Hi, I've taken advantage of the new travis-ci cron job feature [1] to set up daily builds of numpy manylinux and OSX wheels for the current trunk, uploading to: https://7933911d6844c6c53a7d-47bd50c35cd79bd838daf386af554a83.ssl.cf2.rackcd... The numpy build process already builds Ubuntu Precise numpy wheels for the current trunk, available at [2], but the cron-job manylinux wheels have the following advantages: * they are built the same way as our usual pypi wheels, using openblas, and so will be closer to the eventual numpy distributed wheel; * manylinux wheels will install on all the travis-ci containers, not just the Precise container; * manylinux wheels don't need any extra packages installed by apt, because they are self-contained. There's an example of use at https://github.com/matthew-brett/nibabel/blob/use-pre/.travis.yml#L23 Cheers, Matthew [1] https://docs.travis-ci.com/user/cron-jobs [2] https://f66d8a5767b134cb96d3-4ffdece11fd3f72855e4665bc61c7445.ssl.cf2.rackcd...
