What's new in this version:

Render:
- ensure that dry run render does not fail if the input tracks or media items are not named
- fix sample rounding inconsistencies in postprocessing
- fix various render actions that render parent send channels only within time selection
- if rendering only one file and adding to project, name the track after the file
- limit text length for prompt to keep/delete partially-rendered files
- respect "cancel all" when rendering queued projects
- restore support for $namenumber wildcard
- when rendering master mix and adding rendered files to project, name the new track 'MASTER (rendered)'
- results window respects user preference for spacebar used for navigation, in which case ctrl+space activates play/stop
- results window screen reader accessibility improvements

Big clock:
- fix display of region/marker color when using unicode text
- fix parsing some time format specifiers
- support $timesel(format)
- support $ifprev, $ifnext, $ifboth, to display text conditional on whether the previous/next wildcard resolves to anything
- support $ifprevis, $ifnextis, to replace previous/next wildcards if they resolve to a specific condition
- support $preroll
- support formatting project time in total beats regardless of measures

Peaks:
- detect when peaksbuild failed (e.g. due to network disk interruption) and prevent creation of invalid peakfile
- improve performance when scrolling large views
- improve display consistency with looped items
- improve efficiency when using multiple enhanced peaks views (e.g. spectral peaks + LUFS graph)
- improve spectrogram artifacts at start of item when zoomed-in
- optimize drawing with many items that end before the current view

MIDI:
- support chase/reset of Poly Aftertouch
- fix exploding MIDI items by pitch/channel for items that ignore project tempo
- when opening quantize window, automatically switch to 'selected notes' if some notes are selected and unselected notes are quantized
- add option to control whether editor configuration changes made will be the default; add action to save default MIDI editor config
- improve editor configuration granularity for note shapes vs view type

Item notes:
- prevent possible crash when closing item notes window
- prevent word wrapping on right edge of arrange when item is partially scrolled offscreen

Media explorer:
- fix previewing audio from video files via project tracks with more track channels than source audio channels
- fix issues with length string formatting/rounding

Meters:
- fix incorrect meter drawing in response to track selection changes
- improve dB scale positioning with certain themes when displaying gain reduction metering

ReaScript:
- add ResolveWildcards(), to resolve any wildcard string that is valid in the Big Clock
- update Main_SaveProjectEx() to ignore calls with empty output filename string

Theme:
- fix WALTER warnings on unpacked default theme
- support specifying spacing between track meters and gain reduction meters, via .vu.div (see documentation)
- if gain reduction meter spacing is not specified, use half the specified track meter spacing

Undo:
- prevent extra undo points when loading FX with default user presets
- prevent extra undo point additions following CLAP preset load

Wildcards:
- $tempo wildcard properly accounts for tempo beat basis
- $tracknameornumber resolves to "Track 01", etc if the track has no name

Actions window:
- prevent delete/edit/duplicate for plug-in registered actions

Debug:
- add track arrange rendering statistics, accessible via debug console with arrange_perf command

- fix run-FX-when-stopped for master FX when project has no normal tracks

LTC generator:
- improve waveform generation

Media item properties:
- improve screen reader accessibility

Recording:
- fix preview display for autopunch selected items when first punched item is offscreen

Spectral edits:
- improve behavior when forcing mono peaks is enabled

Text drawing:
