  - Added mavlink tcp proxy. Now it is possible to use backup link via LTE modem or connect onboard computer without external mavlink-router.
    To connect as backup link in QGC use tcp connection to port 5760 and check "high latency link" checkbox.
 
- - Self-injected frames are ingnored now in case when TX and RX use the same radio port.
+ - Self-injected frames are ignored now in case when TX and RX use the same radio port.
  - Added cross-build support via qemu + docker.
  - Improved udp socket buffer overflow handling:

  - Large refactoring of WFB-ng control-plane:
 
     1. Added support for multiple profiles and profile inheritance (no need to have multiple copies of wifibroadcast.cfg).
-    2. No hadcoded streams (video/mavlink/tunnel) anymore. You can define own profiles and any number of data streams can be added/removed to profiles without any code change.

     3. Multiple profiles can be active simultaneously (no need to run multiple instances of wfb-server when using the same wifi adapters for different links). For example: `systemctl enable wifbroadcast@gs1:gs2:gs3:gs4`
     4. Added support for raw udp data streams. They don't use any frame aggregation or mavlink injection.
     5. TX antenna selection is now `link_domain` wide - for example one-way `udp_proxy` TX will use active antenna selected by other RX streams.
     6. Added mirror mode. Use it only if you use different frequency channels for multiple cards. In this mode each packet will be send via all cards (by default only active cards send packets). This allow to add redundancy for multi-frequency link
 
     Compatibility:
     This commit maintain both radio and config compatibility with previous version.
-    So you can use previous verion of wfb-ng on the other link side and import most of your customizations from /etc/wifibroadcast.cfg

     The only config incompatible change is that `common.link_id` was moved to profile section and renamed to `link_domain`.
 
  - Added support for multiple directed antennas on both ends and different frequency channels on different cards:
