= Improvements
* The
r.is optimization added in 3.46.0 has been extended to optimize
all single argument calls. This results in the following speedups
based on argument type:
* Hash/Class matching: 20%
* Symbol matching: 25%
* Array matching: 35%
* Proc matching: 50%
* false/nil matching: 65%
* Roda now uses defined?(yield) instead of block_given? internally
for better performance on CRuby. defined?(yield) is faster as it is
built into the VM, while block_given? is a regular method and has
the overhead of calling a regular method. Note that defined?(yield)
is not implemented correctly on JRuby before 9.0.0.0, so this
release of Roda drops support for JRuby versions before 9.0.0.0.
