 # CHANGELOG
 
+## 1.23.1 Jul 6, 2020
+
+- Small README typo fix (Thanks to https://github.com/woss)
+- Add latest Substrate master types
+- Adjust `<Codec>.toRawType()` to use registry name as available
+- Update `ProxyType` for Kusama, Polkadot & Westend with `IdentityJudgement`
+- Validate number format (signed/unsigned) for number types
+- Remove core codec dependencies on Base class (with proper TS encapsulation)
+
+## 1.22.1 Jun 30, 2020
+
+- **Important** Substrate changed the treasury tip structure, on older chains supply `OpenTip: 'OpenTipTo225'`
+- Allow for `[u8; 33]` in U8aFixed (Thanks to https://github.com/akru)
+- Improve derive accountId -> accountIndex lookups (optimize entries queries)
+- Vesting balance calculations via `derive.balances.all` has been updated for locks
+- Add derive for multi staking rewards with specified eras
+- `@polkadot/util` 2.16
+
+## 1.21.1 Jun 23, 2020
+
+- Fix subscriptions never unsubscribing after the id swap in 1.18.1 (Thanks to https://github.com/dillu24 for testing iterations)
+- Add support for `CheckMortality` signed extension (old `CheckEra` is now an alias)
+- Promise API will default to using `getStorage` on non-subscription calls, reducing RPC overhead
+- Optimize derive BN allocations, using in-place operators as applicable
+- Add new substrate types for Babe EquivocationProof
+- Adjust `Releases` enum to use a shared instance
+
+## 1.20.1 Jun 22, 2020
+
+- **Important** RPC for `account_nextIndex` has been moved to `system_accountNextIndex` (Aligning with Substrate as a primary alias)
+- Cleanup map entries support with only Substrate 2.0-era RPCs (when introduced)
+- Add `system_dryRun` RPC
+- Optimize `derive.staking.queryMulti` retrievals with additional per-type batching
+- Add `derive.staking.waitingInfo` (same as `electedInfo` for waiting validators)
+- Adjust types & metadata for latest Substrate
+- `@polkadot/util` 2.15
+
+## 1.19.1 Jun 16, 2020
+
+- Improve typing on `.entries()` queries (Thanks to https://github.com/monitz87)
+- Align metadata and types with latest Substrate
+- Update Polkadot types for current evolution of parachains
+- Allow for type aliasing on events (aligning with calls & queries)
+- `@polkadot/util` 2.14
+
+## 1.18.1 Jun 8, 2020
+
+- Expand docs on node-template types (Thanks to https://github.com/g2udevelopment)
+- Update contract fees to current impl. (Thanks to https://github.com/djuanit0x)
+- Allow `Option` types in enum/Result type generation (Thanks to http://github.com/xlc)
+- Add `.entriesPaged` and `.keysPaged` methods for state maps (https://github.com/monitz87)
+- Add types for new Substrate proxy module
+- Adjust types for new Substrate (renamed) npos-elections module
+- `Call` now exposes `method` & `section` fields (aligned with `toHuman()` representation)
+- Cater for new Substrate string subscription ids (with backwards compatibility)
+- `@polkadot/util` 2.13
+
 ## 1.17.2 Jun 2, 2020

 To fix this, you should look at the specific `api.tx.*` params and adjust the type definitions for those param types to match what is found on the node side. In some rare cases the cause could be extrinsic formatting related, to track these make an `api.tx.system.remark(data: Bytes)` call, if it fails, the API and node cannot agree on [an extrinsic format and adjustments are required](types.extend.md#impact-on-extrinsics).
 
+If you are using a node-template based version of substrate and you changed the specName you need to add these typings(In addition to other custom types) `{"Address": "AccountId","LookupSource": "AccountId"}`. This is also the case when you use [polkadot-js/apps](https://github.com/polkadot-js/apps) to connect to your node. When the specName stays node-template the API is smart enough to add the custom typings.

 ## I would like to sign transactions offline
 
 The API itself is independent on where the signature comes from and how it is injected. Additionally it implements a signer interface, that can be used for external signing - an example of this is the [polkadot-js/apps](https://github.com/polkadot-js/apps) support for signing via extensions and even the [polkadot-js/extension](https://github.com/polkadot-js/extension) support for tools such as the [Parity Signer](https://github.com/paritytech/parity-signer).
