Description

This PR removes the compatibility checks for isdefined(Base, :get_extension) since all SciML packages now require Julia v1.10+, where package extensions are built-in.

Changes

  • Removed unnecessary version checks in extension loading code
  • Simplified extension imports by removing conditional logic
  • Cleaned up obsolete compatibility code

Context

As identified in the SciML-wide analysis, all SciML packages have moved to requiring Julia v1.10+ as the minimum version. This makes the compatibility code for checking whether package extensions are available redundant.

The isdefined(Base, :get_extension) checks were used to support Julia v1.9 where extensions were loaded differently. Since we no longer support v1.9, this code can be safely removed.

Testing

  • Package tests pass locally
  • No changes to functionality, only removal of version checks

Since all SciML packages now require Julia v1.10+, we can remove the
compatibility checks for `isdefined(Base, :get_extension)` as package
extensions are available in all supported Julia versions.

This removes unnecessary version checks in extension loading code.

@thazhemadam why is there a v1.6 test here? It's not in the .github actions script 😅 . I'll merge as others passed but, that's definitely odd in the CI setup.

@thazhemadam why is there a v1.6 test here?

This has been fixed now. There was a repository rule defined which required a job with the name "Tests 1.6" to pass, and when there was none, it just perpetually blocked the auto-mergeability. I've removed updated to rule to check for lts instead.
