chore: v0.4.1

This includes setting a custom redirect URI, handling errors, and using a better library.
As an API decision I've also disabled per session API keys as it clutters up too much.

+- Fixed some type issues where `Date` was being used instead of `string` for timestamps.
+
+### 0.1.7 (May 30, 2024)
+- Added support for the `HEADSCALE_INTEGRATION` variable to allow for advanced integration without Docker.
+- Fixed a bug where the `expiry` field on the Headscale configuration could cause crashes.
+- Made the strict configuration loader more lenient to allow for more flexibility.
+- Added `HEADSCALE_CONFIG_UNSTRICT`=true to revert back to a weaker configuration loader.
+- Headplane's context now only loads once at start instead of being lazy-loaded.
+- Improved logging and error propagation so that it's easier to debug issues.
+
+### 0.1.6 (May 22, 2024)

+
+### 0.1.5 (May 20, 2024)
+- Robust configuration handling with fallbacks based on the headscale source.
+- Support for `client_secret_path` on configuration file based OIDC.
+- `DISABLE_API_KEY_LOGIN` now works as expected (non 'true' values work).
+- `API_KEY` is renamed to `ROOT_API_KEY` for better clarity (old variable still works).
+- Fixed button responders not actually being invoked (should fix the ACL page).
+
+### 0.1.4 (May 15, 2024)
+
+- Users can now be created, renamed, and deleted on the users page.

+
+### 0.1.3 (May 4, 2024)

+
+- Added support for renaming, expiring, removing, and managing the routes of a machine.
+- Implemented an expiry check for machines which now reflect on the machine table.
+- Fixed an issue where `HEADSCALE_CONTAINER` was needed to start even without the Docker integration.
+- Removed the requirement for the root `API_KEY` unless OIDC was being used for authentication.
+- Switched to [React Aria](https://react-spectrum.adobe.com/react-aria/) for better accessibility support.
+- Cleaned up various different UI inconsistencies and copied components that could've been abstracted.
+- Added a changelog for any new versions going forward.

 Headscale is a self-hosted version of the Tailscale control server, however, it currently lacks a first-party web UI.
-This is a relatively tiny Remix app that aims to provide a usable GUI for the Headscale server.
-It's still very early in it's development, however these are some of the features that are planned.
+Headplane aims to solve this issue by providing a GUI that can deeply integrate with the Headscale server.
+It's able to replicate nearly all of the functions of the official Tailscale SaaS UI, including:
 
-- [ ] Editable tags, machine names, users, etc
-- [ ] ACL control through Docker integration
-- [x] OIDC based login for the web UI
-- [x] Automated API key regeneration
-- [x] Editable headscale configuration
+- Machine/Node expiry, network routing, name, and owner management
+- Access Control List (ACL) and tagging configuration
+- Support for OpenID Connect (OIDC) as a login provider
+- DNS and *safe* Headscale configuration management
 
 ## Deployment
-- If you run Headscale in a Docker container, see the [Advanced Deployment](/docs/Advanced-Integration.md) guide.
-- If you run Headscale natively, see the [Basic Deployment](/docs/Basic-Integration.md) guide.
+> For more configuration options, refer to the [Configuration](/docs/Configuration.md) guide.
+
+For fully-featured deployments, see the [Advanced Deployment](/docs/Advanced-Integration.md) guide.
+This includes automatic management of ACLs, DNS settings, and Headscale configuration.
+*This is the closest experience to the Tailscale UI that can be achieved with Headscale and Headplane.*
+*If you aren't sure which one to pick, we recommend this.*
+
+If your environment is not able to support the advanced deployment, you can still use the basic deployment.
+For basic deployments, see the [Basic Deployment](/docs/Basic-Integration.md) guide.
+It does not include automatic management of ACLs, DNS settings, or the Headscale configuration,
+instead requiring manual editing and reloading when making changes.
 
 ## Contributing
 If you would like to contribute, please install a relatively modern version of Node.js and PNPM.
