When creating a new app with rails new myapp --database=mysql, I get an error when attempting to load the app:

Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

Manually specifying the version of mysql2 to be v0.3.20 works fine.

I didn't realize the AR adapter was using a squiggly require, so this will cause some confusion because Bundler doesn't know that it needs to hold back the mysql2 version.

@jeremy Thanks for updating the adapter - I left you a few comments on #21536

Temporarily constrain mysql2 gem to ~> 0.3.20

We would prefer to only constrain mysql2 to '~> 0.3',
but a rails bug (rails/rails#21544)
requires us to constrain to '~> 0.3.20' for now.

Just a suggestion, this issue would have been easier to diagnose if the exception message from Gem::LoadError was not swallowed up by the exception handler when the adapter specific code is required.

For Rails 3.2.xxx need use:
gem 'mysql2', '~> 0.3.20' ?

RoR 3.2.xxx no longer supported
And what about RoR 4.0, RoR 4.1 ?

Lock testing mysql2 version for rails4x unit tests
f1483ed 
This locks the mysql2 adapter to the same versioning scheme
as listed in the active record source for the deprecated
4.x branches 4.0.x and 4.1.x. This prevents otherwise
incorrect load errors when running the rails40 and rails41
suites. See also: rails/rails#21544

Hold back MySQL Gem version

There is an incompatibility with Rails 4.2 and MySQL 0.4.x as per
rails/rails#21544. Updating Rails should fix
this problem but for now this is the simplest fix.
