#1539093 (Bug #92168) ** *** The new performance improvements for TCP over long latency connections could cause write/write deadlocks in proxies and brokers. To mitigate this, the default behavior has been changed to disabled. It can be re-enabled by setting 'net.autotune' to 1. Once enabled, it will work for any server configuration that does not have a proxy or a broker in the mix.
#1542613 (Bug #92377) ** Empty repos in graph depot could cause reference erors to be shown when running commands like 'p4 dirs' against unrelated paths. This has been fixed.
