• Changed doNotOptimizeAway to what google benchmark is doing. The old code did not work on some machines.
• fix #37: display correct "total" value
• minor Documentation updates

New major release! Direct download: nanobench.h

• API has been revised to be simpler and more intuitive. This is unfortunately not downward compatible, but the changes should be easy to fix. Most importantly, use now ankerl::nanobench::Bench instead of ankerl::nanobench::Config.
• Clock is now always the fastest available steady clock.
• Lots, and lots of documentation updates! See https://nanobench.ankerl.com. The documentation is now generated with the examples in the code, thus it will stay up to date much easier.
• Faster Rng
• Faster compile time, thanks to analysis with ClangBuildAnalyzer
• Improved mustache templates for JSON, CSV, and HTML templates
• Lots new templating features, with ability to calculate stuff
• Ability to specify exactly the number of iterations you want
• Lots of small & larger bugfixes

• Added asymptotic complexity calculation feature
• fixed division by zero
• improved doNotOptimizeAway handling
• better overhead estimation for more accurate instructions/op
• fixed when to show headers when Config isn't reused

• Lots of stabilizing of performance counters
• Improved markdown output
• better default configuration for epochs, runtime
• Better warnings & recommendations
• CSV fixes

This is an alpha release with Linux' Performance Counters support.

Where do I begin? Practically everything has changed

• Now with mustache template support
• better output
• g++4.8 support
• Compiles without warning for very strict compile settings
