UNRELEASED

0.11.0

WARNING: THIS IS A BREAKING CHANGE RELEASE

This change should not impact most of the users as starting from 0.10.0 it is not required (and not recommended) to manually set the transport. DDtrace\Transport\Http no longer accepts a logger as the second argument as it uses the globally registered logger. If you are using the Http class, just remove the second argument from the constructor invocation.

Added

  • Support for guzzle 6 #254
  • Configurable Sampler #260
  • Debug mode for logging #261
  • Basic tracing for unsupported and custom frameworks #264
  • Support for symfony 3.3 #266 and #243
  • Build php 5.4 extension locally #267

Fixed

  • Composer PHP compatibility declaration #247
  • Release notes for PECL and fix type-os in CHANGELOG #248
  • Add missing files to PECL releases #252
  • PHP 5.4 installation and build #255
  • Trigger of autoloader un-tracing did not respect object #256
  • docker-compose based packages verification #257
  • Incorrect tar command in one-liner example from getting_started.md #258 - thanks @danielkay
  • Auto-instrumentation in Symfony 3.4 and PHP 5.6 #262
  • Type-o in command to install .deb packages #263

0.10.0

WARNING: THIS IS A BREAKING CHANGE RELEASE

Refer to the Migration Guide for a detailed description.

At an high level here are the breaking changes we introduced:

  • We removed OpenTracing as a required dependency. We still support OpenTracing, so you can do OpenTracing\GlobalTracer::get() in your code and still retrieve a OpenTracing compliant tracer, but OpenTracing dependency is now optional.
  • We introduced auto-instrumentation and 1-step installation in place of manual registration of providers/bundles. Before, in order to see traces, you had to install our extension, add two dependencies to the composer file and add a provider (Laravel) or a bundle (Symfony). Starting from now you will only have to install the extension. You still have freedom to manually instrument the code, but only for advanced usage.

  • Track integration loading to avoid re-loading unnecessary ones #211
  • Documenting release steps #223
  • Ability to run web framework tests in external web server #232
  • Support for auto-instrumentation #237
  • Support for Zend Framework 1 #238
  • Tracer::startRootSpan() to track the root Scope instance which can be accessed with Tracer::getRootScope() #241

Fixed
