Changelog regigate

A note about regigate version numbers

In January 2017 we technically split the regigate product completely from the regify provider. But, as the regigate appliance is still based on the same core software than the regify provider appliance, the regigate versions are still mostly the same than the corresponding regify provider versions.

As the new regigate deployment started in January 2017, the initial version for this list was V4.0.9 (bottom of this page).
