A side-by-side editorial comparison of Aseprite and simpleshow — release velocity, themes, recent moves, and the top alternatives to consider.
Aseprite 1.3.18.x stabilizes tilemap editing and macOS performance after a major release
Aseprite is in a maintenance phase following the 1.3.18 release, addressing bugs and edge cases concentrated in tilemap operations, macOS performance (slowing over time), Linux X11 behavior, and Lua API reliability. Multiple patch releases addressed tilemap copy/paste across layers — a feature that shipped in 1.3.18 but needed several iterations to cover all edge cases. The project ships on a tight patch cadence for a solo-team pixel art editor.
simpleshow buries its occasional product news inside a steady marketing blog.
The feed is mostly explainer-video marketing content — multilingual video, training-video buying advice, and now a guide to measuring video ROI. Genuine product news does appear, but rarely and without any signal in the title: the mask frames release in April replaced most static layouts and is the only capability change in the visible window. Everything more recent is educational.

The 1.3.18 series added Preferences search, faster undo/redo, Lua eyedropper support, and a custom file format API — the current patch cycle is stabilizing those additions. Architecture refactors in 1.3.18 for new layer types haven't yet surfaced as user-facing capabilities; that work is foundation for a future release. The .psd custom format support (via extension API) in 1.3.18.4 hints at an expanding extension ecosystem.
v1.3.19 will introduce new layer type functionality — the architecture changes in 1.3.18 are explicitly described as foundation work for new layer types that haven't shipped yet.

Publishing has slowed and shifted toward buyer-justification topics — ROI measurement, software selection criteria — which serve procurement rather than existing users. The product thread that does surface points at AI-assisted creation and conversational video, but it arrives too infrequently to read as a roadmap. Judging this feed means reading past rank 6, since a release can sit months back with a blog-shaped headline.
Expect the marketing cadence to continue and product news to remain occasional and unlabelled. Any next release is most likely to extend the template and style work that mask frames began, though the feed gives little basis for a confident call.
