Over the last few weeks we've released a number of small patches and bugfix improving the overall experience with requires.io, to keep on helping you keep track of Python dependencies.
Handling of prereleases
To figure out if a package is
up-to-date, requires.io was using a very simple strategy: take the latest  version available on pypi, and match it against the requirement. If it matched, the requirement was
up-to-date, otherwise it was
This strategy falls short for two edge cases: prereleases and private forks.
requests==dev # Master fetched from GitHub django==220.127.116.11 # A private fork of Django
These edge cases are now correctly handled, and such dependencies are simply flagged
 It was (and still is) a tad more complicated as we distinguish between unstable and stable releases, but this is beyond the scope of this blog post.
Compatible requirements and pull-requests
A lot of projects on GitHub are using requires.io pull-requests. But until now we didn't handle "compatible" requirements correctly.
Such a requirement is now updated to:
Don't forget that you can specify directives in your requirements files to discard updates you don't need. For instance the following requirement would be flagged
up-to-date and not yield any pull-request, despite being `outdated`:
# Outdated bug flagged `up-to-date` django>=1.6,<1.7 # rq.filter:<1.7
