 # CHANGELOG

+## 3.7.3 Feb 2, 2021
+
+Changes:
+
+- Added Polkadot upgrade block for runtime 27 (known checkpoint optimization)
+
+
+## 3.7.2 Feb 2, 2021
+
+Changes:
+
+- Adjusted the `Keys` type for the 28 runtime on Kusama, Polkadot & Westend
+
+
+## 3.7.1 Feb 1, 2021
+
+Upgrade priority: Low. However recommended for current Substrate master, Polkadot and Rococo users and those wishing to support the upcoming Polkadot 28 runtime with the new `MultiAddress`.
+
+- **Breaking change** As indicated in the 3.5.1 release notes, the `Address`/`LookupSource` defaults have now been adjusted for `MultiAddress`. If your chain does not use these types, explicitly add the correct `Address`/`LookupSource` types. This new extensible format is mean to cater for all address types into the future, removing a lot of discrepancies between chains.
+
+Contributed:
+
+- Extraction of the block author on Moonbeam (Thanks to https://github.com/joelamouche)
+- Cleanup logs with HTTP providers, no subs (Thanks to https://github.com/Tbaut)
+
+Changes:
+
+- Allow `.slice` operator on the `Vec` type
+- Apply `MultiAddress` as a default
+- Adds support for the upcoming Polkadot 28 and Kusama 2028 runtimes
+- Add checkpoint for Kusama 2027 upgrade
+- Update all parachain types (as per latest Rococo)
+- Correctly use relay blockNumber in parachain validation data
+- remove information log for capabilities detection (creates confusion)
+- Remove explicit references to `global`, use the `x-global` detection
+- Remove explicit `module` in `package.json` (exports map available)
+
+
+## 3.6.1 Jan 24, 2020
+
+Upgrade priority: Medium if not already on at least 3.3.1. The next upgrade of Kusama/Polkadot requires it.
+
+- **Breaking change** To support chains with multiple tokens, such as bridges, the `ChainProperties` type now returns an array of tokens and decimals (instead of singular values) in the `token{Decimals, Symbol}` getters. Additionally, this means that the `registry` interfaces has been changes, to `registry.chainDecimals: number[]` and `registry.chainTokens: string[]`. Where used the `[0]` index will return the first value if only interested in a single, for a straight conversion.
+
+Changes:
+
+- Allow for the detection of on-chain capabilities as available (e.g. `AccountData`, `ValidatorPrefs`)
+- Cater for multiple tokens and decimals in the chain the chain `system.properties` (as per the chain specification)
+- Add a `instances: { [key]: [module1, module2] }` definition in teh bundle types, allowing for multiple instances (e.g. Balances)
+- Adjust the `api-derive` for balances to retrieve values via `instances` as well as across multiple modules
+- Ensure all types are registered for all metadata typegen steps
+- Add `rpc.payment.queryFeeDetails` RPC endpoint
+- Update types & metadata to latest Substrate
+- Move the `@polkadot/x-rxjs` package into the common repo
+- Allow doc generation for errors/events (markdown outputs)
+
+
+## 3.5.1 Jan 18, 2020
+
+Upgrade priority: Low. Recommended for parachain developers.
+
+- **Important** The default for Substrate on the Address types are `MultiAddress`. It is recommended that chains add explicit definitions for `Address` and `LookupSource` in their types, instead of relying on the API-defaults. A future update will swap the API defaults to align with Substrate.
+- **Important** Like the above changes in Substrate, the `AccountInfo` structure has also changed. It is recommended that chain developers explicitly add `AccountInfo: 'AccountInfoWithRefCount'` for the version with `refCount` on and `AccountInfoWithProviders` for the latest Substrate version. As per the above, the API defaults will be changed to align with Substrate.
+
+Contributed:
+
+- Apply correct TypeScript type for `toBigInt()` (Thanks to https://github.com/ianhe8x)
+- Expand type definitions for storage key tuples (Thanks to https://github.com/monitz87)
+- Adjust bounty derive to cater for non-council chains (Thanks to https://github.com/ekowalsk)
+
+Changes:
+
+- Remove recursion in vector/struct U8a stream decoding
+- Availability of staking made optional in session length calcs (era does require it)
+- Updates to parachain types, ensuring it has coverage for all the latest
+- Update all Rococo types to the latest (session keys, session reports, parachain indexes)
+- Update known upgrade checkpoints fo WestEnd
+- Add types of the lottery module in Substrate
+- Add and extend types for the crowdloan module in Polkadot
+- Adjust node-template to default to `MultiAddress` on specVersion >= 100
+
+
+## 3.4.1 Jan 11, 2020
+
+Upgrade priority: Low. Fixes for parachain types, `.entries()` (with no values) and `event.is(...)` checks, users of these interfaces will have benefit.
+
+- **Breaking change** The `derive.chain.{getBlock, subscribeNewBlocks}` now return `SignedBlockExtended`, all with the actual extrinsics and events mapped. Users of the latter interface should take note.
+
+Contributed:
+
+- Fix `SessionKeys{6-9}` definitions (Thanks to https://github.com/icodezjb)
+- Support `Vec<(a, b)>` in enums (Thanks to https://github.com/monitz87)
+- Add motions to bounty derive (Thanks to https://github.com/ekowalsk)
+
+Changes:
+
+- `derive.chain.getBlock()` now maps events to extrinsics via `.extrinsics` getter
+- Ensure dispatchInfo is extracted on failed extrinsics (`getBlock` derive)
+- Allow specification of additional signed extrinsic via API options
+- Add missing parachain types, `ParaGenesisArgs`
+- Correct `EthTransaction` type (as per the correct cargo crate)
+- Update with latest contract types for Substrate master
+- Update alias mapping for asset palette (including Substrate starting defaults)
+- Allow `.entries()` call where 0 keys are present
+- Fix `.is` on events not checking the correct index
+- Construction of `i*` types ow correctly checks for max positive/negative
+
+
+## 3.3.1 Jan 4, 2021
+
+Upgrade priority: Low. Recommended for users of frontier evm module with additional types.
+
+Contributed:
+
+- Expand bounty derives (Thanks to https://github.com/ekowalsk)
+- Adjust known-types (Thanks to https://github.com/mikiquantum)
+
+Changes:
+
+- Parallelize the API-init RPC calls for faster overall startup
+- Add `ExitReason` types for the frontier evm module
+- Adjust checks for indexed/non-indexed module checks (metadata decoration)
+- Apply module aliases on constants (aligning with events, extrinsics)
+- Allow for use of `system.ss58Prefix` as exposed (current Substrate master)
+- Correct use of api-contract `blockWeights.maxBlock` in estimation
+- Build metadata docs & interfaces with section aliases
+- Update to latest Substrate master metadata in tests
+
+
+## 3.2.1 Dec 27, 2020
+
+Upgrade priority: Low. Recommended for users of parachains.
+
+Contributed:
+
+- Adjust metadata `.asV12` type signature (Thanks to https://github.com/yjhmelody)
+
+Changes:
+
+- Add `api.{errors, events, query, tx}.<section>.<name>.is(...)`
+- Remove support for staking pre Substrate 2.0
+- Add all frontier types & RPCs
+- Support `AccountInfo` with new provider/consumer refCount structure
+- Additional Cumulus parachain types
+- Consistently format number JSON based on bitLength
+- Cleanup metadata -> api dependencies
+- Update `@polkadot/util` to 5.2.1
+
+
 ## 3.1.1 Dec 20, 2020
