# Vx.x.x (Pre-release)

## Release Highlights

## Important Notes

- [#453](https://github.com/oauth2-proxy/oauth2-proxy/pull/453) Responses to endpoints with a proxy prefix will now return headers for preventing browser caching.

## Breaking Changes

- [#464](https://github.com/oauth2-proxy/oauth2-proxy/pull/464) Migration from Pusher to independent org may have introduced breaking changes for your environment.
  - See the changes listed below for PR [#464](https://github.com/oauth2-proxy/oauth2-proxy/pull/464) for full details
  - Binaries renamed from `oauth2_proxy` to `oauth2-proxy`
- [#440](https://github.com/oauth2-proxy/oauth2-proxy/pull/440) Switch Azure AD Graph API to Microsoft Graph API
  - The Azure AD Graph API has been [deprecated](https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-graph-api) and is being replaced by the Microsoft Graph API.
    If your application relies on the access token being passed to it to access the Azure AD Graph API, you should migrate your application to use the Microsoft Graph API.
    Existing behaviour can be retained by setting  `-resource=https://graph.windows.net`.
- [#484](https://github.com/oauth2-proxy/oauth2-proxy/pull/484) Configuration loading has been replaced with Viper and PFlag
  - Flags now require a `--` prefix before the option
  - Previously flags allowed either `-` or `--` to prefix the option name
  - Eg `-provider` must now be `--provider`
- [#487](https://github.com/oauth2-proxy/oauth2-proxy/pull/487) Switch flags to StringSlice instead of StringArray
  - Options that take multiple arguments now split strings on commas if present
  - Eg `--foo=a,b,c,d` would result in the values `a`, `b`, `c` and `d` instead of a single `a,b,c,d` value as before
- [#535](https://github.com/oauth2-proxy/oauth2-proxy/pull/535) Drop support for pre v3.1 cookies
  - The encoding for session cookies was changed starting in v3.1.0, support for the previous encoding is now dropped
  - If you are upgrading from a version earlier than this, please upgrade via a version between v3.1.0 and v5.1.1
- [#537](https://github.com/oauth2-proxy/oauth2-proxy/pull/537) Drop Fallback to Email if User not set
  - Previously, when a session was loaded, if the User was not set, it would be replaced by the Email.
    This behaviour was inconsistent as it required the session to be stored and then loaded to function properly.
  - This behaviour has now been removed and the User field will remain empty if it was not set when the session was saved.
  - In some scenarios `X-Forwarded-User` will now be empty. Use `X-Forwarded-Email` instead.
  - In some scenarios, this may break setting Basic Auth on upstream or responses.
    Use `--prefer-email-to-user` to restore falling back to the Email in these cases.

  - This PR adds the IDToken into the session for the Azure provider allowing requests to a backend to be identified as a specific user. As a consequence, if you are using a cookie to store the session the cookie will now exceed the 4kb size limit and be split into multiple cookies. This can cause problems when using nginx as a proxy, resulting in no cookie being passed at all. Either increase the proxy_buffer_size in nginx or implement the redis session storage (see https://oauth2-proxy.github.io/oauth2-proxy/configuration#redis-storage)

# v4.0.0

## Release Highlights
- Documentation is now on a [microsite](https://oauth2-proxy.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

- [#231](https://github.com/oauth2-proxy/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/oauth2-proxy/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/oauth2-proxy/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/oauth2-proxy/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.

# v3.1.0

## Release highlights

- Introduction of ARM releases and and general improvements to Docker builds
- Improvements to OIDC provider allowing pass-through of ID Tokens
- Multiple redirect domains can now be whitelisted
- Streamed responses are now flushed periodically

## Important notes

- If you have been using [#bitly/621](https://github.com/bitly/oauth2_proxy/pull/621)
  and have cookies larger than the 4kb limit,
  the cookie splitting pattern has changed and now uses `_` in place of `-` when
  indexing cookies.
  This will force users to reauthenticate the first time they use `v3.1.0`.
- Streamed responses will now be flushed every 1 second by default.
  Previously streamed responses were flushed only when the buffer was full.
  To retain the old behaviour set `--flush-interval=0`.
  See [#23](https://github.com/oauth2-proxy/oauth2-proxy/pull/23) for further details.
