Tinyauth v5.1.0

Hey everyone, this is Tinyauth v5.1.0, and Tinyauth is now officially OpenID Connect™ Certified thanks to the amazing help of @Rycochet and @scottmckendry. Additionally, this release brings a lot of improvements in access controls (deny-by-default and Kubernetes yay!), LDAP and general UX improvements. It also addresses some important security vulnerabilities (1, 2, 3) that were responsibly disclosed by our amazing community. Have fun ;)

OpenID Certified

yep, we using that everywhere now

[!NOTE] Tinyauth has moved! All repositories now live under the new Tinyauth organization. Pull the new image from ghcr.io/tinyauthapp/tinyauth. The old image under my personal account will no longer be updated, so switch over when you can.

[!NOTE] The config file is now a stable feature. Please switch your configuration file flag to --configfile (or TINYAUTH_CONFIGFILE for environment variables).

[!WARNING] This release contains security fixes. Please update as soon as possible.

[!WARNING] Tinyauth v5.1.0 includes some hardening in the trusted proxies. In case you are using any of the IP ACLs, you may need to specify your proxy IP in TINYAUTH_AUTH_TRUSTEDPROXIES.
