If we use a real version, at best that'll be an onerous update required
for each release; at worst, it will encourage users to write new
migrations against an older version than they're using.
The other option would be to leave these bare, without any version
specifier. But as that's just a variant spelling of "4.2", it would seem
to raise the same concerns as above.
According to pr #22443 in the guides there's always a dollar sign before every command, so why is in the main README a `$` and in every submodule a `%`?
Just eye candy..
I think we are better off leaving `sudo` outside of the documented
way of installing gems (`activerecord`, `actionpack`, …).
We don’t want newbies to think that `sudo` is required or, even worse, than
they actually have to type `[sudo] gem install`.
In most scenarios, `sudo` is not needed to install gems, and people who do
need it, probably already know about it.
What do you think? 😁
This reverts commit 14fc8b34521f8354a17e50cd11fa3f809e423592.
Reason: we need to discuss a better path from this removal.

This feature adds a lot of complication to ActiveRecord for dubious
value. Let's talk about what it does currently:
class Customer < ActiveRecord::Base
composed_of :balance, :class_name => "Money", :mapping => %w(balance amount)
end
Instead, you can do something like this:
def balance
@balance ||= Money.new(value, currency)
end
def balance=(balance)
self[:value] = balance.value
self[:currency] = balance.currency
@balance = balance
end
Since that's fairly easy code to write, and doesn't need anything
extra from the framework, if you use composed_of today, you'll
have to add accessors/mutators like that.

- don't reference ancient gem versions
- don't link to old API doc subdomains
- point to GitHub instead of RubyForge
- point to Lighthouse account for support
