KMess 1.0 released.

KMess is finally considered stable and basic-feature-complete, though it's been stabler and more feature-ful than many MSN clients for a while now.

KMess Feature list

MSN Messenger protocol compatibility
Font and font color support, including the ability to force contact messages to appear in a particular font and color.
Full emoticon support, featuring a custom GPLed emoticon set and the ability to use different emoticon themes.
File transfer support, both sending and receiving.
Hotmail support, with new email notifications, the inbox count, and the ability to open Hotmail at the user's inbox or at the composition page.
The ability to disable and hide email information for accounts that don't use Hotmail.
Support for multiple user profiles.
Autologging, either at the setting page for from the commandline (with "kmess --autologin blah@hotmail.com" for example).
A contact list that can organize contacts by group or by online/offline status.
Groups show a count of the contacts online (i.e. "Friends (2/5)")
The user can specify particular contact images and sounds to be displayed when a contact comes online or in a chat.
The user can specify a name for a contact, overriding the contact's specified name.
The user can choose on a contact-by-contact basis whether the user should be notified when a particular contact comes online or goes offline.
KMess can show a contact's MSN profile, and open the MSN search pages.
In addition to the usual user statuses of "Away" and "Busy" and so on, there is the status "Away with Autoreply" that will reply to contact's chat messages with a user-specified away message.
The chat window has been redesigned with a new sidebar (which can be toggled with Ctrl+T) with an emphasis on contact images.
The chat window notifies the user that a contact is typing by "glowing" the contact's image.
Chats can be logged automatically and the chats ordered in subdirectories by day, week, or month, or not ordered at all.
Chats can be configured to show timestamps when contacts send messages.
A "compact" chat format can be used to remove extraneous line breaks and reduce the size of the chat.
The chat window caption in the taskbar alternates between lower and upper case to inform the user of a received message when the window is not on top.
Internationalization support, with translations in: English, Dutch, German, Italian, Portuguese, Spanish, Turkish, Chinese, French, Catalan, Arabic, Korean, Norsk, and Thai
There is now a method, though not absolute, to tell if a contact is blocking you. If a chat is started with a contact that appears offline, you will be informed if the contact is offline or online and blocking you.
