 # Tux-Dock Development Log
 
+## 0.1.2-beta
+
+This release adds signal trapping to prevent state corruption during long-running Docker operations.
+
+### Reliability
+
+- Added SIGINT (Ctrl+C) signal trapping during busy operations to prevent premature exit and socket corruption
+- Added SIGTSTP (Ctrl+Z) signal trapping during busy operations to prevent suspension mid-operation
+- Signals chain to previous handlers when not busy, preserving normal exit and suspend behavior
+- Trap re-installs after terminal I/O restoration cycles to maintain protection through Attach Shell sessions
+- Used SA_RESTART flag to prevent EINTR on blocking socket reads during signal delivery
+
+### TUI
+
+- Added visual feedback in busy modal when signals are trapped
+- Shows "Ctrl+C ignored: operation in progress" when SIGINT is trapped
+- Shows "Ctrl+Z ignored: operation in progress" when SIGTSTP is trapped
+
