# 0.82.0-beta.x
|
|
|
|
- **Breaking change** The `ContractsAbi` type has been moved from `@polkadot/types` to `import { Abi } from '@polkadot/api-contract`. This paves the way for an enhanced contracts interface, instead of dealing with low-level API calls.
|
|
- **Breaking change** `usize` is now a blacklisted type that will throw on construction. Since it is platform-specific, it creates incompatibilities between native (generally u64) and WASM (always u32) code. Use one of the `u32` or `u64` types explicitly.
|
|
- **Breaking change** `api.derive.contract` is now `api.derive.contracts` to align with the substrate 2.x rename. (Feture detection is used so it supports both 1.x and 2.x chains)
|
|
- **Breaking change** The api now uses the module name instead of the prefix to generate the storage methods. The methods of the grandpa module changed from `api.query.grandpaFinality` to `api.query.grandpa`.
|
|
- Update with latest substrate 2.x types
|
|
- **Breaking Change** StorageFunction has been renamed to StorageEntry.
|
|
- **Breaking Change** `@polkadot/extrinsics` and `@polkadot/storage` have been moved to `@polkadot/api-metadata` and are now accessible as `@polkadot/api-metadata/extrinsics` and `@polkadot/api-metadata/storage`, respectively.
|
|
- **Breaking Change** Vote interface extends U8a instead of I8. Vote properties can be accessed via the `isAye`, `isNay`, and `conviction` getters. Votes can still be constructed as before with a raw JS boolean, a SCALE encoded Boolean, an i8 number, or a JS object with properties `aye` and `conviction` defined.
|
|
- Support latest substrate 2.x v6 metadata with module constants using `api.consts`.
|
|
|
|
# 0.81.1
|
|
|
|
- The dependency on `@polkadot/keyring` has been removed - if you relied on the API to provide this, you would now need to manually add it
|
|
- Update `HeaderExtended` to retrieve author information from substrate 2.x (new `PreRuntime` digests)
|
|
- `createType` allows for the creation of `[u8; <length>]` types (opening the door for contract support)
|
|
- `api.derive.staking.info` now returns the `rewardDestination`
|
|
- Fix for disconnection when default providers (non-specified) are used
|
|
- Don't console.log type decoding errors and then throw, only re-throw with additional info
|
|
- Support latest substrate 2.x v5 metadata
|
|
- Add support for new inherent digests from substrate.
|
|
- **Breaking change** Because of the new `Seal`, the old/new Seals are not compatible. If you were using the old `Seal` from the `Digest`s, you would now use `isSealV0` for the pre-substrate 1.0 version and the new `isSeal` for the current version
|
|
- Add `ApprovalFlag`, `SetIndex`, `VoterInfo` types for council as per substrate
|
|
- Update `ContractInfo` to match substrate master
|
|
- Cater for `Vec`, `Option`, `Result`, tuples and fixed vectors for contracts ABIs
|
|
- Additional examples for subscriptions using multi
|
|
- Add `off` method to `Api` (Base, for both `ApiPromise` & `ApiRx`) to remove an event listener
|
|
|
|

|
- `types/codec/Set` now extends the base JS `Set` (**breaking change**: `set.values` -> `set.strings`)

|
|
- Start journey to 1.0
|
|
|
|
# 0.53.1
|
|
|
|
- Change spelling to US English as per substrate master (1.0-rc1). Breaking changes as a result:
|
|
- For extrinsic status results, if you have checked the type returns, i.e. `result.type === 'Finalised'` now check on the status for `result.status.isFinalized` or `result.status.isBroadcast`, ... (the `type` property is now accessible only on `result.status.type`)
|
|
- If using `subscribeFinalisedHeads` update this to `subscribeFinalizedHeads` (likewise `getFinalisedHead` should be updated to `getFinalizedHead` and `derive.bestNumberFinalized`)
|
|
- The underlying ss58 addess checksums have changed in the keyring along with the latest specs
|
|
- All examples have been updated with sr25519 addresses (with the new checksums)
|
|
|
|
# 0.52.1

- Support queries to linked mapped storage (found in new staking interfaces)
|
|
- Add `derive.staking.controllers` to retrieve all active staking controllers
|
|

