Contributions summary:Roland primarily worked on improving the `ec2-plugin` for Jenkins. Their contributions focused on accurately reporting the count of EC2 instances provisioned by the plugin, specifically by implementing a more reliable method for identifying instances managed by the plugin using a tag. This involved modifying the `EC2Cloud` and `SlaveTemplate` classes to use a specific tag (`jenkins_slave_type`) to mark and identify instances launched by the plugin, correcting the count of instances. These changes ensure the plugin correctly identifies and manages EC2 instances.
