 # CHANGELOG
 
+## 1.24.1 Jul 13, 2020
+
+- Added `isAscii` & `isUtf8` getters to `Bytes` & `Raw` types
+- Added `toUtf8()` helper to `Bytes` & `Raw` types
+- `@polkadot/util` 2.18
+
+## 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)
+- `@polkadot/util` 2.17
+
+## 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
