Hey gang,

Just a heads up for some of you that may not have been around the coders
channel when it happened, but the certificate for the SVN server has been
updated. We are also now using a newer non-MD5 Class 3 Root from CAcert to
avoid a long standing hack that many (in Linux at least) needed in order to
use
subversion over SSL on systems with a newer neon27 GNU TLS library, which
was
patched to not trust MD5 signed certificates.

For those of you that edited your ~/.subversion/servers file to add
"ssl-trust-default-ca = no", you should now be able to remove that line and
use
SVN via SSL/HTTPS normally.

For those wondering, here is a copy of the new fingerprint and related info:
