- We now use pcap_create and pcap_activate for pcap interfaces if libpcap 1.0 or later is available. This doesn't seem to make much of a difference performance-wise, as pcap_open_live was updated to use these functions anyway. This means if mmapped packet capture is available, we would have used it via pcap_open_live anyway.
- Added a new function (trace_interrupt). Calling this function will set an internal variable which can be used to cause any blocking read_packet function to exit with an EOF. Useful for programs that are handling signals themselves and need a way to tell libtrace to stop. Prior to this, programs like tracestats would not exit on Ctrl-C if reading from a pcap interface which was not receiving any packets.
- Updated pcap interface format to respond to trace_interrupt.
- Optimising trace_apply_filter to minimise calls to trace_get_link_type and trace_get_packet_buffer.
- Removed unused extern variable "form" from libtrace_int.h
- Fixed bug with filters in the pcap interface format which would result in "invalid BPF program" error message when filter was definitely legit.
- Updated version number to 3.0.13

| 16 | libtrace was primarily designed for use with the real-time interface to the |
