Changes:
Version 2018.3.2 is a bugfix release for 2018.3.0.

The 2018.3.2 release contains only a small number of fixes, which are
detailed below.

This release fixes two critical issues.

The first is Issue #48038, which is a critical bug that occurs in a
multi-syndic setup where the same job is run multiple times on a minion.

The second issue is #48130. This bug appears in certain setups where the
Master reports a Minion time-out, even though the job is still running
on the Minion.

Both of these issues have been fixed with this release.
