   * A new API for seeding the random number generator ``sd_rand_seed_set`` has been added (DRGN-25550).

+    The valid range is [50, 5500] µs. The enums can still be used for backwards compatibility.
+    The active notification distance is now from when the SoftDevice prepares to use the radio, and not the
