 - Fix API key resolution after model switches by using provider argument ([#691](https://github.com/badlogic/pi-mono/pull/691) by [@joshp123](https://github.com/joshp123))
 - Fixed z.ai thinking/reasoning: thinking toggle now correctly enables/disables thinking for z.ai models ([#688](https://github.com/badlogic/pi-mono/issues/688))
 - Fixed extension loading in compiled Bun binary: extensions with local file imports now work correctly. Updated `@mariozechner/jiti` to v2.6.5 which bundles babel for Bun binary compatibility. ([#681](https://github.com/badlogic/pi-mono/issues/681))
+- Fixed theme loading when installed via mise: fallback to root directory if `theme/` subdirectory doesn't exist (mise flattens tarball structure). ([#681](https://github.com/badlogic/pi-mono/issues/681))
