I recently realized that the Julia LTS version is now 1.6 rather than 1.0 (Julia v1.7.0 has been released and v1.6 is now LTS). As a package developer, what version of Julia should I be having my tests run on?
Today, I use GitHub actions (workflow yaml), and run tests on:
- The oldest version I support (1.0, which was the LTS when I first upgraded the package to 1.x)
- The most recent stable release (1)
Should I also be specifying 1.6 since that’s the LTS?
I always just do the latest stable plus the earliest reasonable version that people should be using. At this point, I would call that 1.6. For any new packages I write going forward, I will specify a lower bound of 1.6.
For packages I previously developed, I keep the lower bound at whatever it was at the time (not always 1.0, sometimes 1.3 because that release had a number of new things I use).
I am not a power developer though, so perhaps maintainers of more used packages would be more conservative.
