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 2.9.1?
SMAPI 2.9 mainly fixes a number of issues, adds new features for modders, and begins the migration to SMAPI 3.0.
For modders: you can now update your mods for the upcoming SMAPI 3.0, which will release in Q1 2019. 3.0 overhauls SMAPI events so they're much more consistent, powerful, extensible, and discoverable. You can install SMAPI 2.9 'strict mode' to test your mods for compatibility with SMAPI 3.0. If you have questions or need help, feel free to ask!
Requires Stardew Valley 1.3.32 or later on Linux/Mac/Windows.
