What is Aseprite?
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.
What is Zeroheight?
Design system documentation making itself the constraint on AI-generated UI
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.

Aseprite
5.0DESIGN
Steady 1.3 maintenance, with the Lua API quietly becoming Aseprite's extension point.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Zeroheight
0.0DESIGN
Design system documentation making itself the constraint on AI-generated UI
◆ Current state
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.
◆ Where it's heading
zeroheight's problem has always been that documentation nobody opens does not govern anything. All three releases attack that from different sides: bring the docs to where people already are (Slack, Teams), let them be asked instead of read (Assistant), and inject them into the tool that generates UI (Figma Make). The last is the most consequential, because it changes documentation from a reference into an input.
◆ Prediction
Expect connectors for further AI generation surfaces beyond Figma Make, since the Figma Make integration establishes the pattern of design system guidance as generation context rather than as a page someone consults.
