 ## [Unreleased]

+
+### Added
+
+- Group storage: group metadata is now stored in a local cache, to avoid issuing an API call whenever 
+  group details need to be looked up. (#88)
+- Optional desktop notifications in CLI. (#85)
+- Add function to clear messages only. (#115)
+
+### Fixed
+
+- Fix get contact by ID method. (#91)
+- Fix the key used when storing messages. (#111)
+- Fix unlink when clearing store. (#112)
+
 ### Changed
 
+- Improve sending messages speed by updating `libsignal-service-rs` and using its websocket in duplex mode (#92). Because of this change, polling on the stream returned by `Manager::receive_messages` is now required to send messages.
 - Only `DataMessage` that are sent, received, or sent from another device are saved in the local store (#137).
-  This is a breaking change because clients previously had to introduce calls to filter internal messages themselves.
-
 - Changed (and fixed) the behaviour of the iterator returned by `SledStore::messages` (#119)
-  * The iterator yields elements in chronological order (used to be reversed)
-  * The iterator now implements `DoubleEndedIterator` which means you it can be reversed or consumed from the end
-  * The method now accepts the full range syntax, like `0..=1678295210` or `..` for all messages

+- Wait for contacts sync to be received and processed when linking as secondary device. (#106)
