Buildkite, previously known as Buildbox, has undergone a rebranding to resolve a naming conflict with another software company, and now operates under the new domain buildkite.com. The change, effective immediately, involves a new API hostname at api.buildkite.com, while the old hostname will remain supported for a year. Users will need to log in again for updated cookies, but no immediate changes are required for current build agents, though future updates will transition to the buildkite-agent name. Communication updates have been implemented across Slack, Hipchat, and GitHub commit statuses, aligning with the new brand identity, and users can reach support through a new email or Slack chat room. Invoices, credit card charges, Twitter handles, and system status updates have also been updated to reflect the new branding, while the company continues to develop new features like elastic agents and enhanced notification systems.
