Rails patched a `in_order_of` crash when querying Common Table Expressions, while tailwindcss-rails 4.6.0 finally kills zombie watchers that plague foreman-based development.

The Rails team merged a fix [1] for `in_order_of` raising `NoMethodError` when column names can't be resolved in CTEs. The issue stems from `order_column` returning an `Arel::Nodes::SqlLiteral` that lacks type information, so the query builder tried to type-cast something that doesn't exist. The solution skips type casting for CTE columns where type info isn't available anyway [2]. This is a surgical fix for anyone using modern Rails query patterns with window functions and temporary result sets. Separately, Rails hardened the helper method system for Ractor safety [3], following the same dup-add-freeze-reassign pattern established in recent concurrency work. The framework also stripped unnecessary complexity from content string handling [4], removing a nil interpolation workaround now optimized away in Ruby 3.1. Over in the asset pipeline, tailwindcss-rails 4.6.0 [5] shipped with signal forwarding for the watch task [6], eliminating the orphaned `tailwindcss` CLI processes that plague foreman users. When foreman sends SIGTERM to the watch task, it now traps INT and TERM, forwards them to the spawned child, and waits for cleanup instead of abandoning zombie processes. This is the fix for anyone who's had to manually kill tailwindcss watchers mid-development.
