 # Changelog
 
+## Pending
+
+
+## 2026-05-10 - 3.5.0
+
+### Features
+
+- Add inherited terminal stdio support to `execSpawn` for trusted interactive CLIs.
+
+## 2026-05-09 - 3.4.0 - feat(smartshell)
+add cwd-aware execution options, structured strict-mode errors, and safer process tree termination
+
+- adds cwd and env runtime options across exec, spawn, interactive, wait-for-line, and PTY execution APIs
+- introduces SmartshellError with exit code, signal, stdout, stderr, and combined result details for strict-mode failures
+- terminates timed-out commands via process tree killing to prevent detached child processes from continuing after timeout
+
 ## 2026-03-15 - 3.3.8 - fix(repo)
 remove obsolete Serena project configuration files
