ET release
==========

* freeze postponed by a week
* Cottonmouth: some updates, will need to recreated code once more

CapyrX
------

* issues on outer boundary suggest
* desire to produce a waveform
* Steve raised the question whether this means CapyrX should be
  included or no
* Zach argues that the alternative, waiting a year, is quite bad
* Roland mentioned the idea of point release that would include only
  those changes
* this will need spelling out what is actually meant by a "point
  release"
* in the call it was decided to postpone inclusion of CapyrX in
  2026_05, but make an effort to include all infrastructure changes
  to CarpetX.

-------

* Lucas handed review report to Cheng-Hsin
* change requests are dead-code removal, missing license, and similar
  but no actual code changes

* Zach added a single spinning black hole test case

* Zach will remove the offending code bit

BHNS Gallery example
--------------------

Boost
-----

* included, no known issues yet

TwoPuncturesX
-------------

* Steve noticed that TwoPuncturesX has non-trivial modifications
  compared to TwoPunctures
* multiple issues exist with these multiple (3-4) copies of
  TwoPunctures, making keeping them all in sync difficult
* Steve came up with a way of creating a single source 'library'
  version that could support all of these, at least TwoPunctures(X)
  though
