Hi folks,
Here are the outstanding issues for releasing 3.3:
https://bitbucket.org/yt_analysis/yt/issues?status=new&status=open&version=…
I'd like to propose, and hold myself accountable to, a feature freeze
for 3.3. I think we should give a pass on *already* open pull
requests, but set up a freeze starting Wednesday for non-bugfix
changes until 3.3 is released, after which the gates can re-open. If
anyone has any strong objections, let's bump it, but I'd like to see
the release go …
[View More]out and not creep too far. (It's already got quite a
lot in it!)
I'm going to start picking out bugs today to get going. Thanks to
Nathan and Cameron for identifying these bugs for the 3.3 release,
which was a non-trivial task.

Dear yt-Developers,
we found today that the UnitSytem in YTEP-0028 has only 4 (MKS: 5) base
units + the angular measure.
This is a bit confusing since the SI unit system has seven base units,
further including mol (amount of substance) and candela (luminous
intensity), which are not available.
Is this intentional?
Best,
Axel

New issue 1229: Cannot set magnetic units to Tesla
https://bitbucket.org/yt_analysis/yt/issues/1229/cannot-set-magnetic-units-…
Nathan Goldbaum:
This is easiest to trigger by applying the following patch to the FLASH frontend:
```

This is a problem for the OpenPMD frontend, see http://lists.spacepope.org/pipermail/yt-dev-spacepope.org/2016-May/006449.h…
