+- Add the [`s3api` storage backend](./admin/policies.mdx#s3api) to allow Anubis to use S3 API compatible object storage as its storage backend.
+
+## v1.22.0: Yda Hext
+
+> Someone has to make an effort at reconciliation if these conflicts are ever going to end.
+
+In this release, we finally fix the odd number of CPU cores bug, pave the way for lighter weight challenges, make Anubis more adaptable, and more.
+
+### Big ticket items
+
+#### Proof of React challenge
+
+A new ["proof of React"](./admin/configuration/challenges/preact.mdx) has been added. It runs a simple app in React that has several chained hooks. It is much more lightweight than the proof of work check.
+
+#### Smaller features
+
 - The [`segments`](./admin/configuration/expressions.mdx#segments) function was added for splitting a path into its slash-separated segments.
+- Added possibility to disable HTTP keep-alive to support backends not properly handling it.
 - When issuing a challenge, Anubis stores information about that challenge into the store. That stored information is later used to validate challenge responses. This works around nondeterminism in bot rules. ([#917](https://github.com/TecharoHQ/anubis/issues/917))
-- When parsing [Open Graph tags](./admin/configuration/open-graph.mdx), add any URLs found in the responses to a temporary "allow cache" so that social preview images work.
-- Proof of work solving has had a complete overhaul and rethink based on feedback from browser engine developers, frontend experts, and overall performance profiling.
 - One of the biggest sources of lag in Firefox has been eliminated: the use of WebCrypto. Now whenever Anubis detects the client is using Firefox (or Pale Moon), it will swap over to a pure-JS implementation of SHA-256 for speed.
+- Proof of work solving has had a complete overhaul and rethink based on feedback from browser engine developers, frontend experts, and overall performance profiling.
 - Optimize the performance of the pure-JS Anubis solver.
 - Web Workers are stored as dedicated JavaScript files in `static/js/workers/*.mjs`.
 - Pave the way for non-SHA256 solver methods and eventually one that uses WebAssembly (or WebAssembly code compiled to JS for those that disable WebAssembly).
 - Legacy JavaScript code has been eliminated.
+- When parsing [Open Graph tags](./admin/configuration/open-graph.mdx), add any URLs found in the responses to a temporary "allow cache" so that social preview images work.
+- The hard dependency on WebCrypto has been removed, allowing a proof of work challenge to work over plain (unencrypted) HTTP.
+- The Anubis version number is put in the footer of every page.
+- Add a default block rule for Huawei Cloud.
+- Add a default block rule for Alibaba Cloud.
+- Added support to use Traefik forwardAuth middleware.
+- Add X-Request-URI support so that Subrequest Authentication has path support.
+- Added glob matching for `REDIRECT_DOMAINS`. You can pass `*.bugs.techaro.lol` to allow redirecting to anything ending with `.bugs.techaro.lol`. There is a limit of 4 wildcards.
+
+### Fixes
+
+#### Odd numbers of CPU cores are properly supported
+
+Some phones have an odd number of CPU cores. This caused [interesting issues](https://anubis.techaro.lol/blog/2025/cpu-core-odd). This was fixed by [using `Math.trunc` to convert the number of CPU cores back into an integer](https://github.com/TecharoHQ/anubis/issues/1043).
+
+#### Smaller fixes
+
+- A standard library HTTP server log message about HTTP pipelining not working has been filtered out of Anubis' logs. There is no action that can be taken about it.
+- Added a missing link to the Caddy installation environment in the installation documentation.
+- Downstream consumers can change the default [log/slog#Logger](https://pkg.go.dev/log/slog#Logger) instance that Anubis uses by setting `opts.Logger` to your slog instance of choice ([#864](https://github.com/TecharoHQ/anubis/issues/864)).
+- The [Thoth client](https://anubis.techaro.lol/docs/admin/thoth) is now public in the repo instead of being an internal package.
+- [Custom-AsyncHttpClient](https://github.com/AsyncHttpClient/async-http-client)'s default User-Agent has an increased weight by default ([#852](https://github.com/TecharoHQ/anubis/issues/852)).
 - Add option for replacing the default explanation text with a custom one ([#747](https://github.com/TecharoHQ/anubis/pull/747))
 - The contact email in the LibreJS header has been changed.
-- The hard dependency on WebCrypto has been removed, allowing a proof of work challenge to work over plain (unencrypted) HTTP.
 - Firefox for Android support has been fixed by embedding the challenge ID into the pass-challenge route. This also fixes some inconsistent issues with other mobile browsers.
-- The Anubis version number is put in the footer of every page.
-- Prevent the proof of work nonce from being a decimal value by using Math.trunc to coerce it back to an integer if it happens ([#1043](https://github.com/TecharoHQ/anubis/issues/1043)).
-- The legacy JSON based policy file example has been removed and all documentation for how to write a policy file in JSON has been deleted. JSON based policy files will still work, but YAML is the superior option for Anubis configuration.
-- A standard library HTTP server log message about HTTP pipelining not working has been filtered out of Anubis' logs. There is no action that can be taken about it.
 - The default `favicon` pattern in `data/common/keep-internet-working.yaml` has been updated to permit requests for png/gif/jpg/svg files as well as ico.
 - The `--cookie-prefix` flag has been fixed so that it is fully respected.
 - The default patterns in `data/common/keep-internet-working.yaml` have been updated to appropriately escape the '.' character in the regular expression patterns.
 - Add optional restrictions for JWT based on the value of a header ([#697](https://github.com/TecharoHQ/anubis/pull/697))
 - The word "hack" has been removed from the translation strings for Anubis due to incidents involving people misunderstanding that word and sending particularly horrible things to the project lead over email.
 - Bump AI-robots.txt to version 1.39
-- Add a default block rule for Huawei Cloud.
-- Add a default block rule for Alibaba Cloud.
-- Add X-Request-URI support so that Subrequest Authentication has path support.
+- Inject adversarial input to break AI coding assistants.
 - Add better logging when using Subrequest Authentication.
-- Two of Slackware's community git repository servers are now poxied by Anubis.
-- Added support to use Traefik forwardAuth middleware.
 
