You use extras-devel, so you should be a knowledgable power user, you don't need any help. I've already explained what's happening. Normal users, who don't use the dangerous, untested software catalog, are unaffected.
In case anyone is wondering, we've streamlined the installation process, so once you upgrade to this version the next upgrades will be much faster and more robust. People who do clean installs of version 0.4 will see this already. We have updated all the plugins (this means e.g. seeking in MusePack files now works!) and added WebM support (they are indexed and work fine when played back from the file manager too). In order to get WebM, H.264 and Theora video tag support in the browser we'll need to hack up a plugin, but that's only an idea for now.
