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.

• Type-o in command to install .deb packages #263

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 an 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.

• 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
