Today we've released Version 9.0.0c of NMIS 9. This is a late beta release: it works pretty well, but isn't quite entirely production ready yet.
It's possible to run NMIS 8 and 9 in parallel on a single system, so experimenting with the next generation of NMIS is quite easy.
The NMIS 9 Release Notes page outlines what is new and different in NMIS 9.
Today we've released version 8.6.6G of NMIS, which introduces one new feature for multi-homed hosts and contains a number of bug fixes and minor improvements.
The release notes page has an overview of what has changed.
NMIS 8.6.6G can be downloaded here.
