Product Retirement Dates

The following GuardIEn releases have been / will be retired on the dates shown in the table below. The table also shows the highest level of Gen supported by each release. Note that earlier releases are also supported, so for example, GuardIEn 8.7 will also support Gen 6.5, 7.0, 7.5, 7.6, 8.0 and 8.5.

IET will endeavour to answer questions on the retired releases and resolve problems but no new fixes will be provided after the retirement date. To ensure that you are on a supported release and also to ensure maximum compatibility with the current releases of CA Gen, IET strongly recommend an upgrade to the current release.
