* 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 https://bitbucket.org/einsteintoolkit/tickets/issues/2348/presync-branch-of-mclachlan-modifies) 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 https://docs.einsteintoolkit.org/et-docs/Release_Details#Schedule_for_ET_2020_04 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 https://bitbucket.org/einsteintoolkit/tickets/issues?kind=bug&priority=minor&priority=trivial&milestone=ET_2020_04&status=new&status=open tagged for next release, all bugs of severity major or worse https://bitbucket.org/einsteintoolkit/tickets/issues?kind=bug&priority=major&priority=blocker&priority=critical&status=new&status=open (should be definition be fixed before the release)
Roland and Steve on the presync ones. Otherwise machine defs for Simfactory.
* other open tickets https://bitbucket.org/einsteintoolkit/tickets/issues?kind=proposal&kind=enhancement&milestone=ET_2020_04&status=open&status=new flagged for next release
No new ones.
* gallery testing: tasks https://bitbucket.org/einsteintoolkit/tickets/issues?kind=task&milestone=ET_2020_04
** 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.

Tkt no. 2350 https://bitbucket.org/einsteintoolkit/tickets/issues/2350/conversion-of-units 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 https://bitbucket.org/einsteintoolkit/einsteinbase/src/master/HydroBase/interface.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.
