first pass through CHANGELOGS to extract 4_1_release_notes. [ci skip]
Extract **notable changes**, **deprecations** and **removals** from each CHANGELOG. I tried to reference the commits and pull requests for new features and deprecations. In the process I also made some minor changes to the CHANGELOGS. The 4_1_release_notes guide is declared WIP.

### Deprecations
|
||||
|
||||
* Deprecate `quoted_locking_column` method, which isn't used anywhere.
|
||||
|
||||
* Deprecate the delegation of Array bang methods for associations.
|
||||
To use them, instead first call `#to_a` on the association to access the
|
||||
array to be acted
|
||||
on. ([Pull Request](https://github.com/rails/rails/pull/12129))
|
||||
|
||||
* Deprecate `ConnectionAdapters::SchemaStatements#distinct`,
|
||||
as it is no longer used by internals. ([Pull Request](https://github.com/rails/rails/pull/10556))
|
||||
|
||||
### Notable changes
|
||||
|
||||
* Added `ActiveRecord::Base.to_param` for convenient "pretty" URLs derived from
|
||||
a model's attribute or
|
||||
method. ([Pull Request](https://github.com/rails/rails/pull/12891))
|
||||
|
||||
* Added `ActiveRecord::Base.no_touching`, which allows ignoring touch on
|
||||
models. ([Pull Request](https://github.com/rails/rails/pull/12772))
|
||||
|
||||
* Unify boolean type casting for `MysqlAdapter` and `Mysql2Adapter`.
|
||||
`type_cast` will return `1` for `true` and `0` for `false`. ([Pull Request](https://github.com/rails/rails/pull/12425))
|
||||
|
||||
* `.unscope` now removes conditions specified in
|
||||
`default_scope`. ([Commit](https://github.com/rails/rails/commit/94924dc32baf78f13e289172534c2e71c9c8cade))
|
||||
|
||||
* Added `ActiveRecord::QueryMethods#rewhere` which will overwrite an existing,
|
||||
named where condition. ([Commit](https://github.com/rails/rails/commit/f950b2699f97749ef706c6939a84dfc85f0b05f2))
|
||||
|
||||
* Extend `ActiveRecord::Base#cache_key` to take an optional list of timestamp
|
||||
attributes of which the highest will be used. ([Commit](https://github.com/rails/rails/commit/e94e97ca796c0759d8fcb8f946a3bbc60252d329))
|
||||
|
||||
* Added `ActiveRecord::Base#enum` for declaring enum attributes where the values
|
||||
map to integers in the database, but can be queried by
|
||||
name. ([Commit](https://github.com/rails/rails/commit/db41eb8a6ea88b854bf5cd11070ea4245e1639c5))
|
||||
|
||||
* Type cast json values on write, so that the value is consistent with reading
|
||||
from the database. ([Pull Request](https://github.com/rails/rails/pull/12643))
|
||||
|
||||
* Type cast hstore values on write, so that the value is consistent
|
||||
with reading from the database. ([Commit](https://github.com/rails/rails/commit/5ac2341fab689344991b2a4817bd2bc8b3edac9d))
|
||||
|
||||
* Make `next_migration_number` accessible for third party
|
||||
generators. ([Pull Request](https://github.com/rails/rails/pull/12407))
|
||||
|
||||
* Calling `update_attributes` will now throw an `ArgumentError` whenever it
|
||||
gets a `nil` argument. More specifically, it will throw an error if the
|
||||
argument that it gets passed does not respond to to
|
||||
`stringify_keys`. ([Pull Request](https://github.com/rails/rails/pull/9860))
|
||||
|
||||
* `CollectionAssociation#first`/`#last` (e.g. `has_many`) use a `LIMIT`ed
|
||||
query to fetch results rather than loading the entire
|
||||
collection. ([Pull Request](https://github.com/rails/rails/pull/12137))
|
||||
|
||||
* `inspect` on Active Record model classes does not initiate a new
|
||||
connection. This means that calling `inspect`, when the database is missing,
|
||||
will no longer raise an exception. ([Pull Request](https://github.com/rails/rails/pull/11014))
|
||||
|
||||
* Remove column restrictions for `count`, let the database raise if the SQL is
|
||||
invalid. ([Pull Request](https://github.com/rails/rails/pull/10710))
|
||||
|
||||
* Rails now automatically detects inverse associations. If you do not set the
|
||||
`:inverse_of` option on the association, then Active Record will guess the
|
||||
inverse association based on heuristics. ([Pull Request](https://github.com/rails/rails/pull/10886))
|
||||
|
||||
* Handle aliased attributes in ActiveRecord::Relation. When using symbol keys,
|
||||
ActiveRecord will now translate aliased attribute names to the actual column
|
||||
name used in the database. ([Pull Request](https://github.com/rails/rails/pull/7839))
