Patches/Sources
We do two builds, ourdelta (standard) and ourdelta-sail (bleeding edge) where the latter contains newer patches that may not (yet) be stable. The dN indicator (e.g., d7) shows from which patchset build the feature is included.
If you see a certain patch not yet available for a version of MySQL, that means you have an opportunity to contribute: you port it, we build it! See the OurDelta project on Launchpad, where you can also find the individual patches and other support files we use. Everything we do is all open and public. You can join the OurDelta-developers team which also has a mailing list, and bug tracking.
We provide proper repositories so you can simply add us to your favourite package manager! If you need to build from source (for instance, for a platform we don’t handle), we also provide source tarballs incorporating our patches (we generate this once per build and feed it into the build systems). The repositories also contain source packages wrapped in the format appropriate for each distro.
