The Unison developers have released new stable and beta releases of Unison. As Karl M pointed out, the compatibility restrictions between versions have been relaxed beginning with version 2.13: two versions of Unison are now compatible iff the first two numbers in their version string are the same, e.g. all versions 2.13.* are mutually compatible. So, the new packages are named unison2.13 and unison2.17.
I have also updated the descriptions of the available Unison packages in each of the unison2.9.1, unison2.9.20, unison2.10.2, and unison2.12.0 packages, and prepared new point releases of each to include that change. Please review the new unison2.13 and unison2.17 packages, and if they're suitable, upload them and also the new releases of the other Unison packages.
