2.0.1

• minor bugfixes (friendlier error reporting)

2-0

2.0

• incompatible change: erlperf requires runner arity to be defined explicitly. Code example: erlperf:run(#{runner => {timer, sleep, []}, init_runner => "1."}), with erlperf making a guess that init_runner is defined, therefore its return value can be passed as the argument to timer:sleep/1. This behaviour was confusing and is no longer supported.
• incompatible change: crashed runner causes entire job to stop (error contains the reason and stack trace)
• incompatible change: removed fprof/profiling support in favour of JIT + perf
• erlperf application is no longer required to be started for one-off benchmark runs
