaded from the mem file.
55 * The core MPlib library does not interpret an initial '&' as anything
56 special and it does not support re-initialization using a different
57 mem file either. The command line program mpost _does_ interpret '&'
58 as an alias for the -mem switch to preserve (some) compatility.
60 * The MPlib distribution includes lua script language bindings.
62 Following are the NEWS items for the previous beta releases of MPlib.
64 ----------------------------------------------------------------------
65 What is new in the beta release of MPlib 1.090:
66 ----------------------------------------------------------------------
68 * The lua bindings to MPlib are added to the distribution, and
69 build.sh can now build an mplib.so loadable module for lua
70 (this needs an installed lua 5.1 distribution)
72 * Some internal macros are renamed so that the exported C structure
73 fields could have better names, and a new document (mplibapi.tex)
74 provides the documentation of the C api and Lua bindings.
76 * The texmf and manual trees are now included again.
78 * (un)dumping mem files is delegated to a separate cweb source file.
80 * All gcc-isms in the build and configure scripts have been removed.
82 * The kpathsea library is updated.
84 ----------------------------------------------------------------------
85 What is new in the beta release of MPlib 1.085:
86 ----------------------------------------------------------------------
88 * Determination of the mem name to use in non-ini mode is now much
89 closer to the web2c approach.
91 * There is now a magic word in the beginning of the mem file to make
92 sure it is written by the correct version of MPlib.
94 * Fixed the disappearing comment sign in the to-be-typeset document
95 created by the mpx generation subsystem.
97 * Various identifiers have been renamed to avoid clashes (that prevented
98 the source from building correctly on many platforms)
100 * A great many small changes and fixes have been added after running
101 splint on the generated C source.
104 ----------------------------------------------------------------------
105 What is new in the beta release of MPlib 1.080:
106 ----------------------------------------------------------------------
108 * The MPlib distribution is released under the GPL version 2 or, at
109 your option, any later version. The copyright statements in the source
110 files have been updated to reflect this.
112 * The mpost program banner now contains the kpathsea version, and no
113 longer mentions the fact that the source is now cweb at all.
115 * The mpost program once again supports 'E' error responses.
117 * There are some minor internal API changes, but there is still no
118 documentation for the API, so that is not very interesting yet.
121 ----------------------------------------------------------------------
122 What is new in the beta release of MPlib 1.060:
123 ----------------------------------------------------------------------
125 * The MPlib distribution is released under the GPL version 2.
127 * This release is the first that replaces the old metapost distribution
128 completely. The executable is now named 'mpost' with engine name
131 * The release now includes a cweb implementation of the makempx
132 functionality that is linked into the mpost executable.
133 This internal code will be used unless the MPXCOMMAND variable is set.
134 Because of this functionality, the mpware directory is no longer
135 included and the standalone programs 'makempx', 'newer', 'mpto',
136 'dvitomp' and 'dmp'. are no longer maintained.
138 * This is the first development release of the new cycle, and contains
139 all of the functionality of Metapost 1.005. The mpost version is now
140 1.060, and the special version number for the cweb version has been
141 removed from the banner.
143 ----------------------------------------------------------------------
144 What is new in the alpha release of MPlib (0.20.0):
145 ----------------------------------------------------------------------
147 * Two bugs in MP 1.002 were fixed by Giuseppe Bilotta, both fixes
148 are about polygonals pens and will be included in the upcoming
149 MP 1.003 release also.
151 * It is now possible to ask for the envelope of a path drawn as
152 traced by a (non-elliptical) pen:
155 p = fullcircle scaled 30;
156 q = envelope pensquare of p;
158 * There is a lua interface now, and it is already used by luatex.
160 To play with this, currently the best solution is to fetch the
161 0.25.0 beta of luatex: http://foundry.supelec.fr/projects/luatex
162 This embeds MPlib 0.25.0 as well as its documentation.
164 * Many bugs were fixed.
166 ----------------------------------------------------------------------
167 What is new in the alpha release of MPlib (0.10.0):
168 ----------------------------------------------------------------------
170 * The source is converted to cweb, and split into a library part
171 (mpdir/lib/*.w) and a frontend executable (mpdir/mpost.w).
173 * The front end executable is named "newmpost", this takes
174 care of configuring the MPlib library via C code, and uses
175 kpathsea for file searching. There is no change file involved,
176 and the web2c runtime library is not used.
