## Changes from PMX 2.5 to the Latest Full Release (2.72), 11 January 2016

2.501 (Note: new scor2prt)

- Bugfix: initialize index in PMX subroutine putorn to eliminate subscript error detected in some compilers
- Bugfix in scor2prt: Ignore special treatment of special symbols if they appear between double quotes.
- Tweak: move end of first part of line-break ties slightly to the right.

2.502 (Note: new pmx.tex)

- The height of a figured bass vertical stack can now be adjusted upward by an integral number of \internote by appending "+" and the number. Recall that it can already be moved downward 4\internote by prepending "_" (underscore). The two options can be combined to provide full control over the vertical position.
- Ties can now be represented with braces "{" before a note and "}" after. Both are equivalent to "t" after the note. (Thanks to Dirk Laurie).
- In pmx.tex all the commands of the form \font\...=\fontid sy1000 have been changed to \font\...=cmsy10 (Thanks to Olivier Vogel).

2.503

- Enable arpeggio left shift with ?-[x]
- Allow musicsize of 24 and 29.
- Bugfix: Fix bug introduced in 2.415 which caused error in printing replacement number in xtup.

2.504

- Gap between normal grace and main note: X[x] as option to the G command, where x is the gap size in notehead widths.
- Bugfix: og (segno) now works OK when nv .ne. noinst.

2.505

- A new global option AK activates special rules for vertical positioning of rests in two-voice staves. By way of background, without the new option, rests in two-voice staves have default positions based on a simple rule that is not context-sensitive: those in the lower voice (the one before "//") are 4\internote below their single-voice default positions, and those in the upper line are 2\internote above the single-voice default. The new option invokes a set of context-sensitive rules to set the default position. The baseline rule is to align the rest in a horizontal line with the next following note in the same bar. If there is no following note in the bar, then it is aligned with the next prior note. If there are simulataneous rests in both voices, the old rule is applied. When the AK option is in force, it only affects places where there are two voices in a staff. It may be toggled on and off at the beginning of any input block, using just AK. When the option is in effect, any user-defined tweaks on the height of a rest will supersede the option for that particular rest, i.e., the tweak will be applied relative to the single-voice default position.

2.506

- Fixes a bug in AK. Simultaneous, equal-duration rests will be positioned according to the default rules.

2.507

- Enhancement to global option AK for vertical positioning of rests in two-voice staves (see version 2.505): The option L ("look left") in a rest will cause the vertical position of that rest to be based on the preceding note, rather than the following one as is the default when AK has been issued
- Partial bugfix: In unbeamed xtuplets, the length of the bracket and position of the number are now adjusted to account for any inserted hardspaces.
- Bugfix: unbeamed xtups with two flags are now allowed.

2.508

- Allow grace notes in xtuplets.

2.509

- Correct small bug in arpeggio left-shifting (it got confused when there was more than one voice on a staff).

2.510

- Bugfix: Correct omission of character variable declarations in new subroutine getgrace introduced in 2.508.

2.511 (Note: new scor2prt named s2p2511.exe)

- Bugfix: Correct error in horizontal spacing introduced in 2.507.
- Experiment: Remove prohibition against tempo changes in MIDI macros.
- Bugfix in scor2prt: Make it work right when "R" command occurs at end of input block and "/" is on next line (as produced by M-Tx).

2.512

- Enable multiplicity down-up "][" within xtuplet

2.513

- Bugfix: If there is more than one rest at start of a beamed xtuplet marked as a forced beam, beam height and slope tweaks are now properly handled.
- Bugfix: If an xtuplet with multiplicity 2 or 3 starts with a rest, the rest is now printed correctly.
- Bugfix: Unbeamed xtuplets (with option 'a' on first note) with multiplicity 2 or 3 are now printed correctly.

2.514

- Bugfix: Correct horizontal spacing when after-grace is immediately followed by normal grace.
- Bugfix: Correct transpose register when it has been changed in a single after-grace.

2.515

- Bugfix: Correct error in automatic forced beams. Before the fix, if the beam did not start an integral number of beam durations from the start of the bar, incorrect results would occur.
- Bugfix: Properly center fermata over centered whole-bar rest.

2.516 (Note: new pmx.tex)

- Allow figures in voice #2.

2.517

- Allow figures in two voices, voice 1 and any other one.

2.518

- Bug fixes in 2-voice figures.

