The following changes were made in A-Shell build 1164 of 20 Oct 2009.

The protocol for passing the server's ATE license to the ATE client on A-Shell startup has been streamlined in the case where the server has a "system" ATE license (meaning that ATE is allowed on all client connections). The new protocol only has an effect when both the server and client are running 5.1.1164.0+, but does not interfere when either side is older. When in effect, the job is no longer forced to execute LICENS/ATESRV to issue the license, with eliminates a few handshaking steps, speeding up the login and possibly avoiding some problems with slow connections and type ahead during complicated startup sequences.

The timeout for the initial ATE handshake has been increased from 3 seconds to 8 seconds, in order to be more tolerant of connections with high latency or other intermittent pauses.
