Upgrading to synth-ai 0.11.2

What changed in the Managed Research SDK between 0.11.1 and 0.11.2, and what to use instead.

0.11.2 aligns the Managed Research SDK with the current backend, which made objectives, experiments, and milestones runtime-managed rather than directly created and stepped through the SDK. If you were on 0.11.1 and called those APIs, they returned 404 against the current backend; 0.11.2 removes them so the SDK matches what the service actually supports.

Only code that called the objective/experiment/milestone lifecycle, the typed open-ended-question / directed-effort-outcome helpers, connect-git, or project-scope economics / resource-limits is affected. The core flow — create a project, start a run, read results — is unchanged.

Install

pip install "synth-ai[research]==0.11.2"

What moved, and what to use instead

If you used (0.11.1)	In 0.11.2	Use instead
create_objective / pause / resume / withdraw / request_review / *_claim / lifecycle	removed	Objectives are advanced by the runtime; you no longer step them by hand.
list_objectives(project_id)	kept	unchanged
get_run_work_graph(...)	kept	the run’s objective/work graph
typed *_open_ended_question / *_directed_effort_outcome	removed	use the run brief; objectives are derived/managed at runtime
experiments CRUD + results	removed	experiment tracking is internal; read run outputs/artifacts
milestones CRUD + transition	removed	milestones are runtime-managed
get_project_resource_limits / progress_toward / extend (project scope)	removed	run-scope resource-limit APIs (*_run_resource_limits, extend_run_resource_limit)
get_project_economics	removed	project usage rollups (/usage)
connect-git (github / integrations)	removed	upload code bundles

How removed calls behave

Removed methods are gone (not silently no-op). MCP tools for the removed surface are filtered out of the advertised registry; any retained compatibility shim fails loudly with unsupported_backend_contract rather than returning a misleading result. If a call you relied on isn’t in the table above, check the package CHANGELOG.

Verifying your upgrade

pip install "synth-ai[research]==0.11.2"
# then re-run your quickstart — the create-project -> run -> read-results path is unchanged
