 For any customization work, base your own branches on one of the stable branches. That should make it easier to maintain compatibility with plugins and future updates, and it locks down all dependencies to the versions used at the time of release. This is not true of the `main` branch, introducing the danger of incompatibilities between future versions of those dependencies, preventing successful builds of OJS/OMP/OPS at that point.
