Version 3.0.13 - 2010/12/10 * fixed visual anomalies with some message window elements when the tool bar is hidden * TAB does no longer focus the send button when the tool bar is hidden. * MUC: strip unneeded trailing white space characters from messages to prevent them from breaking highlight word matching. Version 3.0.12 Nothing. Version 3.0.11 - 2010/11/17 * added database tweak to forcefully shut down MUC. * fixed problem with customized hotkeys triggered by right ALT when they were defined for left ALT. This is a workaround only, because the actual problem is in the core. Version 3.0.10 * no changes Version 3.0.9 - 2010/10/27 * try to strip control and formatting codes from topic text before using it for status bar and info panel. * MUC: delay RTF header creation (workaround for hang on start with some fonts). not really a fix. * MUC: don't always touch clist group's expanded/collapsed on startup Version 3.0.8 - 2010/10/18 * no changes, released with Miranda 0.9.8 Version 3.0.7 - 2010/10/18 ! fix for overlay icon usage in active containers Version 3.0.6 - 2010/10/10 * time zone api updates Version 3.0.5 - 2010/09/20 * modified sound group names to be more obvious ! fixed memory leak in contact cache when a contact is deleted. * metacontact support: propagate outgoing typing notifications to the active subcontact. * slightly improved compatibility with old (version 2) skins. * MUC: make autocomplete-nickname actions undoable. ! fix: possible crash when closing the last tab in a container and this tab was a MUC session. ! removed ancient hardcoded size limit for the container height. This prevented containers to restore at a height lower than 300 pixels. ! fixed an issue which could cause the unattended send feature being un- available, despite the option saying otherwise. ! additonal checks to prevent uncommanded invokation of the container menu bar, when using hotkeys with an ALT modifier. * support 32x32 icons for the ALT-TAB preview on all supported operating systems. ! dragging text from the message log was broken ! MUC: respect the setting for "auto copy on select text" in group chat sessions Version 3.0.3 - 2010/08/28 ! MUC: topic in info panel did not refresh immediately when it was changed * updater support for the version on the addons site. * load system libraries in a safe way. ! fix (MUC): Do not lose input focus after autocomplete did not find a matching nick name when the option to allow TAB in the input area is enabled. Version 3.0.2 - 2010/08/25 * first stable release for 3.0.x. Version 22.214.171.124 - 2010/08/10 * MUC: added code for case-insensitive highlighting of messages containing your own nick name. * MUC: fixed background color for popups (should now use the correct color set for the MUC log background). * added custom warning messages when importing a theme via Customize->Message window skin. * fixed wrong 32 pixel icon in the container options dialog. Now using the message icon (for which we have both 16 and 32 pixel variants). * avoid creating new windows and event notifications on non-message events (e.g. file transfers).
