~hmm.. maybe because in #751 it upgraded to from 3.3.1 to 3.3.3 and maybe on next visit it would then upgrade to 3.4. I think scala-steward first tries to upgrade to latest patch version, then it upgrades to latest minor version and so on. But not 100% sure.~ See answer below.

I have the same assumption. Anyway this pin will be useful for us 😄

Here is the solution: https://github.com/scala-steward-org/scala-steward/blob/ddfdff8d6a9f587f4bc452a6cf10cb76734fbaae/modules/core/src/main/resources/default.scala-steward.conf#L33-L36

updates.ignore = [
   ...

  // No upgrades to non LTS versions
  { groupId = "org.scala-lang", artifactId = "scala3-compiler",     version = { prefix = "3.4." } },
  { groupId = "org.scala-lang", artifactId = "scala3-library",      version = { prefix = "3.4." } },
  { groupId = "org.scala-lang", artifactId = "scala3-library_sjs1", version = { prefix = "3.4." } },

  ...

Cooool! 😄 Don't need to pin LTS in all repos 🥳

We can keep this two pull requests because one day the main branch will become 2.0.x and there we will not want scala to be upgraded anymore. But yes we do not need to add the pins everywhere.
