What's new

See the SMAPI 3.16 release highlights for details.

For players: this adds better DPI awareness, better macOS terminal support, an error message when you have loose mod files in Mods, and exit codes (which tell your OS whether the game quit normally or crashed).

For mod authors: this adds support for implicit assembly dependencies and F#, migrates to the crossplatform .pdb format, and raises deprecation levels. (Reminder for C# authors: make sure your mod code is ready for SMAPI 4.0.0, releasing later this year!)

Patch updates:

  • 3.16.1 updates PyTK compatibility mode for the latest PyTK version, and fixes broken mods sometimes incorrectly listed as duplicate.
  • 3.16.2 fixes a NoSuitableGraphicsDeviceException launch error for some players with compatible GPUs since 3.16.0.

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

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