Hello, this is Wojtek reporting on last month additions to Rails codebase.
The last minor version of Ruby 2.7 before 3.0 release in the next year. Rails codebase is constantly updated to support Ruby 2.7 without any warnings.
Optimization and bug fix by avoiding existence checks in the storage service.
Handy addition to clean up common use case with constructing class names when creating content tags.
As a follow-up to conditional values in Tag Builder, to ease even more constructing class names on views.
From now on config_for will deeply merge shared configuration section with environment specific one.
