Which in of itself FUD...

Read the feature proposal or the release notes...

To install the oracle community mysql from the fedora repos use the package name community-mysql but I would recommend following the 'default' mysql of mariadb... The change was not for no reason...

With regards to your suggestion that would result in 5.6 which is a potential marked change from 5.5 - even more so than mariadb which is why it was kept at 5.5 this release... If you read the relevant threads in -devel you can follow the reasoning...

With regards to the OP no issues and several benefits to have mariadb 5.5 instead of mysql community edition 5.5
