 # CHANGELOG
 
+## 4.14.1 Jun 14, 2021
+
+Upgrade priority: Low. Internal adjustment only, no major external usage changes.
+
+Contributed:
+
+- Adjust types for uniques (Thanks to https://github.com/hamidra)
+- Add `ValidationCodeHash` type (Thanks to https://github.com/andresilva)
+- Extend `OriginCaller` type creation (Thanks to https://github.com/xlc)
+
+Changes:
+
+- Do strict length checking on `[u8; <length>]` type inputs
+- Adjust keys/entries retrieval batch sizes
+- Add upgrade block for Kusama 9040
+- Use `BN` imports from `@polkadot/util`
+
+
+## 4.13.1 Jun 6, 2021
+
+Upgrade priority: Medium. Required for users connecting to Statemine and future Kusama upgrades.
+
+Changes:
+
+- Overrides for `westmint` spec (same as `statemint`)
+- Adjust `tx.session.setKeys` TS augmentation to allow `string` & `Uint8Array` keys
+- Add & adjust types for latest Cumulus code
+- Added 9031-9033 upgrade block for Westend
+- Update static metadata to latest Substrate
+- Optimize map retrieval with split page sizes for keys & values
+- Sanitizing `BN` imports to `type`-only as required
+
+
+## 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.
+
+- **Breaking change** The previously deprecated contracts interfaces, has been removed. Update to `<myContract>.query.*`, `<myContract>.tx.*` and `<myCode>.tx.*` interfaces as per the previous code usage hints.
+- **Important** By default the `isPedantic` mode is now switched on for storage queries. This means that the API will fail on any types where the input/output decoding doesn't match 100%
+
+Changes:
+
+- Re-add isPedantic check on storage decoding
+- `ConsensusEngineId` now implements `[u8;4]` (mapping closer to Rust source)
+- Additional Xcm types
+- Adjust parachain types
+- Remove error logging on createType (details passed in error)
+- Adjust `ContractInfo` type as per latest Substrate
+- Adjust `DigestItem` type as per latest Substrate
+- Adjust re-encoding of `BitVec` based on decoded length
+- Added `contracts_instantiate`, `state_traceBlock` & `system_reservedPeers` RPCs
+- Prepare for auto-capability detection with historic `.at` queries
+- Add known upgrade block for Westend 900 & 9000
+- Remove all deprecated interfaces inside `@polkadot/api-contracts`
+- Initial support for NMap storage keys
+- Support metadata v13 from Substrate (upcoming upgrade)
+- Optimize historic metadata retrieval from rpc core
+
+
 ## 4.8.1 May 2, 2021
 
 Upgrade priority: Low. Recommended when using or developing for parachains.
