Re: upgrade from version 5.0.45
Depending on the seriousness of your environment you can read the changelogs and upgrade if you don't see any showstoppers. I have hardly ever seen any problems with minor version upgrades of mysql. Of course what Rob says is true, and it is a good idea to test things out in a test environment first. But I know many environment where it is okay to just run the upgrade, as long as it is a minor version upgrade. I guess it depends on the type of production environment you are running in. be careful though!

Re: upgrade from version 5.0.45
Be aware that if it is an unpatched version of 5.0.77, then there is a bug related to name_const (http://bugs.mysql.com/bug.php?id=42014) that can cause serious problems (infinite server crashes if it happens in a replication thread). Redhat/CentOS have applied the patch, but other sources might still have that bug.
