In previous versions of InterBase a single user license allowed 4 simultaneous connections in versions 5.x, and 3 simultaneous connections in versions 4.x (see "What is the definition of an InterBase User?")
In version 6.x a single user license allows only one simultaneous connection. To stay concurrent with previous versions allowing additional simultaneous connections per user license we have changed the version 6.x license model to allow the additional simultaneous connections similar to previous versions.
If you have purchased a version 6.x license and require a new license certificate to reflect this correction please call Customer Service at 1-800-331-0877. Please have your current license card available to verify purchase.
