What's new

See the SMAPI 3.14 release highlights for details.

For players, SMAPI 3.14.0 adds case-insensitive file paths on Linux, improved performance in some cases, and various other improvements and fixes.

For mod authors, this is a big update that adds content events, a redesigned content API, improved proxying, nullable reference type annotations, case-insensitive file paths in SMAPI APIs, and more. For C# mod authors, you should review the migration to SMAPI 4.0 guide to make sure your mods are ready for SMAPI 4.0.0 later this year. (You can update mods now, there's no need to wait for the 4.0.0 release.)

Patch release:

  • 3.14.1 improves performance for mods still using the old content API, temporarily disables case-insensitive paths pending a rework, and fixes various issues in 3.14.
  • 3.14.2 re-enables case-insensitive paths on Linux, improves performance, and fixes some mod assets not working correctly since 3.14.0.
  • 3.14.3 further improves performance, fixes an error with some mods using the old content API, and improves asset propagation for player sprites.
  • 3.14.4 improves performance for mods using deprecated APIs, and removes the warning for mods using dynamic (which now works fine on Linux/macOS).

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

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