solr version in eZ Find stable-2.7 has been updated from 3.5 to 3.6.1.
(see https://github.com/ezsystems/ezfind/commit/06adcd29f5dbaa84c8e11d34cf0aef1847ea0082)

However, the documentation available at http://doc.ez.no/Extensions/eZ-Publish-extensions/eZ-Find/eZ-Find-2.7 does not reflect 3.6 as a supported version.
