Migration Notes: EDG 7.7 to 7.8
-------------------------------

* TopBraid EDG now uses a **strict Content Security Policy** by default. This disables certain JavaScript features for better protection from XSS attacks. Customizations that use these features must be updated, or else a lax policy can be configured. See :ref:`content_security_policy` for details.

* ADS `graph.withDataGraph` and `graph.transaction` now correctly also change the internal shapes graph that is used by the engine, e.g. to compute `sh:values` rules. This may theoretically cause slight changes in the semantics of ADS scripts that use `graph.withDataGraph` or `graph.transaction`, if these scripts relied on the surrounding shape definitions in the inner callback.
