Zed opens early access for DeltaDB, a version control system that records edits between commits and links them to the agent conversation

Sources: primary, discussion
Summary: Zed opened early access for DeltaDB. It records individual edits between commits and associates them with the agent conversation that produced them, with a virtualized worktree described as the mechanism. Access is early access only, with no general availability date stated.
Why it matters: Virtualizing the worktree is what would make branching mid-agent-run cheap, which is the operation git has no answer for when the unit of work is an agent session rather than a commit.
