Infracost v0.9.17 introduces several new features, including an integration with Atlantis, a native Azure DevOps extension, and the ability to set cost policies using Open Policy Agent, Sentinel, and Conftest. With the Atlantis integration, users can post separate pull request comments and upgrade Infracost independently using Docker images, while the Azure DevOps extension now available in the Azure Marketplace offers composable JavaScript tasks and a new output format for pipelines. The update also includes a new Infracost comment command that posts cost estimates to various version control systems, with Bitbucket support coming soon. The release highlights the development of proactive cloud cost policies and celebrates community achievements such as reaching 5000 GitHub stars and contributions from global users, showcasing the growing popularity and usability of Infracost across different platforms and regions. The team, now distributed across multiple countries, is organizing a community call to engage users and share product updates.
