Release Version 3.24.1#
Git#
The source repository is hosted at gitlab.com and uses the git version control system. The development process follows the methodology used by PETSc, with two integration branches (main and release), together with various feature branches. One can expect SLEPc’s release branch to be synchronized with PETSc’s release branch, and similarly for main.
In order to get the release version of SLEPc, you need to clone the repository indicating release as the branch name:
$ git clone -b release https://gitlab.com/slepc/slepc
At a later time, the repository can be refreshed simply by:
$ git pull
The release branch tracks the latest release version, including all the patches. It is also possible to check out a specific version with the tag name, for instance:
$ git checkout v3.24.1
