 ## Summary
 
-The main change in this release is the revamp of exception handling in general. New exceptions were created and `send()` now raises an exception too when it fails.
-
-Hopefully they are now used much more uniformly across the whole library.
+<!-- Here goes a general summary of what this release is about -->
 
 ## Upgrading
 
-* The `Sender.send()` method now `raise`s a `SenderError` instead of returning `False`. The `SenderError` will typically have a `ChannelClosedError` and the underlying reason as a chained exception.
-
-* The `Receiver.ready()` method (and related `receive()` and `__anext__` when used as an async iterator) now `raise`s a `ReceiverError` and in particular a `ReceiverStoppedError` when the receiver has no more messages to receive.
-
-  `Receiver.consume()` doesn't raise any exceptions.
-
-  Receivers raising `EOFError` now raise `ReceiverInvalidatedError` instead.
-
-* For channels which senders raise an error when the channel is closed or which receivers stop receiving when the channel is closed, the `SenderError` and `ReceiverStoppedError` are chained with a `__cause__` that is a `ChannelClosedError` with the channel that was closed.
-
-* `ChannelClosedError` now requires the argument `channel` (before it was optional).
-
-* Now exceptions are not raised in Receiver.ready() but in Receiver.consume() (receive() or the async iterator `anext`).
+<!-- Here goes notes on how to upgrade from previous versions, including if there are any depractions and what they should be replaced with -->
 
 ## New Features
 
-* New exceptions were added:
-
-  * `Error`: A base exception from which all exceptions from this library inherit.
-
-  * `SendError`: Raised for errors when sending messages.
-
-  * `ReceiverError`: Raised for errors when receiving messages.
+<!-- Here goes the main new features and examples or instructions on how to use them -->
 
-  * `ReceiverClosedError`: Raised when a receiver don't have more messages to receive.
+## Bug Fixes
 
-  * `ReceiverInvalidatedError`: Raised when a receiver was invalidated (for example it was converted into a `Peekable`).
+<!-- Here goes notable bug fixes that are worth a special mention or explanation -->
