What are the next steps?

If you have been assigned as a reviewer to this Merge Request, please review this Merge Request with the same scrutiny as any community contribution:

Ensure that the dependencies updated meet our standards:
- Security: Dependencies do not contain malicious code
- Performance: Dependencies do not bloat the application code or prolong CI times unnecessarily
- Stability: Pipelines are passing
Review the changes introduced by the version upgrade. Consider using https://my.diffend.io to compare the two versions in case the updated dependency is either a Ruby Gem or a Node.js package, for example to compare pg_query 2.1.0 and 2.1.4.
Check if bundle install works locally, in the context of GDK.
If tests are passing and you've reviewed the updated dependencies, execute pipelines in the context of the main project

This MR is created from a fork, therefore not all jobs (e.g. Danger) might have been executed. Instead of hitting MWPS right away, you might want to wait until the pipeline you've just triggered finished.

Note: This might not be available in projects, in that case merging right away is an option
Merge away!
