Bump tailwindcss-rails from 2.7.9 to 4.6.0

[dependabot]

Bumps tailwindcss-rails from 2.7.9 to 4.6.0.

Release notes

Sourced from tailwindcss-rails's releases.

v4.6.0 / 2026-06-17

Fixed

• tailwindcss:watch now forwards stop signals (SIGINT/SIGTERM) to the spawned tailwindcss process, instead of letting it be orphaned. This happens when a process manager signals the watch task directly rather than the whole process group — most commonly Procfile-based managers like foreman in development. @​jordan-brough

v4.5.0 / 2026-06-15

Improved

• New silent flag on tailwindcss:build and tailwindcss:watch tasks to suppress non-error output from the tailwindcss CLI (e.g., bin/rails tailwindcss:watch[silent]). Requires Tailwind CSS v4.3.1. #618 @​jordan-brough

New Contributors

• @​jordan-brough made their first contribution in rails/tailwindcss-rails#618

Full Changelog: rails/tailwindcss-rails@v4.4.0...v4.5.0

v4.4.0 / 2025-10-27

Changed

• Removed the "poll" option on the watch command, since Tailwind v4 dropped support for this option (and it has been a no-op in this gem since.) #580 @​flavorjones

Improved

• Support Rails 8.1 scaffolding which disables system tests by default. #585 @​flavorjones
• Puma plugin now has experimental support for Rails engines. #567 @​bopm
• Puma plugin uses Puma 7's after_stopped callback, quashing a deprecation warning. #578 @​rono23
