=======

* The Channel Sounding feature is now :ref:`supported <nrf:software_maturity>` instead of experimental. (DRGN-24060)

* The LE Channel Selection Algorithm event is no longer raised when a connection was established as a peripheral using legacy advertising commands. (DRGN-24660)

This behavior was changed to accommodate ES-27170.

* The CIS or BIS sink now generate lost SDUs immediately when scheduling conflicts occur instead of after receiving the next valid SDU. (DRGN-24062)

* The data length is not updated

* Fixed an issue where the central would disconnect without sending a ``LL_TERMINATE_IND`` when the user sent the Disconnect HCI command.

This issue occurred when the central was blocked by another higher-priority role for extended periods. (DRGN-24784)

* Fixed a rare assert when stopping a CIG or BIG.

This issue would only occur when another CIG or BIG role was active at the same time. (DRGN-24938)

* Fixed a rare issue where the controller running on an nRF54 Series device would send a corrupted packet with a valid CRC.

This could lead to sending a packet with an invalid MIC in the case of an encrypted connection. (DRGN-24929)

The issue would occur if the :kconfig:option:`CONFIG_FPU` and :kconfig:option:`CONFIG_FPU_SHARING` Kconfig options are enabled.