178 * Some of the internal arrays now grow dynamically when needed:
181 * the string pool and number of strings
182 * the font memory and number of fonts
183 * the number of "readfrom" and "write" files
184 * the path segment size
185 * the input nesting stack
186 * the number of new internals
187 * the TFM writing arrays (but these are limited by TFM format)
189 Still not doing that (so these can only be changed in --ini mode):
193 * the number of simultaneous macro parameters
194 * the level of "input" file nesting
196 * The following command-line options are ignored by the front-end
199 -[no-]file-line-error
202 -[no-]parse-first-line
208 The other web2c command-line options should work as normal.
210 * the mpware tools are not in this distribution, their functionality
211 will eventually be assimilated into the frontend application.
213 * the build process depends on a local "ctangle" command being in the
214 path, for now. The confiration and building system is not yet complete.
216 * API documentation is still missing, but the MetaPost input language
219 ----------------------------------------------------------------------
220 What is new in version 1.002:
221 ----------------------------------------------------------------------
223 * Version 1.001 introduced a memory allocation error in mpto that could
224 result in the program looping endlessly
226 ----------------------------------------------------------------------
227 What is new in version 1.001:
228 ----------------------------------------------------------------------
230 * The default cmyk 'black' color now uses only black, not all four
231 ink colors (after a discussion on the mailing list).
233 * Some issues were reported with the new turningnumber algorithm,
234 all known problems are now fixed.
236 * Gábor Braun discovered that mpost did not always download the font
237 encodings into all the created output files.
239 * Akira Kakuto and Hartmut Henkel found some small issues in mpto
240 regarding trailing and leading whitespace.
242 * A fix for the 'Helvetica' entries in trfonts.map was provided by
243 Werner Lemberg, and Michail Vidiassov supplied two extra font
244 entries for troff.map (Symbol and ZapfDingbats). Karl Berry
245 provided the new file troff-updmap.map, to be used by the updmap
248 * Mpost now supports web2c's --output-directory option.
250 * Any warnings about missing fonts and characters are now always
251 written to the terminal as well as to the log.
253 * Now that makempx is a C program, it needed a different install line
254 in build.sh. Also, Olaf Mersmann contributed a patch to recognize
257 * Luigi Scarso found some typing errors in the web source that prevented
258 clean weaving of the source.
260 * Stephan Hennig fixed a number of problems in the manual (mpman.tex)
261 and the introduction paper (mpintro.tex). He also wrote new sections on
262 how to preview metapost graphics and on how to use metapost graphics
263 inside other documents. On top of that, the manual is now hypertext-aware,
264 and fixes for a whole series of small problems have been applied.
266 ----------------------------------------------------------------------
267 What is new in version 1.000:
268 ----------------------------------------------------------------------
270 * The use of DSC (document structuring) comments has been
271 been cleaned up, thanks to comments by Michail Vidiassov.
273 * By setting prologues to 2 or 3, you can ask MetaPost to
274 reencode and include the used labels fonts in the output,
275 thus creating proper Encapsulated PostScript files even
276 if labels are present.
278 * Support for greyscale and cmykcolor models is added.
280 * The new drawing options "withprescript" and withpostscript"
281 allow the user to attach PostSCript special text to a specific
284 * Setting the new internal "mpprocset" to 1 will make MetaPost
285 create a somewhat extended preamble that defines shortcuts
286 for the postscript commands (e..g "l" instead of "lineto").
287 For big images, this can help shrink the output a bit.
289 * The pool file is now integrated in the executable, so there
290 is not separate 'mp.pool' anymore, except at build time.
292 * Groff support is redone, and dmp now uses kpathsea searching.
293 Groff related changes are thanks to the efforts of Werner
294 Lemberg and Michail Vidiassov
296 * makempx is now a compiled executable on all systems,
297 thank you Akira Kakuto
299 * The error for 'special's longer then 255 characters
300 is removed, so specials can now be of any length.
302 * There is new turningnumber implementation that attempts
303 to find the mathematically correct "turningnumber" of a
304 path. The formulae are derived from a mailinglist discussion
305 between (especially) Dan Luecking and Giuseppe Bilotta.
307 * The manual is updated and modernized. It is currently
308 maintained by Stephan Hennig and Troy Henderson.
