Pomerium v0.5.2 is released

[Bobby DeSimone]

We just released Pomerium v0.5.2. 

In this patch release, Pomerium's default session validity period was changed to match that of the upstream identity provider.  If you were experiencing issues with single page applications with short lived sessions, this patch should help mitigate the frequency of logout events. A comprehensive fix to handling XHR request flow is planned for the next minor release, v0.6.0. 

You can download binary and source distributions from Github or grab the `v0.5.2` container image from dockerhub.

As always, thank you to all our users and contributors.
