I mean how a person choose a bug to start fixing issues reported on github ? Maybe solution is already present in pull request? Especially for 3.18 milestone.
Well you can look at pull requests to see. But if you find an issue you want to fix and someone has made a PR to fix it Github tells you in the comments section that someone submitted a PR
Thanks for info. I will keep an eye on comment section.
And you can view their work etc. forgot to mention that.
