Introducing the Build Pipeline

Buildbox introduces Build Pipelines, which enable users to split builds into smaller steps and run them in parallel across multiple build agents for improved speed. The example demonstrates a pipeline with three steps - rspec, staging-deploy, and staging-smoke - that run sequentially. Once all pass, the pipeline is blocked until manually allowed to continue. Each step has its own set of agents, environment variables, artifact paths, and branch configuration, providing flexibility in pipeline configuration. However, Build Pipelines only work with new agents, requiring users to upgrade if necessary.
