+### Fixed
+
+- Fixed debug and crash logs to use the configured TUI log directory, including `PI_CODING_AGENT_DIR`, instead of always writing under `~/.pi/agent` ([#6958](https://github.com/earendil-works/pi/pull/6958) by [@davidbrai](https://github.com/davidbrai)).
+- Fixed narrow terminals crashing when the editor's bottom scroll indicator exceeded the terminal width ([#7015](https://github.com/earendil-works/pi/pull/7015) by [@christianklotz](https://github.com/christianklotz)).
