Please, for existing versions and whenever a new minor version is released under a major version, create a symlink to it with major version name. For example, 3.2 is current stable and there could be 3 -> 3.2, when 3.3 released, 3 -> 3.3 and when 4.0 released, 4 -> 4.0 etc. This gives SysAdmins feasibility of not to change repo files for every minor release.
