  🚀 This release adds "User Defined Measurements" to the library. This was a great contribution that comes with new example code and an updated README.md.

• v2.3.0 Changes

  July 02, 2018

  • 👍 CMake exports are improved (it is better integrated into CMake's ecosystem).
  • Console output is formatted as a Markdown table for easy copy/paste into reports.
  • Notifies the user when executing in Debug mode (because the results would not be valid measurements).
  • 📚 Minor documentation updates.
  • ⚡️ Reduced the overhead of "DoNotOptimizeAway".
  • ✅ Greatly improved Google Test integration.
  • 👌 Improved the random number generation.
  • ⚡️ Updates for GCC/Linux.
  • ✅ Not tested on Mac.

• v2.2.0 Changes

  March 11, 2018

  • 👌 Improved CMake integration.
  • Console table is now formatted as Markdown.
  • 🚚 CPU throttle controls have been removed.
  • Added an example of shared_ptr measurements which includes OpenScenGraph's ref_ptr.

• v2.1.1 Changes

  February 03, 2018

  ⚡️ Minor code updates and cleanup.

• v2.1.0 Changes

  October 05, 2017

  ⚡️ Updated for CPPCon 2017.

• v2.0.7 Changes

  May 28, 2017

  🚀 This release adds two new experiments from Bartek. (http://www.bfilipek.com/2017/04/packing-bools.html)
  📚 The documentation was updated.

• v2.0.6 Changes

  February 27, 2017

  📚 This release introduces exception catching and has a few minor updates to the documentation.

  • 📚 The documentation was updated.
  • Clang Format was applied to all source code files.
  • 👻 Exception handling was added. Enable via the command line "--catchExceptions" option.
  • Failure handling was added to archives.
    *Minor bugs in the statistics were resolved.

• v2.0.5 Changes

  March 28, 2016

  🚀 This release re-adds the code to automatically compute some reasonable iteration count and sample size.

  📚 The documentation was updated for this as well. In short, simply set your sample size to zero and Celero will attempt to do your job for you.

  BENCHMARK(DemoSimple, Complex1, 0, 0) { celero::DoNotOptimizeAway(static\_cast\<float\>(sin(fmod(UniformDistribution(RandomDevice), 3.14159265)))); }
  

  Will produce something like:

  -----------------------------------------------------------------------------------------------------------------------------------------------
       Group | Experiment | Prob. Space | Samples | Iterations | Baseline | us/Iteration | Iterations/sec |
  -----------------------------------------------------------------------------------------------------------------------------------------------
  DemoSimple | Complex1 | Null | 30 | 4194304 | 1.00535 | 0.20928 | 4778189.16 |
  

  👀 You can see that the specification of 0 samples and 0 iterations produced 30 samples and 4194304 iterations when it runs. This is based on making numerous measurements before actually running the experiment to determine reasonable values for these two numbers.
