 ## 0.23.0 (2023-XX-XX)
 
-This release is 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.
-
-**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, we have rewritten over [10000 lines of code](https://github.com/juanfont/headscale/compare/b01f1f1867136d9b2d7b1392776eb363b482c525...main) 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)

-  - 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/running-headscale-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)

-# 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.

-control server.
-Headscale's goal is to provide self-hosters and hobbyists with an open-source
-server they can use for their projects and labs.
-It implements a narrow scope, a single Tailnet, suitable for a personal use, or a small

-# Frequently Asked Questions
-
-## What is the design goal of headscale?
-
-`headscale` aims to implement a self-hosted, open source alternative to the [Tailscale](https://tailscale.com/)
-control server.
-`headscale`'s goal is to provide self-hosters and hobbyists with an open-source
-server they can use for their projects and labs.
-It implements a narrow scope, a _single_ Tailnet, suitable for a personal use, or a small
-open-source organisation.
-
-## How can I contribute?
-
-Headscale is "Open Source, acknowledged contribution", this means that any
-contribution will have to be discussed with the Maintainers before being submitted.
-
-Headscale is open to code contributions for bug fixes without discussion.
-
-If you find mistakes in the documentation, please also submit a fix to the documentation.
-
-## Why is 'acknowledged contribution' the chosen model?
-
-Both maintainers have full-time jobs and families, and we want to avoid burnout. We also want to avoid frustration from contributors when their PRs are not accepted.
-
-We are more than happy to exchange emails, or to have dedicated calls before a PR is submitted.
-
-## When/Why is Feature X going to be implemented?
-
-We don't know. We might be working on it. If you want to help, please send us a PR.
-
-Please be aware that there are a number of reasons why we might not accept specific contributions:
-
-- It is not possible to implement the feature in a way that makes sense in a self-hosted environment.
-- Given that we are reverse-engineering Tailscale to satisfy our own curiosity, we might be interested in implementing the feature ourselves.
-- You are not sending unit and integration tests with it.
-
-## Do you support Y method of deploying Headscale?
-
-We currently support deploying `headscale` using our binaries and the DEB packages. Both can be found in the
-[GitHub releases page](https://github.com/juanfont/headscale/releases).
-
-In addition to that, there are semi-official RPM packages by the Fedora infra team https://copr.fedorainfracloud.org/coprs/jonathanspw/headscale/
-
-For convenience, we also build Docker images with `headscale`. But **please be aware that we don't officially support deploying `headscale` using Docker**. We have a [Discord channel](https://discord.com/channels/896711691637780480/1070619770942148618) where you can ask for Docker-specific help to the community.
-
-## Why is my reverse proxy not working with Headscale?
-
-We don't know. We don't use reverse proxies with `headscale` ourselves, so we don't have any experience with them. We have [community documentation](https://headscale.net/reverse-proxy/) on how to configure various reverse proxies, and a dedicated [Discord channel](https://discord.com/channels/896711691637780480/1070619818346164324) where you can ask for help to the community.
-
-## Can I use headscale and tailscale on the same machine?
-
-Running headscale on a machine that is also in the tailnet can cause problems with subnet routers, traffic relay nodes, and MagicDNS. It might work, but it is not supported.
