This is an old release. You should use the latest version instead!
SMAPI 3.5 mainly prevents more game errors for invalid item data (so you no longer need save editing to remove broken items), adds a new map patching API, adds patch helpers, improves SDate, and improves asset propagation. See the release highlights and Reddit thread.
Requires Stardew Valley 1.4.1 or later on Linux/Mac/Windows.
