Patches Explained

UPDATED: 24 march 2008

I have tried to compile a complete, but short, description of all different patch levels and dependencies that exist between them.

This post is only referring to BOXIr2 on the Windows platform and of the updates that where available as of march 2008. Patches for the Unix platform differs slightly. See Fig. 1 below for a complete flowchart of available paths.

This is a maintenance update which has gone through a full test before release.

SPs could, and probably should, be installed in every environment. Read the Release Notes carefully.

SP2 includes MHF1 and CHF13, CHF14, CHF15 and CHF16. Note: SPs, beginning from SP2, will be cumulative with one exception: none of the cumulative SPs will include SP1. SP1 must always be installed first!

Installation of SPs on top of a CHF will overwrite some fixes solved in the CHF.

MHF1 requires SP1 to be installed first.


This update has had a limited amount of testing before release.

CHF/FP should ONLY be installed into a production environment if you have an issue that is only solved by applying the fix.

All CHF requires MHF1 to be installed first. CHF can only be installed on top of SP1; it’s not intended for higher SP environments.
All FP have a number prefix that says which SP it belongs to, e.g. FP 2.1 can only be installed on top of SP2 and FP 3.2 can only be installed on top of SP3. FP can only be installed on top of SP2 or higher; it’s not intended for SP1 environments.

You can install one or many of the CHF/FP independently of each other.

Thanks for explaining this, Oakleaf. I'd been wondering about how this works for a while now.
