The lock has resolved 0.8.4 since 2025-12-09 while 0.9.0 and 0.10.0 have shipped, so nothing in this repository has ever been tested against either. Nothing pinned it there: every floor is a `>=`, every member is `requires-python >=3.10`, and the lock carries no constraints -- renovate's lock-file maintenance simply never picked the release up. `uv lock --upgrade-package openfeature-sdk` moves 0.8.4 -> 0.10.0 and touches nothing else. Two behaviour changes reach the tests. Neither touches the flagd source, which needs no change and stays clean under `poe mypy` on 26 files. First, 0.10.0 made `set_provider` non-blocking, so a test that sets a provider and evaluates on the next line now races initialisation and reads PROVIDER_NOT_READY -- 20 failures across test_errors.py and test_metadata.py. `set_provider_and_wait` restores the old blocking behaviour with one difference that matters here: it re-raises whatever `initialize` raised, where `set_provider` only dispatched PROVIDER_ERROR. Several of these scenarios feed the provider a deliberately broken flag file, so that raise is the scenario rather than a failure, hence the `contextlib.suppress`; it is not papering over an unexpected error. Second, 0.10.0 isolated event-handler dispatch onto a ThreadPoolExecutor where 0.8.4 called handlers inline -- open-feature/python-sdk#599. test_grpc_sync_fail_deadline read a flag set by a PROVIDER_ERROR handler on the line after the call returned, which is now a race: `_run_initialize` submits the event and then re-raises, and submit is not run. Rather than wait on the handler, the assertion goes: it existed because the old `set_provider` blocked and swallowed the error, leaving the event as the only way to observe a failed init, and `pytest.raises(ProviderNotReadyError)` now carries that claim directly. What the handler would assert today is that the SDK's registry dispatches PROVIDER_ERROR when `initialize` raises -- SDK plumbing, uniform across providers, and not this suite's to cover. The deadline measurement it shared the test with is untouched, though it now has to wait rather than time a call that would return immediately. The other two handler-driven tests here -- test_invalid_flag_set_metadata and the e2e event steps -- already poll with a timeout and need nothing. The tests are the only thing that needs 0.10.0, so the floor goes in flagd's dev group and the runtime floor stays at 0.8.2. Measured, not assumed: flagd is 208 passed at 0.8.4 and 208 passed at 0.10.0 after this change, having been 188 passed / 20 failed in between. CI covers tests/e2e, which needs docker, and reported 783 passed on this branch with the handler race as its only failure. The other nine packages pass tests and mypy unchanged, except unleash, which the next commit fixes. Signed-off-by: Simon Schrottner <simon.schrottner@flagsmith.com>

openfeature-sdk 0.9.0 added tracking, and `OpenFeatureClient.track` calls
`provider.track(tracking_event_name, merged_eval_context,
tracking_event_details)` -- three positional arguments. The provider's own
no-op declared `track(event_name, event_details=None)`, which takes two, so
the call raises
TypeError: UnleashProvider.track() takes from 2 to 3 positional arguments
but 4 were given
instead of doing nothing. Requirement 6.1.1 says the client's track MUST be a
no-op when the provider does not implement tracking, so the method that
exists to satisfy it was the thing breaking it.
This is reachable from a released install, not just from this branch: the
package declares `openfeature-sdk>=0.8.2`, so a fresh resolve takes 0.10.0
and any `client.track(...)` call raises. It went unnoticed because the
workspace lock held 0.8.4, where the SDK has no tracking API at all and
therefore never calls this method.
`AbstractProvider.track` is already a no-op with the signature the client
calls, so deleting the override is the whole fix. Widening the signature
instead would mean importing `TrackingEventDetails` for the annotation, and
`openfeature.track` does not exist before 0.9.0 -- with the floor at 0.8.2
that turns a broken `client.track` into a ModuleNotFoundError on import,
which is worse. Raising the floor to 0.9.0 would also work, but the provider
needs nothing from that release beyond a type it only uses to say it does
nothing.
Verified against both ends of the declared range: on 0.10.0, registering the
provider and calling `client.track("my-event")` raised TypeError before and
returns None after; on 0.8.4, importing the provider raises
ModuleNotFoundError with the annotation and imports cleanly without it.
mypy caught the narrow signature as two `[override]` errors against both
`AbstractProvider` and `FeatureProvider`; it was the only type error the
0.10.0 move produced anywhere in the workspace. The existing
`hasattr(provider, "track")` assertion could not catch it -- it holds either
way -- so the test now calls track the way the SDK does, which is also what
guards against the override coming back.
Fixes #433

Do not require an SDK API outside the declared dependency floor.
The package declares openfeature-sdk>=0.8.2, but AbstractProvider in 0.8.2 has no track method. UnleashProvider does not define one, so hasattr(provider, "track") fails in a minimum-version environment before the direct call. The inherited three-argument no-op exists in 0.10.0. Either raise the dependency floor to >=0.10.0, or define a provider-level no-op that supports both versions.

Why
uv.lockhas resolvedopenfeature-sdk0.8.4 since 2025-12-09; 0.9.0 and 0.10.0 have shipped since, so nothing here has ever been tested against either. Nothing pinned it — every floor is a>=, every member isrequires-python >=3.10, and renovate's lock-file maintenance never picked the release up.uv lock --upgrade-package openfeature-sdkmoves 0.8.4 → 0.10.0 and touches nothing else.What it took
Two behaviour changes in 0.10.0 reach the tests. Neither touches provider source.
set_provideris non-blocking. Setting a provider and evaluating on the next line now readsPROVIDER_NOT_READY— 20 failures in flagd'stest_errors.pyandtest_metadata.py.set_provider_and_waitrestores the old behaviour, but it also re-raises whateverinitializeraised; several of these scenarios feed the provider a deliberately broken flag file, so that raise is the scenario rather than a failure, hence thecontextlib.suppress.test_grpc_sync_fail_deadlineread a flag set by a PROVIDER_ERROR handler on the line after the call returned. The handler is dropped rather than awaited:pytest.raises(ProviderNotReadyError)now carries that claim directly, and what the handler would assert today is SDK plumbing. The deadline measurement is untouched.Only the tests need 0.10.0, so that floor goes in flagd's dev group; runtime floors are unchanged.
Separately, unleash's
track()override declared a narrower signature than the oneOpenFeatureClient.trackcalls, soclient.track(...)raisedTypeErrorinstead of no-opping — reachable from a released install, since the package allows 0.10.0.AbstractProvider.trackis already a no-op with the right signature, so the override is deleted rather than widened; widening would mean importingTrackingEventDetails, which does not exist before 0.9.0. Fixes #433.Verification
tests/e2eThe other nine packages pass tests and
poe mypyunchanged.tests/e2eneeds docker, so CI covers it — an earlier run on this branch reported 783 passed, its one failure being the handler race above. unleash checked at both ends of its declared range: imports cleanly on 0.8.4,client.trackno-ops on 0.10.0.Notes
Titled
chore(deps):, so release-please will cut no unleash release from it — retitle on merge, or I can follow up.Out of scope: every provider README shows
api.set_provider(...)followed by an immediate evaluation, which is now racy for any provider with a real initialisation. Worth its own docs pass.
