New alpha release 1.0-pre4 of the MySQL Master-Master Replication Manager. This release has lots of major fixes and I’m glad to announce first sponsored port of mmm to non-linux platform - it has been ported to Solaris 10. So, here are our changes in this version:

• Startup scripts added/fixed for mmmd_mon and mmmd_agent
• Installation script now requires iproute package to be installed on server.

More information about this software could be found in detailed announce in Peter Zaitsev blog (actually this software was created by me for his company’s client) or at project page. All your questions and suggestions welcomed in …
