chore: v0.4.0

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.

+### 0.4.0 (January 6, 2025)
+- Switched from Remix.run to React-Router
+- Fixed an issue where some config fields were marked as required even if they weren't (fixes [#66](https://github.com/tale/headplane/issues/66))
+- Fixed an issue where the toasts would be obscured by the footer (fixes [#68](https://github.com/tale/headplane/issues/68))
+- The footer now blurs your Headscale URL as a privacy measure
+- Updated to the next stable beta of the React Compiler
+- Changed `/healthz` to use a well-known endpoint instead of trying an invalid API key
+- Support `OIDC_REDIRECT_URI` to force a specific redirect URI
+- Redo the OIDC integration for better error handling and configuration
+- Gracefully handle when Headscale is unreachable instead of crashing the dashboard
+- Reusable Pre-Auth Keys no longer show expired when used (PR [#88](https://github.com/tale/headplane/pull/88))
+- Tweaked some CSS issues in the UI
+
+### 0.3.9 (December 6, 2024)
+- Fixed a race condition bug in the OIDC validation code
+
+### 0.3.8 (December 6, 2024)
+- Added a little HTML footer to show the login page and link to a donation page.
+- Allow creating pre-auth keys that expire past 90 days (fixes [#58](https://github.com/tale/headplane/issues/58))
+- Validates OIDC config and ignores validation if specified via variables or Headscale config (fixes [#63](https://github.com/tale/headplane/issues/63))
+
+### 0.3.7 (November 30, 2024)
+- Allow customizing the OIDC token endpoint auth method via `OIDC_CLIENT_SECRET_METHOD` (fixes [#57](https://github.com/tale/headplane/issues/57))
+- Added a `/healthz` endpoint for Kubernetes and other health checks (fixes [#59](https://github.com/tale/headplane/issues/59))
+- Allow `HEADSCALE_PUBLIC_URL` to be set if `HEADSCALE_URL` points to a different internal address (fixes [#60](https://github.com/tale/headplane/issues/60))
+- Fixed an issue where the copy machine registration command had a typo.
+
+### 0.3.6 (November 20, 2024)
+- Fixed an issue where select dropdowns would not scroll (fixes [#53](https://github.com/tale/headplane/issues/53))
+- Added a button to copy the machine registration command to the clipboard (fixes [#52](https://github.com/tale/headplane/issues/52))
+
+### 0.3.5 (November 8, 2024)
+- Quickfix a bug where environment variables are ignored on the server.
+- Remove a nagging error about missing cookie since that happens when signed out.
+
+### 0.3.4 (November 7, 2024)
+- Clicking on the machine name in the users page now takes you to the machine overview page.
+- Completely rebuilt the production server to work better outside of Docker and be lighter. More specifically, we've switched from the `@remix-run/serve` package to our own custom built server.
+- Fixed a bunch of silly issues introduced by me not typechecking the codebase.
+- Improve documentation and support when running Headplane outside of Docker.
+- Removing Split DNS records will no longer result in an error (fixes [#40](https://github.com/tale/headplane/issues/40))
+- Removing the last ACL tag on a machine no longer results in an error (fixes [#41](https://github.com/tale/headplane/issues/41))
+- Added full support for Exit Nodes in the UI and redesigned the machines page (fixes [#36](https://github.com/tale/headplane/issues/36))
+- Added a basic check to see if the API keys passed via cookies are invalid.
+
+### 0.3.3 (October 28, 2024)
+- Added the ability to load a `.env` file from the PWD when `LOAD_ENV_FILE=true` is set as an environment variable.
+- Fixed an issue where non-English languages could not create Pre-auth keys due to a localization error
+- Improved ACL editor performance by switching back to CodeMirror 6
+- Fixed an issue where editing the ACL policy would cause it to revert on the UI (fixes [#34](https://github.com/tale/headplane/issues/34))
+- Updated to the next stable beta of the React 19 Compiler ([See More](https://react.dev/learn/react-compiler))
+
+### 0.3.2 (October 11, 2024)
+- Implement the ability to create and expire pre-auth keys (fixes [#22](https://github.com/tale/headplane/issues/22))
+- Fix machine registration not working as expected (fixes [#27](https://github.com/tale/headplane/issues/27))
+- Removed more references to usernames in MagicDNS hostnames (fixes [#35](https://github.com/tale/headplane/issues/35))
+- Handle `null` values on machine expiry when using a database like PostgreSQL.
+- Use `X-Forwarded-Proto` and `Host` headers for building the OIDC callback URL.
+
+### 0.3.1 (October 3, 2024)
+- Fixed the Docker integration to properly support custom socket paths. This regressed at some point previously.
+- Allow you to register a machine using machine keys (`nodekey:...`) on the machines page.
+- Added the option for debug logs with the `DEBUG=true` environment variable.
+
 ### 0.3.0 (September 25, 2024)
 - Bumped the minimum supported version of Headscale to 0.23.
 - Updated the UI to respect `dns.use_username_in_magic_dns`.
