 # CHANGELOG
 
+## 4.12.1 May 30, 2021
+
+Upgrade priority: Low. Internal adjustment only, no major external usage changes.
+
+Changelog:
+
+- Update `FundInfo` type with Polkadot (Thanks to https://github.com/arjanz)
+
+Changes:
+
+- Allow storage queries with default keys values
+- Align identity `Data` to limit to 32 bytes in the `Raw` enum (as per Substrate)
+- Align static (test & docs-only) metadata with latest Substrate master
+- Added 9030 upgrade blocks for Kusama & Westend
+- Cleanup of Eth pallet RPC definitions
+- Cleanup README for `@polkadot/rpc-core` (recommended for internal-usage only)
+- Cleanup internal tests (no dangling handles, cater for Jest 27)
+
+
+## 4.11.2 May 24, 2021
+
+Upgrade priority: Low. Recommended where users are having TS mismatches with type definitions created on older versions.
+
+Changes:
+
+- Add backwards-compatible TS-only `AugmentedQueryDoubleMap` type (unused now in type generation)
+
+
+## 4.11.1 May 23, 2021
+
+Upgrade priority: Low. Recommended for users using staking entries on Polkadot and users of Substrate master.
+
+Changes:
+
+- Fix metadata v13 storage decoding on `NMap`
+- Add augmentation & keys/entries for NMap types
+- Return additional error information from internal u8a decoding failures
+- Adjust Westend types for 16 nominators-only
+- Add support for `DisallowSigned` (as per shell runtime) extension
+- Display small hex-slice with u8a decoding failures
+- Add `state_getChildReadProof` RPC
+- Cleanup Rococo known types (only as used)
+- Under Node.js allow for WS receiving up to 16MB messages
+- Update entries/keys for max of 256 items per call
+
+
+## 4.10.1 May 17, 2021
+
+Upgrade priority: Medium. Recommended for uses of Polkadot/Kusama 9010 runtimes.
+
+- **Breaking change** Support for the contracts V2 compatibility has been dropped in `@polkadot/api-contract`
+
+Contributed:
+
+- Expose RPC definitions via `.meta` (Thanks to https://github.com/jiqiang90)
+- Adjust staking derives for chain-specific optional fields (https://github.com/WoeOm)
+- Update base Centrifuge types (Thanks to https://github.com/branan)
+
+Changes:
+
+- Allow for `Bounded*` type usage (as per latest Substrate)
+- Adjust internal TS definitions for providers
+- Fix `ContractRx` query result definitions (no extra Observable)
+- Handle contract call RPC result directly as `Raw` (returned as hex)
+- Use `BN_*` constants as non-specified defaults in contract interfaces
+- Remove all type overrides for node/node-template (API tracks latest)
+- Contracts ABI now supports metadata version where indexes are 0-based
+- Remove support for the old-style V2 contracts from `@polkadot/api-contract`
+- Adjust historic decoration, return as-at registry via `getHeader`, `getMetadata` & `getRuntimeVersion`
+- Adjust `VecFixed` to allow for the handling of hex inputs
+- Adjust `Compact<*>` to allow for wrapped `toBigInt()` conversions
+- Fix `isPedantic` decoding to correctly handle `Text`
+- Cater for new `phragmenElection` module naming
+- Add Kusama & Westend 9010 upgrade blocks
+- Adjust `CompactSolution` for 24 nominators
+- Bump static metadata to latest Substrate
+
+
 ## 4.9.1 May 6, 2021
 
 Upgrade priority: Medium. Required for the next v0.9.0 Polkadot/Kusama chain upgrades where parachains are used.

-This library provides a clean wrapper around all the methods exposed by a Polkadot network client.
-
-## Usage
-
-Installation -
-
-```
-yarn add @polkadot/rpc-core
-```
-
-Initialization -
-
-```js
-import Rpc from '@polkadot/rpc-core';
-import { WsProvider } from '@polkadot/rpc-provider/ws';
-
-const provider = new WsProvider('http://127.0.0.1:9944');
-const rpc = new Rpc(provider);
-```
-
-Retrieving the block header object for a given block header hash (a 0x-prefixed hex string with length of 64) -
-
-```js
-rpc.chain
-  .getHeader('0x1234567890')
-  .subscribe(
-    (header) => console.log(header),
-    (error) => console.error('error:', error)
-  );
-```
-
-Retrieving the best block number, parent hash, state root hash, extrinsics root hash, and digest (once-off) -
-
-```js
-rpc.chain
-  .getHead()
-  .pipe(
-    switchMap((headerHash) => {
-      return rpc.chain.getHeader(headerHash);
-    })
-  )
-  .subscribe(
-    (header) => {
-      console.log(`best #${header.number.toString()}`);
-      console.log(`parentHash: ${header.parentHash.toString()}`);
-      console.log(`stateRoot: ${header.stateRoot.toString()}`);
-      console.log(`extrinsicsRoot: ${header.extrinsicsRoot.toString()}`);
-      console.log(`digest: ${header.digest.toString()}`);
-    },
-    (error) => {
-      console.error('error:', error);
-    }
-  );
-```
-
-Retrieving best header via subscription -
-
-```js
-api.chain
-rpc
-  .subscribeNewHeads()
-  .subscribe(
-    (header) => {
-      console.log(`best #${header.number}`);
-    },
-    (error) => {
-      console.error('error subscribing:', error);
-    }
-  );
-```
+This library provides a clean wrapper around all the methods exposed by a Polkadot network client. It is only used internally to the API.
