JULESvn5.0 released today. See the JULES TRAC https://code.metoffice.gov.uk/trac/jules for docs and release notes. Toby.
Addition from Doug Clark 1st Nov: If you want to update an older branch to vn5.0, note that there are suggestions as to how best to do that at https://code.metoffice.gov.uk/trac/jules/wiki/MoveBranchesToVn5.0 . The aim of the recipe provided there is to minimise the number of conflicts that arise when merging an older branch (though the extensive changes at vn5.0 mean some conflicts might still have to be resolved).
