General Changes
- Some changes have been made to the HostDB data structures. The defaults configurations that ships with ATS v6.x still works, but if you have made changes to either of these configurations, you might have to modify them. Specifically, you might have to either reduce the number of entries supported, or, increase the storage size.

New configuration options
- proxy.config.http.origin_max_connections_queue limits the number of requests to be queued when the
proxy.config.http.origin_max_connections
is reached. - Two new timeouts are available for WebSockets: proxy.config.websocket.no_activity_timeout and proxy.config.websocket.active_timeout.
- The congestion control algorithm used is now configurable for both incoming, and outbound connections, via proxy.config.net.tcp_congestion_control_in and proxy.config.net.tcp_congestion_control_out.
- In preparation for the new Lua metrics module in v7.0.0, you can enable this feature in v6.2.x with proxy.config.stats.enable_lua.
- An experimental implementation of H2 streams priorities can be enabled with proxy.config.http2.stream_priority_enabled.
- We now provide better control over various H2 (HTTP/2) features, including proxy.config.http2.min_concurrent_streams_in, proxy.config.http2.max_active_streams_in and proxy.config.http2.active_timeout_in.
