• Update concurrent-ruby dependency

• Add Debugger on_error configuration.
• Update Transmitter
  • Add dependency on current-ruby.
  • Add Transmitter#on_error method.
  • Update Transmitter documentation.
• Make use of Credentials#project_id
  • Use Credentials#project_id If a project_id is not provided, use the value on the Credentials object. This value was added in googleauth 0.7.0.

• Update documentation.

• Update documentation.

• Fix issue when disabling Stackdriver components with Rails.env.production.
• Add documentation for enabling gRPC logging.

• Delay starting the debugger agent until the first request to ensure it happens after workers are forked. Should prevent grpc from malfunctioning in this case.

• Use Google Cloud Shared Configuration.
• Fix for mutation detection using Ruby 2.5.
• Support disabling mutation detection in debugger evaluation.

• Update google-gax dependency to 1.0.

• Fix credentials verification bug in Railtie.

• Document Google::Auth::Credentials as credentials value.
• Add Debugger Agent Design Document.
• Updated google-gax (grpc, google-protobuf), googleauth dependencies.

• Improve Breakpoint tracer performance by not tracking C function calls in file tracing.
• Add a backoff behavior in the debuggee registration to reduce spamming requests when registrations fail.

• Print captured exception from asynchronous worker threads.

• Support single file Rack-based applications.
• Support none-Rack-based Ruby applications.

• Optimize breakpoint evaluation memory usage by adopting shared variable table.
• Update breakpoint to error state if the breakpoint is set at an invalid position or if condition evaluation fail with an error.
• Set errored variable evaluation to error state.
• Restrict the amount of time spent on evaluating breakpoints within each rack application request.
• Restrict total memory usage on collecting variables within each breakpoint evaluation. Prioritize memory allocation to user defined variables over local variables.

• stackdriver-core 1.2.0 release

• Update GAPIC configuration to exclude UNAVAILABLE errors from automatic retry.

• Introduce new Google::Cloud::Debugger.configure instrumentation configuration interface.

• Fixed Google::Cloud::Debugger::Railtie initialization on non-GCP environments to not interfere with Rails startup

• First release
