[yt-dev] 2.5 release

Mon Dec 3 10:39:52 PST 2012

Hi all,

Enzo 2.2 is out, so I think we should talk about this again and aim
for a release sometime before the end of the calendar year.  We have a
few outstanding bugs that should be addressed:

https://bitbucket.org/yt_analysis/yt/issues?status=new&status=open&milestone=2.5

I've been curating and culling the bugs for this release.  Most of the
remaining ones are:

 * Documentation related.  The burden mostly falls on me for these items.
 * Various Rockstar items: Stephen, Chris and I are actively working
on finalizing this.
 * A few that have languished for months or years, bumped from version
to version.  I think we should either re-assign these to interested
parties or close them as WONTFIX.
 * Making yt "pip" installable.  I have to test this and probably
won't get to it until later this week.

Please look at the list and either fill out new bugs targeting version
& milestone 2.5 for things you think should block, add/remove yourself
from bugs, or mark bugs as closed for whatever reason.

We also need to get people from FLASH, Boxlib (Nyx, Orion) and Enzo to
contribute tests and data for their codes.  The model for this,
specifically, would be the yt/frontends/enzo/tests/ directory, which
includes Enzo tests.  We *need* this for FLASH, Orion and Nyx.

There are a few things that I think we should discuss.  A long time
ago we talked about the major feature of 2.5 being the profile
plotter, which is the last remaining roadblock for PlotCollections.  I
will start a new discussion about that, which will lead to a YTEP.

-Matt
