Changelog¶

1.0.0¶

First public release.

Slot model — one row builds Backdrop, Peg, Group, Composite, Drawing and an effect chain. Every row in the tree is the same object; what differs is which components are ticked.
Details column — the chain each row will build, written in wiring order.
Range column — sequences, single frames, holds and gaps, reported honestly.
Split & Merge — hierarchical and sibling split modes, Merge Selected and Merge Down, with frame-level variants behind their own guard.
Super nodes — one row that expands into a self-contained unit, renamed in one edit.
Tags shown are tags editable — with Show Tags on, the row, the Inspector's Name field and its checkboxes are three views of one state; edit any of them and the other two follow.
Undo/redo across the whole staging tree.

PSD / PSB parsed by OSA itself: groups become branches, layer names become tags, layer masks become mattes, adjustment layers become effect nodes.
Magnet folders are exact — inside a PSD, a folder is a magnet signal only when its name is the magnet (or an alias) and it carries no tags; PROPS/Prop-1=P-D is a Prop-1 drawing inside PROPS, never the folder itself.
Image sequences (PNG, JPG, TIFF, TGA) grouped by the number in the name, with range detection.
SVG written as native Harmony strokes.
TVG copied in as it is.
Harmony templates (.tpl) staged as a single block.
Transform Sync (.anm) and Blender bakes (.pvt) staged as 3D peg hierarchies with per-frame keyframes.
Import modes reduced to the only real choice: Art Layers or Original Bitmap.
Alignment written as Harmony's keyword, never the enum index.
Long assemblies stay in memory — above 100 images OSA clears Harmony's undo history as it goes, and a raster landing on any art layer takes one utransform launch instead of two (measured byte-identical to the two-pass result), so a sequence of 840 drawings launches ~840 processes instead of ~1680.
Checkpoint save (opt-in, in the browser's Settings) — saves the scene every 100 images of a long assembly so Harmony can release the drawings already written. Locked (hover it for why) until the scene has been saved on disk.

Four art layers per drawing, each with its own type and frame count.
Subart layers — several images stacked on one art layer, promoted automatically when the second arrives, flattened in tree order.
Original Bitmap flattening mirrored: the recipe layer composites into the frame.
Post-assemble flatten rewrites the tree into the shape the scene can store, keeping provenance.

Wide Bus layout: masters on the top row, content on the middle row, composites below what they aggregate, five reserved FX slots.
Matryoshka backdrops — nested backdrops measured bottom-up, each sizing from its own content.
Composite modes measured against a Harmony 24 install (three of four entries in the previously shared map were wrong).

Named destinations with aliases, case-insensitive, matched exact / prefix / suffix, longest first.
Generate Magnet Tree and Generate + Assemble.
Magnetize Scene reads an existing Harmony scene back into staging.
Per-magnet generator recipes: every magnet carries its own structure and effect set.

Transparency (node or flat-baked), Cutter, Blending (25 modes), Glow, Blur.
Brightness/Contrast, Hue/Saturation, Levels, Tone, Highlight.
Colour Card and Gradient as holders rather than chain links.
Every effect is a row in one table — a new effect becomes a tag, a menu entry and an Inspector row in one place.

Continuous autosave of the staging tree, per scene, written atomically with one backup generation.
Crash detection, a restore bar that says what came back and what did not, and self-pruning storage.
