v3.1.0

News:

• Possible to configure lifetimes for tokens issued by the OpenID Connect frontend.
• Metadata generation script (satosa-saml-metadata) has two flags: --split-frontend and --split-backend for producing metadata files with just one EntityDescriptor per file instead of one file with all entities nested in a EntititesDescriptor.

Fixes:

• Correctly handle UI Info in mirrored target IdP's with logo's that don't specify the (optional) language attribute.
