+- Trapping a signal that is not a pseudosignal will now cause a virtual
+  subshell to fork into a real one. This ensures a persistent PID where
+  other processes can signal the subshell (the PID of a virtual subshell may
+  change as other commands cause it to fork), and fixes a bug where a signal
+  could not be correctly or effectively trapped in a subshell if the same
+  signal was also trapped in the main shell environment.

 - The POSIX mode now disables zero-padding of seconds in 'time'/'times' output.
