# Revision history for pushbullet-types
## 0.1.0.0 -- 2017-02-20
Define the following core types:
* `Push` -- messages used internally in Pushbullet.
* `Ephemeral` -- messages sent directly into the live event stream. These have
a multitude of uses, e.g. sending SMS via a phone or seeing whether
notifications have occurred on a device.
* `Device` -- representation of a device.
* `User` -- representation of a user.
* `Permanant` -- this is an undocumented type in the Pushbullet API. Notably,
SMS threads and messages are permanents.
Some of these types come in two flavors: `New` and `Existing`. This is
signalled by a type index coming from a datakind.
