With the InterBase division at Borland under new management, the company released a proprietary version of InterBase version 6 and then 6.5. Borland released several updates to the open source code before announcing that it would no longer actively develop the open source project. Firebird, an open source fork of the InterBase 6 code, however, remains in active development.

their line of development tool products, including InterBase, Delphi, JBuilder, and other tools, but instead of selling the divisions, Borland spun them out as a subsidiary on 14 November 2006. InterBase, along with IDE tools such as Delphi and JBuilder were included in the new company's product lineup.

requests from independent software vendors (ISVs) to monitor multiple databases simultaneously in self-managed hosted solutions. “A growing number of ISVs are developing hosted solutions that make full use of the award winning ‘Change Views’ feature in InterBase. Server-wide performance monitoring simplifies the management of multiple databases on the same server,” said Stephen Ball, InterBase product manager at Embarcadero.