310 ------------------------------------------------------------------
311 Changes in version 0.920:
312 ----------------------------------------------------------------------
314 * Fixed a long-standing bug in web2c where changing values of the
315 memory_size setting in web2c could cause crashes and other random
316 problems. The memory array size is now written to the dump file
317 and loading is aborted if the values do not match.
318 * Implement configurable figure output filename templates.
319 * Implement cmyk, greyscale, and marking only color models.
320 * The mpost executable is now version 0.920
322 ----------------------------------------------------------------------
323 Changes in version 0.902:
324 ----------------------------------------------------------------------
325 * Fix a bug in mpto resulting in correctly placed labels (with
326 thanks to Dan Luecking)
327 * Fix a bug blocking compilation of dmp on MacOSX
328 * The mpost,dmp,mpto executables are now version 0.902
331 ----------------------------------------------------------------------
332 Changes in version 0.901:
333 ----------------------------------------------------------------------
334 * A corrected bugfix for bug item 3 from version 0.9 (the old fix
335 made metapost fail the trap test)
336 * Included mpost.mp for mem generation
337 * Updated the trap test output.
338 * The mpost executable is now version 0.901
340 ----------------------------------------------------------------------
341 What is new in version 0.9:
342 ----------------------------------------------------------------------
343 1. There is a new internal quantity called mpversion that reports the
344 current metapost version, and the version information is also written
345 to the PostScript file.
346 2. The LaTeX sources of the mpman, mpintro, and mpgraph manuals have
347 become part of the distribution package.
348 3. TEX.mp now has TeX format support through a pair of macros called
349 TEXPRE() and TEXPOST(). This llows you to process the contents of
350 the TEX() macro with, for example, LaTeX (instead of plain TeX).
351 An example is given in the manual.
352 4. metapost now writes a %%HiReSBoundingBox comment
353 5. The EPS output no longer contains actual spaces within PostScript
354 strings as for example output by label("a space"), but their
355 octal escape (\040) instead.
356 6. The EPS output now also has a %%BeginProlog DSC comment
357 as well as %%EndProlog
358 7. The comments in the Web source have been changed to point out
359 that on modern machines, acquiring the random seed has actually
360 become a system-dependant operation (a granularity of whole seconds
361 is not small enough on new machines).
362 8. The 'newer' command now accepts more than 2 arguments, testing
363 each of the files in turn.
365 ----------------------------------------------------------------------
366 Bugfixes in version 0.9:
367 ----------------------------------------------------------------------
368 1. Documentation improvements: all known errata and typos have been
369 removed, better explanations of e.g. dash patterns and dotlabel have
370 been provided, and a number of omissions has been rectified.
371 2. The BoundingBox was not computed correctly when a filldraw command
372 with a noticeable pen size was used at the edge of the picture.
373 3. Paths starting with degenerate constructions like (0,0)--(0,0)--(0,0)
374 could overflow memory.
375 4. The PostScript output could accidentally contain 8-bit characters
376 within PostScript strings in previous versions because a test was
377 shared between terminal printing and PostScript printing.
378 5. A bug has been found in the assignment of serial numbers to independant
379 variables in metafont 2.71828. This bug affected MP as well, and the
380 same patch has been applied.
381 6. The turningnumber was sometimes wrong in unexpected ways. The new
382 implementation is still sometimes wrong (when there are strange path
383 segments involved), but in a much more predictable way: the new code
384 always draws straight lines between the actual points, and calculates
385 the turningnumber based on that path instead of the actual path. The
386 effect is that cusps and loops within segments are now completely
387 ignored. A more thorough fix of turningnumber is planned for the
389 7. There was an 'off by one' error in dvitomp wrt. the interpretation
391 8. mpto uses a new TeX macro for the generation of labels, making it
392 more robust wrt. strange user code within the actual label text.
393 9. A missing colon in boxes.mp has been added
394 10. A missing save in mfplain.mp has been added
395 11. The generisize in boxes.mp has been fixed so that it now accepts [[ as
396 a valid variable name
398 ----------------------------------------------------------------------
400 ----------------------------------------------------------------------
401 The only change was to fix the code for transforming a picture that
402 contains a filldraw. Version 0.64 introduced a bug that caused an
403 inappropriate memory reference in that case.
