This is an old release. You should use the latest version instead!
SMAPI 3.15.1 mainly fixes lag for some players, fixes smapi-internal/config.user.json overrides not applied after 3.14.0, fixes compatibility with PyTK image scaling, adds the current version number to update alerts, and (for mod authors) loads the FluentHttpClient package.
Requires Stardew Valley 1.5.6 or later on Linux/macOS/Windows.
