Starting at 0.5.0, all notable changes to Coldtype will be described here (briefly). Edit: looks like I forgot this existed, so we're starting again at 0.5.16

• coldtype.fx.skia
• SkiaImage (subclass of DATImage, which has been moved to coldtype.img module)

• .phototype/.color_phototype methods on DATPen — these are now "chainable" methods in the coldtype.fx.skia module, and can be applied by importing ala from coldtype.fx.skia import phototype and then chaining to a pen, .ch(phototype(...))

• Minor improvements to the self-rasterizing/drawbot-renderer, to support transparent backgrounds

• @drawbot_script and @drawbot_animation from the global import; now reside and can be imported from coldtype.drawbot module

• Quoting paths in blend_frame

• unicodedata2 from primary installation requirements, in order to make blender installation smoother (i.e. not require Include header-copying from python source tarball) — thanks @colinmford!

• New features for managing meshes in BlenderPen
• embedded profiles, so -p b3d should now work globally

• duration keyword for @animation, since it’s redundant to timeline=<int> shortcut

• Support for kp and tu in Glyphwise

• Support for single-char Glyphwise
• Glyphwise now returns DATPens, not DraftingPens

• Support for multi-return styler fn for Glyphwise
• Coldtype panel for @b3d_sequencer

• Better MIDI primitives
• coldtype midi midi viewer

• Better axidraw primitives in new coldtype.axidraw namespace, demonstrated in test/visuals/test_axidraw.png
• New numpad special variable that can handle up to 9 special actions, triggerable from the numpad with the viewer enabled

• Dependency on PyOpenGL-accelerate in the [viewer] extra — not really sure why that was there to begin with.

• Restored some audio capabilities, via audio= keywords and the new ConfigOption.EnableAudio/KeyboardShortcut.EnableAudio

• General tidying, particularly for use in [notebook]

• Dependency on noise in [viewer]

• Support for configurable BLENDER_APP_PATH
• Better support for Windows-Blender workflow

• Support for gif export in @notebook_animation.show

• strip= kwarg on StSt (defaulting to True) so incoming text is automatically stripped (but can be overriden as in the Glyphwise use of StSt)
• coldtype.blender.fluent experimental chainable interface for direct manipulation of blender objects

• Support for lineTo's in distribute_on_path
• More coldtype.blender.fluent interface
• Ability to exit from renderer with -1 in prenormalize_filepath

• @ui decorator idea, to be used/tested in Goodhertz plugin-builder

• .depth, .split, .wordPens, .walkp
• î and ï for index and indices, also both of those on DraftingPen now, since they shadow functionality of mod_contour and map_points
• utag in walk.data
• camelCase throughout examples, headed towards standardizing on that
• .geti for time-based fetch in AsciiTimeline

• style= on precomposed/@renderable-cached

• MidiTimeline to replace MidiReader (MidiTimeline uses standard Timeline capabilities rather than Midi-specifi classes)
• AsciiTimeline improvements and changed api, old []-style access replaced by .ki; keyframe support also added, via .kf; many new examples in examples/animations/ascii_*
• Easeable class to encapsulate all easing functionality, i.e. a Timeable bound to a frame value, meaning frame values can now be implied on all @animation-bound timelines (via Timeline.hold)
• Generic lyric-video sentence building on timelines, available contextually as .words on a timeline (example in examples/animations/ascii_words.py) (adapted from older Sequence class (not recommended for use), originally developed for lyric video animation in Premiere, though works better now with Blender)
• Automatic timeline viewer, available with -tv 1 command-line arg or toggleable with V key in viewer app
• A lot more examples
• Normalized behavior of point= handling in .scale/.rotate/.skew
• Manual-drive BlenderTimeline

• Implicit BlenderTimeline on @b3d_animation and @b3d_sequencer
• .progress method (in favor of new Easeable apis)

• .e now defaults to loops=1, rather than loops=0

• Audio support via pyaudio

• Error where windows can't watch non-existent file
• Error where windows barfs on os.uname

• coldtype.runon.runon abstraction for chained/fluent method calling on nested lists
• coldtype.runon.path i.e. P as a drop-in replacement for DATPen/DATPens (should be fully backwards compatible), which extends coldtype.runon.runon

• File watching on windows

• watchdog dependency (using stat().st_mtime polling instead now since we’re already running an event loop out of necessity for the viewer)

• memory= keyword for renderables (attempting some kind of support for processing-style live-coded animations)
• fvar_<x> generic style for addressing sorted variable font axes
• x key for xray mode
• g key for grid mode
• p key to print renderable content

• support for platform-specific config files, .coldtype.mac.py, .coldtype.win.py, .coldtype.lin.py
• minor Blender improvements for 3D workflow

• C as valid alias for CX on xalign

• filterContours copy before modify
• Orphan-deletion in Blender

• bake=True for a @b3d_animation

• Spelling mistakes [h/t @HaydenBL]

• Tons of experimental additional functionality for more direct-style scripting of blender and forthcoming coldtype-based blender typography addon (all in fluent.py, with some supporting tweaks in other coldtyper.blender infrastructure)

• New transparency background when bg not specified
• render_bg now defaults to True, since that seems to be the most common use-case
• ufo2ft in [blender] optional requirements
• simple gifski wrapper importable from coldtyper.renderable.animation

• Better error message when trying to "release" via ffmpeg but no files have been rendered

• New arg round_result on SkiaImage.align, to fix jaggy image aligning; defaults to True but is disableable

• glyph_to_uni in packaged mode

• Runon.attach

• Explicit include of ufoLib2 for blender

• P.spread as horizontal-only counterpart to P.stack (paired with P.track and P.lead respectively, funny that they rhyme oppositely whoops)