405 ----------------------------------------------------------------------
406 What is new in Version 0.64:
407 ----------------------------------------------------------------------
408 1. A new primitive command closefrom filename closes a readfrom file
409 so that subsequent calls to readfrom with that file name will go back
410 to the beginning of the file.
411 2. The ^^ notation for unprintable characters is now used only when printing
412 on the terminal or the log file. Internal computations and the write
413 command are all 8-bit clean. (This is partly due to material in mp.ch
414 that changes the initialization of the xchr array. Without these
415 system-dependent changes, the write command would map all non-ascii
416 characters to spaces.)
417 3. Arithmetic overflow during a comparison such as 20000>-20000 is now
418 ignored. This avoids extraneous error message when using the graph.mp
420 4. Transformations with negative determinants now work properly on pictures
421 drawn with polygonal pens.
422 5. When the readfrom operator is applied to a file that does not exist,
423 an attempt to close a non-open file could cause problems in some
424 implementations. This has now been fixed.
425 6. Using draw picture_expression withpen where the picture_expression
426 was a scaled picture containing dashed lines, the dash lengths would
427 change. This bug has been fixed.
428 7. The dashpart operator could return an invalid picture or a picture that
429 is not properly scaled. This has also been fixed.
430 8. The |char_base| variable could become negative when using fonts that
431 do not start at character 0. There was also bad Pascal code in function
432 b_open_in. This has all been fixed.
433 9. Dvitomp has been fixed to avoid a font data structure problem that
434 could cause some characters to come out in the wrong font when you
435 mix virtual and non-virtual fonts.
436 10. Dvitomp now correctly prints font names when there is a checksum
437 mismatch, and it aborts instead of just printing an error if a tfm
439 11. In plain.mp, the drawdblarrow macro now uses filldraw so that it works
440 better with large pen sizes.
442 ----------------------------------------------------------------------
444 ----------------------------------------------------------------------
445 When prologues is negative, the output files use full precision for
446 coordinates in "%%BoundingBox" comments. In btex..etex blocks,
447 "number too large" and "invalid character" errors are suppressed.
448 The result of btex..etex is now guaranteed to be in a setbounds path
449 so that a for...within iteration will always treat it as a unit.
451 There are also some obscure bug fixes involving string compaction when
452 scanning a file name or when mp is compiled in debug mode. Some possible
453 identifier name conflicts and range check errors have also been fixed.
456 ----------------------------------------------------------------------
458 ----------------------------------------------------------------------
459 This version fixes an obscure bug that could cause certain perfectly valid
460 strings to be printed as "???" or " NONEXISTENT". It also includes a minor
461 fix to the PATHEXPAND code that prevents running out of file descriptors.
464 ----------------------------------------------------------------------
465 What is new in Version 0.63:
466 ----------------------------------------------------------------------
467 1. Backslashes in the PostScript output are rendered correctly. They used
468 to come out as (\) instead of (\\).
469 2. Recycling an independent variable should no longer cause spurious overflows.
470 (This bug was recently found in mf.web.)
471 3. Pythagorean addition should now be faster in certain trivial cases.
472 4. Rotating text by arbitrary angles should no longer cause bad PostScript
473 output. The problem was that arguments to "fshow" could be inaccurate.
474 5. Obscure bugs inherited from mf.web are now fixed. These involve
475 balancing parentheses showing on the terminal, reporting the correct
476 line number in case of buffer overflow, and removing spurious reference
477 counts that could effect end-of-job statistics.
478 6. Fonts with ec=255 should no longer cause mp's PostScript output routines
480 7. When mp's string mechanism was heavily used, file names could occaisonally
481 be printed on the terminal and log file as "(?)". This has been fixed.
482 8. Setting PATHEXPAND in site.h causes mp, dvitomp and dmp to understand "//"
483 in path variables as "search multiple levels of subdirectories". This is
484 for compatibility with recent versions of the Web2c TeX distribution.
485 9. A typo in mpware/makempx and mpware/troffmpx has been fixed. Previous
486 versions of these scripts would not run on some systems.
487 10. Data files *.d have been added to the doc directory. These are used by
488 doc/mpgraph.mp which generates figures for "Drawing Graphs with MetaPost".
489 11. Typos in mpintro.tex and mp.web's TeX material have been fixed.
