The Kanex Group has released MacPopUp 2.5, the Mac OS X version of its instant-messaging solution.

Kanex claims it to be "the only full-featured instant messaging local area network (LAN) solution for Mac OS X". It enables Mac users to communicate with other users on any LAN or over the Internet.

MacPopUp 2.5 lets users exchange LAN messages without switching TCP/IP settings. Recipients can be chosen with a single click, messages can be broadcast, and multiple users are supported. Received messages are also printable in the new version. Speech-recognition technology is also supported, and the software will accept 25 speech commands.

A 30-day trial version of MacPopUp 2.5 is available for download. The full version costs $10. Current customers can upgrade for free.
