  Download the distribution files
  [here](https://activeviam.jfrog.io/artifactory/activeviam-accelerators-artifacts/cvarc/6.0.0/)

  The distribution files comprise the following zipped artifacts:

  * UI source code.
  * UI build that does not require an installation and can be directly deployed.
  * Source files that can be used to build the application.
  * Maven repository required to build the project and run the tests.

  <Note>
    The Atoti Server 6.1.19 Maven
    repository files have been removed from this zip, so you'll need to download them separately.
    Click [here](https://artifacts.activeviam.com/share/ActivePivot_stable/6.1.19/) to locate them.
  </Note>

  * Offline documentation.

  ### Summary

  * **Java 21**: Java 21 is now required to run Atoti CVA Risk Capital.
  * **Spring Boot 3**: Upgrade to Spring Boot 3.x with Spring Security 6.
  * **Atoti Server 6.1.19**: Upgrade to Atoti Server 6.1.19.
  * **Jakarta EE 10**: Migration from `javax.*` to `jakarta.*` namespace.
  * **OpenTelemetry**: New observability framework replacing Spring Sleuth for distributed tracing.
  * **Tomcat 11**: Upgraded to Tomcat 11.0.6.
  * **What-If 5.0.0-AS6.1**: Upgraded from 2.1.6-AS6.0 with Hibernate-based simulation persistence, JWT authentication for distributed deployments, expanded store coverage, improved error handling and support for simulation branch chaining.
  * **Removal of obsolete DispatcherServlet configuration**: Removed the `dispatcherServletRegistration` bean from `CVARCApplication`, which was a workaround for Spring Boot incompatibilities in previous versions of Atoti Server.
  * **Module restructuring (CVARC-907)**: Renamed Maven modules for cleaner separation of library and configuration concerns. Old `cvarc-starter` is now `cvarc-application`; a new `cvarc-starter` auto-configuration library is introduced. See [migration notes](./migration-guide#module-rename) for the full rename table.
  * **Main class renamed**: `CVAWebApplication` → `CVARCApplication`.
