[PR#3262](https://github.com/newrelic/newrelic-ruby-agent/pull/3262)

-   **Feature: Deprecation reminder for cross application tracing**

    Cross application tracing has been deprecated since major version 8.0.0 of the Ruby agent. We will remove support for it entirely in version 10.0.0 of the agent. [PR#3288](https://github.com/newrelic/newrelic-ruby-agent/pull/3288)

-   **Feature: Ensure compatibility with Ruby 3.5 change to Method#source_location**

    Updated the agent to correctly parse the return value of Method#source_location, which is changing in Ruby 3.5 from a two-element to a five-element array. This change maintains support for older Ruby versions while adding support for the future release. [PR#3257](https://github.com/newrelic/newrelic-ruby-agent/pull/3257)
