satrs/CHANGELOG.md
View File

@ -18,6 +18,11 @@ and this project adheres to [Semantic Versioning](http://semver.org/).
- 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
