release 0.64, fixing security issues and bugs :

Security fix: PuTTY no longer retains the private half of users' keys
in memory by mistake after authenticating with them. [bsc#920167]
(CVE-2015-2157)

New feature: Support for SSH connection sharing, so that multiple
instances of PuTTY to the same host can share a single SSH connection
instead of all having to log in independently.

Bug fix: IPv6 literals are handled sensibly throughout the suite, if
you enclose them in square brackets to prevent the colons being
mistaken for a :port suffix."
