See the SMAPI 4.0 release highlights for the main changes.

SMAPI 4.0 mainly updates for Stardew Valley 1.6, 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.

Recent patch releases:

• 4.0.8 mainly fixes crashes for some players, and drops support for Harmony 1.x to help reduce Harmony issues. (That should affect very few mods which still work today.)
• 4.0.7 mainly updates for Stardew Valley 1.6.4, and improves installer feedback when invalid game folders are detected.
• 4.0.6 mainly lets mods set a min supported game version, to reduce issues from players who still have old game versions.

Requires Stardew Valley 1.6.4 or later on Linux/macOS/Windows.
