 # Vx.x.x (Pre-release)
 
+## Changes since v4.0.0
+
+- [#227](https://github.com/pusher/oauth2_proxy/pull/227) Add Keycloak provider (@Ofinka)
+
+# v4.0.0
+
+## Release Highlights
+- Documentation is now on a [microsite](https://pusher.github.io/oauth2_proxy/)
+- Health check logging can now be disabled for quieter logs
+- Authorization Header JWTs can now be verified by the proxy to skip authentication for machine users
+- Sessions can now be stored in Redis. This reduces refresh failures and uses smaller cookies (Recommended for those using OIDC refreshing)
+- Logging overhaul allows customisable logging formats
+
+## Important Notes
+- This release includes a number of breaking changes that will require users to
+reconfigure their proxies. Please read the Breaking Changes below thoroughly.
+
 ## Breaking Changes
 
-- [#146](https://github.com/pusher/oauth2_proxy/pull/146) Use full email address as `User` if the auth response did not contain a `User` field (@gargath)
+- [#231](https://github.com/pusher/oauth2_proxy/pull/231) Rework GitLab provider
+  - This PR changes the configuration options for the GitLab provider to use
+  a self-hosted instance. You now need to specify a `-oidc-issuer-url` rather than
+  explicit `-login-url`, `-redeem-url` and `-validate-url` parameters.
+- [#186](https://github.com/pusher/oauth2_proxy/pull/186) Make config consistent
+  - This PR changes configuration options so that all flags have a config counterpart
+  of the same name but with underscores (`_`) in place of hyphens (`-`).
+  This change affects the following flags:
+  - The `--tls-key` flag is now `--tls-key-file` to be consistent with existing
+  file flags and the existing config and environment settings
+  - The `--tls-cert` flag is now `--tls-cert-file` to be consistent with existing
+  file flags and the existing config and environment settings
+  This change affects the following existing configuration options:
+  - The `proxy-prefix` option is now `proxy_prefix`.
+  This PR changes environment variables so that all flags have an environment
+  counterpart of the same name but capitalised, with underscores (`_`) in place
+  of hyphens (`-`) and with the prefix `OAUTH2_PROXY_`.
+  This change affects the following existing environment variables:
+  - The `OAUTH2_SKIP_OIDC_DISCOVERY` environment variable is now `OAUTH2_PROXY_SKIP_OIDC_DISCOVERY`.
+  - The `OAUTH2_OIDC_JWKS_URL` environment variable is now `OAUTH2_PROXY_OIDC_JWKS_URL`.
+- [#146](https://github.com/pusher/oauth2_proxy/pull/146) Use full email address as `User` if the auth response did not contain a `User` field
   - This change modifies the contents of the `X-Forwarded-User` header supplied by the proxy for users where the auth response from the IdP did not contain
     a username.
     In that case, this header used to only contain the local part of the user's email address (e.g. `john.doe` for `john.doe@example.com`) but now contains
     the user's full email address instead.
+- [#170](https://github.com/pusher/oauth2_proxy/pull/170) Pre-built binary tarballs changed format
+  - The pre-built binary tarballs again match the format of the [bitly](https://github.com/bitly/oauth2_proxy) repository, where the unpacked directory
+    has the same name as the tarball and the binary is always named `oauth2_proxy`. This was done to restore compatibility with third-party automation
+    recipes like https://github.com/jhoblitt/puppet-oauth2_proxy.

+  the `-skip-jwt-bearer-token` options. (@brianv0)
+  - Additional verifiers can be configured via the `-extra-jwt-issuers` flag if the JWT issuers is either an OpenID provider or has a JWKS URL
+  (e.g. `https://example.com/.well-known/jwks.json`).
+- [#180](https://github.com/pusher/oauth2_proxy/pull/180) Minor refactor of core proxying path (@aeijdenberg).

