Second release candidate for SImpleSAMLphp 2.0

[Thijs Kinkhorst]

Hi all,

As some of you may know, we've been working on SimpleSAMLphp 2.0, which
brings a lot of improvements to the codebase and at the same time cleans
up a significant amount of legacy.

After the feedback on the first release candidate (many thanks to those
that helped test it), a second release candidate is now available. We
really appriciate any testing and verification so we can make the 2.0
release the best it can be.

It can be downloaded here:
https://simplesamlphp.org/download/

Do take note of the upgrade notes as quite some deprecated things have
been removed:
https://simplesamlphp.org/docs/devel/simplesamlphp-upgrade-notes-2.0.html

We welcome any feedback, issues or improvements to the upgrade nodes via
an issue or a pull request on Github.


On behalf of the team,
Thijs Kinkhorst
