-## 0.24.0 (2024-01-17)
-
-### Security fix: OIDC changes in Headscale 0.24.0
-
-The following issue _only_ affects Headscale installations which authenticate
-with OIDC.
-
-_Headscale v0.23.0 and earlier_ identified OIDC users by the "username" part of
-their email address (when `strip_email_domain: true`, the default) or whole
-email address (when `strip_email_domain: false`).
-
-Depending on how Headscale and your Identity Provider (IdP) were configured,
-only using the `email` claim could allow a malicious user with an IdP account to
-take over another Headscale user's account, even when
-`strip_email_domain: false`.
-
-This would also cause a user to lose access to their Headscale account if they
-changed their email address.
-
-_Headscale v0.24.0_ now identifies OIDC users by the `iss` and `sub` claims.
-[These are guaranteed by the OIDC specification to be stable and unique](https://openid.net/specs/openid-connect-core-1_0.html#ClaimStability),
-even if a user changes email address. A well-designed IdP will typically set
-`sub` to an opaque identifier like a UUID or numeric ID, which has no relation
-to the user's name or email address.
-
-Headscale v0.24.0 and later will also automatically update profile fields with
-OIDC data on login. This means that users can change those details in your IdP,
-and have it populate to Headscale automatically the next time they log in.
-However, this may affect the way you reference users in policies.
-
-Headscale v0.23.0 and earlier never recorded the `iss` and `sub` fields, so all
-legacy (existing) OIDC accounts _need to be migrated_ to be properly
-secured.
-
-#### What do I need to do to migrate?
-
-Headscale v0.24.0 has an automatic migration feature, which is enabled by
-default (`map_legacy_users: true`). **This will be disabled by default in a
-future version of Headscale – any unmigrated users will get new accounts.**
-
-The migration will mostly be done automatically, with one exception. If your
-OIDC does not provide an `email_verified` claim, Headscale will ignore the
-`email`. This means that either the administrator will have to mark the user
-emails as verified, or ensure the users verify their emails. Any unverified
-emails will be ignored, meaning that the users will get new accounts instead
-of being migrated.
-
-After this exception is ensured, make all users log into Headscale with their
-account, and Headscale will automatically update the account record. This will
-be transparent to the users.
-
-When all users have logged in, you can disable the automatic migration by
-setting `map_legacy_users: false` in your configuration file.
-
-Please note that `map_legacy_users` will be set to `false` by default in v0.25.0
-and the migration mechanism will be removed in v0.26.0.
-
-<details>
-
-<summary>What does automatic migration do?</summary>
-
-##### What does automatic migration do?
-
-When automatic migration is enabled (`map_legacy_users: true`), Headscale will
-first match an OIDC account to a Headscale account by `iss` and `sub`, and then
-fall back to matching OIDC users similarly to how Headscale v0.23.0 did:
-
-- If `strip_email_domain: true` (the default): the Headscale username matches
-  the "username" part of their email address.
-- If `strip_email_domain: false`: the Headscale username matches the _whole_
-  email address.
-
-On migration, Headscale will change the account's username to their
-`preferred_username`. **This could break any ACLs or policies which are
-configured to match by username.**
-
-Like with Headscale v0.23.0 and earlier, this migration only works for users who
-haven't changed their email address since their last Headscale login.
-
-A _successful_ automated migration should otherwise be transparent to users.
-
-Once a Headscale account has been migrated, it will be _unavailable_ to be
-matched by the legacy process. An OIDC login with a matching username, but
-_non-matching_ `iss` and `sub` will instead get a _new_ Headscale account.
-
-Because of the way OIDC works, Headscale's automated migration process can
-_only_ work when a user tries to log in after the update.
-
-Legacy account migration should have no effect on new installations where all
-users have a recorded `sub` and `iss`.
-
-</details>
-
-<details>
-
-<summary>What happens when automatic migration is disabled?</summary>
-
-##### What happens when automatic migration is disabled?
-
-When automatic migration is disabled (`map_legacy_users: false`), Headscale will
-only try to match an OIDC account to a Headscale account by `iss` and `sub`.
-
-If there is no match, it will get a _new_ Headscale account – even if there was
-a legacy account which _could_ have matched and migrated.
-
-We recommend new Headscale users explicitly disable automatic migration – but it
-should otherwise have no effect if every account has a recorded `iss` and `sub`.
-
-When automatic migration is disabled, the `strip_email_domain` setting will have
-no effect.
-
-</details>
-
-Special thanks to @micolous for reviewing, proposing and working with us on
-these changes.
