described below.
Engineering Test (ET)
An ET is an installable component that contains the files needed to assist developers
when diagnosing a problem. An ET is intended for a limited scope test. An ET can
contain server and/or client files. Apply the ET on the servers or client desktops that
you want to test. If the ET also contains client files, install the ET directly on the client
desktop. The ET does not work with automated updates.

Engineering Special (ES)
An ES is an installable component that addresses a specific bug fix needed by one or
more customers. An ES is cumulative. If two ESes are issued against a base release,
the latest ES contains all the fixes provided in the previous ES. An ES can contain
server and/or client fixes. Always install an ES on the same server as the CAD base
services for automatic updates to work. An ES is tied to a specific version of the base
release and/or Maintenance Release (MR). If the ES contains no fixes for the desktop
clients, automated updates do not run.

Maintenance Release (MR)
An MR contains all patches for all bugs found and fixed since the base release of the
product. An MR is cumulative. If two MRs are issued against a base release, the latest
MR contains all the fixes provided in the previous MR. For example, 8.5(4) contains all
the fixes provided in 8.5(2a). You can update to 8.5(4) from the CAD 8.5 base release
without having to install 8.5(2a).

An MR contains fixes for the CAD base services server and/or client desktops. Always
install the MR on the same server as the CAD base services. CAD uses automated
updates (if enabled) to update desktop clients when you install the MR. If the MR
contains no fixes for the desktop clients, automated updates do not run.

Each MR appears in the Add/Remove Programs window. Uninstalling an MR allows for
rollback to a previous state. If an MR is server side only, the Add/Remove Program title
displays Server only.
