 Tools can now be registered dynamically through an API. This capability allows the set of available tools on the server to be adjusted based on configuration or environment.
 
-Tools can be registered by injecting `ToolManager` and calling its methods to add, remove, and list the available tools on the server. The full Javadoc for `ToolManager` can be found within the liberty beta in `dev/api/ibm/javadoc/io.openliberty.mcp_1.0-javadoc.zip`.

 Tools can be registered when the application starts through the CDI `Startup` event. See the following example where the `Startup` event is used to register a weather forecast tool only if a `WeatherClient` bean is available.

 == Preview of some Jakarta Data 1.1 M2 capability
 
-Previews some new capability at the Jakarta Data 1.1 Milestone 2 level: `Constraint` subtype parameters for repository methods that constraints to repository `@Find` operations and limited use of `Restriction` with repository `@Find` operations. Also included from the prior beta are: retrieving a subset/projection of entity attributes and the `@Is` annotation.

 Previously, parameter-based `@Find` reposotory methods could filter results only using equality conditions. This limitation has now been removed, allowing additional filtering options to be defined.
