- ET_2013_05 schedule Apr 08: No new major additions to the ET until unfreeze This means: after this phone call nothing big (like a new thorn) will be added to the Einstein Toolkit before the next release. May 01: feature freeze of /trunk, extensive testing begins (test-suites on all relevant machines) May 10: release branches are created trunk unfrozen again release-branch code in only-important-bugs-freeze bug-fixing primarily in release branch May 21: complete freeze, to prepare tar-balls, add tags ect. May 23: target release date (or earlier if all bugs are fixed)

ET release:

* no more major additions to the ET * slow down development and concentrate on documentation/fixes * all commits must be explicitly approved by release manager (Frank) * Frank will manage the release milestones

Error reports by Vassili:

* managed to fixed problem * had to switch back to vertex centered grid from cell centering ** will file bug report ** failures were present already outside of AH ** non-conservation of angular momentum when using reconstruct_Wv in cell centered grid ** will try TOV collapse in cell centered case * cure spacetime crashes by resetting to atmosphere when lapse is small (ie inside the AH)

GRMHD paper:

* was sent out on Monday, will be submitted to arXiv on Thursday * some of the plots will be turned into supplements in CQG and appendices on the arXiv

Yours, Roland
