Rails 8.1

As of: 2026-01 (8.1.x patching through Sep 2026)

Headline features

• Active Job continuations — long-running jobs can pause and resume (checkpoint state), instead of hand-rolled offset/retry hacks for hours-long imports and batch processing.
• Structured event reporting — ActiveSupport notifications emit structured (JSON-shaped) events; observability integration without log-scrubbing regexes.
• Local CI — a framework-blessed way to run CI checks locally before pushing; same entrypoint as the pipeline.
• Markdown rendering in the framework — rendering MD safely (sanitized) without adding a gem stack.

Context

Rails 8 (2024) already made the default stack kamal+solid_* (SQLite-backed queue/cache/db) deployable to a bare VM without external services. 8.1 deepens the "batteries included, ops optional" story. Upgrades from 8.0 are notably smooth.
