   It is superseded by the :c:macro:`NRF_802154_CCA_ED_THRESHOLD_DBM_DEFAULT` macro, which specifies the absolute value of the CCA ED threshold in dBm. (KRKNWK-19974)
 * The Energy Detection (ED) sample, Received Signal Strength Indicator (RSSI), and Clear Channel Assessment (CCA) threshold now account for Low-Noise Amplifier (LNA) gain.
   These values now represent the power at the antenna connector, rather than at the radio. (KRKNWK-19974)
+* The reliability of timestamping on nRF52 and nRF53 Series SoCs was improved.
+  The driver no longer reports :c:macro:`NRF_802154_NO_TIMESTAMP` for received
+  frames and ACKs in rare cases. (KRKNWK-20539)

 For the SOCs equipped with a floating-point unit (nRF52840 and nRF52833), the service layer is available in the soft-float, softfp-float, and hard-float build versions.
 For the other SOCs/SiPs, it is available only in the soft-float build version.
