Steady 1.3 maintenance, with the Lua API quietly becoming Aseprite's extension point.
Aseprite is deep into a long 1.3.x maintenance line: v1.3.18 landed in July after three betas stretching back to February, followed within the hour by a 1.3.18.1 crash-fix patch and, two weeks later, a one-line 1.3.18.2. The substantive work in 1.3.18 splits three ways — performance (undo/redo now keeps doc::Objects in memory), discoverability (Preferences search, configurable tooltip delay, clearer layer groups in the timeline), and Lua API growth (custom file formats for load and save, eyedropper in app.useTool). By volume, bug fixes dominate: tilemap selection, zoom distortion, crash paths.
Jitter turns its AI effects engine into a packaged panel — and a pricing tier to match.
Jitter is a browser-based motion design tool shipping weekly, and its center of gravity has moved to AI-generated effects. After launching Jitter AI (build custom effects from a prompt) in May, it has consolidated shaders and effects into a dedicated Effects panel and introduced an AI-heavy Ultra pricing tier. Alongside, it keeps expanding the core editor: components, counters, background blur, glass, and displacement shaders.

By volume, bug fixes dominate: tilemap selection, zoom distortion, crash paths.
The cadence is beta → final → patch, with identical fixes backported across the 1.3.17.x and 1.3.18.x branches — several entries here are branch twins carrying the same two or three fixes. The one directional thread is extensibility: the Lua API version moved 39 → 40 and now lets third-party code register sprite load/save formats the core used to own exclusively. Separately, "refactors needed for new layer types" appears across two releases as internal groundwork with no user-visible effect yet.
Expect the 1.3.18.x patch train to keep absorbing crash reports at this pace, with the next feature release cashing in the new-layer-type refactors that have been landing quietly.

Alongside, it keeps expanding the core editor: components, counters, background blur, glass, and displacement shaders.
The direction is clear — grow the effects and shaders library, let AI generate whatever isn't pre-built, and monetize the resulting AI usage through tiered credits. Editor fundamentals such as reusable components, batch export, and timeline UX are maturing in parallel to keep it viable for team workflows. Jitter is positioning as the place where designers both use and generate motion effects without leaving the canvas.
Expect workspace-level components (already flagged as next), a deeper AI effects library, and more usage-based gating as the Ultra tier establishes AI credits as the pricing lever.
