 ### This release breaks backward compatibility!
+From this version, only major releases might break backward compatibility.
+For 1.x minor versions, only `DeprecationWarning` will occur.
 
 ### Features
-- #140 Replace `aiohttp` with a non async http library (urllib and websockets)
-  - No more async keyword required
-  - If `async` mode is really being needed, look at `request_data_async.py` example
+- #140, !118: Replace `aiohttp` with non-asynchronous `http` and `ws` libraries: `urllib` and `websocket-client`:
+  - `async` and `await` keywords are no longer required
+  - In case you would like to keep your code asynchronous, check `request_data_async.py` example
 
-- #160 Include examples into Python package
-  - Read new examples usage documentation in `README.md`
+- #160, !134: Include `examples` into the Python package:
+  - Read new examples usage documentation in the `README.md`
   
-- #95 Remove `signatures` argument from all `__init__()`’s documents subclasses
-  - Document constructor is `Document(version: int, currency: str)`
-  - All `Document` subclasses can be signed when created with the optional `signing_key` argument
-  - #172 `version` is optional now and have a proper default per document type
-  - `currency` is optional now and have `G1_CURRENCY_CODENAME` by default
+- #95, !144: Remove `signatures` argument from all `__init__()`’s documents subclasses:
+  - `Document` constructor is `Document(version: int, currency: str)`
+  - All `Document` subclasses can be directly signed when the optional `signing_key` argument is passed
+  - #172 `version` argument is now optional and have a proper default value per document type
+  - `currency` argument is now optional and defaults to `G1_CURRENCY_CODENAME`
     
         signing_key: SigningKey = None,
         version: int = VERSION,
         currency: str = G1_CURRENCY_CODENAME,
     
-  - Add `Identity.from_lookup_response()` to simplify examples
-  - Refactor `Document.signatures` (List) as `Document.signature` (str)
-  - Set `time` argument optional in SimpleTransaction
+  - Introduce `Identity.from_bma_lookup_response()` to simplify examples
+  - Refactor `Document.signatures` `List` as `Document.signature` `str`
+  - `VerifyingKey.verify_document()` has been removed in favour of `Document.check_signature(pubkey)`
+  - Set `time` argument optional in `SimpleTransaction`
 
-- #173 Make Transaction easier with single and multi-sign
-  - Transaction(signing_keys: Optional[Union[SigningKey, List[SigningKey]]] = None) allows single signature or multi-signatures when created
-  - Transaction.sign() and multi_sign() add signature now to allow different key owner to sign additionally the Tx doc
-  - Transaction.check_signature() and check_signatures() are available
+- #173, !150, !156: Make Transaction easier with single and multi-sign:
+  - `Transaction(signing_keys: Optional[Union[SigningKey, List[SigningKey]]] = None)` allows single signature or multi-signatures when created
+  - `Transaction.sign()` and `multi_sign()` now append signature to allow different key owner to sign additionally the Tx doc
+  - Introduce `Transaction.check_signature()` and `check_signatures()`
 
-- #178 Make `membership_type` argument optional with value 'IN' by default 
+- #178, !152: `Membership`: Make `membership_type` argument optional defaulting to `IN`
 
-- #175 Rename `timestamp` and `blockstamp` attributes/arguments depending on the type
-  - `block_id` for `BlockID` type
+- #175, !155: Rename `timestamp` and `blockstamp` attributes and arguments depending on their content:
   - `timestamp` for time in seconds
+  - `block_id` for `BlockID` type
+  - `BlockUID` has been renamed to `BlockID` and `BlockID.block_uid()` to `get_block_id()` 
   
-- #139 Rename Endpoints attributes from server to host(name)
-  - Rename `ConnectionHandler.server` to `address`
+- #139, !149: Rename `Endpoints` attributes from `server` to `host`

+- #161, !142: Add DUBP Mnemonic example
 
-- #161, #168 Add DUBP Mnemonic example
+- #163, !137: `Revocation.from_signed_raw()` now stores the block ID into a `BlockID` object
