I am a lone developer working on many projects simultaneously, and keeping all these bugs in my head has become burdonsome. I've been using some "task" websites to manage my bugs for a while now, and it's been relatively sufficient. However, my current project just exploded in scope and now I need something way more robust. I currently use Mercurial and BitBucket for my version control and repo respectively, so I was hoping someone knew of something that integrated with those. At the very least, I'm looking for a free bug tracking system.
PS: aware of this question but I couldn't find anything with HG integration.
Thanks!
