1. fix network channel switch function. 2. support not configuring the network channel. 3. support not configuring the router BSSID even if the router is hidden. 4. add allow_channel_switch to mesh configuration. 5. add allow_router_switch to mesh router configuration. 6. support handling beacon without IE of DS Parameter Set. 7. fix Wi-Fi RX fails in a specific scenario (update libphy.a). 8. fix STAs can not detect disconnection from AP when encrypt transmission is used. 9. fix can not find hidden APs. 10. for root, modify the active scan time to 120ms. 11. remove all rc when clear parent Wi-Fi configuration. 12. fix memory leak caused by the remove announcement being sent is not released when esp_mesh_stop() is called. 13. fix modify IE encrypt after mesh is started. 14. ignore esp_mesh_connect() if mesh automatic reconnection is enabled. 15. fix reason is cleared before vote is done. 16. fix issues in the example of manual_networking when mesh network is encrypted. 17. detect and fix root conflicts when router BSSID is not set. 18. when root can not connect to the router due to NO_MORE_STAS(reason code:5), root will stop re-connection and perform MESH_NWK_LOOK_FOR_NETWORK. 19. wifi: fix the disconnection caused by receiving a deauth frame from non-parent node during scanning. 20. fix routing table redundant issue due to the remove announcement is not 100% reliable. 21. modify the max routes limitation from 300 to 1000. 22. wifi: fix ap does not deauth the sta which has not yet completed the 4-way handshake but the max replay count is reached.
