The major thing added in this release of sparklet is the command prompt, integrated in messages window, trought which you can kick players, change maps, send private messages... Commands start with a slash (/), just like in IRC. Type /help to see list of commands. You can just start typing, there is no need to open message writer explicitly with F2.
Other minor bugs have beed detected and fixed. Featuring also some usuability fixes, you'll notice it ;-)
