- Make connectionQueue(), latestTransmissionOutcomes() and latestTransmissionSuccessful() methods static in order to match the underlying data storage.

- Make it possible to transfer elements directly between connectionQueues.

- Add defaultBSSID value.

- Fix bug where encrypted Espnow-connections expired 1 ms too late.

- Add MutexTracker::captureBan() functionality and use it in the espnowReceiveCallbackWrapper method to ensure a consistent mutex environment there.

- Rename acceptRequest to acceptRequests since several requests can be accepted, not just one.

- Reorganize EspnowMeshBackend.cpp.

- Split sendEspnowResponses() method into sendEspnowResponses() and sendPeerRequestConfirmations().

- Add sendStoredEspnowMessages() method to provide the same functionality as the previous version of sendEspnowResponses().

- Add logic for handling peerRequestConfirmations received at the same time as a peer request is being made, to avoid lockups when there are simultaneous cyclic peer requests.

- Add logic for handling simultaneous reciprocal peer requests.

- Include MAC addresses in HMAC calculations for peer requests and use HMAC for all unencrypted peer request messages, to make sure we receive valid MAC combinations.

- Add asserts to ensure ESP-NOW encryption integrity during code changes.

- Add estimatedMaxDuration argument to performEspnowMaintainance and related methods.

- Add methods to EncryptedConnectionData for setting peer MAC.

- Remove createEncryptionRequestMessage function from JsonTranslator since it is not used, to increase clarity.

- Add encryptedConnectionsSoftLimit() and related functionality.

- Add mutex to protect connectionQueue usage during attemptTransmission.

- Add _ongoingPeerRequestMac variable.

- Add reservedEncryptedConnections() method.

- Add TransmissionOutcomesUpdateHook() callback.

- Add constConnectionQueue() method to allow connectionQueue usage while connectionQueue mutex is active.

- Rearrange attemptAutoEncryptingTransmission argument order to increase efficiency.

- Add functionality for serializing the unencrypted ESP-NOW connection.

- Add some constness.

- Improve comments.

- Improve documentation.

- Update keywords.txt.
