if anyone uses Google Sitemaps and hasn't logged in for a few days, you probably should.
The headers required on the XML files have been changed, so you'll probably see error messages reported. Once you get that sorted, it'll then report any errors in the actual XML files.
All very handy, but some notification would have been nice!
No errors showing for me, they're being downloaded daily from a number of different sites, and I haven't changed anything in the way they are generated.
Not sure why only some people are affected and not others? We've had our sitemaps in their previous format for a fair while, is it possible they updated the schemas a while back and are only now killing the legacy version?
I've been writing a lot of my Google Sitemap files by hand and I haven't noticed any changes.. Like the others, my existing sitemaps are still showing no errors..