490 12. Files examples.mp, mpintro.tex and mpintro.bib have moved from mplib to
492 13. The author's email address now appears in the README file.
495 ----------------------------------------------------------------------
496 Macros added to the mplib directory between Versions 0.50 and 0.62:
497 ----------------------------------------------------------------------
498 rboxes.mp is a slightly more general version of boxes.mp
499 TEX.mp provides a way of running tex dynamically instead of as a pre-processor
500 graph.mp, format.mp, and sarith.mp are documented in doc/mpgraph.ps
501 (This is the same as ftp://netlib.att.com/netlib/att/cs/cstr/164.ps.Z)
502 marith.mp, string.mp, texnum.mp, and troffnum.mp are low-level packages
503 used by graph.mp, format.mp, and sarith.mp.
506 ----------------------------------------------------------------------
507 Other minor bug fixes subsequent to Version 0.60
508 ----------------------------------------------------------------------
509 1. plain.mp has been fixed so that the x**y works properly when x<0 and y is
511 2. Programs mptotex.c and mptotr.c which extract btex..etex material have been
512 fixed so they work properly with input files that do not end with a newline
514 3. Program dmp.c which handles troff output from btex..etex blocks has been
515 modified to avoid outputting any non-ASCII characters that the C function
517 4. Program dmp.c no longer gets troff graphics specials confused with text.
518 This seldom matters because btex..etex blocks are unlikely to contain
520 5. Pictures containing clipped subpictures could come out with some colors
521 in the subpicture wrong.
522 6. Colors in PostSript output were not being restricted to the standard 0..1
524 7. Transforming a path or a pen should no longer generate extraneous overflow
525 errors in certain unusual situations.
526 8. Drawing with a degenerate 2-vertex polygonal pen such as penrazor should
527 no longer cause an infinite loop in certain unusual situations.
528 9. There were some bugs in the mfplain macros. (These macros are designed
529 to similate plain METAFONT.) The drawing and filling macros now apply
530 currenttransform to the path but not the pen rather than vice versa.
531 The predefined modes now set o_correction to 1.0.
532 10. For security reasons, mp can no longer read or write files whose names
536 ----------------------------------------------------------------------
537 Changes to the MetaPost language between Version 0.50 and Version 0.60
538 ----------------------------------------------------------------------
539 1. New operator `readfrom <filename>' and new command
540 `write <string expression> to <filename>' do file I/O. Plain defines
541 a special string EOF that readfrom returns to indicate end-of-file
542 and write..to understands as well.
543 2. New iteration type `for p within <picture expression>: <loop text> endfor'
544 iterates through the interior components of the picture. An `interior
545 component' is a single pen stroke, filled outline, or piece of typeset
546 text. A part of the picture enclosed in a clipping or setbounds path
547 also counts as an interior component. If the whole picture is enclosed
548 in such a path, the for..within iteration looks inside. Note that a
549 picture generated by btex..etex is enclosed in a setbounds path.
550 3. The length operator now applies to pictures. It returns the number of
552 4. New boolean operators stroked, filled, textual, clipped, bounded test
553 the first component of a picture. A picture enclosed in a clipping or
554 setbounds path counts as a single component.
555 5. Part extraction operators now work for pictures. Standard operators
556 redpart, greenpart, bluepart apply to the color of the first component
557 and xpart, ypart, xxpart, xypart, yxpart, yypart extract parts of the
558 tranformation that has been applied to a text component. If `textual p'
559 is false, the transform components are all zero; if `clipped p' or
560 `bounded p' is true, the color parts are all zero. Additional operators
561 fontpart, textpart, pathpart, penpart, dashpart extract other information
562 from the first component of a picture. They all return null values when
563 the first component has the wrong type: fontpart and textpart return
564 null strings; pathpart returns the path (0,0); penpart returns nullpen;
565 and dashpart returns nullpicture.
566 6. The construction `dashed nullpicture' is now a no-op. It used to be
568 7. The clip and setbounds statements used to ignore operations on empty
569 pictures. Now they do not.
570 8. Structuring comments in the PostScript output are now based on EPSF-3.0
571 as described in the 2nd Edition of the PostScript Reference Manual.
