Like for real this time. I checked.

 Fixed typos in ActiveRecord CHANGELOG [ci skip]

Add an option `end` to `find_in_batches`

The various databases don't actually need significantly different
handling for this behavior, and they can achieve it without knowing
about the type of the object.

The old implementation was returning a string, which will cause problems
such as breaking TZ aware attributes, and making it impossible for the
adapters to supply their logic for time objects.

Documentation Fix: Corrects explanation of what happens when dependent is not set

Fixes #18871

Document lazy lookup behavior for controllers [ci skip]

Significantly faster than `SimpleDelegator`.

Remove warning from ActionView::Helpers::Tags::Translator

An array type is a part of `sql_type`

By default the foreign key will remain set with the parent id after
destroy is fired.

The default of the global might change. It's better to reset it to
what it was than a hardcoded value.

Remove warning from generator named base test

Remove warning from Plugin Generator

This removes the following warning:

  railties/test/generators/named_base_test.rb:9: warning: method redefined; discarding old pluralize_table_names
  activesupport/lib/active_support/core_ext/class/attribute.rb:86: warning: previous definition of pluralize_table_names was here
  railties/test/generators/named_base_test.rb:9: warning: method redefined; discarding old pluralize_table_names=
  activesupport/lib/active_support/core_ext/class/attribute.rb:83: warning: previous definition of pluralize_table_names= was here

This removes the following warning:

    /GitHub/rails/actionview/lib/action_view/helpers/tags/translator.rb:19: warning: private attribute?

Explicitly ignored wildcard verbs from head_routes

This removes the following warning:

  rails/railties/lib/rails/generators/rails/plugin/plugin_generator.rb:321: warning: shadowing outer local variable - content

that complements the `start`parameter to specify where to stop batch processing

In match_head_routes, deleted the routes in which request.request_method was empty (matches all HTTP verbs) when responding to a HEAD request. This prevents catch-all routes (such as Racks) from intercepting the HEAD request.

Fixes #18698

Added by 101c19f5.

Fix rounding problem for PostgreSQL timestamp column

If timestamp column have the precision, it need to format according to
the precision of timestamp column.

Respect the database default charset for `schema_migrations` table.

Add `auto_increment?` instead of `extra == 'auto_increment'`

Remove unused line

Missing `@` [ci skip]

`sql_type` is reused in `lookup_cast_type`. If making it a part of
`sql_type` when handled array option first, it isn't necessary to do
again.

The charset of `version` column in `schema_migrations` table is depend
on the database default charset and collation rather than the encoding
of the connection.

This predicate is only used in `query_attribute`, and is relatively easy
to remove without adding a bunch of is a checks.

This predicate was only to figure out if it's safe to do case
insensitive comparison, which is only a problem on PG. Turns out, PG can
just tell us whether we are able to do it or not. If the query turns out
to be a problem, let's just replace that method with checking the SQL
type for `text` or `character`. I'd rather not burden the type objects
with adapter specific knowledge.

The *real* solution, is to deprecate this behavior entirely. The only
reason we need it is because the `:case_sensitive` option for
`validates_uniqueness_of` is documented as "this option is ignored for
non-strings". It makes no sense for us to do that. If the type can't be
compared in a case insensitive way, the user shouldn't tell us to do
case insensitive comparison.

The type code is actually quite accessible, and I'm planning to
encourage people to look at the files in the `type` folder to learn more
about how it works. This will help reduce the noise from code that is
less about type casting, and more about random AR nonsense.

It only existed to make sure the subclasses of `Delegator` were YAML
serializable. As of Ruby 2.2, these are YAML dumpable by default, as it
includes
