0.17.0 (2017-12-17)

• Changed method/class names produced by the callgrind printer to be more kcachegrind friendly (thx to Nelson Gauthier and Ben Hughes, see ruby-prof/ruby-prof#200).
• Recursive instances of a method call are now dtected during profiling (thx to Nelson Gauthier and Ben Hughes, see ruby-prof/ruby-prof#201).
• Methods can now be ignored during a profiling run instead of eliminating them after a profile run, which has been deprecated (thx to Nelson Gauthier and Ben Hughes, see ruby-prof/ruby-prof#202).
• Use RUBY_PROF_EDITOR_URI=emacs to open source code links in the one true editor. (thx Alexander Egorov, see ruby-prof/ruby-prof#183 and https://github.com/typester/emacs-handler).
• Fixed that calling profile.stop would stop profiling all active profiling runs.
• Fixed that remembering parent call frame pointer before stack reallocation could cause a segfault.

0.16.1 (2016-08-24)

0.16.0 (2016-08-24)

• ruby-prof can now be installed if ruby has been compiled with --disable-gems or RUBYOPT includes --disable-gems (thx to Arthur Nogueira Neves)
• Profile.new now accepts and prefers an options hash:
  • measure_mode: one of the RubyProf measure mode constants
  • exclude_threads: an array of threads to ignore when collecting profile data
  • include_threads: an array of threads to include when collecting profile data
  • merge_fibers: whether or not to merge the profile data for all fibers under their creating thread
