+- **Important** Update RPC status codes (latest Substrate 2), with the `isInBlock` (`isFinalized` now indicates finality)
+- Storage `.entries(arg?: any)` now has the correct argument type for DoubleMap (Thanks to https://github.com/monitz87)
+- Swap Kusama and Polkadot aliasses for `Address` to `AccountId` (future update)
+- Add `LookupSource` and `LookupTarget` types instead of mapping these directly for aliassing
+- Add `BitVec` type primitive
+- Add support for `system.account` for balance & nonce queries in derives as well as Submittables (Substrate composites)
+- Add `rpc.author.hasKey` and `rpc.author.hasSessinKeys` RPCs
+- Add derives for the parachains interfaces
+- Applied the latest types for Polkadot parachains
+- `registry.findMetaError` now can take in a `DispatchErrorModule` object for error lookups (from `asModule` in `DispatchError`)
+- Metadata now correctly serializes to the original input data via `toHex()` & `toU8a()`
+- Metadata dcocumentation generation rework, including the output of errors from metadata
+- Update all examples and comments to use latest `system.account` queries (instead of `system.accountNonce` and `balances.freeBalance`/`balances.reservedBalance`)
+- Cleanup `codec/Date` tests to make it run properly on all timezones
+- Add explicit dependencies to all packages and move TypeScript `@types/*` to dev deps
+
+# 1.1.1 Feb 06, 2020

+- **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

 Polkadot/Substrate supports both immortal and mortal transactions. For immortal, this means that the transaction has an infinite lifetime, for mortals, the transactions expire after a defined period. By default the API sends mortal transactions when no explicit extrinsic era has been specified. This means that all transaction has a limited lifetime and will expire if not included in the period set.

 The length for this transaction validity is set to 50 blocks, which translates to 5 minutes assuming a default of 6 second blocktimes. (10 blocks per minute in this default configuration).

 The above example certainly does not quite look as ergonomic and clean, but the API needs to understand (a) which are all the calls we need to make and (b) the calls and their params (if required). So breaking it down -

 - `api.query.timestamp.now` - the timestamp is passed naked without any params. Also note that we do not call it while passing, but rather only provides a reference to the function, i.e. we do not have the expected `()` at the end. (This could also be of the form `[api.query.timestamp.now]`, aligning with subsequent entries)
- `[api.query.system.accountNonce, ADDR]` - the nonce query is passed as an array containing the function (once again naked), followed by the parameters that apply.

- **summary**: Set the balances of a given account.  This will alter `FreeBalance` and `ReservedBalance` in storage. it will also decrease the total issuance of the system (`TotalIssuance`). If the new free or reserved balance is below the existential deposit, it will reset the account nonce (`system::AccountNonce`).  The dispatch origin for this call is `root`.  # <weight> - Independent of the arguments. - Contains a limited number of reads and writes. # </weight>
-
-▸ **transfer**(dest: `Address`, value: `Compact<Balance>`)
- **summary**: Transfer some liquid free balance to another account.  `transfer` will set the `FreeBalance` of the sender and receiver. It will decrease the total issuance of the system by the `TransferFee`. If the sender's account is below the existential deposit as a result of the transfer, the account will be reaped.  The dispatch origin for this call must be `Signed` by the transactor.  # <weight> - Dependent on arguments but not critical, given proper implementations for input config types. See related functions below. - It contains a limited number of reads and writes internally and no complex computation.  Related functions:  - `ensure_can_withdraw` is always called internally but has a bounded complexity. - Transferring balances to accounts that did not exist before will cause `T::OnNewAccount::on_new_account` to be called. - Removing enough funds from an account will trigger `T::DustRemoval::on_unbalanced` and `T::OnFreeBalanceZero::on_free_balance_zero`.  # </weight>

- **summary**: Instantiates a new contract from the `codehash` generated by `put_code`, optionally transferring some balance.  Instantiation is executed as follows:  - The destination address is computed based on the sender and hash of the code. - The smart-contract account is created at the computed address. - The `ctor_code` is executed in the context of the newly-created account. Buffer returned after the execution is saved as the `code` of the account. That code will be invoked upon any call received by this account. - The contract is initialized.

- **summary**: Set candidate approvals. Approval slots stay valid as long as candidates in those slots are registered.  Locks `value` from the balance of `origin` indefinitely. Only [`retract_voter`] or [`reap_inactive_voter`] can unlock the balance.  `hint` argument is interpreted differently based on: - if `origin` is setting approvals for the first time: The index will be checked for being a valid _hole_ in the voter list. - if the hint is correctly pointing to a hole, no fee is deducted from `origin`. - Otherwise, the call will succeed but the index is ignored and simply a push to the last chunk with free space happens. If the new push causes a new chunk to be created, a fee indicated by [`VotingFee`] is deducted. - if `origin` is already a voter: the index __must__ be valid and point to the correct position of the `origin` in the current voters list.  Note that any trailing `false` votes in `votes` is ignored; In approval voting, not voting for a candidate and voting false, are equal.  # <weight> - O(1). - Two extra DB entries, one DB change. - Argument `votes` is limited in length to number of candidates. # </weight>

-▸ **bondExtra**(max_additional: `Compact<BalanceOf>`)
- **summary**: Add some extra amount that have appeared in the stash `free_balance` into the balance up for staking.  Use this if there are additional funds in your stash account that you wish to bond. Unlike [`bond`] or [`unbond`] this function does not impose any limitation on the amount that can be added.  The dispatch origin for this call must be _Signed_ by the stash, not the controller.  # <weight> - Independent of the arguments. Insignificant complexity. - O(1). - One DB entry. # </weight>

