CDash v4.0.0 available

The release of CDash 4.0 marks the start of a new era for CDash. This release adds several new features including a brand new user invitation and membership system, GraphQL fields for access to instrumentation data, more granular XML validation configuration options, and customizable OAuth2 button text. This release also contains numerous bug fixes, performance improvements, maintenance changes, and dependency updates.

The most impactful change in 4.0 is the removal of support for MySQL. This change will allow CDash to take advantage of PostgreSQL-specific functionality in the future for better performance. See the release notes for migration instructions. 4.0 also removes several obsolete features and configuration options.
