Unison is no longer under active development as a research project. (Our research efforts in this area are now focused on a follow-on project called Harmony—more details are available on the Harmony home page.) At this point, there is no one whose job it is to maintain Unison, fix bugs, or answer questions.

However, the original developers are all still using Unison daily. It will continue to be maintained and supported for the foreseeable future, and we will occasionally release new versions with bug fixes, small improvements, and contributed patches.

Reports of bugs affecting correctness or safety are of interest to many people and will generally get high priority. Other bug reports will be looked at as time permits. Bugs should be reported to the unison-users@yahoogroups.com mailing list.

Feature requests are welcome, but will probably just be added to the ever-growing todo list. They should also be sent to unison-users@yahoogroups.com.

Patches are even more welcome. They should be sent to unison-hackers@lists.seas.upenn.edu. Since safety and robustness are Unison's most important properties, patches will be held to high standards of clear design and clean coding; feel free to ask for advice and feedback on unison-hackers. If you want to contribute to Unison, start by downloading the developer tarball from the download page. For some details on how the code is organized, etc., see the file CONTRIB.
