[typo] New rewrite rule required?

[Boris]

Hi,

I'm upgrading to Typo 2.6.0 and having some problems with the theme. It 
seems I need a new rewrite rule. I'm under IIS, so my current rewrite 
rule is:

[ISAPI_Rewrite]
RepeatLimit 0
RewriteRule ^(/[^.]*)feed.xml$ /dispatch.fcgi?$1 [L]
RewriteRule ^(/[^.]*)$ /dispatch.fcgi?$1 [L]

For the previous - themeless - typo this worked fine. Any ideas what is 
required?

TIA, Boris
