5.16.0

Features

• Add backpressure handling for transactions #2185

  The SDK can now dynamically downsample transactions to reduce backpressure in high
  throughput systems. It starts a new BackpressureMonitor thread to perform some health checks
  which decide to downsample (halved each time) in 10 second intervals till the system
  is healthy again.

  To enable this behavior, use:

  Sentry.init do |config|
    # ...
    config.traces_sample_rate = 1.0
    config.enable_backpressure_handling = true
  end

  If your system serves heavy load, please let us know how this feature works for you!
