Ok, just wanted to post my experience with 1.4.0 rc.

Well, not really a drop in replacement - few things need to be updated in lwipopts.h, since I had an error with NO_SYS_NO_TIMERS (which is defaulted to 0, but should be 1). Other than that, they have split the tcp.h to tcp.h and tcp_impl.h, which both need to be included in your main.c file.

Other than that, it's running better - I don't know for anyone else, but my lwip 1.3.2 UDP implementation had major problems with IP addresses (IP layer did not forward them to the transport layer correctly - ie on callback it always forwarded its own IP instead of the IP from remote host (?!?) ). However, I did change a lot of things and this might have caused this behavior (but than again, 1.4.0 works perfectly with the same changes).

Who knows? Just wanted to update if someone has the same problems.
