This release includes the latest stable version of the @polkadot/api package, v1.8.1.

Changes:

Breaking Changes:

• /api/query/staking/stakers has been changed to /api/query/staking/erasStakers. The account_address parameter has been changed to account_id and the optional parameter era_index has been added.
• /api/query/staking/currentElected has been changed to /api/derive/staking/validators. The new endpoint now returns both validators, the list of validators which are active in the current session, as well as nextElected, the list of validators which will be active in the next session.
