Improvements

• The gem is available in the rubygems.org repository
• Extended support to Ruby 2.4.0
• Extended support to Passenger 5.0+

  rendering are instrumented. See Sinatra documentation for more details.

  the built-in module is used. See HTTP documentation for more details.

Bugfixes

• Use alias_method in Redis instrumentation to prevent recursion when
  other libraries are patching the same class (#56)

Breaking changes

• Rails auto-instrumentation is disabled by default. You have to manually
  activate the Rails instrumentation in your initializer. See Rails documentation
  for more details (#55)

Migrate from 0.3.1 to 0.4.0

• The official rubygems.org repository should be used and new versions will not be available in the previous repository. To receive new updates, change your Gemfile as follows:

source 'https://rubygems.org'

# tracing gem
gem 'ddtrace', '0.4.0'

# ...other gems...

• If you're using the Rails integration, update your config/initializers/datadog-tracer.rb so that the
  auto_instrument and auto_instrument_redis are both enabled (or
  disabled according to your choice). You can find an example in the following
  code:

# config/initializers/datadog-tracer.rb

# this condition activates or deactivates the Rails auto instrumentation
# according to your environment; change it so that it reflects your
# application requirements
tracer_status = Rails.env.staging? || Rails.env.production?

Rails.configuration.datadog_trace = {
  auto_instrument: tracer_status,
  auto_instrument_redis: tracer_status,
  default_service: 'my-rails-app',
  # ...other configurations...
}
