Does anyone know how long new versions of Python take to get into Homebrew? Will current Python 3.6 installations on Homebrew autoupdate to Python 3.7 when brew update/brew upgrade is run and the new version is packaged?

Usually, it should be within few days.

I don't see any pull requests yet.

3.5->3.6 python was updated in the same package, so I guess python 3.7 will replace python 3.6 too. You will get it after you run brew upgrade.

i highly recommend pyenv.

`brew install pyenv; pyenv install 3.7`

Did you mean pyenv? pipenv is a package manager. You can specify in pipenv which version of Python your project needs, but to utilize it requires that that the version is already installed on your system.

You're welcome to create a PR. Homebrew's users are the primary contributors of package updates.

Notable parts of this release (IMO):

* Data classes (https://docs.python.org/3.7/library/dataclasses.html)

* New breakpoint() builtin (https://docs.python.org/3.7/library/functions.html#breakpoin...)

* Dictionaries preserve insertion order. (Implemented in 3.6, but now is part of the official spec.)

Data classes seem pretty neat. I haven't used attrs yet. And I rarely extend namedtuples, but it's nice to have a mechanism to do that built in.

breakpoint() is certainly more memorable than the current incantation.

Data classes are awesome! No more boilerplate __init__(self) methods needed.

Another notable part of this release is type annotations:
