For those providers asking about quarterly recertification of applications, please take a moment and become acquainted with the application compatibility protections offered by IRIX® 6.5. This is a very powerful mandate that allows an application to be developed under IRIX 6.5.X and be run on any IRIX 6.5.Y, regardless of whether Y > X, Y == X, or Y < X.

Important note if you do live installs of the IRIX quarterly releases
IRIX 6.5.xx Lookahead
- Updated Inst program
New installation features were used starting with IRIX® 6.5.21 that necessitate an updated version of the Inst program. If you plan to install using the miniroot, then you may do so by the usual method. However, if you plan to upgrade by 'live' install and are running IRIX® 6.5.19 or earlier, you must first install patch 5086.
IRIX® 6.5.26 is in development and is planned to release mid-November, 2004.
