After installing today's patches. I found that the cipher suites, signature algorithms and elliptic curves on Windows 7 were updated. Document is here: Microsoft Security Bulletin MS14-066 - Critical

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko

signature algorithms: SHA512/RSA, SHA512/ECDSA, SHA256/RSA, SHA384/RSA, SHA1/RSA, SHA256/ECDSA, SHA384/ECDSA, SHA1/ECDSA, SHA1/DSA

Elliptic curves: secp521r1 added
