nRF Connect SDK v1.9.0 - nRF 802.15.4 Radio Driver 

Delayed transmission and reception feature support for nRF5340. (KRKNWK-12074)
Backforwarding of transmitted frames to support retransmissions through serialization for nRF5340. (KRKNWK-10114)
Serialization of API required by Thread 1.2 (KRKNWK-12077) and other API for nRF5340.

Fixed an issue where interleaving transmissions of encrypted and unencrypted frames could cause memory corruption. (KRKNWK-12261)
Fixed an issue where interruption of a reception of encrypted frame could cause memory corruption. (KRKNWK-12622)
Fixed an issue where transmission of an encrypted frame could transmit a frame filled partially with zeros instead of proper ciphertext. (KRKNWK-12770)
Fixed stability issues related to CSMA-CA occurring with enabled experimental coexistence feature from Multiprotocol Service Layer. (KRKNWK-12701)

Incoming frames with Header IEs present but with no payload IEs and with no payload do not need IE Termination Header provided anymore. (KRKNWK-11875)

Fixed an issue where the notification queue would be overflowed under stress. (KRKNWK-11606)
Fixed an issue where nrf_802154_transmit_failed callout would not always correctly propagate the frame properties. (KRKNWK-11605)

Modified the 802.15.4 Radio Driver Transmit API. It now allows specifying whether to encrypt or inject dynamic data into the outgoing frame, or do both. The nrf_802154_transmitted_frame_props_t type is used for this purpose.

Fixed an issue where it would not be possible to transmit frames with invalid Auxiliary Security Header if CONFIG_NRF_802154_ENCRYPTION was set to n. (KRKNWK-11218)
Fix an issue with the IE Vendor OUI endianness. (KRKNWK-10633)
Fixed various bugs in the MAC Encryption layer. (KRKNWK-10646)

Application and device drivers (excluding those compliant with Multiprotocol Service Layer) must not use IRQ priority higher than NRF_802154_SWI_PRIORITY and NRF_802154_SL_RTC_IRQ_PRIORITY.
Transmitting an 802.15.4 frame with improperly populated Auxiliary Security Header field might result in assert. Make sure that you populate the Auxiliary Security Header field according to the IEEE Std 802.15.4-2015 specification, section 9.4.

Initial common release.

The release notes of the legacy versions of the Radio Driver are available in the Radio Driver section of the Infocenter.
The changelog of the previous versions of the 802.15.4 SL library is now located at the bottom of this page.
The Radio Driver documentation will now also include the Service Layer documentation.
Future versions of the Radio Driver and the Service Layer will follow NCS version tags.
The 802.15.4 Radio Driver API has been modified to support more than a single delayed reception window simultaneously. The nrf_802154_receive_at(), nrf_802154_receive_at_cancel(), and nrf_802154_receive_failed() functions take an additional parameter that identifies a given reception window unambiguously.

Added the possibility to check the 802.15.4 capabilities. Built from commit 2966ae8b4b3fcf2b64d8b987703cbf4ecc0dd60b.

Added multiprotocol support for the nRF53 family. Built from commit 5d2497b78683687bdd57fcd6854b1bc3c26871be.

PA/LNA implementation has been moved to MPSL. Obsolete implementation and API have been removed.

Removed PA/LNA implementation and API. Built from commit e268db75108016ee02965556aa52cf8437f5e071.

Initial release.

Added the libnrf_802154_sl.a library. Built from commit 4c5ff68c4eb4ba817774bbd6c711a67dfde7d905.
