Every version, and what it changed for you.

Your agent can now trace who wrote any line of a federated repository and why, search a whole kernel-sized checkout, and publish a one-line change without resending the tree.

Before you upgrade — Update, then reopen your agent window so it starts the new version. Your existing indexes are kept; run chi index once on a very large repository so its first search is instant.

• NewNew agent tools for a federated workspace: federation_history names the commits, pull requests and tickets behind any lines of a member file, federation_read returns a file’s lines from the server, and federation_workspace, federation_diff and federation_lineage show each member’s branch and commit, what changed between two states and the work behind a commit — all without a checkout.
• NewOne read policy for every agent tool: paths it must never serve and secret shapes it redacts, set by the workspace, the registry and a .chipolicy.json in the repository, with SCIM groups from your identity provider.
• Newchi pilot report measures rework, reverts and review time of agent pull requests, with and without Archis, computed on your machine.
• ImprovedThe first search after chi index on a repository the size of the Linux kernel takes under 3 seconds instead of a minute and a half, and federated search reads every file that can match in a large checkout instead of stopping at a budget.
• Fixedchi repo publish sends only what the server lacks: a one-line change in the kernel sends six objects instead of two thousand. A new branch’s first sync counts only what changed from its base, and publishing a shallow mirror no longer takes minutes.
• FixedFederation fixes: a shallow clone is refused instead of getting a random identity, chi repo attach registers each repository’s real default branch, the CLI redacts credentials as the agent tools do, federation commands honour --json, and project_overview no longer runs out of memory on a kernel-sized index.
