See what's new in SMAPI 4.5 for the main changes.

SMAPI 4.5 lets you configure SMAPI itself in-game, adds automated and attested builds, retires the 'SMAPI for developers' edition, and adds malicious file detection.

Patch releases:

• 4.5.1 fixes an error installing SMAPI 4.5.0 on Linux/macOS, and updates Portuguese translations.

Requires Stardew Valley 1.6.14 or later on Linux/macOS/Windows or Steam Deck.

(⚠️ For macOS players: don't forget to follow the full install guide for macOS to avoid security warnings. Players on Linux or Windows can ignore this.)
