I’m new to Julia, but having great success speeding up what I once did in python. ‘Threads’ might offer additional performance - but, as I understand it, it’s not available in release 1.0 and I must upgrade to 1.5. Will I be doing myself some hidden diservice leaving the ‘stable’ 1.0? Any advice…

1.5 is also a stable version, and I would say the majority of the ecosystem (i.e. the packages) evolves as new versions come out. Furthermore, Julia guarantees nothing will break (until maybe 2.0), so your 1.0 code should run (probably a bit faster/better) on 1.5 without any code changes. So yes, y…

While the core language upgrade should not be breaking, upgrading Julia probably allows to upgrade a lot of external dependencies (there are a lot of cool features in the last Julia releases, therefore it is difficult for package authors to support both the latest releases and 1.0), which may be bre…

I think v1.6 is where you want to be at in the near future (lots of improvements coming it seems), but I’d already switch to v1.5 (1.5 to 1.6 shouldn’t be too hard). Like lungben said packages would probably give you more troubles than Julia itself. I don’t recall all the breaking changes but Bio.j…

It depends on what you need for your work. For me personally, everything that I needed was working with 1.5.3. Switching to 1.6 proved possible for some of my projects, but not for others. 1.6 in particular seems distinctly advantageous: package operations are much quicker. And I can see overall f…

I use a pretty limited set of packages: Primes, DelimitedFiles, Profile, Statistics, BenchmarkTools, Dates, LinearAlgebra, Compat.

If you have an existing codebase, you can install both versions side by side and run tests to check that nothing broke.

Note: 1.0 is Long Term Support (LTS) 1.5 is Stable Both the current Stable and the LTS are supported, in terms of getting bug-fixes made for issues. As is the current nightly 1.7-DEV and anything currently in preparation for release (currently 1.6-DEV). The difference between then is how long t…

Unless you have low/very low risk tolerance, just test on 1.5 and move on. See [image] Proposed release process and schedule Internals & Design Now that we’ve released Julia 1.0 and are close to 1.0.1 and have added some new features and minor changes to the 1…

Thank you - that is very helpful.
