Where should the github issue be placed for an outdated homebrew formuae; homebrew's github, or somewhere on the project maintainers' side?
For a formula I've been trying out, cgdb, it seems that in their 0.6.8 release, they fixed a bug that's been affecting my computer. This version has been released as of November 13th of 2014. However, homebrew (from which I installed cgdb) has the 0.6.7 release.
So where should the issue be placed?
As a Homebrew maintainer, I'd be delighted if you could open a pull request against Homebrew to update the package. Nobody has a defined responsibility to keep packages updated, though some projects choose to submit updates to us directly; we depend on user contributions to keep Homebrew current. Here is a guide; I'm happy to walk you through the process if you have any questions. https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/How-To-Open-a-Homebrew-Pull-Request-(and-get-it-merged).md
