• Important Chains without balances.account or system.account should supply "BalanceLock": "BalanceLockTo212" to their types to use the previous-generation BalanceLock (when querying locks)
• Add support for balances.account in all applicable derives (incl. vesting module)
• Inject and use SignedExtensions by name from V11 metadata (V4 extrinsics only)
• Add typings for api.tx.*.* - the polkadot-types-from-chain now also generates these
• Remove additional V1-only derives (staking.recentlyOffline, balances.nominatorsFor)
• Add .isMax() on int values, an opposite of isZero() (e.g. u128, as well as derived, e.g. Balances)
• Add .keyPrefix() to all api.query.* complementing the .key() call, both returning a hex string
• Council derives now takes bootstrapping (member, no elections) into account
• Account derives now allow for an optional indices module (not required)
• Adjust balances fees derivation with optional transfer and creation fees (removed in Substrate)
• Adjust enum .toJSON() to return type name as specified
