RAILS UNLOCKS RACTOR THREADING WITH SHAREABLE LOGGER AND PROXY LOGGER MERGES

By RepoJournal · Filed · About Rails

Rails shipped three major concurrency features that let you safely pass loggers across Ractor boundaries, a critical step toward multi-threaded Rails applications.

The most significant work landed in rails/rails: a new ActiveSupport::ShareableLogger [1] that wraps TaggedLogging and can be safely shared across Ractors, plus an ActiveSupport::ProxyLogger [2] that lets you route library logs to your app logger with independent severity levels. Both solve the hard problem of thread-safe logging in Ractor-enabled code. Template handler registries also went Ractor-shareable [3], removing a critical blocker for rendering views in background threads. On the ops side, rails/spring tightened CI by pushing Dependabot automation for GitHub Actions [4], and rails/devcontainer picked up Ruby 3.4.10 [5]. Rails World 2026 now has Arely Rivera confirmed as co-presenter [6], and the website updated the Basecamp logo [7].
