RAILS STRIPS REDUNDANT SYMBOL CACHING, BOOTSNAP FIXES YJIT CACHE MISSES

Rails eliminated a now-unnecessary symbol-to-string cache layer by leveraging Ruby 3.0's Symbol#name, while bootsnap's latest release stops discarding its entire compile cache when YJIT is toggled.

The Rails team removed `symbol_column_to_string`, a memoization helper added years ago to avoid allocations during `respond_to?` checks on column names [1]. The optimization is obsolete: `columns_hash` already provides O(1) lookups on an interned string hash, and Symbol#name in Ruby 3.0+ yields that string without allocation. This is a clean simplification that cuts unused code without trading away performance [2]. Separately, Rails is eager-loading strict-locals templates at boot time, making them shareable across requests and Ractors [3]. Both changes land on top of ongoing cleanup: unused Active Record internals were pruned [4], and reflection key handling is being unified under a single Enumerable API [5]. Over in GlobalID, a fix ensures `.fetch` works on models with `find` but no `where` method, restoring the documented contract [6]. Bootsnap 1.25.0 arrives with two wins: smarter YAML caching for temporal types and a critical fix for YJIT users [7]. Previously, toggling YJIT via `--yjit` or environment variable invalidated the entire compile cache because the JIT marker changes RUBY_DESCRIPTION, even though serialized bytecode doesn't change. That's fixed now, keeping the cache hot across development sessions.

Action items

→ Upgrade bootsnap to 1.25.0 to stop losing compile cache on YJIT toggle rails/bootsnap [plan]
→ Review Rails changes to symbol column handling in your app if you override respond_to? rails/rails [monitor]
→ If using GlobalID with non-AR models, update and test .fetch behavior rails/globalid [plan]
