- New lib/crewai-core/ package: version, paths, constants, lock_store, user_data,
printer, telemetry. Pure leaf — depends only on appdirs/portalocker/rich/otel.
- crewai now depends on crewai-core; old crewai.utilities.{version,paths,printer,
lock_store} and the user-data block of events/listeners/tracing/utils.py become
one-shot DeprecationWarning shims that re-export from crewai_core.
- crewai-cli drops its hard dep on crewai and depends only on crewai-core. CLI
imports for telemetry/version/printer/constants now point at crewai_core.
- tools/main.py lazy-imports project_utils + get_user_id; the publish/login
subcommands print a friendly "requires crewai" error if it's missing.
- crewai-cli is now genuinely standalone: 'crewai --help', 'version', 'login',
'config', 'traces', 'create', 'template' all work without crewai installed.
- 351 CLI tests + 9 crewai-core smoke tests + crewai's full mypy (471 files) clean.
Add fork classmethod, _restore_runtime, and _restore_event_scope
to BaseAgent. Fix from_checkpoint to set runtime state on the
event bus and restore event scopes. Store kickoff event ID across
checkpoints to skip re-emission on resume. Handle agent entity
type in checkpoint CLI and TUI.
- Rewrite TUI with Tree widget showing branch/fork lineage
- Add Resume and Fork buttons in detail panel with Collapsible entities
- Show branch and parent_id in detail panel and CLI info output
- Auto-detect .checkpoints.db when default dir missing
- Append .db to location for SqliteProvider when no extension set
- Fix RuntimeState.from_checkpoint not setting provider/location
- Fork now writes initial checkpoint on new branch
- Add from_checkpoint, fork, and CLI docs to checkpointing.mdx
Accept CheckpointConfig on Crew and Flow kickoff/kickoff_async/akickoff.
When restore_from is set, the entity resumes from that checkpoint.
When only config fields are set, checkpointing is enabled for the run.
Adds restore_from field (Path | str | None) to CheckpointConfig.
Write the crewAI package version into every checkpoint blob. On restore,
run version-based migrations so older checkpoints can be transformed
forward to the current format. Adds crewai.utilities.version module.
