+# @polygonlabs/meta
+
+## 1.0.0
+
+### Major Changes
+
+- 0c1d7e5: Initial release of `@polygonlabs/meta`, replacing the legacy `@maticnetwork/meta@2.x` package.
+
+  ## What's new
+  - **Per-contract typed deep imports.** `import { abi } from '@polygonlabs/meta/abi/<chain>/<network>/<type>/<Contract>'` pulls exactly one ABI; the rest of the package is tree-shaken at bundle time.
+  - **`as const` literal ABI types.** Each ABI is exported as a literal tuple so `viem`, `wagmi`, and `abitype` can extract function names, argument types, and return types at the call site. Without `as const` the type widens to `{ name: string }[]` and consumer-side type inference disappears entirely — the typed-ABI value proposition exists only because of `as const`.
+  - **Typed network metadata** under `/info/<chain>/<network>` and `/info/networks`, also `as const`.
+  - **Raw JSON access preserved.** The `./network/*` subpath export keeps the same path scheme as `@maticnetwork/meta@2.x`, so consumers who only want JSON migrate by changing the package name.
+  - **Provenance-stamped publishes** via npm OIDC trusted publishing, driven by changesets-on-merge.
+
+  ## Breaking changes vs `@maticnetwork/meta@2.x`
+  - **Package renamed**: `@maticnetwork/meta` → `@polygonlabs/meta`.
+  - **ESM-only.** `require()` is no longer supported. Consumers must be ESM and on Node ≥ 24.
+  - **The `Network` class is gone.** Replace `new Network(chain, version).abi(name)` with the typed deep imports under `./abi/<chain>/<network>/<type>/<Contract>` — same data, fully typed, sync, tree-shakable.
+  - **Mumbai testnet** is gone (already removed upstream); use Amoy.
+
+  The HTTP endpoint at `static.polygon.technology` is unchanged. See `MIGRATION.md` for full before/after import examples.
