LTS distros like Ubuntu LTS, RH, CentOS are usually deployed in business and institutional environments where office suite is among the most critical need. Unfortunately in name of stability all these distros grossly overlook the fact that Libreoffice is going through rapid development and transition and every new edition improves compatibility with MS Office files. I am truly surprised with the apathetic attitude of the devs of these so called LTS distros, CentOS till a few months back were shipping with old outdated Open Office, Ubuntu ships with older 3.5, the ppa for libreoffice is a big joke and there is hardly any updates, till now its stuck in the initial and buggy 18.104.22.168 where Arch based distros have the latest 3.6.2, sadly Arch and its derivatives can't be deployed at offices and neither can non LTS Ubuntu. They really need to work in this aspect for Linux to be accepted in a commercial sphere. Sure everyone is looking for stability but then none are looking for obsolescence or compatibility issues either.
