If casted value is nil, generated SQL should be `IS NULL`. But currently it is generated as `= NULL`. To prevent this behavior, avoid making bind param if casted value is nil. Fixes #28945.

|
* Add `ActiveRecord::Base#cache_version` to support recyclable cache keys via the new versioned entries
|
|
in `ActiveSupport::Cache`. This also means that `ActiveRecord::Base#cache_key` will now return a stable key
|
|
that does not include a timestamp any more.
|
|
|
|
NOTE: This feature is turned off by default, and `#cache_key` will still return cache keys with timestamps
|
|
until you set `ActiveRecord::Base.cache_versioning = true`. That's the setting for all new apps on Rails 5.2+

MySQL 8.0.1 and higher supports descending indexes: `DESC` in an index definition is no longer ignored.

Previously this method always returned an empty array.
