09:53 AM Ruby Feature #21795: Methods for retrieving ASTs

Regarding the warning, I don't particularly like that. It's unactionable, I'm not going to downgrade prism to resolve it. The current latest prism is 1.9.0 from january and no released ruby has this as a default gem. I must also be aware... Earlopain (Earlopain _)

09:39 AM Ruby Feature #22205: Deprecate ruby2_keywords

ruby2_keywords still sees quite a bit of usage in the ecosystem.

more specific too. Earlopain (Earlopain _)

12:29 PM Ruby Revision 7ac76f6b (git): [ruby/prism] Rename some keyword locations for consistency

Prism is generally good about their naming but these had some inconsistencies compared to others:
* `InNode` was missing the `keyword` in the name
* `MatchPredicateNode` `in` was named `operator` instead
* `UnlessNode`/`UntilNode`/`When... Earlopain (Earlopain _)

06:42 PM Ruby Feature #5781 (Closed): Query attributes (attribute methods ending in `?` mark)

Sadly https://bugs.ruby-lang.org/issues/21555#note-10
> I still ask you to define def valid? = @valid manually. It is not much worse than attr_reader :valid?. Earlopain (Earlopain _)
