## v9.20.0

-   **Feature: Add ECS Docker ID for Fargate**

    Previously, the Ruby agent did not record the Docker ID when running in an AWS ECS Fargate environment. The Docker ID will now be recorded correctly. [PR#3172](https://github.com/newrelic/newrelic-ruby-agent/pull/3172)

-   **Feature: Add NewRelic::Helper.version_satisfied?**

    The agent has a new helper method to simplify version comparison. `NewRelic::Helper.version_satisfied?` accepts three arguments: a left-side version number, the comparison operator as a string, and a right-side version number. Our thanks go to [@kekke-n](https://github.com/kekke-n) for this contribution. [PR#3182](https://github.com/newrelic/newrelic-ruby-agent/pull/3182)

-   **Feature: Add code.stacktrace attribute on datastore spans when duration exceeds configured threshold**

    The agent will now add the `code.stacktrace` attribute to datastore spans when the duration exceeds the configured threshold. The threshold is configured using the `transaction_tracer.stack_trace_threshold` configuration option. [PR#3220](https://github.com/newrelic/newrelic-ruby-agent/pull/3220)

-   **Feature: Consolidate "Unknown" constant values**

    All references to the various capitalization styles for "Unknown" have been consolidated into two constants: `NewRelic::UNKNOWN` and `NewRelic::UNKNOWN_LOWER`. Thank you, [@tsubasa1122](https://github.com/@tsubasa1122), for your contribution! [PR#3185](https://github.com/newrelic/newrelic-ruby-agent/pull/3185)

-   **Bugfix: Fix Brewfile source links**

    Previously, the multiverse README's links to the Brewfile were broken. Our thanks go to [@emmanuel-ferdman](https://github.com/emmanuel-ferdman) for submitting a PR to fix them! [PR#3191](https://github.com/newrelic/newrelic-ruby-agent/pull/3191)

-   **Bugfix: Fix error when using HTTPX 1.5.0**

    The agent previously encountered an error when using the new HTTPX version 1.5.0. This was due to a change in the way HTTPX stores the response. The agent has been updated to handle this change correctly, and no longer encounters an error when using HTTPX 1.5.0. [PR#3203](https://github.com/newrelic/newrelic-ruby-agent/pull/3203)

-   **Bugfix: Bugfixes and improvements to debug level agent logs**

    Improves the information logged at the debug level by the agent when the agent reads in a configuration source. [PR#3221](https://github.com/newrelic/newrelic-ruby-agent/pull/3221)

-   **Bugfix: Fix risk of server-side forgery for Slack workflow script**

    Internally, we keep track of gems that are released using a GitHub actions workflow that posts updates on Slack. [@odaysec] identified a way we could reduce the risk of server-side forgery for this workflow. Thank you! [PR#3184](https://github.com/newrelic/newrelic-ruby-agent/pull/3184)

-   **Bugfix: Replace JSON.load calls with JSON.parse**

    Generally, JSON.parse is seen as safer than JSON.load. Thank you, [@odaysec](https://github.com/odaysec), for bringing this to our attention! [PR#3183](https://github.com/newrelic/newrelic-ruby-agent/pull/3183) [PR#3230](https://github.com/newrelic/newrelic-ruby-agent/pull/3230)