572 When prologues is 0, some structuring comments are included but the
573 output is not flagged a `conforming document'. Previous versions of
574 MetaPost behaved similarly but used slightly different structuring
576 9. When warningcheck is 0, numeric tokens and results from the hex and
577 oct operators can be as large as 32767.99998. The old limit of about
578 4096 applies only when warningcheck is positive.
579 10. Various optimizations should make the output a little more compact.
580 11. For PostScript engines that obey the scan-conversion rules documented
581 in the 2nd edition PostScript Language Reference Manual, hrules and
582 vrules in btex..etex blocks should now come out to exactly the right
583 number of pixels. The change affects all pen strokes drawn in MetaPost
584 It is implemented via PostScripts dtransform and idtransform operators.
585 12. A bug involving setbounds and MetaPost's corner operators has been fixed.
586 13. Degenerate elliptical pens no longer cause PostScript to divide by zero.
587 14. Fixed a very obscure bug involving readstring and end-of-file.
588 15. String compaction statistics are now printed correctly when the job
589 terminates with tracingstats positive.

594 Changes to the source files between Version 0.50 and Version 0.60
595 ----------------------------------------------------------------------
597 CHANGES to ./README.MP
598 The installation instructions should now be clearer. They also explain
599 how to cope with verious versions of WEB2C.
602 I removed unused entries and clarified instructions in commentary material.
603 Confusing comments about possibly merging it with the WEB2C version of site.h
604 were removed--I think such merging is a bad idea.
606 CHANGES TO ./Makefile, mp/Makefile, mpware/Makefile:
607 Improved default settings, simplified the `install' recipe,
608 fixed a few missing depencies, portability problems, etc.
611 mp/mp.defines, mpware/mpware.defines, mpware/dvitompext.c
612 TO mp/mp.def, mpware/mpware.def, mpware/dvimpext.c
613 (The names also changed in the Makefiles and convert scripts)
615 CHANGES TO mp/mp.web, mp/mp.ch, mp/mp.def, mp/mpext.c:
616 Lots of new features were added as noted above. The only new system-
617 dependencies are for `readfrom' and `write...to'.
618 The change file now increases max_read_files; it doesn't bother with
619 max_write_files, but perhaps it should. There is a new change entitled
620 "Path selector for..readfrom file". From the web2C sources I borrowed
621 a change "`logname' is declared in <unistd.h> in some systems". I also
622 added a PASCAL-like eof() routine to mpext, removed a change entitled
623 "avoid using eof() in read_psname_table" and added a new change
624 "[48.1199] `eof'...[in read_mem_file]".
626 Reorganization of math routines in the mp directory:
627 I moved the floating-point math routines from mpext.c to mpath.c. A
628 C-language version of the standard math routines was moved from mpmath.c
629 to a new file pmath.c for use in mathtest only. This required chages to
630 mathtest.c and time.c (also used only for mathtest). The point of all
631 this is that there is now just one copy of the floating-point math routines
632 and it is used for mathtest and (optionally) for mp itself.
634 Routines in doc and mp/trapdir:
635 The output was updated to Version 0.60. Another test file mptrap.mp
636 tests new features. There have also been minor updates to the manual,
637 although the new features for Version 0.60 are not included yet.
639 CHANGES to macros in mplib:
640 A minor change to boxes.mp should make it more robust. Changed default
641 setting of tracinglostchars in mfplain.mp and plain.mp. Added a string
642 constant EOF to plain.mp for use with readfrom and write..to.
643 Changed mproof.tex to make it more portable as suggested by Knuth.
645 CHANGES to mpware/dvitomp.web, mpware/dvitomp.ch:
646 The web file was changed to output rules as horizontal or vertical
647 penstrokes with butt endcaps. This also affected dvitomp.ch. Also in
648 dvitomp.ch, put terminal output on stdout instead of stderr and require
649 the output file to be given on the command line.
651 CHANGES to mpware/makempx, mpware/troffmpx:
652 Added comments explaining what path names need fixing. Portability improvements
653 and dvitomp's output change affect makempx only.
655 CHANGES to mpware/mptotex.c mpware/mptotr.c mpware/testex.err mpware/testex.mp:
656 Ignore an initial newline in the TeX (or troff) material to avoid generating
657 a blank line in the output file. The test file now covers this case.
659 CHANGE to mpware/newer.c
660 Minor changes to make it compile in strict ANSI/POSIX environments.
