- Update to version 1.4.0
* Major improvements to the DSP and decoding engine - gives much
better decoding success rate, especially for weak transmissions
from distant aircraft.
* Each VDL2 channel is now processed in a separate thread, which
allows balancing the load onto multiple CPU cores.
* Fixed a nasty decoder bug which caused good frames to be
corrupted during decoding stage and therefore missed.
* Added CRC checking for ACARS messages. If there is a CRC
mismatch, the message will still be logged, but with an
appropriate warning.
* New StatsD metric avlc.msg.air2air - counts messages from
aircraft to aircraft (however strange it seems, such things
happen in real life).
* New StatsD metric decoder.errors.too_long - counts VDL2 bursts
dropped due to unreasonably large value in the length field.
* Due to changes in the decoding engine, the following StatsD
metric are now obsolete and have been removed:
avlc.errors.no_flag_start, avlc.errors.no_flag_end,
decoder.errors.no_preamble.
* Added --extended-header command line option which causes a few
decoder diagnostic parameters to be logged for each message.
Refer to the FAQ in README.md for description of the fields.
* Other minor bugfixes and improvements.
* C11-capable compiler is now required to build the program.
