Version 5.6 of Sun's Explorer data collector has been released, and is available for download from http://sunsolve.sun.com/explorer
(It was actually released a few weeks ago whilst I was on holidays - sorry for the late notification!)
This version includes a total of 25 bug fixes and new features, which are detailed in the Release Notes if you happen to be interested.
Although it's not normally critical to stay on the bleeding edge of Explorer versions, using a relatively current version can assist if you ever need to contact Sun Support - and having it pre-installed can save precious minutes when you do have a problem.
If you've got any comments or suggestions on how we can improve Explorer please let me know by using the "Comment" link below - I'm a member of the Explorer Change Control Board, and we're always open to suggestions on how to improve it.
