The largest changes were around the hoauth2 interface:
The OAuth2 type replaced all of its ByteString fields with either Text
or URI. This is a huge improvement. The fields that are now Text are the
type we had them in anyway. The fields that are now URI are type safe
and easier to manipulate. For example, we were doing very unsafe query
string manipulations looking for raw ? or & values, but now we can work
with tuples in a well-typed property.
Additionally the AccessToken type was upgraded to OAuth2Token with an
accessToken field, and the simple Either ByteString a results were
replaced by a real OAuth2Error type. This required changes to our
InvalidProfileResponse mechanism to support.
To make working with uri-bytestring more convenient, an Extension
library was added with some useful instances and helper functions. This
library may be upstreamed at some point.
Marks "location" as Maybe in GitHub responses. Without this, users could
experience an InvalidProfileResponse error when missing.
Also fixes cases where fields were Maybe, but the (.:?) combinator was
not being used in the parser.
