What's new

See the SMAPI 3.17 release highlights for details.

For players: this mainly optimizes performance, adds a separate 'strict mode', and drops the transitional 'raw image loading' option (now always enabled, except when PyTK is installed).

For mod authors: this mainly makes consumer info available when implementing GetApi in a C# mod, updates the mod build package, and words deprecation messages more strongly. (Reminder for C# authors: make sure your mod code is ready for SMAPI 4.0.0, releasing later this year!)

Patch updates:

  • 3.17.1 fixes an installer error when Steam's .vdf library data is missing.
  • 3.17.2 fixes an installer error when Steam's .vdf library uses an older format, and fixes an image patch offset issue.

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

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