0.1.5

Release improvements

• [rails] the sql.query meta is sent only once in the ActiveSupport instrumentation
• [rails] the sql.query meta is properly obfuscated. This process takes place in the trace-agent so that our APM backend will receive the SQL query without parameters
• add experimental support for JRuby 9k. Actually we're still targeting the compatibility mode >=2.1.0
• [rails] cache activity is monitored under the rails-cache service (it's a default name). This means that you can monitor cache interactions even outside a user request. The service name can be changed using the default_cache_service setting.

Improvements

Bugfixes

• The database service now is recognized as a "Database service"
• Rails users can change the database service name updating the default_database_service in the Rails.configuration.datadog_trace. If the value is not set, it defaults to the adapter_name

Other
