What's new in...

SMAPI 3.12.7?

See the SMAPI 3.12 release highlights for details.

SMAPI 3.12 mainly updates to Harmony 2.1, adds more save recovery and error-handling, improves Unicode support in the console window, and prepares for the upcoming Stardew Valley 1.5.5.

Recent patch updates:

  • 3.12.6 adds a friendly error if mistakenly used with Stardew Valley 1.5.5+, reduces load time when scanning/rewriting many mods, drops support for unofficial 64-bit (you can use official 64-bit instead), improves support for 64-bit in the upcoming Stardew Valley 1.5.5, drops asset propagation for Data\Bundles, adds APIs to help mods prepare for Stardew Valley 1.5.5, and fixes translations for temporary content packs, and updates the compatibility list.
  • 3.12.7 mainly adds more logging during startup, simplifies error logging, adds asset propagation for LooseSprites/Giftbox, and improves crossplatform support for JSON models with nullable XNA types.

⚠️ Some macOS players experience a freeze during launch with SMAPI 3.12.6 or later. This seems to be a macOS issue. If you're affected, downgrading to SMAPI 3.12.5 or updating to Stardew Valley 1.5.5 beta fixes it.

Requires Stardew Valley 1.5.4 or later on Linux/macOS/Windows.

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