> Build dependencies. Ability to trigger project-B build when project-A build succeeds

Within a pipeline, you can 'pass' an output of one step as a triggering input to another. Across pipelines, you can use e.g. an S3 resource to save state; the job to be triggered looks at that S3 resource and triggers when it changes.

> Use the same artifact across multiple build stages.

Yep - you can pass the output of one job to be used as the input of another.

> Ability to combine multiple builds together.

Yep - have a look for "fan-in" in the docs.

> An option to promote a build to the next step either manually or automatically.

You can manually trigger steps from the UI; you could also have a resource that triggers a job automatically on some condition.
