@ -114,6 +114,7 @@ The following features are new (or have been significantly updated) since versio
"ip.addr != 1.1.1.1" will work as expected (the result is the same as typing "ip.src != 1.1.1.1 and ip.dst != 1.1.1.1"). This avoids the
contradiction (a == b and a != b) being true.
** Use the syntax "a ~= b" or "a any_ne b" to recover the previous (inconsistent with ==) logic for not equal.
** Adds support for the syntax "a not in b" as a synonym for "not a in b".
* Corrected calculation of mean jitter in RTP Stream Analysis dialog and IAX2 Stram Analysis dialog
