Evolving deployments in Bitbucket Pipelines: Concurrency Groups and Environments

Bitbucket Cloud introduces two new features for Pipelines: Concurrency Groups and Environments. Concurrency Groups replace deployment locks with a more flexible system that manages step execution order using first-in-first-out queuing. Environments decouple environment variables and permissions from the full Deployments framework, allowing multiple steps to run concurrently while sharing the same environment settings. These features provide more granular control over CI/CD workflows and represent the first step in breaking down the monolithic Deployments structure into modular components.
