python-dateutil will be updated to version 2.x and there may be changes that affect this package. If python-proteus will work with the newer python-dateutil, you can safely close this bug. If python-proteus really does require python-dateutil 1.5, please use Requires: python-dateutil15 for Fedora versions of the package until it can be updated.
python-proteus is using only dateutil.relativedelta() . relativedelta appears to have had mostly code cleanup and syntactic changes for py2/py3 compatibility and nothing jumps out that would cause a compatibility issue for the way proteus uses the module. I don't have a tryton setup to test here, but: - Debian is providing python-dateutil-2.2 as a dependency of proteus in a comparable release, https://packages.debian.org/unstable/main/tryton-proteus - OpenSUSE's proteus package has Requres: python-dateutil; they are shipping 2.1 currently. They also provide a python-dateutil1 backwards compatibility package which isn't being used. - Ubuntu has python-dateutil as a dependency, they ship a newer version of proteus but still use python-dateutil-1.5 It seems reasonable to infer that using a newer python-dateutil will have no impact, as there are distributions shipping presumably functional packages of the 3.x series with both options. Additionally, proteus/pyson.py from Fedora's 2.6.1 package differs from upstream latest 3.4.1 only in a few extra tab indents. It's probably a good opportunity to catch up with upstream, but I don't foresee any issues relating to the dateutil change.
