Ruby 3.0
Fedora 34 provides Ruby 3.0, the latest version of the Ruby language. Notable features of Ruby 3.0, compared to previous versions:
-
The ability to run concurrently is updated with regards to Ruby 2.7, with
Fiber Scheduler
and the preliminary addition ofRactor
. -
Static typing:
RBS
provides a foundation for allowing programs written in Ruby to define types. Ruby remains a dynamically typed language by default, butRBS
acts as an additional (foundation) layer of a program to provide static type functionality and gain some of the benefits of a statically typed language. -
IRB
gains some performance advantages: it is quicker, and now one can measure the execution time using themeasure
command. -
Standard libraries are updated.
-
Pattern matching is now a stable feature.