• Default "." in ALL_FONT_DIRS for linux (so colab notebooks search in their uploaded files by default)

• Easeable.ec as easing-cumulative (to help with partial rotations, as in the new truchet animation examples, and examples/animations/ec.py)

• P.gridlayer, Runon.mapvch, Runon.mapvrc

• .up as canonical form of .ups
• Argument-less boolean operation methods for plural P
• Automatic _-prefixed versions of all P methods, to get clojure-style "phrase"-commenting
• VERSIONS= support for macro-like reversioning of a single animation
• Font.LibraryFind and Font.LibraryList to search font registry (mac-only, windows is excruciatingly difficult)
• Font.names to get style and family name of font via fontTools

• Mondrian -> Scaffold
• th & tv (true-horizontal & true-vertical) have been renamed to potential confusion (since th could be taken to mean true-height) — these are now tx and ty respectively

• The Blender integration now inlines your local venv into Blender, meaning you no longer need to install any python packages into Blender's embedded python.

• -rar (--render-and-release) command-line option to render-and-release(-and-then-quit)

• Scaffold.cssgrid now supports arbitrary regex keys in a dictionary arg for targeting multiple children at once (shown in test_scaffold.py)

• Runon.path and Runon.match (taken from Scaffold) as new generic features, to regex-match on nested/slashed tags (i.e. paths)

• .ufo font-reading on Windows

• Font issue with coldtype demo

• b3denv requirement, to help get default blender app path

• b3denv assumes Blender exists, which is wrong

• P.to_code (for a Goodhertz project that used the legacy DATPen(s).to_code)

• Experimental support for reading control changes (cc messages) from midi files, via MidiTimeline.ci method

• CycleVersionForward/CycleVersionBackward
• Support for _version.py-style sidecar versioning
• Support for special __initials__ function to allow setting state from source file

• Rect.contains/Rect.__contains__/in operator for Rect
• E and W supported on pair_to_edges
• < as parent ref in Scaffold.find
• Support vert as feature (without needing to specify features=)
• RestartCount concept in renderer
• Font.Fontmake for full font compilation to a tmp file

• coldtype.fx.skia.freeze for in-memory "freezing" of vectors (to avoid recalculation)
• Runon.collapseonce for shallow collapsing

• Support for skia-python 87.6 on python3.12

• Fix for >= m87 skia-python with glfw gl-version setting (https://www.glfw.org/faq#macos / skia-python/skia-python#214)

• Support for custom global hotkeys via custom_hotkey function in source files

• High quality filter support for skia > m87

• Spec <=0.4.2 for python-bidi since 0.5.0 is beefed

• use_skia_pathops_draw=False kwarg override for P.removeOverlap to make sure we don't get all-off-curve+None quadratics in situations where we don't know how to convert that to cubics (i.e. in Blender)

• Rect.fit_aspect for easily getting an aspect inscribed by a rect
• version lock on python-bidi

Huge update, attempting to future proof things

• External dependency on coldtype/fontgoggles fork (instead of out-of-date inlined fontgoggles fork)

• Gonna be honest — fixed lots of stuff, should’ve been writing down what I was fixing!

• Make sure coldtype.drawbot does not require skia-python (via incorrect import)
• try/except for filmjitter in coldtype.raster
• Don’t enable audio if audio can’t be enabled (print instructions on enabling audio instead)

• Font.instances to get variable font instance information
• coldtype instances font=<font-search> tool
• ººBLENDERINGºº variable to quickly know if your code is running in blender or as a blender-renderer
• P.trim_start and P.trim_end to quickly drop points from either end of a curve

• P.boxCurveTo factor= keyword now expects float, not int

• Updated coldtype-fontgoggles to latest to avoid Windows thinking it could do objc

• Experimental support for limited keyboard layout remapping via command line -kl argument

• ViewerSoloFirst and ViewerSoloLast shortcuts

• VIEWER_SOLO is now a config option, not a one-off cli arg in renderer

• set_709 on animation.export/FFMPEGExport (so you can use older ffmpeg releases to export animations)

• better support for custom output with ct viewseq
• experimental support for Theme class to set multiple color styles from a single object

• blender venv-inlining now look for a "src" directory if it exists (to match new pyproject.toml-enforced directory structure)

• base dependencies for coldtype (i.e. coldtype installed without any extra) no longer support "extended" font formats (woff, ufo, etc.), though [viewer] extra does still provide support for these; mido requirement has also been moved out of base into viewer; the point of this is to reduce the complexity of a "minimal" coldtype installation (i.e. when embedded as a backend service in another python application or a Blender extension, e.g.)

• refinements to Coldtype 2D panel in Blender for timeline workflow

• ability to set workarea in coldtype 2d panel (blender)
• memory bug in harfbuzz bounding box calculation by downgrading to <0.47

• Update to b3denv for Blender 5 compatibility

• Use showinfilemanager for cross-platform showing-in-"finder"

• demoblender in addition to to demo for uv run coldtype demoblender -p b3dlo

• Blender 5 fcurves utility

• coldtype is now a metapackage that wraps coldtype-core, meaning "coldtype[viewer]" is no longer necessary, you can just do uv add coldtype or uvx coldtype <source-file>.py and it should work

• Soundfiles are now opened with "r" instead of "r+" which I think was totally extraneous (h/t #185)

• < and > support for Rect based on combo of w and h
• Font.metrics for quickly-accessing somewhat normalized font metrics data
• chars tool

• Moved source for glyphs.py to tools (as a new tools directory)
