 [OK] No errors  

Thanks for raising the issue and providing patch, merged and released as 2.0.0

@nikunjkotecha How was the code committed? Normally the commit would show up here. Example: https://www.drupal.org/project/cshs/issues/3111529#comment-13643324

I was actually looking for it myself before fixing and I'm guessing it has something to do with the new release

https://git.drupalcode.org/project/single_language_url_prefix/-/commit/3...

Along with the fixes I updated the version naming as well to match the new convention and released 2.0.x and 2.0.0 and it shows up there but not here.

Yeah, I put a question about it in Slack and @jungle thought it might be the semantic version versus old versioning. I'll try switching this to 2.0.x-dev and see if that makes it show up though maybe it wouldn't do it after the fact actually. Hmm...
