Hi

We just released v31 as a bugfix release for v30. This includes a
bunch of fixes to issues uncovered by the recent release. All users
are recommended to upgrade!

## CHANGES WITH 31:

* Fix assertion failures in the user accounting, uncovered by the
changes to accounting in v30.

* Fix a memory leak in service-file re-loading, in particular in the
command-line argument handling.

* Fix a set of UBs related to memcpy(3), memset(3), and others, called
with NULL on empty memory areas.
