[Mediawiki-l] 1.5 beta3 to 1.5rc1

[Joshua Bass]

I upgraded from 1.4.6 to 1.5b3 and have been developing on that platform for a 
few weeks. Now that 1.5rc1 is out, can I simply overwrite all of the files to 
upgrade?

Also, I had experienced a major bug. When upgrading to 1.5 from 1.4.6 I lost 
the MIME relations to about 1/3 of all my images. I had to reupload them in 
order for thumbnails to generate.
