HAProxy 2.2.2 was released on 2020/07/31. It added 16 new commits after version 

It fixes some bugs in the DNS part. First, Jérome fixed a possible NULL pointer 
dereference leading to a segfault when a server status is updated based on a 
name resolution if the corresponding DNS answer contains Additional records. He 
also fixed a parsing error if Authority records is found in a DNS answer. Now, 
Authority records are just ignored. Finally, a possible spinning loop in the do-
resolve action was fixed. If used in tcp-request content ruleset, it was 
possible to wake up the stream in loop if the inspect-delay timeout was reached 
on a do-resolve action because it failed to abort the resolution in this case.

A segfault during sending data to the server was fixed, with the help of Luke 
Seelenbinder and Sander Klein. For synchronous connect, it was possible to try 
sending data before attaching the mux on the connection. Now, before leaving 
connect_server(), if the connection is fully established, the mux is attached, 
if necessary.

Willy fixed a last minute bug in the order the mux and the transport layer are 
attached to the connection. The mux was installed before the transport layer, 
leading to a double subscribes for reveiving with two different subscribers. It 
is totally unexpected and one event may be lost. On the 2.2, it seems to be a
latent bug only.

The lua 5.4 support was added. In addition, lua actions are now aborted if they 
explicitly yield, returning act.YIELD, on a final evaluation. It is only 
relevant when used in a tcp-request or tcp-response content ruleset.

Baruch Siach fixed HAProxy build with static only toolchains, such as uClibc.

And at last, the QUERY_STRING FCGI parameter is no longer url-decoded, as 
specified in the CGI/1.1 specification.

The remaining patches are minor bug-fixes and adjustments here and there as
