Fixed an issue where, after disabling and re-enabling the external syslog server, the TCP session was not resumed, which caused all logs that were forwarded to the syslog server to be dropped.

Fixed an issue where set and edit commands took longer than expected when adding address objects with a large number of dynamic groups due to the completion cache being enabled. With this fix, the completion cache is disabled by default.

Fixed an issue where TLS connections failed to establish in asymmetric routing environments if the firewall did not see server-to-client (s2c) packets of the TLS handshake.

To use this fix, run the following CLI command: debug dataplane set ssl-decrypt accumulate-client-hello asym-disable yes.
