The mod loader for Stardew Valley. It works fine with GOG and Steam achievements, it's compatible with Linux/Mac/Windows, you can uninstall it anytime, and there's a friendly community if you need help. It's a cool pufferchick.
What's new in SMAPI 2.11.2?
SMAPI 2.11.2 fixes compatibility with some Linux distros, and fixes an error on Linux/Mac with some custom maps.
For modders: the upcoming SMAPI 3.0 will drop all deprecated APIs (see migration guide). If an affected mod is open-source, you probably have a pull request on GitHub already (and if it's not, consider going open-source). If you need help, feel free to ask!
Requires Stardew Valley 1.3.36 or later on Linux/Mac/Windows.
