Infracost v0.9.21 introduces several enhancements, including the integration of cost policies into the CLI and pull request comments, which aids DevOps and FinOps teams in avoiding costly mistakes and budget overruns. The update also includes improved parsing of HCL, making the CLI faster and easier to integrate into CI/CD systems while addressing issues reported across AWS, Azure, and Google platforms. Support for new resources has been added, such as AWS Network Firewall and Google VPC Service Network Connections, and the Jenkins and CircleCI integrations have been updated to align with GitHub Actions and GitLab features, with the deprecation of older bash-based integrations. Usability improvements include setting the default log level to "info" in CI/CD and adding new flags for Terraform commands, along with resolving Slack integration issues. The community continues to grow, celebrating 6,000 GitHub stars, with numerous contributors recognized for their efforts in advancing the platform and sharing insights on cost visibility and DevOps tools.
