0.47.0

Added

• Document support for httpx integration (#1396) (@HoneyryderChuck)
• Schemas to list of supported AWS services (#1415) (@tomgi)
• Branch test coverage report (#1343)

Changed

• BREAKING Separate Resolver configuration and resolution steps (#1319)

  ActiveRecord describes configuration now supports partial matching

  Partial matching of connection fields (adapter, username, host, port, database) is now allowed. Previously, only an exact match of connections fields would be considered matching. This should help greatly simplify database configuration matching, as you will only need to provide enough fields to correctly separate your distinct database connections.

  If you have a c.use active_record, describe: statement in your application that is currently not matching any connections, you might start seeing them match after this release.

  c.use active_record, describe: statements that are currently matching a connection will continue to match that same connection.

  You can refer to the expanded ActiveSupport documentation for details on how to use the new partial matchers and configuration code examples.

  Datadog::Contrib::Configuration::Resolver interface changed

  The interface for Datadog::Contrib::Configuration::Resolver has changed: custom configuration resolvers that inherit from Datadog::Contrib::Configuration::Resolver will need be changed to fulfill the new interface. See code documentation for Datadog::Contrib::Configuration::Resolver for specific API requirements.

0.45.0

This release includes a new way to automatically instrument all available gems in an application: require: 'ddtrace/auto_instrument' (#1260). There's no need to require 'ddtrace' or invoke Datadog.configure when using auto_instrument.

For Rails application, all that is needed is an additional require option in your Gemfile:

gem 'ddtrace', require: 'ddtrace/auto_instrument'

For any other application, invoke require 'ddtrace/auto_instrument' after all gems that you would like instrumented have been required.

All defaults and custom settings can still be configured in a Datadog.configure block as usual. Make sure to call Datadog.configure after require 'ddtrace/auto_instrument' when using both features together.

Let us know if you have any feedback on this new feature in our GitHub page.

There are no changes for applications not invoking require 'ddtrace/auto_instrument'.

Added

• Option to auto enable all instrumentations (#1260)
• httpclient support (#1311) (@agrobbin)

0.44.0

Added

• Ruby 3.0 support (#1281, #1296, #1298)
• Rails 6.1 support (#1295)
• Qless integration (#1237) (@sco11morgan)
• AWS Textract service to AWS integration (#1270) (@Sticksword)
• Ability to disable Redis argument capture (#1276) (@callumj)
• Upload coverage report to Codecov (#1289)

Changed

• Reduce Runtime Metrics frequency to every 10 seconds (#1269)
  We reduced the frequency from every 1 second to every 10 seconds. This greatly reduces the overhead of using Runtime Metrics: 10% (26MiB) memory usage reduction in a sample Rails 6 application) while not having measurable impact on the quality of data collected. It also aligns dd-trace-rb with other language tracers.
