What's Changed

• Make client smarter about Spring server state by @Korri in #756

Full Changelog: v4.6.0...v4.7.0

• Add Spring.dangerously_allow_disabling_reloading opt-in to skip the :ensure_reloading_is_enabled initializer check, so projects that want to run with config.cache_classes = true / config.enable_reloading = false can.
  The default behavior (refuse to boot) is unchanged, as using this option requires a Rails application that uses
  lazy-loader for everything (most importantly, routes & i18n translations).

What's Changed

• Add Spring.allow_reloading_disabled opt-in by @Korri in #755

Full Changelog: v4.5.0...v4.6.0

• Skip spring without error if spring is not in installed bundler groups.

• Adds a Spring.after_environment_load hook that runs immediately after the Rails application environment is
  loaded in the Spring server process, but before GC.compact/Process.warmup and before the server enters its
  wait loop. This hook enables applications to preload expensive test infrastructure (e.g. test helpers, fixture
  caches, datastore connections) into the Spring server so that forked test workers inherit that work via
  copy-on-write instead of paying it on every invocation.

• Fixed crashes when a client disconnects mid-handshake (e.g. on connect timeout). Previously, Errno::EPIPE
  raised in Spring::Server#serve or Spring::Application#serve would propagate up through the accept loop and
  kill the process, leaving a stale socket that broke every subsequent client. Both crash sites are now rescued,
  including writes that happen inside the rescue Exception handler in Application#serve while reporting an earlier failure to the gone client.

• Eagerly autoload framework base classes (ActionMailer::Base, ActionController::Base,
  ActionController::API) at the end of preload so their ActiveSupport.on_load hooks fire in the parent
  process. Without this, the reloader probe in #serve materializes Rails internals (notably Action View's
  CacheExpiry::ViewReloader) in a half-initialized state and triggers an expensive FileUpdateChecker rebuild
  on every prepend_view_path inside each fork. See rails/rails#51308 for the lazy-init contract this aligns
  with.
