3.0 changelog added!
Documentation linking switched to docs.ruby-lang.org for good. Unfortunately, alternative sites are glitching with Ruby’s everchanging docs formatting.

2.7 changelog added!
In 2.7 changelog, links to docs sometimes switched to “official” docs.ruby-lang.org website. Most of the time, we are linking to ruby-doc.org, which, while being unofficial, has two advantages: a) it looks a bit nicer and b) it doesn’t mix what is in core and what came from standard libraries. Unfortunately, as of release date of 2.7, ruby-doc.org’s rendering is unable to properly handle new core methods implemented in .rb files (compare GC docs on official site, and on ruby-doc.org) ruby-doc.org was fixed!
Atom feed added to the site, allowing to put it in your favorite aggregator (yes, I am aware it is almost 2020 and nobody does this anymore).

2.5 and 2.6 updated significantly with missing details/recent updates and mentions of upcoming (in 2.7) changes;

More metainformation about each version added to its page (initial release date, current status, etc.).
