Glad to see 6.1.7 released and thanks to everyone for your hard work. I have it installed and noticed just one minor issue still related to SSL.
I use a subdomain secure.domain.com for SSL and noticed after the upgrade it gave a 404 not found error when accessing https://secure.domain.com/ and all directories. I decided to delete the subdomain and add it again because it appears the subdomain for SSL was no longer recognizing the root directory. I also needed to reassign the IP address for the SSL certificate to get everything working again. I haven't had this problem with previous upgrades so this appears to be a minor bug related to Apache configuration?
