From the 'teaching an old OS new tricks' files:

HP today officially released its latest Unix operating system, with HP-UX 11i v3 Update 4, codenamed Vigilant.

InternetNews.com got a preview of the new release back in March. Vigilant includes enhanced data protection,high-availability and disaster tolerance features.

With the new release, HP has also taken a interesting step forward in how HP-UX customers actually migrate to new releases. Typically, HP-UX was updated by way of a physical media update, but now HP has an online operating system update. HP claims that new online update options can save up to 50 percent of the downtime that might be required to do an update with physical media.

HP updates the HP-UX operating system in the spring and fall of each year.
The last update was October's HP-UX 11iv3 Update 3, with the previous spring update (Update 2) arriving in April 2008.
