Tip
This is an old release. You should use the latest version instead!
See the SMAPI 4.0 release highlights for the main changes.
SMAPI 4.0.0 mainly updates for Stardew Valley 1.6.0, improves performance and compatibility rewriting, adds per-mod-folder settings, and removes Error Handler (which is now integrated into the game itself). For mod authors, it mainly adds custom update manifests, adds new render step events, and drops deprecated APIs.
Requires Stardew Valley 1.6.0 or later on Linux/macOS/Windows.
