Versionshistoria PuTTY

Förändringar v0.63 -> v0.64

Security fix: PuTTY no longer retains the private half of users' keys in memory by mistake after authenticating with them. See private-key-not-wiped-2. (Sorry! We thought we'd fixed that in 0.63, but missed one.)
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.
Command-line and configuration option to specify the expected host key(s).
Defaults change: PuTTY now defaults to SSH-2 only, instead of its previous default of SSH-2 preferred.
Local socket errors in port-forwarded connections are now recorded in the PuTTY Event Log.
Bug fix: repeat key exchanges in the middle of an SSH session now never cause an annoying interactive host key prompt.
Bug fix: reset the bolded-text default setting back to what it used to be. (0.63 set it to something wrong, as a side effect of refactoring.)
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.
Bug fix: IPv6 dynamic port forwardings should work again.

Förändringar v0.60 -> v0.63

fixes four security holes in 0.62 and before: vuln-modmul, vuln-signature-stringlen, vuln-bignum-division-by-zero, private-key-not-wiped. Other than that, there are mostly bug fixes from 0.62 and a few small features.

Förändringar v0.61 Beta -> v0.62 Beta

Security fix: PuTTY no longer retains passwords in memory by mistake.
Bug fix: Pageant now talks to both new-style clients (0.61 and above) and old-style (0.60 and below).
Bug fix: PuTTY no longer prints a spurious "Access denied" message when GSSAPI authentication fails.
Bug fix: PSCP and PSFTP now honour nonstandard port numbers in SSH saved sessions.
Bug fix: Pageant no longer leaks a file handle when an authentication fails.
Bug fix: PuTTYtel no longer crashes when saving a session.
Bug fix: PuTTY now draws underlines under the underlined text instead of sometimes putting them somewhere off to the right.
Bug fix: PuTTY now should not draw VT100 line drawing characters at the wrong vertical offset.

Förändringar v0.60 -> v0.61 Beta

Kerberos/GSSAPI authentication in SSH-2.
Local X11 authorisation support on Windows. (Unix already had it, of course.)
Support for non-fixed-width fonts on Windows.
GTK 2 support on Unix.
Specifying the logical host name independently of the physical network address to connect to.
Crypto and flow control optimisations.
Support for the zlib@openssh.com SSH-2 compression method.
Support for new Windows 7 UI features: Aero resizing and jump lists.
Support for OpenSSH AES-encrypted private key files in PuTTYgen.
Bug fix: handles OpenSSH private keys with primes in either order.
Bug fix: corruption of port forwarding is fixed (we think).
Bug fix: various crashes and hangs when exiting on failure,
Bug fix: hang in the serial back end on Windows.
Bug fix: Windows clipboard is now read asynchronously, in case of deadlock due to the clipboard owner being at the far end of the same PuTTY's network connection (either via X forwarding or via tunnelled rdesktop).
