Aseprite v1.3.18.4 Released

Aseprite v1.3.18.4 lands as a small patch release, but it targets several annoying edge cases that can interrupt pixel-art production. The biggest workflow fix is Snap to Grid now aligning correctly for brushes larger than 1 pixel, which matters for artists and technical artists working with larger stamps or patterned brushes.

Tilemap users get a couple of important corrections: copying and pasting tiles between tilemap layers now works properly, and group layers that contain tilemaps copy/paste correctly as well. Those fixes should reduce friction for teams building layered 2D scenes or tile-based content, especially when moving assets between documents or reorganizing complex layer stacks.

The release also starts grayscale color palettes automatically after loading grayscale PNG files, and extensions can now register .psd as a custom file format. That latter change is useful for plugin authors and pipeline tools, since it gives extensions more control over file handling without forcing the core app to treat every format the same way.

On Linux, the main window’s random un-minimize behavior has been fixed, and the build now includes extra crash-origin tracking changes to help diagnose intermittent failures. For developers shipping art pipelines around Aseprite, this is the kind of maintenance release that quietly removes a few sharp edges without changing the overall workflow.
