- Mentioned clearly that for PostgreSQL < 9.4, you need to pass the
default option with "uuid_generate_v4()"
- Also updated PostgreSQL Active Record guide with this change.

The first release note entry mentioned #on_weekday?, but that was only
added by the second PR mentioned there. To simplify reading the notes
just merge the two, since they are related methods. [ci skip]
The hashes returned in some examples of the following sections had items in a different order than their receivers. That may mislead readers into believing those methods will not preserve element order.
Extensions to Hash/Working with Keys/transform_keys and transform_keys!
Extensions to Hash/Working with Keys/stringify_keys and stringify_keys!
Extensions to Hash/Working with Keys/symbolize_keys and symbolize_keys!
Extensions to Hash/Slicing
This replaces boilerplate in the “benchmark your code” section of the
contributors’ guide with an executable template. I also amended the text
to encourage best practices and codified it in the template.
For now this is only good for relatively self-contained changes that can
be inlined into a simple script. In the future, this can be expanded to
cover how to measure the difference between two commits.
The output looks like this:

ActionDispatch::ParamsParser class was removed in favor of
ActionDispatch::Http::Parameters so it is better to move the error
constant to the new class.
When the initial evented monitor feature was written, the latest version of listen
was the 3.0.x series. Since then the listen project has moved on to the 3.1.x series.
This patch allows the use of the new versions.
