We provide a new release of JDeli every 6 weeks. You can find out when the latest version was released and when the next version is due to be released by looking at the latest release notes.
We also provide a daily jar that is updated every day. The daily jar is a prerelease version and is provided so that our customers can test bug fixes and experiment with new features before the next release.
The daily jar will have passed our internal continuous integration testing, however, we generally recommend against using it for production purposes as it may contain unfinished features or broken behaviour that is liable to change before the next release.
