v1.9.1

• Breaking change (TypeScript with derives only) The return type names for api.derive.* have been adjusted for consistency, all starting with Derive* (previously a mixture of Derived* and Derive*)
• Breaking change (derives only) Additional cleanups of democracy proposal & referenda derives, including support for new Polkadot/Substrate vote retrievals

v1.8.1

• Breaking change The format for any custom RPCs have been changed alongside API-internal changes to allow for better RPC management. If you are currently using custom RPCs (or planning to do so), look at the updated documentation
• Breaking change Alongside API RPC changes, the @polkadot/jsonrpc package has been removed. Since it was never documented and only used internally, this should not have adverse impacts. All RPC definitions itself has now been moved to the relevant modules inside @polkadot/types/interfaces
• Important Substrate has an updated democracy module. If using an older chain add the ReferendumInfo: 'ReferendumInfoTo239' type when using referendums
• The isRetracted Extrinsic status is now a warning, not a fatal error, correctly aligning with Polkadot/Substrate

• Extend account derives to include status flags, e.g. isCouncil, isSudo, ...
• Adjusted referendum derives to cater for bot new/old democracy. Derived referendumInfo now includes status field, not info
• Add initWasm flag to API options, that when set to false does not init the WASM portion (leaving it to the user elsewhere)

v1.7.1

• Important Current versions of Polkadot/Substrate have dropped support for linked maps on storage entries. If you are using these queries to retrieve all entries, for instance staking.{nominators,validators}() and using an upgraded chain, you need to swap to retrieving entries via .entries() or .keys() for the keys.

• Add support for the new Substrate state_getKeysPaged RPC, including use in storage keys
• Move derive.staking.controllers to derive.staking.stashes, reflecting actual content
• Cater for adjusted storage (non-linked mapped) for derive.staking.stashes queries (with old-compat)
• Expanded derive.staking.* derives, including addition of derive.staking.own*
• Re-add fixed (with tests) checks for query args, previously disabled in 1.6.2

v1.6.2

• Revert checks for query args, not working on .at() queries (proper fix in next version)

v1.6.1

• Breaking change api.rpc.state.queryStorage(...) now fully decodes the Vec<StorageChangeSet> and returns a decoded [Hash, Codec[]][] when using this RPC.
• StorageKey now has an .args property, decoded from meta where twox64_concat or blake128_concat are used on maps
• Fix api.query.*.*.entries type conversions to return exact types (not Option in some cases)
• Add api.query.*.*.keys to retrieve only the storage keys, similar to .entries
• Full linked map retrievals will now use direct getStorage queries for faster operation
• Underlying rpc-core interfaces now unwraps Error("...") when found in responses
• Added derive.eras* interfaces for queries to new Substrate staking interfaces
• Update derive.account to cater for new indices module storage (detected with fallbacks)
• Adjust derive queries for session without module prefix (DoubleMap -> Map), detected on use
• Add runtime validation for map arguments to api.query.*
• TypeScript interfaces for linked maps now correctly generates as [Type, Linkage<Next>]
