There's a _v3.0.0-preview1_ and it would be great to get this through conan (https://github.com/catchorg/Catch2/issues/1823). There are already earlier versions available.
Since the existing recipes provide good guidance, I'm working on a PR.
I don't think that we should start adding preview versions in general.
With the exception for projects which don't do any stable release in years (like premake) or other edge cases, but Catch2 has a regular release schedule
Is there an unstable or beta channel to ship non-release versions? It would be great to get v3 for early adoption through conan, but generally speaking your are right; if there are typically stable releases provided, I'll better wait for stable-v3.
My recipe is ready, so once v3 is finally out I can provide a PR.
Sorry, there is no unstable or beta channel for packages. The index only accepts stable releases to avoid increasing the number of packages and their creation. Take into account that packages uploaded to conan center will not be removed, so we can only upload stable releases. Thanks
Then let's wait for the stable release.
