Really exciting to see Herb being adopted at GitHub! 🌿
Over the past months, the GitHub team has been running Herb across one of the largest Rails codebases out there where Herb helped uncover real issues missed by existing tooling while also providing invaluable feedback. 🙌
After weeks of work, Ruby’s master documentation now displays rbs signatures!
We will release this feature in RDoc 8.0 soon as well. So any projects using rbs (inline or .rbs files) can benefit from it too.
Check it on docs.ruby-lang.org/en/master

2.7.2 was the last version before I took over maintainership.
2.9.0 was the version I released at the end of the blog series.
If you haven't upgraded yet, Ruby 4.0's garbage collection is generally much faster than 3.4. This patch release fixes the one area there had previously been a notable regression (allocating/freeing Classes).

Zeitwerk 2.8 is out, with a new way to define namespaces.
Given
loader.nsfile = 'ns.rb'
self-contained components can define their namespace inside their folder:
my_component/ns.rb # MyComponent
my_component/widget.rb # MyComponent::Widget
More details in github.com/fxn/zeitwerk...
We had a speaker drop out of the Rust Berlin meetup next week (Friday, 29th, at JetBrains). Anyone wants to speak?
If you get in touch before Sunday, I will think about something to bring you from Japan as a gift.
