Pomerium v0.5.1 is released

[Bobby DeSimone]

We just released Pomerium v0.5.1, a minor point and patch release! A few of highlights are:

- Improved session handling. User sessions are now now route-scoped and managed by a transparent, signed JSON Web Token (JWT).

- Managed routes no longer must reside under the same subdomain. Access can be delegated to any route, on any domain.

- Programmatic access is now delegated using standard OAuth2 flow, uses JWTs, and enables renewable sessions.

- User dashboard includes additional user context fields like profile picture, first and last name, and other available identity claims.

Please review the upgrade guide and changelog for a complete list of changes and improvements.

You can download binary and source distributions from github. Or you can pull the `v0.5.1` container image from dockerhub.

Thank you to everyone who contributed to this release.
