+flux-core version 0.13.0 - 2019-10-01
+-------------------------------------
+
+## Summary:
+
+This version of flux-core enhances the new execution system to near full
+functionality, including new tools for job submission, better MPI support,
+task and GPU affinity options, and flexible job output handling including
+redirection to bypass the KVS. A powerful shell plugin infrastructure allows
+execution features to be selectively enabled by users.
+
+See flux-mini(1) for more info on the new job submission interface.
+
+Some deficiencies present in this release:
+
+ * flux job list doesn't show inactive jobs
+ * no per-task output redirection
+ * output is space-inefficient in KVS (base64 encoding, one commit per line)
+ * no stdin redirection
+ * need better shell task cleanup and early task exit detection
+ * no debugger support (MPIR)
+
