* Leave two blank lines between sections/packages for readibility.
* Always indent bullet points with four spaces. This allows multi-paragraph
points to align properly (see #16103), and it is the same as the format we
already use in CHANGELOGs. Doing this consistently sets an easy precedent
for future contributors to follow.
* Always put the PR/commit link on its own line in the source. If the bullet
point spans multiple paragraphs, put it on its own paragraph at the end.
[Godfrey Chan & Juanito Fatas]
Reliant on https://github.com/rails/rails/pull/15747 but pulled to a
separate PR to reduce noise. `has_many :through` associations have the
undocumented behavior of automatically detecting counter caches.
However, the way in which it does so is inconsistent with counter caches
everywhere else, and doesn't actually work consistently.
As with normal `has_many` associations, the user should specify the
counter cache on the `belongs_to`, if they'd like it updated.
Point to future 4-2-stable branch for detailed changes. [ci skip]
