The feature became stable in 2.1, but still has questionable mindshare, so the further enhancements to it are covered in “deeper topics” section. It is meant to be a hygienic replacement for contextual extending of modules and classes. 2.0 Refinements are introduced as experimental feature.The latest blog post dedicated to the reference creation also juxtaposes the evolution of the language with my personal history and history of my country.□□ □□ General changes Please care to read two of my appeals to Ruby community before proceeding: first, second. I am finishing it after my daily volunteer work (delivering food through my district), why my homecity Kharkiv is still constantly bombed. □□ □□ This work was started in mid-February, before the start of aggressive full-scale war Russia leads against Ukraine. Nevertheless, a new method in one of the core classes frequently changes the way code could be written, not just adds some small convenience. The author of this list is focused on the changes of the language as a system of thinking and its syntax/semantics more than on a particular implementation.Īs Ruby is highly object-oriented language, most of the changes can be associated with some of its core classes. The choice of important features, their grouping, and depth of comment provided are informal and somewhat subjective. The detailed changelog currently covers versions since 2.4, and the brief changelog links to more detailed explanations for those versions (links are under version numbers at the beginning of the list items). It is part of a bigger Ruby Changes effort, which provides a detailed explanations and justifications on what happens to the language, version by version. It is intended as a “bird eye view” that might be of interest for Ruby novices and experts alike, as well as for curious users of other technologies. A very brief list of new significant features that emerged in Ruby programming language since version 2.0 (2013).
