 # Changelog
 
+## 0.1.69 - 2026-05-05
+
+### Fixed
+
+- Paseo now recovers automatically when an internal daemon process crashes — your agents stay connected instead of getting stuck and you don't have to restart anything.
+- Answering an interactive question from a Claude agent now reaches Claude correctly instead of being dropped. ([#760](https://github.com/getpaseo/paseo/pull/760) by [@somus](https://github.com/somus))
+
+## 0.1.68 - 2026-05-05
+
+### Fixed
+
+- The desktop app no longer fails on first launch after a fresh install.
+
 ## 0.1.67 - 2026-05-03
