2. for MAP, when its client leaves, always post SYSTEM_EVENT_AP_STADISCONNECTED to mesh layer regardless of whether the client has passed the encrypted authentication or not.
1. detect and fix root conflicts when router BSSID is not set.
2. 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.

4. fix routing table redundant issue.
5. modify the max routes limitation from 300 to 1000.
6. wifi: fix ap does not deauth sta which has not completed the 4-way handshake.

3. for root, modify the active scan time to 120ms.
4. remove all rc when clear parent Wi-Fi configuration.
5. fix error in checking Wi-Fi commit ID.
1. add network channel switch function.
- users can obtain the new channel through the event MESH_EVENT_CHANNEL_SWITCH.
- the entire network will be moved to the same channel as the router without user intervention.
- if no router is in the network, users can call esp_mesh_switch_channel() on the root side to
move the entire network to their desired channel.
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.
- if the channel is not specified, this value will be ignored.
- if the channel is specified and this value is set, when "fail" (mesh_attempts_t) times of parent selection
or look for networks are reached, device will change to perform a full channel scan for networks that could join.
- if the channel is specified and this value is set to 0, when a root is not elected, channel switch is not allowed.
but when a root appears, the root performs a full channel scan during the process of connecting to the router,
so even allow_channel_switch is set to 0, the root may still switch channel and eventually the entire network
changes channel.
5. add allow_router_switch to mesh router configuration.
- if the BSSID of router is not specified, this value will be ignored.
- if the BSSID of router is specified and this value is set, when the router of this specified BSSID fails to be found
after "fail" (mesh_attempts_t) times, the entire network is allowed to switch to another router with the same SSID.
6. modify the root to perform a full channel scan when esp_wifi_connect().
7. support handling beacon without DS Paramter Set.
1. fix failture of mesh stop caused by block-sending.
2. fix when FIXED_ROOT is set, 2nd layer devices can not receive mesh event ESP_ERR_MESH_NO_PARENT_FOUND.
3. fix when FIXED_ROOT is set and the root turns off mesh function, 2nd layer devices do not look for new parents.
4. add APIs esp_mesh_disconnect() and esp_mesh_connect().
5. disconnect from parent/router when the DSSS channel in received beacon is different from the home channel.
6. remove nvs task to release 3k bytes memory.
1. fix ap_loss that occurs when the parent turns off the mesh function and becomes a normal WiFi with a different SSID.
2. add an event MESH_EVENT_NETWORK_STATE that contains information about whether there is a root in the current network.
3. modify the mechanism of mesh IE update.
4. fix a problem in the process of re-voting to select the root, the device that does not meet the conditions of being a root votes for itself.
5. fix an issue that occurs in esp_mesh_recv_toDS() when stopping the mesh.
6. when the user specifies a parent for the device, the device will set the authmode and password of its AP mode to the same value as the specified parent.
7. add two disconnected reason codes MESH_REASON_EMPTY_PASSWORD and MESH_REASON_PARENT_UNENCRYPTED.
1. suppport mesh type, mesh ID, router and IE crypt func&key at any time after mesh is initalized.
2. support modify parent at any time after mesh is configured.
3. modify manual networking example.
4. update header file.
5. fix issues in root conflicts handling.
6. add max length of beacon to menuconfig.
7. fix issue when received a beacon without DSSS.
1. new APIs: esp_mesh_get_subnet_nodes_num() and esp_mesh_get_subnet_nodes_list().
2. fix hard to find the parent during connect.
3. disable Wi-Fi channel switch function.
4. fix a typo of MESH_EVENT_NO_PARENT_FOUND.
1. modify parent switch mechanism.
2. fix non-root doesn't clear the layer value in nvs.
3. fix retransmit the remove announcement packets.
4. add API esp_mesh_flush_upstream_packets().
5. automatically adjust passsive scan time based on the change of beacon interval.
1. add APIs to set/get announce interval values.
2. add API to enable/disable the min rate to 6Mbps for data packages.
3. add APIs to set/get RSSI threshold values.
4. fix ap_loss.
1. add mesh_assoc_t to esp_mesh_internal.h file.
2. rename "node" to "device" in esp_mesh.h.
3. add MESH_EVENT_SCAN_DONE event.
4. add APIs esp_mesh_scan_get_ap_record() and esp_mesh_scan_get_ap_ie_len() to get scan results.
5. modify API esp_mesh_set_self_organized() by adding parameter "select_parent".
6. modify API esp_mesh_set_parent() by adding parameter "parent_mesh_id"
7. add manual networking example.
1. fix issues on sending beacon caused by too much tx retries on other packets.
2. modify not to scan if rc exists when connect.
3. modify scan dwell time to default 120ms fo root.
1. fix a bug in initliazing map beacon interval.
2. fix not send MESH_EVENT_ROUTING_TABLE_REMOVE when MESH_NWK_CHILD_DISCONNECTED.
3. fix a bug in returning roots ie len.
1. modify the discover retry backoff time from (2,4,8,16,32,60,60)s to (500m,1,2,4,8,15,15)s.
2. add DHCP_DOES_ARP_CHECK to menuconfig for users to specify if do a ARP check on the offered address.
If enable, one more second will be taken in obtaining IP address.
3. update wifi libs
