Changelog for BenchExec 1.21
# BenchExec Changelog
+## BenchExec 1.21
+
+This release contains only a few bug fixes:
+
+- Forwarding signals to the benchmarked process (and thus, stopping runs via Ctrl+C),
+ was broken on Python 2.
+- If the freezer cgroup was available but mounted in a separate hierarchy,
+ it was not used reliably as protection against fork bombs when killing processes.
+- Since BenchExec 1.19, an exception would occur if a non-existing command
+ was started in container mode.
+- Since BenchExec 1.19, copying output files from a container would occur
+ while subprocesses are still running and would be counted towards the
+ walltime limit. This is fixed, although subprocesses will still be running
+ if the freezer cgroup is not available (cf. #433).
