 # [unreleased]
 
+## Changed
+
+- Refactored `EventManager` to heavily use generics instead of trait objects.
+  - `SendEventProvider` -> `EventSendProvider`. `id` trait method renamed to `channel_id`.
+  - `ListenerTable` -> `ListenerMapProvider`
+  - `SenderTable` -> `SenderMapProvider`
+  - There is an `EventManagerWithMpsc` and a `EventManagerWithBoundedMpsc` helper type now.
+- Refactored ECSS TM sender abstractions to be generic over different message queue backends.
+- Refactored Verification Reporter abstractions and implementation to be generic over the sender
+  instead of using trait objects.
+- `PusServiceProvider` renamed to `PusServiceDistributor` to make the purpose of the object
+  more clear
+- `PusServiceProvider::handle_pus_tc_packet` renamed to `PusServiceDistributor::distribute_packet`.
+- `PusServiceDistibutor` and `CcsdsDistributor` now use generics instead of trait objects.
+  This makes accessing the concrete trait implementations more easy as well.
+
+## Fixed
+
+- Update deprecated API for `PusScheduler::insert_wrapped_tc_cds_short`
+  and `PusScheduler::insert_wrapped_tc_cds_long`.
