5.21.0

Features

• Experimental support for multi-threaded profiling using Vernier (#2372)

  You can have much better profiles if you're using multi-threaded servers like Puma now by leveraging Vernier.
  To use it, first add vernier to your Gemfile and make sure it is loaded before sentry-ruby.

  # Gemfile
  
  gem 'vernier'
  gem 'sentry-ruby'

  Then, set a profiles_sample_rate and the new profiler_class configuration in your sentry initializer to use the new profiler.

  # config/initializers/sentry.rb
  
  Sentry.init do |config|
    # ...
    config.profiles_sample_rate = 1.0
    config.profiler_class = Sentry::Vernier::Profiler
  end
