- [API Change] lsquic_engine_connect() returns pointer to the connection object. - [API Change] Add lsquic_conn_get_engine() to get engine object from connection object. - [API Change] Add lsquic_conn_status() to query connection status. - [API Change] Add add lsquic_conn_set_ctx(). - [API Change] Add new timestamp format, e.g. 2017-03-21 13:43:46.671345 - [OPTIMIZATION] Process handshake STREAM frames as soon as packet arrives. - [OPTIMIZATION] Do not compile expensive send controller sanity check by default. - [OPTIMIZATION] Add fast path to gquic_be_gen_reg_pkt_header. - [OPTIMIZATION] Only make squeeze function call if necessary. - [OPTIMIZATION] Speed up Q039 ACK frame parsing. - [OPTIMIZATION] Fit most used elements of packet_out into first 64 bytes. - [OPTIMIZATION] Keep track of scheduled bytes instead of calculating. - [OPTIMIZATION] Prefetch next unacked packet when processing ACK. - [OPTIMIZATION] Leverage fact that ACK ranges and unacked list are. ordered. - [OPTIMIZATION] Reduce function pointer use for STREAM frame generation - Fix: reset incoming streams that arrive after we send GOAWAY. - Fix: delay client on_new_conn() call until connection is fully set up. - Fixes to buffered packets logic: splitting, STREAM frame elision. - Fix: do not dispatch on_write callback if no packets are available. - Fix WINDOW_UPDATE send and resend logic. - Fix STREAM frame extension code. - Fix: Drop unflushed data when stream is reset. - Switch to tracking CWND using bytes rather than packets. - Fix TCP friendly adjustment in cubic. - Fix: do not generate invalid STOP_WAITING frames during high packet loss. - Pacer fixes.
