IDA Teams is the evolution of IDA into a new model that lets teams of analysts work together, using a robust client-server architecture paradigm:

We call the server at the center the “Vault Server”. It is the storage area that holds all the files and tracks modifications. This server is the central point for sharing progress across projects.

Every time a contributor publishes his·her changes to the rest of the team through the server, the change is remembered. It then becomes possible to have teams of people working together on the same project, without a risk of losing data, multiple competing "out-of-sync" versions, etc...

In addition to the new Vault Server, we have improved IDA so it can serve as a tool to perform comparisons between different refinements (i.e., "revisions"), of the same .idb file. With this new functionality, anyone can see what changes were introduced at each revision.
