That won't be true for Action Pack and Action Mailer.

Bundle capybara 2.14.1 that includes fix for Ruby warnings

Ref: https://github.com/teamcapybara/capybara/pull/1868

Remove unreachable code

`Time.find_zone!` raise `ArgumentError` if invalid value is specified.
https://github.com/rails/rails/blob/379a0b42daf0d8e14130db7fd886d05d8d88e3f2/activesupport/lib/active_support/core_ext/time/zones.rb#L97..L99

Therefore, the return value never becomes nil.

form_with requires people to pass an id manually, so users can just
prefix their namespace right there.

Forgot all about https://github.com/rails/rails/pull/28844/files#r113780934

Rails.cache.write_multi foo: 'bar', baz: 'qux'

Plus faster `fetch_multi` with stores that implement `write_multi_entries`.
Keys that aren't found may be written to the cache store in one shot
instead of separate writes.

The default implementation simply calls `write_entry` for each entry.
Stores may override if they're capable of one-shot bulk writes, like
Redis `MSET`.

PostgreSQL 10 converts unknown type to text type

Commit 1a5d9399 removed the "Profiling Rails Applications" guide
but the YAML entry for this guide wasn't.

[ci skip]

Remove redundant `assert_nothing_raised` before another assertions

- Rename test cases from  `unknown` to `unrecognized` since unknown OID
is one of possible unrecognized types by Rails

- Use "select 'pg_catalog.pg_class'::regclass" whose OID is 2205, which
will not be converted to recognized type in PostgreSQL 10.

activerecord_unittest=# select oid, typname from pg_type where oid in (2205, 2277);
 oid  | typname
------+----------
 2205 | regclass
 2277 | anyarray
(2 rows)

Addresses #28868

Fix `test_pluck_without_column_names` when using Oracle

Remove html tag making markdown misrender [ci skip]

These `assert_nothing_raised` are covered by following assertions.

Testing `ReservedWordTest` for all adapters

Other examples were removed in 53ff5fc6

[ci skip]

`ReservedWordTest` expects that any identifiers are quoted properly.
It should be tested for all adapters.

Remove assert_nothing_raised, as test is already testing the required concerns

load_schema! is overridden by attribute modules, so we need to wait
until it has returned.

Introduce mattr_accessor default option

Don't create extra assignment, just return

Fix typo on error message when route definition is ambiguous.

Fix formatting of `direct` and `resolve` doc [ci skip]
