Decky Loader 3.3.1 Stops the Plugin Store and Updater From Failing Quietly

The Steam Deck Homebrew team released Decky Loader v3.3.1 on October 26, 2026, at 11:26 PM CT. It’s a stable release, not a prerelease, and it follows v3.3.0. A v3.3.1-pre1 build went out shortly before it.

What changed

From the release notes:

• Updater fix (PR #1000): Decky now allows larger response headers when it downloads its own updates. This was the first contribution from @FlashyReese.
• Plugin store errors (PR #1001): Decky now handles plugin store load failures instead of breaking.
• Translations (#998 and #1002): Two rounds of Weblate translation updates.

The full commit list from v3.3.0 adds two more items:

• Certificate cleanup: A dependency update revokes the eMudhra intermediate CA in certifi, the certificate bundle Decky’s Python backend uses.
• VR branch: A commit titled “pick in some fixes from the vr branch.” The release notes don’t describe those fixes, so I won’t guess at them.

Builds

The release has builds for Linux x86_64 and arm64, Mac, and Windows x64 and arm64 (each Windows build also comes in a no-console version).

Should you update?

It’s a small patch, but it targets the two places where Decky tends to fail without much explanation: updating itself and loading the plugin store. If you’re on v3.3.0, update from Decky’s settings in the Quick Access Menu.
