0.20.0

Added

• Force tracing or discarding trace via special Span tag (manual.keep and manual.drop) #409

Fixed

• Resource use by caching configuration values instead of processing data on every access #406

0.19.1

Fixed

• Tracing of functions called using DO_FCALL_BY_NAME opcode #404
• Curl headers not being correctly set #404

0.19.0

Changed

• Span and SpanContext main implementation uses public fields to share data to allow faster serialization and overall Span overhead #398
• DDTrace\Encoders\SpanEncoder::encode() now takes an instance of DDTrace\Data\Span instead of DDTrace\Contracts\Span #398
• DDTrace\Processing\TraceAnalyticsProcessor::process() now takes an instance of DDTrace\Data\Span instead of DDTrace\Contracts\Span #398
• Improve performance of setTag and setResource #398
• Load required PHP files in one go #387
• Load optional PHP files without filesystem check #387

0.18.0

NOTE: THIS IS A BREAKING CHANGE RELEASE

This change should not impact most users.

Added

• MessagePack serialization for traces sent to the Agent with a new function dd_trace_serialize_msgpack() #378

Changed

• Request init hook module blacklist now avoids miss matching partial matches #372
• Add 10MB cap to payloads sent to the Agent #388
• Added an getTracesAsArray() method to DDTrace/Contracts/Tracer which returns an array of spans (which are also encoded as an array.) To encode an instance of DDTrace\Contracts\Span as an array, use DDTrace/Encoders/SpanEncoder::encode($span) #378
• DDTrace/Transport::send() now takes an instance of DDTrace/Contracts/Tracer instead of an array #378
• DDTrace/Encoder::encodeTraces() now takes an instance of DDTrace/Contracts/Tracer instead of an array #378
• The default encoder is now DDTrace/Encoders/MessagePack. You can still use the JSON encoder by setting the environment variable DD_TRACE_ENCODER=json. It is generally not recommended to use the JSON encoder as parsing JSON payloads at the Agent level is more CPU & memory intensive.