The dispatch origin for this call must be _Signed_ by the controller, not the stash.  # <weight> - The transaction's complexity is proportional to the size of `targets`, which is capped at `MAX_NOMINATIONS`. - Both the reads and writes follow a similar pattern. # </weight>
-
-▸ **setController**(controller: `Address`)
- **summary**: (Re-)set the controller of a stash.  Effects will be felt at the beginning of the next era.  The dispatch origin for this call must be _Signed_ by the stash, not the controller.  # <weight> - Independent of the arguments. Insignificant complexity. - Contains a limited number of reads. - Writes are limited to the `origin` account key. # </weight>

-
-▸ **setValidatorCount**(new: `Compact<u32>`)
- **summary**: The ideal number of validators.
-
-▸ **unbond**(value: `Compact<BalanceOf>`)
- **summary**: Schedule a portion of the stash to be unlocked ready for transfer out after the bond period ends. If this leaves an amount actively bonded less than T::Currency::minimum_balance(), then it is increased to the full amount.  Once the unlock period is done, you can call `withdraw_unbonded` to actually move the funds out of management ready for transfer.  No more than a limited number of unlocking chunks (see `MAX_UNLOCKING_CHUNKS`) can co-exists at the same time. In that case, [`Call::withdraw_unbonded`] need to be called first to remove some of the chunks (if possible).  The dispatch origin for this call must be _Signed_ by the controller, not the stash.  See also [`Call::withdraw_unbonded`].  # <weight> - Independent of the arguments. Limited but potentially exploitable complexity. - Contains a limited number of reads. - Each call (requires the remainder of the bonded balance to be above `minimum_balance`) will cause a new entry to be inserted into a vector (`Ledger.unlocking`) kept in storage. The only way to clean the aforementioned storage item is also user-controlled via `withdraw_unbonded`. - One DB entry. </weight>
-
-▸ **validate**(prefs: `ValidatorPrefs`)
- **summary**: Declare the desire to validate for the origin controller.  Effects will be felt at the beginning of the next era.  The dispatch origin for this call must be _Signed_ by the controller, not the stash.  # <weight> - Independent of the arguments. Insignificant complexity. - Contains a limited number of reads. - Writes are limited to the `origin` account key. # </weight>
-
-▸ **withdrawUnbonded**()
- **summary**: Remove any unlocked chunks from the `unlocking` queue from our management.  This essentially frees up that balance to be used by the stash account to do whatever it wants.  The dispatch origin for this call must be _Signed_ by the controller, not the stash.  See also [`Call::unbond`].  # <weight> - Could be dependent on the `origin` argument and how much `unlocking` chunks exist. It implies `consolidate_unlocked` which loops over `Ledger.unlocking`, which is indirectly user-controlled. See [`unbond`] for more detail. - Contains a limited number of reads, yet the size of which could be large based on `ledger`. - Writes are limited to the `origin` account key. # </weight>

Further, the `OnFreeBalanceZero` callback is invoked, giving a chance to external modules to clean up data associated with the deleted account.  `system::AccountNonce` is also deleted if `ReservedBalance` is also zero (it also gets collapsed to zero if it ever becomes less than `ExistentialDeposit`.

When this balance falls below the value of `ExistentialDeposit`, then this 'reserve account' is deleted: specifically, `ReservedBalance`.  `system::AccountNonce` is also deleted if `FreeBalance` is also zero (it also gets collapsed to zero if it ever becomes less than `ExistentialDeposit`.)

-▸ **digest**(): `DigestOf`
- **summary**: Digest of the current block, also part of the block header.
-
-▸ **eventCount**(): `EventIndex`
- **summary**: The number of events in the `Events<T>` list.
-
-▸ **events**(): `Vec<EventRecord>`
- **summary**: Events deposited for the current block.
-
-▸ **eventTopics**(`Null, Hash`): `Vec<(BlockNumber,EventIndex)>`
- **summary**: Mapping between a topic (represented by T::Hash) and a vector of indexes of events in the `<Events<T>>` list.  The first key serves no purpose. This field is declared as double_map just for convenience of using `remove_prefix`.  All topic vectors have deterministic storage locations depending on the topic. This allows light-clients to leverage the changes trie storage tracking mechanism and in case of changes fetch the list of events of interest.  The value has the type `(T::BlockNumber, EventIndex)` because if we used only just the `EventIndex` then in case if the topic has the same contents on the next block no notification will be triggered thus the event might be lost.
-
-▸ **extrinsicCount**(): `Option<u32>`
- **summary**: Total extrinsics count for the current block.
-
-▸ **extrinsicData**(`u32`): `Bytes`
- **summary**: Extrinsics data for the current block (maps an extrinsic's index to its data).
-
-▸ **extrinsicsRoot**(): `Hash`
- **summary**: Extrinsics root of the current block, also part of the block header.
-
-▸ **nextWeightMultiplier**(): `WeightMultiplier`
- **summary**: The next weight multiplier. This should be updated at the end of each block based on the saturation level (weight).
-
-▸ **number**(): `BlockNumber`
- **summary**: The current block number being processed. Set by `execute_block`.
-
-▸ **parentHash**(): `Hash`
- **summary**: Hash of the previous block.
-
-▸ **randomMaterial**(): `(i8,Vec<Hash>)`
- **summary**: Series of block headers from the last 81 blocks that acts as random seed material. This is arranged as a ring buffer with the `i8` prefix being the index into the `Vec` of the oldest hash.
