Subject: Non trivial features changes in 1.7.2 via CVS

-----BEGIN PGP SIGNED MESSAGE-----

If you are tracking the cvs version of ruby1.7.2 there has been a 
change in behaviour that affects many libraries. You'll get this
warning

../rmail/parser.rb:104: warning: string pattern instead of regexp;
metacharacters no longer effective

- - Generally, you can fix it by changing code from 
from a quoted string to a regexp. Sometimes however
the warning is a false positive. My understanding 
was that metacharacters only worked if the string
was a "single char". You will get this warning for
strings that are multi-char but contain a \. 


- - The biggest problem I've run into so far is that StringBase in
rubicon seems pretty broken and my simple-minded patches don't
fix it.

- - Booker C. Bense
