SMAPI 4.5 lets you configure SMAPI itself in-game, improves performance, 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.
- 4.5.2 mainly improves performance, fixes the Linux/macOS installer not saving the color scheme correctly in 4.5.0+, and updates translations for recent changes.
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.)