- Allow parsing of V3 metadata with DoubleMap support
|
|
- Check for single instances for api and types as they are loaded (assertSingletonPackage)
|
|
|
|
# 0.51.1
|
|
|
|
- Support metadata V2 as per latest substrate master
|
|
- Update metadata with new types as per lastest substrate master
|
|
|
|
# 0.50.1
|
|
|
|
- Lastest util-crypto (usage of WASM with JS fallbacks if not available)
|
|
- Update upstream @polkadot dependencies (for new crypto)
|
|
|
|
# 0.49.1
|
|
|
|
- Fix large message signing on non-known nodes (default is now hashing, there has been enough time between upgrades)
|
|
|
|
# 0.48.1
|
|
|
|
- Pull in new sr25519 capable keyring for dev nodes
|
|
- When using dev mode, it assumes that the node is the latest with derived sr25519 keys
|
|
|
|
# 0.47.1
|
|
|
|
- Swap to publishing -beta.x on merge (non-breaking testing)
|
|
|
|
# 0.46.1
|
|
|
|
- Extended type registration to now handle internal types as well. Additionally the built-in Extrinsic type can now we overridden with a custom version.
|
|
- Where `Extrinsic` and `Method` is used as types, considder importing `{ IMethod, IExtrinsic }` from `@polkadot/types/types`, especially in the cases where this is uased from a `SubmittableExtrinsic`
|
|
- The `typeRegistry` constant is now `getTypeRegistry()` as a function
|
|
|
|
# 0.45.1
|
|
|
|
- Storage with option values now correctly return `Option<Type>` and is indicated as such in the documentation
|
|
|
|
```js
|
|
// old
|
|
const ll = await api.query.session.lastLengthChange();
|
|
|
|
console.log('ll', ll /* BlockNumber */); // would be 0 if not set yet
|
|
|
|
// new
|
|
const llo = await api.query.session.lastLengthChange();
|
|
|
|
console.log('llo', llo.unwrapOr('not set') /* Option<BlockNumber> */)
|
|
```
|
|
|
|
# 0.44.1
|
|
|
|
- Split primitives and types into seperate folders. This should not affect external use since the exports remain the same, however does have an impact where classes are referenced directly. e.g.
|
|
|
|
```js
|
|
// old (affected)
|
|
import Method from '@polkadot/types/Method';
|
|
import Signature from '@polkadot/types/Signature';
|
|
|
|
// new locations
|
|
import Method from '@polkadot/types/primitive/Method';
|
|
import Signature from '@polkadot/types/type/Signature';
|
|
|
|
// unaffected
|
|
import { Method, Signature } from '@polkadot/types';
|
|
```
|
|
|
|
# 0.43.1
|
|
|
|
- Intrduces support for the new keyring with sr25519 support in addition to ed25519. While this does not change the exposed API, it is considerred breaking since @polkadot/keyring has interface changes. (Unless needed, don't rush the upgrade)
|
|
|
|
# 0.42.1
|
|
|
|
- Support for substrate hash signing with implVersion >= 18
|
|
- Changed signatures for Extrinsic signing, this should not have (much) of an impact since it is generally not used directly. SubmittableExtrinsic (as exposed by the API), supports the old-style use.
|
|
|
|
# 0.41.1
|
|
|
|
- Support the V1 metadata specification from Substrate in addition to the currently testnet-active V0 version
|
|
|
|
# 0.40.1
|
|
|
|
- The API interfaces now require a WS-compatible provider, e.g. subscription support is a must. Previously the HTTPProvider could be use (although it was very limited in the interactions).
|
|
|
|
# 0.39.1
|
|
|
|
- The Promise API now returns a `Promise<UnsubFunction>` instead of `UnsubFunction` when making subscriptions.
|
|
|
|
# 0.38.1
|
|
|
|
Substrate has been updated with a breaking new transaction format where the Index/Nonce is now encoded as a Compact. This change is being rolled out to both Alexander (Polkadot testnet) as well as Charred Cherry (Substrate testnet) - transactions between old and new are not compatible.
|
|
|
|
# 0.37.1
|
|
|
|
api-observable has been removed. This was only used in /apps and inconsistent with the api/rx and api/promise APIs. Future work will include derivates like was included in api-observable into the base.
|
|
|
|
Tuples now return single types when only one type is available, i.e. `(AccountId)` would now resolve as `AccountId`. The extra type wrapper adds no benefit to users here.
|
|
|
|
# 0.36.1
|
|
|
|
Api Promise has been updated in the way we deal with subscriptions. Previously a subscription returned `Promise<number>` where the caller was to keep track of the id and use it in subsequent unsubscribes. Now any subscriptions return an unsubscribe/destroy function `(): void`, that is use for removing the subscriptions, e.g.
|
|
|
|
```js
|
|
const unsubscribe = api.query.balance.freeBalance(Alice, (balance) => {...});
|
|
|
|
unsubscribe(); // here we destroy the subscription
|
|
```
|
|
|
|
# 0.35.1
|
|
|
|
Swapped to new metadata structures from Substrate. If the API is not working with your node, update Substrate to latest master branch. (Or 0.9.1 for Charred Cherry). Dropped support for old metadata as found as far back as BBQ Birch.
|
|
|
|
# 0.34.1
|
|
|
|
Changed the send signature (for future expansion of eg. events) to return `result: { status: ExtrinsicStatus }` instead of `status: ExtrinsicStatus`. For most cases where only status `type` checks are used, i.e. `status.type === 'Finalised'` this should not be a breaking change. Deep inspection of the status object however will need to adapt.
