# [unreleased]

## Added

- Added `params::WritableToBeBytes::to_vec`.
- New `ComponentId` (`u64` typedef for now) which replaces former `TargetId` as a generic
  way to identify components.
- Various abstraction and objects for targeted requests. This includes mode request/reply
  types for actions, HK and modes.
- `VerificationReportingProvider::owner_id` method.
- Introduced generic `EventMessage` which is generic over the event type and the additional
  parameter type. This message also contains the sender ID which can be useful for debugging
  or application layer / FDIR logic.

## Changed

- `encoding::ccsds::PacketIdValidator` renamed to `ValidatorU16Id`, which lives in the crate root.
  It can be used for both CCSDS packet ID and CCSDS APID validation.
- `EventManager::try_event_handling` not expects a mutable error handling closure instead of
  returning the occured errors.
- Renamed `EventManagerBase` to `EventReportCreator`
- Renamed `VerificationReporterCore` to `VerificationReportCreator`.
- Removed `VerificationReporterCore`. The high-level API exposed by `VerificationReporter` and
  the low level API exposed by `VerificationReportCreator` should be sufficient for all use-cases.
- 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.
- Renamed `WritableToBeBytes::raw_len` to `WritableToBeBytes::written_len` for consistency.
- `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.
- Major overhaul of the PUS handling module.
- Replace `TargetId` by `ComponentId`.
- Replace most usages of `ChannelId` by `ComponentId`. A dedicated channel ID has limited usage
  due to the nature of typed channels in Rust.
- `CheckTimer` renamed to `CountdownProvider`.
- Renamed `TargetId` to `ComponentId`.
- Replaced most `ChannelId` occurences with `ComponentId`. For typed channels, there is generally
  no need for dedicated channel IDs.
- Changed `params::WritableToBeBytes::raw_len` to `written_len` for consistency.
- `EventReporter` caches component ID.
- Renamed `PusService11SchedHandler` to `PusSchedServiceHandler`.
- Fixed general naming of PUS handlers from `handle_one_tc` to `poll_and_handle_next_tc`.
- Reworked verification module: The sender (`impl EcssTmSenderCore`)
  now needs to be passed explicitely to the `VerificationReportingProvider` abstraction. This
  allows easier sharing of the TM sender component.

## Fixed

- Update deprecated API for `PusScheduler::insert_wrapped_tc_cds_short`
  and `PusScheduler::insert_wrapped_tc_cds_long`.
- `EventReporter` uses interior mutability pattern to allow non-mutable API.

## Removed

- Remove `objects` module.

# [v0.2.0-rc.0] 2024-02-21

## Added

- New PUS service abstractions for HK (PUS 3) and actions (PUS 8). Introducing new abstractions
  allows to move some boilerplate code into the framework.
- New `VerificationReportingProvider` abstraction to avoid relying on a concrete verification
  reporting provider.

## Changed

- Verification reporter API timestamp arguments are not `Option`al anymore. Empty timestamps
  can be passed by simply specifying the `&[]` empty slice argument.

# [v0.1.1] 2024-02-12

- Minor fixes for crate config `homepage` entries and links in documentation.

# [v0.1.0] 2024-02-12

Initial release.