-
-#### Other OIDC changes
-
-Headscale now uses
-[the standard OIDC claims](https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims)
-to populate and update user information every time they log in:
-
-| Headscale profile field | OIDC claim           | Notes / examples                                                                                          |
-| ----------------------- | -------------------- | --------------------------------------------------------------------------------------------------------- |
-| email address           | `email`              | Only used when `"email_verified": true`                                                                   |
-| display name            | `name`               | eg: `Sam Smith`                                                                                           |
-| username                | `preferred_username` | Varies depending on IdP and configuration, eg: `ssmith`, `ssmith@idp.example.com`, `\\example.com\ssmith` |
-| profile picture         | `picture`            | URL to a profile picture or avatar                                                                        |
-
-These should show up nicely in the Tailscale client.
-
-This will also affect the way you
-[reference users in policies](https://github.com/juanfont/headscale/pull/2205).

-## 0.23.0 (2024-09-18)
-
-This release was intended to be mainly a code reorganisation and refactoring,
-significantly improving the maintainability of the codebase. This should allow
-us to improve further and make it easier for the maintainers to keep on top of
-the project. However, as you all have noticed, it turned out to become a much
-larger, much longer release cycle than anticipated. It has ended up to be a
-release with a lot of rewrites and changes to the code base and functionality of
-Headscale, cleaning up a lot of technical debt and introducing a lot of
-improvements. This does come with some breaking changes,
-
-**Please remember to always back up your database between versions**
-
-#### Here is a short summary of the broad topics of changes:
-
-Code has been organised into modules, reducing use of global variables/objects,
-isolating concerns and “putting the right things in the logical place”.
-
-The new
-[policy](https://github.com/juanfont/headscale/tree/main/hscontrol/policy) and
-[mapper](https://github.com/juanfont/headscale/tree/main/hscontrol/mapper)
-package, containing the ACL/Policy logic and the logic for creating the data
-served to clients (the network “map”) has been rewritten and improved. This
-change has allowed us to finish SSH support and add additional tests throughout
-the code to ensure correctness.
-
-The
-[“poller”, or streaming logic](https://github.com/juanfont/headscale/blob/main/hscontrol/poll.go)
-has been rewritten and instead of keeping track of the latest updates, checking
-at a fixed interval, it now uses go channels, implemented in our new
-[notifier](https://github.com/juanfont/headscale/tree/main/hscontrol/notifier)
-package and it allows us to send updates to connected clients immediately. This
-should both improve performance and potential latency before a client picks up
-an update.
-
-Headscale now supports sending “delta” updates, thanks to the new mapper and
-poller logic, allowing us to only inform nodes about new nodes, changed nodes
-and removed nodes. Previously we sent the entire state of the network every time
-an update was due.
-
-While we have a pretty good
-[test harness](https://github.com/search?q=repo%3Ajuanfont%2Fheadscale+path%3A_test.go&type=code)
-for validating our changes, the changes came down to
-[284 changed files with 32,316 additions and 24,245 deletions](https://github.com/juanfont/headscale/compare/b01f1f1867136d9b2d7b1392776eb363b482c525...ed78ecd)
-and bugs are expected. We need help testing this release. In addition, while we
-think the performance should in general be better, there might be regressions in
-parts of the platform, particularly where we prioritised correctness over speed.
-
-There are also several bugfixes that has been encountered and fixed as part of
-implementing these changes, particularly after improving the test harness as
-part of adopting [#1460](https://github.com/juanfont/headscale/pull/1460).
-
-### BREAKING
-
-- Code reorganisation, a lot of code has moved, please review the following PRs
-  accordingly [#1473](https://github.com/juanfont/headscale/pull/1473)
-- Change the structure of database configuration, see
-  [config-example.yaml](./config-example.yaml) for the new structure.
-  [#1700](https://github.com/juanfont/headscale/pull/1700)
-  - Old structure has been remove and the configuration _must_ be converted.
-  - Adds additional configuration for PostgreSQL for setting max open, idle
-    connection and idle connection lifetime.
-- API: Machine is now Node
-  [#1553](https://github.com/juanfont/headscale/pull/1553)
-- Remove support for older Tailscale clients
-  [#1611](https://github.com/juanfont/headscale/pull/1611)
-  - The oldest supported client is 1.42
-- Headscale checks that _at least_ one DERP is defined at start
-  [#1564](https://github.com/juanfont/headscale/pull/1564)
-  - If no DERP is configured, the server will fail to start, this can be because
-    it cannot load the DERPMap from file or url.
