The current release of the work application targets 5.8.1; the next major release is being written to target latest 5.8.x with the defined-or patch (unless it gets delayed, in which case it might go for 5.10.x).

On my development machine I have 5.8.1 as the default perl, but sometimes use latest 5.8.x or bleadperl to test specific features or to avoid specific bugs.
