Roundtable

Wiki might go down real soon. Might need to capture.

We need some redesign design workflow for branchy release process

• When we create a VTK-m release, we have a branch for that release (at least until the subsequent release).
• New feature development continues on the main branch
• _Bug fixes_ happen off the release branch
  • Get merged to both the release branch and the master branch
• This in principal should already be supported by GitLab
  • Just create a merge request on a different branch
  • Will need to add support to gitlab-push
    • Ask VTK folks. They might just have a select few to do a special process.
  • Need to check that bot stuff works (CI builds, Do: merge, etc.)

Should think about releasing VTK-m 1.6, 2.0.

Matt working on WarpX highlight.

Rename master branch?

• Need to wait for some changes to git before the transition (for some automated features of repo).
• Can we for a time have a master that mirrors the new default?
  • Don't know, but seems possible. Will have to look into that.
