[Maria-discuss] mariadb update through yum repo when new version is available?

Hi All. I use http://yum.mariadb.org/5.5.30/centos6-amd64/ . Current version is 5.5.30. I would like to use the same version on all my mariadb machines so that (for example) the file format of storage engines would be the same (I make frequently rsyncs between servers). Lets assume that a new version 5.5.31 would be available in repo and then an update would be made. Are updates from 5.5.X to 5.5.Y always safe (small changes) or there can be problems/I should always read release info? Best regards, Rafal.
