[CIP-1854]: https://github.com/cardano-foundation/CIPs/blob/master/CIP-1854/CIP-1854.md
## [3.5.0] - 2021-06-28
### Added
- Initial release of a [NPM Package](https://www.npmjs.com/package/cardano-addresses)
which uses the GHCJS build.
### Changed
- The supported compiler version is now GHC 8.10.4.
- Updated `validateScriptTemplate` and `validateScriptOfTemplate`
functions for multi-signature wallets.
## [3.4.0] - 2021-04-30
### Added
- Added `Cardano.Address.Style.Shelley.eitherInspectAddress` function
with stronger result and error types.
- Added `Cardano.Address.Style.Shared` module which defines a shared
wallet style enabling multisig.
### Changed
- The constructors of `Cardano.Address.Style.Shelley.ErrInspectAddress`
have changed.
Any code which pattern matches on this type will need minor changes.
- A number of Bech32 prefixes were changed to account for CIP changes.
The whole family of `*_shared_*` prefixes were introduced to accommodate
newly added shared wallet style. In specific, there in no longer `script_vkh`
but `addr_shared_vkh` and `stake_shared_vkh` to denote spending and stake
verification key hashes, respectively.
- `KeyHash` now needs `KeyRole` values to be specified, except binary
payload. It was needed change to enable differentiating between
spending and stake key hashes.
### Removed
- Multisig related functions were deleted from `Cardano.Address.Style.Shelley` as they
found a new place in `Cardano.Address.Style.Shared`.
## [3.3.0] - 2021-04-09
### Added
- The library now builds with ghcjs and passes tests running on nodejs.
- The `cardano-address inspect` command now includes bech32
encodings. In the output, the JSON attribute will have a `_bech32`
suffix. For example, `stake_key_hash_bech32`.
### Changed
- The `Index` type no longer has an `Enum` instance. Use
`indexFromWord32` and `indexToWord32` instead.
- (Breaking change) The `Cardano.Address.bech32` function will now use
the `addr_test` prefix instead of `addr`, if the given address is
not a mainnet address.

## [3.2.0] - 2020-01-22
### Added
- Added definition for 'Cosigner'.
- Added definition for 'ScriptTemplate', `ToJSON` and `FromJSON` instances added.
- Added validation of 'ScriptTemplate'.
- Added command-line for 'cardano-address script validate'
- Introduced 'foldScript' function.
### Changed
- Fixed `cardano-address --version` reporting.
- Added Ord instance for 'ScriptHash'.
- Extended script to account for ActiveFromSlot and ActiveUntilSlot, ie., introducing timelocks. `ToJSON` and `FromJSON` instances were updated. Also command-line supports
timelocks now via 'active_from' and 'active_until`.
- Introduced Required and Recommended validation and adjusted the current one.
- Fixed cardano-address address bootstrap example in command-line help.
- Add missing crc32 integrity check when decoding Byron/Icarus addresses.
- Parametrized 'Script', and use it with 'ScriptHash' and 'Cosigner'.

- Correcting cardano-address hash example in command-line help.
- Adding more examples to README.md

## [3.1.0] - 2020-11-13
### Added
N/A
### Changed
- 'keyHashFromText' now works seamlessly with key, extended keys or key hashes. In case a key or extended key is given, the relevant part will be hashed on the fly. Said differently, it means that
the command-line and the JSON instance for 'Script' works transparently with keys or key hashes.
- Fixed a bug with the `key hash` command which failed when provided with extended keys.
- The 'FromJSON' instance for 'Script' now runs the validation within the JSON parser, such that when the parser succeeds the resulting 'Script' is indeed valid.
- The 'FromJSON' instance for 'Script' is now much better at showing errors.
### Removed
N/A
## [3.0.0] - 2020-11-12
### Added
- Support for (multisig) scripts and script addresses in modules:
- `Cardano.Address.Script`
- `Cardano.Address.Script.Parser`
- Support for constructing scripts and script addresses via the command-line.
- Support for constructing rewards addresses via the library and command-line.
- New command for computing key and script hashes that are required in the construction of larger objects (e.g. addresses).
- Support for cabal build.
### Changed
- The command-line API no longer support multi-encoding (base16, bech32 and base58) but instead, enforces bech32 for keys and addresses, with specific human readable prefixes. It is still possible to easily go from base16-encoded data to bech32 by piping data through the [`bech32`](https://github.com/input-output-hk/bech32/) command-line.
- It is no longer possible to derive child keys to and from any path. Are only allowed:
- root -> account
- root -> address
- account -> address
This is reflected in the bech32 prefixes of the inputs and outputs.
- Allow constructing delegation addresses from a script. This works transparently from previous version of the command-line, but the command now also accepts script hashes as possible valid inputs.
### Removed
- No more `--legacy` option on the `key child` command. Which derivation scheme to use is now inferred from the bech32 prefixe used and the derivation path.
- `Cardano.Address.Errors` module. Errors data-types have been moved to their respective module `Cardano.Address.Styles.{Byron,Icarus,Shelley}`
- Anything related to Jormungandr in both the library and the command-line.
## [2.1.0] - 2020-09-29
### Added
- Added constructors to derive keys on the multisig role.
- Made the parser for `--network-tag` more user friendly by now accepting pre-defined keywords such as "mainnet" or "testnet".
### Changed
- Renamed `AccountingStyle` into `Role` to better capture the semantic of the 4th level in derivation paths.
- Made script hashes 28-byte long again, after this was fixed upstream in the Cardano ledger.
### Removed
N/A
## [2.0.0] - 2020-09-10