+    - `-session-store-type=redis` Sets the store type to redis
+    - `-redis-connection-url` Sets the Redis connection URL
+    - `-redis-use-sentinel=true` Enables Redis Sentinel support

+  - Introduces the concept of a session ticket. Tickets are composed of the cookie name, a session ID, and a secret.
+  - Redis Sessions are stored encrypted with a per-session secret

+The OpenID Connect Provider (OIDC) can also be used to connect to other Identity Providers such as Okta. To configure the OIDC provider for Okta, perform
+the following steps:
+
+#### Configuring the OIDC Provider with Okta
+
+1. Log in to Okta using an administrative account. It is suggested you try this in preview first, `example.oktapreview.com`
+2. (OPTIONAL) If you want to configure authorization scopes and claims to be passed on to multiple applications,
+you may wish to configure an authorization server for each application. Otherwise, the provided `default` will work.
+* Navigate to **Security** then select **API**
+* Click **Add Authorization Server**, if this option is not available you may require an additional license for a custom authorization server.
+* Fill out the **Name** with something to describe the application you are protecting. e.g. 'Example App'.
+* For **Audience**, pick the URL of the application you wish to protect: https://example.corp.com
+* Fill out a **Description**
+* Add any **Access Policies** you wish to configure to limit application access.
+* The default settings will work for other options.
+[See Okta documentation for more information on Authorization Servers](https://developer.okta.com/docs/guides/customize-authz-server/overview/)
+3. Navigate to **Applications** then select **Add Application**.
+* Select **Web** for the **Platform** setting.
+* Select **OpenID Connect** and click **Create**
+* Pick an **Application Name** such as `Example App`.
+* Set the **Login redirect URI** to `https://example.corp.com`.
+* Under **General** set the **Allowed grant types** to `Authorization Code` and `Refresh Token`.
+* Leave the rest as default, taking note of the `Client ID` and `Client Secret`.
+* Under **Assignments** select the users or groups you wish to access your application.
+4. Create a configuration file like the following:
+
+```
+provider = "oidc"
+redirect_url = "https://example.corp.com"
+oidc_issuer_url = "https://corp.okta.com/oauth2/abCd1234"
+upstreams = [
+    "https://example.corp.com"
+]
+email_domains = [
+    "corp.com"
+]
+client_id = "XXXXX"
+client_secret = "YYYYY"
+pass_access_token = true
+cookie_secret = "ZZZZZ"
+skip_provider_button = true
+```
+
+The `oidc_issuer_url` is based on URL from your **Authorization Server**'s **Issuer** field in step 2, or simply https://corp.okta.com
+The `client_id` and `client_secret` are configured in the application settings.
+Generate a unique `client_secret` to encrypt the cookie.
+
+Then you can start the oauth2_proxy with `./oauth2_proxy -config /etc/example.cfg`

-- `OAUTH2_PROXY_COOKIE_REFRESH`
-- `OAUTH2_PROXY_SIGNATURE_KEY`
+This is particularly useful for storing secrets outside of a configuration file

 - Since multiple requests can be made concurrently to the OAuth2 Proxy, this session implementation

 users to re-authenticate
+
+
+### Redis Storage
+
+The Redis Storage backend stores sessions, encrypted, in redis. Instead sending all the information
+back the the client for storage, as in the [Cookie storage](cookie-storage), a ticket is sent back
+to the user as the cookie value instead.
+
+A ticket is composed as the following:
+
+`{CookieName}-{ticketID}.{secret}`
+
+Where:
+
+- The `CookieName` is the OAuth2 cookie name (_oauth2_proxy by default)
+- The `ticketID` is a 128 bit random number, hex-encoded
+- The `secret` is a 128 bit random number, base64url encoded (no padding). The secret is unique for every session.
+- The pair of `{CookieName}-{ticketID}` comprises a ticket handle, and thus, the redis key
+to which the session is stored. The encoded session is encrypted with the secret and stored
+in redis via the `SETEX` command.
+
+Encrypting every session uniquely protects the refresh/access/id tokens stored in the session from
+disclosure.
+
+#### Usage
+
+When using the redis store, specify `--session-store-type=redis` as well as the Redis connection URL, via
+`--redis-connection-url=redis://host[:port][/db-number]`.
+
+You may also configure the store for Redis Sentinel. In this case, you will want to use the 
+`--redis-use-sentinel=true` flag, as well as configure the flags `--redis-sentinel-master-name` 
+and `--redis-sentinel-connection-urls` appropriately.
