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.
