* update on potential codes to be included in next release, from minutes [RH]

** Baikal ETK (Zach, Helvi)

    No Zach.

** Illinois GRDMH (Zach, Roland)

    No Zach.

** Presync (Steve, Roland)

    Roland and Steve fixing, just warnings now. One ticket is blocker (#2348) and Roland has the fix, some warnings left. 
Steve working on it.  Might have to back out of McLachlan code, so it may not have presync.

* timeline of coming release [RH]

    Keep the same timeline, release same.  Could move feature freeze a little later if we want, if folks can work on them---
with APS meeting not in person.

* trivial or minor bugs tagged for next release, all bugs of severity major or worse (should be definition be fixed before the release)

    Roland and Steve on the presync ones.  Otherwise machine defs for Simfactory.

* other open tickets flagged for next release

    No new ones.

* gallery testing: tasks

** volunteers needed, please volunteer (someone)  [RH]

    Gallery examples ready and updated by April 30th, but a good idea to test run them before the
feature freeze (Apr 9).  After the code is frozen should be re-run.

*** TOV: Brock Brendal (UIUC)

*** BNS: Shawn Rosofsky (UIUC)

*** BBH: TBD     Maybe one of Zach's students.

*** Poisson: TBD   Bill G and group (Vanderbilt)

*** Multipatch scalar wave: TBD

Tkt no. 2350 about units.  Hydro units are conventional M=Msol, G=1, c=1.  Maria: going from conventional units
to code units?  Roland: it uses the conventional units.  Magnetic field is a mess, different choices have little difference.
Roland and Maria: is it writing down how to do the conversion---look up HydroBase CCL and that it appears in the
documentation.  And give an example.  Baumgarte and Shapiro's NumRel book has in appendix I - "Binary black hole
puncture simulations as test problems"---note in the captions to Table I.1 and I.2, p. 643, they say for x,P "where 1 code unit =
1.011 M" !
Cactus agrees to map 1 to 0.98 (?).

Roland: Should HydroBase output a banner with units?  Maybe, but it would get lost in the outputs.
