`devel` is the main (trunk) branch. All the development (and pull requests) happens against that branch, and it is "cutting edge" \-- Nim built from it has version `0.20.99`.
`version-0-20` branch contains backported (cherry-picked) bugfixes from devel. Currently it is at version `0.20.1`, which will become an official released stable version `0.20.2` and future backported bugfixes will be `0.20.3` until version `0.20.4` is released, and so on. (This is how it works generally; no guarantee that v0.20.4 will happen - v1.0 might be released before that) > For now I will try to make sure our code is compatible to both `devel` and > `version-0-20`. Since Nim v0.20.0 is basically v1.0RC1, the priority should be compatibility with the latest stable version and `version-0-20` branch.
