Cue 0.2.0

Cue 0.2.0

Breaking changes

Cue 0.2.0 switches the runtime and all frontends to IPC v4. IPC v3 clients,
transport adapters and daemons cannot communicate with this release. Upgrade
all Cue binaries together; integrations must adopt the v4 Scope/Execution/Run
contract rather than relying on the previous session/job protocol.

The default store is now cued-v4.db. On first default startup, the old
cued.db and its sidecars are archived as cued-v3-<timestamp>.db.archive.
Old sessions and execution history are not imported. Preserve the archive
if you need the old history; starting v4 is not a migration of that history.

Upgrade

Replacing installed binaries does not replace an already running daemon.
Stop existing work deliberately before upgrading. If a v3 daemon remains
running and the new client reports an incompatible handshake, use:

cued stop --force
cued start

For a custom endpoint, pass the same --socket PATH to both commands and the
original --db PATH to start. A service manager should launch
cued start --fg; stop the service first if it automatically restarts an old
process. Force stop sends SIGTERM and waits; it does not use SIGKILL or claim
success on a timeout.

Distribution

Release artifacts have passed build and installation smoke checks in GitHub Actions.

All nine Rust crates are published on crates.io at version 0.2.0. Install the
complete command set with:

cargo install cue-cli --version 0.2.0 --locked

PyPI and npm registry publication is pending authentication recovery. The three
platform wheels, source distribution, and npm Skill package are available as
GitHub Release assets below. cue-run==0.2.0 and @zendev-lab/cue@0.2.0 are not
yet available through their registries.
