------------------- - Path and route blacklists now work also for firehose traces
0.25.0
------------------- - Remove `zipkin.always_emit_zipkin_headers` config option. Rather than using set_property to add the trace_id to the request, we now do a simple assignment which is way faster and removes the need for that flag.
0.24.1
------------------- - Update tween to support py-zipkin 0.18+
0.24.0
------------------- - Add `zipkin.encoding` param to allow specifying the output span encoding.
0.23.0
------------------- - Add post_handler_hook to the tween.
0.22.0
------------------- - Set `zipkin.use_pattern_as_span_name` to use the pyramid route pattern as span_name rather than the raw url. - Requires py_zipkin >= 0.13.0.
