As of release R034 we will be providing two archives, the 4.x series based on the
existing GSEOS 7.1 system and a 5.x series based on GSEOS 8.
The goal is to migrate all teams to the 5.x series and to retire the 4.x branch.
Until that point we will provide both the 4.x and 5.x releases in parallel.

version going forward.
While all configuration files can be opened in GSEOS 8 this is not true
for all configuration files going back to 7.1. You can open GSEOS 8 modified
files like screens (with some limitations) and graphs in GSEOS 7.1.
However, we recommend to avoid this and switch over to the new release
as soon as possible.
