Hi all, I'm happy to announce the first release of packdeps[1]. This is a library and executable containing the same functionality as the original packdeps website[2], namely letting you know when your version bounds exclude the use of the newest version of a library available. While the website is very useful for keeping you up-to-date on your already released packages, it does not help you during the development phase, or for packages not released on Hackage. The executable (packdeps) should be a good fit here. Its usage is very simple: simply pass it a list of cabal files, and it will check each one of them against your 00-index.tar file. (In other words, make sure to run a cabal update before relying on its results too much.) The library, frankly, is a mess: the naming is bad, the performance tradeoffs were chosen for a long-running web application instead of a short-lived console app, and it eats a baby panda each time you run it. I'm more than happy to accept patches on this. Nonetheless, I'm not aware of any bugs in the code, and I think it will be generally useful in its current state.