-- Embedded DERP server requires a private key
-  [#1611](https://github.com/juanfont/headscale/pull/1611)
-  - Add a filepath entry to
-    [`derp.server.private_key_path`](https://github.com/juanfont/headscale/blob/b35993981297e18393706b2c963d6db882bba6aa/config-example.yaml#L95)
-- Docker images are now built with goreleaser (ko)
-  [#1716](https://github.com/juanfont/headscale/pull/1716)
-  [#1763](https://github.com/juanfont/headscale/pull/1763)
-  - Entrypoint of container image has changed from shell to headscale, require
-    change from `headscale serve` to `serve`
-  - `/var/lib/headscale` and `/var/run/headscale` is no longer created
-    automatically, see [container docs](./docs/setup/install/container.md)
-- Prefixes are now defined per v4 and v6 range.
-  [#1756](https://github.com/juanfont/headscale/pull/1756)
-  - `ip_prefixes` option is now `prefixes.v4` and `prefixes.v6`
-  - `prefixes.allocation` can be set to assign IPs at `sequential` or `random`.
-    [#1869](https://github.com/juanfont/headscale/pull/1869)
-- MagicDNS domains no longer contain usernames []()
-  - This is in preparation to fix Headscales implementation of tags which
-    currently does not correctly remove the link between a tagged device and a
-    user. As tagged devices will not have a user, this will require a change to
-    the DNS generation, removing the username, see
-    [#1369](https://github.com/juanfont/headscale/issues/1369) for more
-    information.
-  - `use_username_in_magic_dns` can be used to turn this behaviour on again, but
-    note that this option _will be removed_ when tags are fixed.
-    - dns.base_domain can no longer be the same as (or part of) server_url.
-    - This option brings Headscales behaviour in line with Tailscale.
-- YAML files are no longer supported for headscale policy.
-  [#1792](https://github.com/juanfont/headscale/pull/1792)
-  - HuJSON is now the only supported format for policy.
-- DNS configuration has been restructured
-  [#2034](https://github.com/juanfont/headscale/pull/2034)
-  - Please review the new [config-example.yaml](./config-example.yaml) for the
-    new structure.

-    - Rejecting connections **are not supported**, meaning that if you enable
-      SSH, then assume that _all_ `ssh` connections **will be allowed**.
-    - If you decided to try this feature, please carefully managed permissions
-      by blocking port `22` with regular ACLs or do _not_ set `--ssh` on your
-      clients.
-    - We are currently improving our testing of the SSH ACLs, help us get an
-      overview by testing and giving feedback.
-  - This feature should be considered dangerous and it is disabled by default.
-    Enable by setting `HEADSCALE_EXPERIMENTAL_FEATURE_SSH=1`.

-# Contributing
-
-Headscale is "Open Source, acknowledged contribution", this means that any contribution will have to be discussed with the maintainers before being added to the project.
-This model has been chosen to reduce the risk of burnout by limiting the maintenance overhead of reviewing and validating third-party code.
-
-## Why do we have this model?
-
-Headscale has a small maintainer team that tries to balance working on the project, fixing bugs and reviewing contributions.
-
-When we work on issues ourselves, we develop first hand knowledge of the code and it makes it possible for us to maintain and own the code as the project develops.
-
-Code contributions are seen as a positive thing. People enjoy and engage with our project, but it also comes with some challenges; we have to understand the code, we have to understand the feature, we might have to become familiar with external libraries or services and we think about security implications. All those steps are required during the reviewing process. After the code has been merged, the feature has to be maintained. Any changes reliant on external services must be updated and expanded accordingly.
-
-The review and day-1 maintenance adds a significant burden on the maintainers. Often we hope that the contributor will help out, but we found that most of the time, they disappear after their new feature was added.
-
-This means that when someone contributes, we are mostly happy about it, but we do have to run it through a series of checks to establish if we actually can maintain this feature.
-
-## What do we require?
-
-A general description is provided here and an explicit list is provided in our pull request template.
-
-All new features have to start out with a design document, which should be discussed on the issue tracker (not discord). It should include a use case for the feature, how it can be implemented, who will implement it and a plan for maintaining it.
-
-All features have to be end-to-end tested (integration tests) and have good unit test coverage to ensure that they work as expected. This will also ensure that the feature continues to work as expected over time. If a change cannot be tested, a strong case for why this is not possible needs to be presented.
-
-The contributor should help to maintain the feature over time. In case the feature is not maintained probably, the maintainers reserve themselves the right to remove features they redeem as unmaintainable. This should help to improve the quality of the software and keep it in a maintainable state.
-
-## Bug fixes
-
-Headscale is open to code contributions for bug fixes without discussion.
-
-## Documentation
-
-If you find mistakes in the documentation, please submit a fix to the documentation.
