What's new

See the SMAPI 3.15 release highlights for details.

This mainly improves performance, adds an IRawTextureData asset type for mod authors, adds per-mod verbose logging, adds the FluentHttpClient package, updates Harmony + Json.NET + Pintail, and fixes issues.

Patch updates:

  • 3.15.1 mainly fixes lag for some players, fixes smapi-internal/config.user.json overrides not applied after 3.14.0, fixes compatibility with PyTK image scaling, adds the current version number to update alerts, and (for mod authors) loads the FluentHttpClient package.

Requires Stardew Valley 1.5.6 or later on Linux/macOS/Windows.

See the release notes and mod compatibility list for more info.
