Today I returned to a project, that I haven’t used for quite some time. Now I wonder how I should update the tool chain and libraries for this project. I started with doing a ‘stack upgrade’ followed by a ‘stack build’. Stack was updated to a newer version. No libraries had updates. Are these two steps a good way to keep my projects up to date?

If you are managing a project with stack. Just update the resolver field of the stack.yaml to use the latest LTS Haskell, then stack build.
If you don’t use stack to manage a project, update the stack.yaml of the “global project” (e.g. ~/.stack/global-project/stack.yaml).

Update the resolver to latest lts, comment all additional dependencies you’ve previously added, add them as you resolve build problems.

Also, you might want to make use of https://packdeps.haskellers.com/ to watch for dep updates

Consider also hooking all that into Github CI.

Thanks for all your replies.
I did not know about Stackage and the resolver setting. This helps a lot.
