Pidgin for Windows

Pidgin(以前的GAIM)是一款功能强大支持多个协议的开源即时通讯软件.包 含的IM协议有AIM、Bonjour、Gadu-Gadu、 Groupwise、ICQ、IRC、MSN、QQ、SILC、SIMPLE、Sametime、XMPP、Yahoo! IM、Zephyr等,十分全面.值得一提的是,QQ不再以插件形式支持了,而是直接可以使用了.
libpurple
Fix a crash when removing an account with an unknown protocol id.
Beta support for SSL connections for AIM and ICQ accounts. To enable, check the "Use SSL" option from the Advanced tab when editing your AIM or ICQ account. (Paul Aurich)
Fix a memory leak in SILC. (Luke Petre)
Fix some string handling in the SIMPLE prpl, which fixes some buddy name handling and other issues. (Paul Aurich, Marcus Sundberg)
Implement support for resolving DNS via the SOCKS4 proxy (SOCKS4a).
ICQ
Fix retrieval of status messages from users of ICQ 6.x, Miranda, and other libpurple clients. (Daniel Ljungborg)
Change client ID to match ICQ Basic 14.34.3096. This fixes publishing of buddy icons and available messages.
Properly publish status messages for statuses other than Available. ICQ 6.x users can now see these status messages. (Daniel Ljungborg)
Fix receipt of messages from the mobile client Slick. (David Jedelsky)
MSN
Fix transfer of buddy icons, custom smileys, and files from the latest Windows Live Messenger 9 official client. (Thomas Gibson-Robinson)
Large (multi-part) messages are now correctly re-combined.
Federated/Yahoo! buddies should now stop creating sync issues at every signin. You may need to remove duplicates in the Address Book. See the FAQ for more information. Thanks to Jason Lingohr for lots of debugging and testing.
Messages from Yahoo! buddies are no longer silently dropped.
We now save and use the CacheKey for ABCH SOAP requests.
Don't try to parse Personal Status Messages or Current Media if they don't exist.
Convert from ISO-8859-1 encoding to UTF-8 when no charset is specified on incoming messages. This should fix some issues with messages from older clients.
Force sending the font "Segoe UI" if outgoing formatting doesn't specify a font already.
Queue callbacks when token updates are in progress to prevent two token update attempts from trampling each other.
Fixed a crash on Windows when removing a buddy's alias.
Update the Address Book when buddies' friendly names change. This prevents seeing an outdated alias or not seeing an alias at all for buddies who are offline when you sign in.
Update tokens for FindMembership and ABFindAll SOAP requests.
We no longer try to send empty messages. This could happen when a message contained only formatting and that formatting was not supported on MSN.
Buddies on both the Allow and Block list are now automatically removed from the Allow list. Users with this problem will now no longer receive an ADL 241 error. The problematic buddy should now appear on the buddy list and can be removed or unblocked as desired.
XMPP
Resources using __HOSTNAME__ substitution will now grab only the short hostname instead of the FQDN on systems which put the FQDN in the hostname. (Matěj Cepl)
No longer send a 'to' attribute on an outgoing stanza when we haven't received one. This fixes a registration bug as described in ticket #6635.
Pidgin
Tooltip windows now appear below the mouse cursor. (Kosta Arvanitis)
Tooltip windows now disappear on keypress events. (Kosta Arvanitis)
Tooltip windows no longer linger when scrolling the buddy list. (Kosta Arvanitis)
Finch
Allow rebinding keys to change the focused widget (details in the man-page, look for GntBox::binding)
