Protege 4.0 Release -- June 16, 2009
Protege 4.0 has been in development in parallel with the Protege 3.x series for approximately 3 years. Initial alpha versions were developed by the CO-ODE team and it is now under active development by CO-ODE, Stanford's Protege team, and several other developers.

What's next?
While Protege 4.0 was under development, the OWL 2 ontology language has been moving through the W3C recommendation process. This process is almost at an end and the specification is stabilizing so that this updated language can soon be used in earnest by the community.
We are excited to provide one of the first tools to support OWL 2. Our intent is to provide a well designed ontology editor as quickly as possible once the OWL 2 ontology language reaches recommendation.
In order to keep Protege 4.0 as stable as possible for users and contributors over the last year, a lot of work has been happening in the background on the OWL API to follow the specification as it changes over time. Some of the modifications to the language have inevitably been backwards incompatible - mostly vocabulary but also some structural changes. We have done our best to keep Protege 4.0 as isolated from these changes as possible and decided to release based on version 2 of the OWL API so that existing plug-ins, user interface, and ontologies are stable and compatible.
During May and June, branched Protege 4.0 and migrated to the newest version of the OWL API (version 3). After the Protege Conference, this branch will become the main development trunk where we plan to continue implementation of new features. There are still likely to be some shifts in the code over the next few months, but we would like developers to have a look and let us know how you think we are doing. In the meantime, all plug-ins from CO-ODE will be migrated to the updated platform and we will use this process to help develop some migration guides for plug-in developers. As a user, if you are desperate to use some of the late entry OWL 2 features that have not made it in to Protege 4.0 (such as keys) and you are good at backing up your work there will shortly be a pre-alpha release available for people to download.
What are the major differences between Protege 3.4 and 4.0?
Protege 3.4 provides support for building frame-based ontologies and is also a robust platform for OWL 1.0 ontologies.
