• Fix JSONGemCoderEncoder to correctly serialize custom object hash keys.

  When hash keys are custom objects whose as_json returns a Hash,
  the encoder now calls to_s on the original key object instead of
  on the as_json result.

  Before:
  hash = {CustomKey.new(123) => "value"}
  hash.to_json # => {"{:id=>123}":"value"}

  After:
  hash.to_json # => {"custom_123":"value"}

• Fix inflections to better handle overlapping acronyms.

  ActiveSupport::Inflector.inflections(:en) do |inflect|
    inflect.acronym "USD"
    inflect.acronym "USDC"
  end
  
  "USDC".underscore # => "usdc"

• Silence Dalli 4.0+ warning when using ActiveSupport::Cache::MemCacheStore.

Active Model

• Fix Ruby 4.0 delegator warning when calling inspect on attributes.

  Hammad Khan

• Fix NoMethodError when deserialising Type::Integer objects marshalled under Rails 8.0.

  The performance optimisation that replaced @range with @max/@min
  broke Marshal compatibility. Objects serialised under 8.0 (with @range)
  and deserialised under 8.1 (expecting @max/@min) would crash with
  undefined method '<=' for nil because Marshal.load restores instance
  variables without calling initialize.

Active Record

• Fix insert_all and upsert_all log message when called on anonymous classes.

  Gabriel Sobrinho

• Respect ActiveRecord::SchemaDumper.ignore_tables when dumping SQLite virtual tables.

  Hans Schnedlitz

• Restore previous instrumenter after execute_or_skip

  FutureResult#execute_or_skip replaces the thread's instrumenter with an
  EventBuffer to collect events published during async query execution.
  If the global async executor is saturated and the caller_runs fallback
  executes the task on the calling thread, we need to make sure the previous
  instrumenter is restored or the stale EventBuffer would stay in place and
  permanently swallow all subsequent sql.active_record notifications on
  that thread.

  Rosa Gutierrez

• Bump the minimum PostgreSQL version to 9.5, due to usage of array_position function.

  Ivan Kuchin

• Fix Ruby 4.0 delegator warning when calling inspect on ActiveRecord::Type::Serialized.

  Hammad Khan

• Fix support for table names containing hyphens.

  Evgeniy Demin

• Fix column deduplication for SQLite3 and PostgreSQL virtual (generated) columns.

  Column#== and Column#hash now account for virtual? so that the
  Deduplicable registry does not treat a generated column and a regular
  column with the same name and type as identical. Previously, if a
  generated column was registered first, a regular column on a different
  table could be deduplicated to the generated instance, silently
  excluding it from INSERT/UPDATE statements.

  Jay Huber

• Fix PostgreSQL schema dumping to handle schema-qualified table names in foreign_key references that span different schemas.

  # before
  add_foreign_key "hst.event_log_attributes", "hst.event_logs" # emits correctly because they're in the same schema (hst)
  add_foreign_key "hst.event_log_attributes", "hst.usr.user_profiles", column: "created_by_id" # emits hst.user.* when user.* is expected
  
  # after
  add_foreign_key "hst.event_log_attributes", "hst.event_logs"
  add_foreign_key "hst.event_log_attributes", "usr.user_profiles", column: "created_by_id"
