This brings many changes, including fixes for a couple of memory leaks, and improved interoperability with 802.11r. There are also many changes related to 802.11be, which is not enabled at this time. Fixed upstream: - 022-hostapd-fix-use-of-uninitialized-stack-variables.patch - 180-driver_nl80211-fix-setting-QoS-map-on-secondary-BSSs.patch - 993-2023-10-28-ACS-Fix-typo-in-bw_40-frequency-array.patch Switch PKG_SOURCE_URL to https, since http is not currently working.
