+Notable changes in 0.29.3 as compared to 0.29.2
+===============================================
+
+General
+-------
+
+* Newer versions of par2 can process in parallel using multiple
+  threads/cores, and they do so automatically.  This ends up competing
+  with `bup fsck`s own parallelism, enabled by `-j`, in such a way
+  that the command can actually run much *slower* (and be much more
+  expensive) than it would have been with no parallelism at all.
+
+  When appropriate `bup fsck` now disables par2's competing
+  parallelism (via its `-t1` option) to avoid the contention.
+
+Build system
+------------
+
+* test-prune-older should no longer be disturbed by git's automatic
+  background gc.
+
+Thanks to (at least)
