+| Azure Functions Durable Provider | Azure Functions v4 compatibility provider | `packages/azure-functions-durable/CHANGELOG.md` |
 
 The Azure package **peers on** the core package — it adds authentication and connection
 management but delegates all domain logic to core.

 This is an **npm workspaces** monorepo. The official build (`eng/ci/official-build.yml`) produces signed `.tgz` artifacts, and the **sanctioned way to publish them to npm is the ESRP release pipeline** (`eng/ci/release.yml`, see Step 3 below). A manual `npm publish` from the package directory is documented as an alternative for maintainers who need it.

-### One-Time Preflight: Seed the `azuremanaged` Release Tag
+### Automatic Legacy Baseline for Azure Managed
 
-The changelog step lists commits since the released package's **last package-scoped tag** (`git log <last-tag>..HEAD -- <pkg-dir>`); if no tag with that package's prefix exists, it falls back to the repo's initial commit and would dump the entire history into the changelog. `@microsoft/durabletask-js-azuremanaged` uses the `azuremanaged-v` prefix and has no such tag yet — the last lockstep release is the unprefixed `v0.3.0`. **Before the first independent `azuremanaged` release**, seed its tag so changelog generation starts at `v0.3.0` instead of the repo root:
-
-```bash
-git tag azuremanaged-v0.3.0 v0.3.0
-git push origin azuremanaged-v0.3.0

+The changelog step lists commits since the released package's **last package-scoped tag** (`git log <last-tag>..HEAD -- <pkg-dir>`). If Azure Managed has no `azuremanaged-v` tag yet, the workflow automatically checks for the legacy lockstep tag `v${CURRENT_VERSION}` and uses it as the baseline. This keeps the first independent Azure Managed changelog scoped to changes after its matching legacy release without requiring a manually seeded tag. If neither tag exists, the workflow falls back to the repository's initial commit.
