The latest stable version of DMDirc is 0.8.1. DMDirc is available to download as both a platform-specific installer and a platform independent jar file:
For Windows Vista, 7 and 8
For Debian, Ubuntu, etc
For Red Hat, Fedora, etc
For Mac OS X
For advanced users, on any platform that supports Java
These are the unstable versions of DMDirc, we have started a complete rewrite, so are a bit light on features at the moment, but hope this will serve as an early preview and be usable for basic day-to-day IRCing. Please raise us an issue if you have a problem or feature request (or 👍 an existing issue), or join us in #DMDirc on freenode to chat about the project.
Thanks for trying DMDirc!
The installers below are all created with install4j - a multi-platform installer builder.
