Updates for March 22

[Mark McGranaghan]

Hi everyone,

We have a few updates from the past week:

== API Libraries
- stripe-java version 1.47.0 has been released. Changelog: https://github.com/stripe/stripe-java/blob/master/CHANGELOG
- stripe-php version 3.11.0 has been released. Changelog: https://github.com/stripe/stripe-php/blob/master/CHANGELOG.md
- stripe-ruby version 1.38.0 has been released. Changelog: https://github.com/stripe/stripe-ruby/blob/master/History.txt

Note that stripe-php 3.11.0 contains a bug fix for incorrect parameters being passed when an application fee is being refunded, so we highly recommend that users upgrade to it.
