 The STM32F3-Discovery device was picked because it is a cheap Cortex-M4 based device which is also
 used by the [Rust Embedded Book](https://docs.rust-embedded.org/book/intro/hardware.html) and the
 [Rust Discovery](https://docs.rust-embedded.org/discovery/f3discovery/) book as an introduction
 to embedded Rust.

-If you would like to use a custom GDB application, you can specify the gdb binary in the following
-configuration variables in your `settings.json`:
-
-- `"cortex-debug.gdbPath"`
-- `"cortex-debug.gdbPath.linux"`
-- `"cortex-debug.gdbPath.windows"`
-- `"cortex-debug.gdbPath.osx"`
-
 ## Commanding with Python
 
 When the SW is running on the Discovery board, you can command the MCU via a serial interface,
-using COBS encoded CCSDS packets.
- 
-TODO:
-  - How and where to connect serial interface on the MCU
-  - How to set up Python venv (or at least strongly recommend it) and install deps
-  - How to copy `def_tmtc_conf.json` to `tmtc_conf.json` and adapt it for custom serial port
+using COBS encoded PUS packets.
+
+It is recommended to use a virtual environment to do this. To set up one in the command line,
+you can use `python3 -m venv venv` on Unix systems or `py -m venv venv` on Windows systems.
+After doing this, you can check the [venv tutorial](https://docs.python.org/3/tutorial/venv.html)
+on how to activate the environment and then use the following command to install the required
+dependency:
+
+```sh
+pip install -r requirements.txt
+```
+
+The packets are exchanged using a dedicated serial interface. You can use any generic USB-to-UART
+converter device with the TX pin connected to the PA3 pin and the RX pin connected to the PA2 pin.
+
+A default configuration file for the python application is provided and can be used by running
+
+```sh
+cp def_tmtc_conf.json tmtc_conf.json
+```
+
+After that, you can for example send a ping to the MCU using the following command
+
+```sh
+./main.py -p /ping
+```
+
+You can configure the blinky frequency using
+
+```sh
+./main.py -p /change_blink_freq
+```
+
+All these commands will package a PUS telecommand which will be sent to the MCU using the COBS
+format as the packet framing format.

+/// This is a generic handler class for all PUS services where a PUS telecommand is converted

+///
+/// The generic steps for this process are the following
+///
+///  1. Poll for TC packets
+///  2. Convert the raw packets to a [PusTcReader].
+///  3. Convert the PUS TC to a typed request using the [PusTcToRequestConverter].
+///  4. Route the requests using the [GenericRequestRouter].
+///  5. Add the request to the active request map using the [ActiveRequestMapProvider] abstraction.
+///  6. Check for replies which complete the forwarded request. The handler takes care of
+///     the verification process.
+///  7. Check for timeouts of active requests. Generally, the timeout on the service level should
+///     be highest expected timeout for the given target.
+///
+/// The handler exposes the following API:
+///
+///  1. [Self::poll_and_handle_next_tc] which tries to poll and handle one TC packet, covering
+///     steps 1-5.
+///  2. [Self::poll_and_check_next_reply] which tries to poll and handle one reply, covering step 6.
+///  3. [Self::check_for_request_timeouts] which checks for request timeouts, covering step 7.

 # [unreleased]
 
+# [v0.2.0] 2024-05-02
+
+## Changed
+
+- Various improvements for the PUS stack components.
+
+## Added
+
+- Added `HandlingStatus` enumeration.
+
+# [v0.2.0-rc.5] 2024-04-24
+
+## Added
+
+- Optional `defmt::Format` support for the event types, if the `defmt` feature is activated.
+
+## Changed
+
+- Removed `MpscEventReceiver`, the `EventReceiveProvider` trait is implemented directly
+  on `mpsc::Receiver<EventMessage<Event>>`
+- Renamed `PusEventDispatcher` to `PusEventTmCreatorWithMap`.
+- Renamed `DefaultPusEventU32Dispatcher` to `DefaultPusEventU32EventCreator`.
+- Renamed `PusEventMgmtBackendProvider` renamed to `PusEventReportingMap`.
+- Reanmed Event `const_new` methods to `new` and the former `new` methods to `new_checked`
+
+# [v0.2.0-rc.4] 2024-04-23
+
+## Changed
+
+- The `parse_for_ccsds_space_packets` method now expects a non-mutable slice and does not copy
+  broken tail packets anymore. It also does not expect a mutable `next_write_idx` argument anymore.
+  Instead, a `ParseResult` structure is returned which contains the `packets_found` and an
+  optional `incomplete_tail_start` value.
+
+## Fixed
+
+- `parse_for_ccsds_space_packets` did not detect CCSDS space packets at the buffer end with the
+  smallest possible size of 7 bytes.
+- TCP server component now re-registers the internal `mio::Poll` object if the client reset
+  the connection unexpectedly. Not doing so prevented the server from functioning properly
+  after a re-connect.
+
+# [v0.2.0-rc.3] 2024-04-17
+
+docs-rs hotfix 2
+
+# [v0.2.0-rc.2] 2024-04-17
+
+docs-rs hotfix
+
+# [v0.2.0-rc.1] 2024-04-17
+
+- `spacepackets` v0.11
+
+## 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.
+- Stop signal handling for the TCP servers.
+- TCP server now uses `mio` crate to allow non-blocking operation. The server can now handle
+  multiple connections at once, and the context information about handled transfers is
+  passed via a callback which is inserted as a generic as well.
+
+## Changed
+
+- Renamed `ReceivesTcCore` to `PacketSenderRaw` to better show its primary purpose. It now contains
+  a `send_raw_tc` method which is not mutable anymore.
+- Renamed `TmPacketSourceCore` to `TmPacketSource`.
+- Renamed `EcssTmSenderCore` to `EcssTmSender`.
+- Renamed `StoreAddr` to `PoolAddr`.
+- Reanmed `StoreError` to `PoolError`.
+- TCP server generics order. The error generics come last now.
+- `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.
+- Removed CCSDS and PUS distributor modules. Their worth is questionable in an architecture
+  where routing traits are sufficient and the core logic to demultiplex and distribute packets
+  is simple enough to be application code.
+