2.519

- Fix bug that prevented \sk from being output, misaligning some voices.

2.520

- New feature: special characters 2+, 4+, 5+, 6+, 9+ for figured bass. In the PMX string for any figure, follow the number by 's'. This uses the font cmrj from the new package figbas. You must install this font in your TeX setup for this to work.

2.521

- Bugfix: Font definition syntax corrected so no extra space is introduced.

2.602 (Note: new pmx.tex; requires eTeX)

- Allow 24 voices, beams, slurs. Require etex.
- Include comment about doubling size of internal buffer to 131072, requiring gfortran for Windows to compile.
- Correct slur indexing in linebreakslurs.
- Account for comment lines in line count for error messages

2.603 (Note: new scor2prt)

- In getpmxmod.for, decrease nline by 2 to fix locating errors following reading in an include file.
- Add some error messages in g1etset.for setup data

2.610

- Instrument-wise transposition: Ki[instrument #][+/-][trans amt.][+/-][new key]. For more than one instrument, may immediately repeat everything after "K". Must either be at start of score (right after setup), or if later, must be preceded by normal (full score) key change command K+0[+/-][new key]. Must be used with relative accidentals ("Ar"). Part(s) to be transposed must be entered in concert key, and will appear transposed in the score. MIDI behavior not yet tested. Has not yet been integrated into scor2prt, so for now if you want to make parts, only use Ki... as score-only (on line after "%%") and/or instrument only (on same line after %[Instrument #]).

2.613

- Set error trap if "D" is entered before any notes.
- Enhance "AS" to allow spacing adjustments tailored for either smallsize or tinysize. As before, "AS" must be followed by nv characters, but now they may be "0" for normal, "-" or "s" for small, or "t" for tiny. Still must set sizes of instruments with inline TeX.
- Bugfix: Fixed broken "K-..." in 2.610.

2.614

- Bugfix: revise raised dotted rests by separately raising rest and dot.

2.615 (Note: new scor2prt)

- Command "AS", described above under 2.163, now also causes staff sizes to change (in score only, not parts), so inline TeX is no longer needed to change sizes of selected staves.
- Scor2prt transfers partwise transposition commands Ki... (see 2.610 above) into parts.

2.616

- "Feature" added: Hairpin dynamics now may span input blocks.

2.617

- Repaired several obscure bugs related to platform and compiler dependencies; see pmxab.for for details.

2.618

- For letter and a4 paper respectively, commands "Acl" and "Ac4" set horizontal and vertical sizes and offsets that center the page with no further adjustments required in dvips.

2.619 (Note: new pmx.tex)

- Several changes at movement breaks to improve compatibility with M-Tx and musixlyr.

2.621

- Bugfix: Made keyboard rest positioning ("AK" command) work properly when there are rests are within xtuplets. Also fine-tune default positioning of number and bracket in unbeamed xtuplets containing rests. Position of both can still be overridden with options on first note command for xtuplet.

2.622

- New option in "K" command: "Kn..." inserts \ignorenats before signature change, supressing naturals in new signature
- Many small fixes in transposition and key changes with "K", "Ki", and "IT" to make MIDI come out OK. Basic function of "K" and "Ki" unchanged. "IT[+/- n1][+/- n2]..." now transposes MIDI by \internotes, not half steps as before. E.g. to transpose MIDI of 2nd instrument out of 3 up by one octave, use "IT+0+7+0". May also use to untranspose a transposing instrument that has been entered transposed, to make MIDI come out at concert pitch.

2.70 (Note: new scor2prt.exe and pmx.tex)

- Bugfix in AN, to make it behave as advertised, which is to assign user- defined names to part files rather than using the default.

2.71 (Note: new pmx.tex and MusiXTeX 1.21)

- Octave treble clef ("C8" command).
- In figured bass, apply vertical shift for remainder of line with option "v[-](number)" to the figure command
- Internal changes in multi-bar rests to accommodate changes in musixtex.tex.
- Slurs aligned with stem ends, postscript slurs only, option "v".
- Coda "oC".
- New, smaller segno "oG". Unlike "og", must enter on every staff.

2.72 (Note: new pmx.tex; still requires MusiXTeX 1.21)

- Bugfix when arpeggios go from one voice to another in the same staff.
- Further tweaks in multibar rests.
- Tweaks in centered full-bar rests.
- Fix bug in clef changes for multi-staff instruments.
