Important changes

PICSAR is now on Github

The PICSAR repo has migrated from Bitbucket to Github. Consequently, all users should update the url of the mainstream PICSAR repo, or simply clone PICSAR again from the Github PICSAR repo. The documentation has been updated according to this change.

The main branch is now called development

The master branches of PICSAR, AMReX and WarpX have been deleted or renamed development. While the change in AMReX does not directly affect WarpX (as WarpX uses the development branch of AMReX anyway), changing the WarpX main branch name does affect users. For new users, who cloned WarpX after this release, there is nothing to do. For others, follow these instructions, provided by @ax3l, to update your local WarpX git branch:

git fetch --all  # get all remote updates in
git status   # check that you don't have uncommitted changes, otherwise commit or git stash them before proceeding please
git checkout development  # creates a local development branch from remote
git branch -D master   # removes the local master branch so you don't accidentally check it out again for future developments

For merge updates from mainline on your feature branches, just replace master with development from now on.

Another thing that you can do: assuming your git remote -v shows the ECP-WarpX repo named as mainline:

git remote prune mainline   # remove all fetched branches that are not existent in mainline anymore
git remote set-head mainline -a   # find the new default branch development as mainline/HEAD (that's an alias for the general "latest" of a repo)
