Business Class 2.1 released

Business Class is a Ruby on Rails template, now for Rails 8.1 and with faster test suite.

I’ve been writing Ruby for many years, and one thing is constant:

if we don’t stay updated with changes in the ecosystem, warnings, deprecations and noisy failures take over our logs and slow us down. So I wrote a detailed breakdown of Bundler 4.0.0.beta1, what’s changing, what’s being removed, and why this version is an important step for a cleaner and more modern Ruby workflow.

The Embarrassing Ruby/Rails Subreddit Chronicles 2025-11-24