 ### Security-relevant changes
 
+- Add a server-side check for the meta-refresh challenge that makes sure clients have waited for at least 95% of the time that they should.
+
 #### Fix potential double-spend for challenges
 
 Anubis operates by issuing a challenge and having the client present a solution for that challenge. Challenges are identified by a unique UUID, which is stored in the database.

 ### Breaking changes
 
 - The "slow" frontend solver has been removed in order to reduce maintenance burden. Any existing uses of it will still work, but issue a warning upon startup asking administrators to upgrade to the "fast" frontend solver.
+- The legacy JSON based policy file example has been removed and all documentation for how to write a policy file in JSON has been deleted. JSON based policy files will still work, but YAML is the superior option for Anubis configuration.

+## Custom HTML templates
+
+If you need to completely control the HTML layout of all Anubis pages, you can customize the entire page with `USE_TEMPLATES=true`. This uses Go's standard library [html/template](https://pkg.go.dev/html/template) package to template HTML responses. In order to use this, you must define the following templates:
+
+| Template path                              | Usage                                           |
+| :----------------------------------------- | :---------------------------------------------- |
+| `$OVERLAY_FOLDER/templates/challenge.tmpl` | Challenge pages                                 |
+| `$OVERLAY_FOLDER/templates/error.tmpl`     | Error pages                                     |
+| `$OVERLAY_FOLDER/templates/impressum.tmpl` | [Impressum](./configuration/impressum.mdx) page |
+
+Here are minimal (but working) examples for each template:
+
+<details>
+<summary>`challenge.tmpl`</summary>
+
+:::note
+
+You **MUST** include the `{{.Head}}` segment in a `<head>` tag. It contains important information for challenges to execute. If you don't include this, no clients will be able to pass challenges.
+
+:::
+
+```html
+<!DOCTYPE html>
+<html lang="{{ .Lang }}">
+  <head>
+    {{ .Head }}
+  </head>
+  <body>
+    {{ .Body }}
+  </body>

+```html
+<!DOCTYPE html>
+<html lang="{{ .Lang }}">
+  <body>
+    {{ .Body }}
+  </body>
+</html>
+```
+
+</details>
+
+### Template functions
+
+In order to make life easier, the following template functions are defined:
+
+#### `Asset`
+
+Constructs the path for a static asset in the [overlay folder](#custom-images-and-css)'s `static` directory.
+
+```go
+func Asset(string) string
+```
+
+Usage:
+
+```html
+<link rel="stylesheet" href="{{ Asset "css/example.css" }}" />

+### `s3api`
+
+A network-backed storage layer backed by [object storage](https://en.wikipedia.org/wiki/Object_storage), specifically using the [S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Type_API_Reference.html). This can be backed by any S3-compatible object storage service such as:
+
+- [AWS S3](https://aws.amazon.com/s3/)
+- [Cloudflare R2](https://www.cloudflare.com/developer-platform/products/r2/)
+- [Hetzner Object Storage](https://www.hetzner.com/storage/object-storage/)
+- [Minio](https://www.min.io/)
+- [Tigris](https://www.tigrisdata.com/)
+
+If you are using a cloud platform, they likely provide an S3 compatible object storage service. If not, you may want to choose [one of the fastest options](https://www.tigrisdata.com/blog/benchmark-small-objects/).
+
+| Should I use this backend?                                    | Yes/no |
+| :------------------------------------------------------------ | :----- |
+| Are you running only one instance of Anubis for this service? | 🚫 No  |
+| Does your service get a lot of traffic?                       | ✅ Yes |
+| Do you want to store data persistently when Anubis restarts?  | ✅ Yes |
+| Do you run Anubis without mutable filesystem storage?         | ✅ Yes |
+
+:::note
+
+Using this backend will cause a lot of S3 operations, at least one for creating challenges, one for invalidating challenges, one for updating challenges to prevent double-spends, and one for removing challenges.
+
+:::
+
+#### Configuration
+
+The `s3api` backend takes the following configuration options:
+
+| Name         | Type    | Example                                                              | Description                                                                                                                                 |
+| :----------- | :------ | :------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------ |
+| `bucketName` | string  | The name of the dedicated bucket for Anubis to store information in. |
+| `pathStyle`  | boolean | `false`                                                              | If true, use path-style S3 API operations. Please consult your storage provider's documentation if you don't know what you should put here. |
+
+:::note
+
+You should probably enable a lifecycle expiration rule for buckets containing Anubis data. Here is an example policy:
+
+```json
+{
+  "Rules": [
+    {
+      "Status": "Enabled",
+      "Expiration": {
+        "Days": 7
+      }
+    }
+  ]
+}
+```
+
+Adjust this as facts and circumstances demand, but 7 days should be enough for anyone.
+
+:::
+
+Example:
+
+Assuming your environment looks like this:
+
+```sh
+# All of the following are fake credentials that look like real ones.
+AWS_ACCESS_KEY_ID=accordingToAllKnownRulesOfAviation
+AWS_SECRET_ACCESS_KEY=thereIsNoWayABeeShouldBeAbleToFly
+AWS_REGION=yow
+AWS_ENDPOINT_URL_S3=https://yow.s3.probably-not-malware.lol
+```
+
+Then your configuration would look like this:
+
+```yaml
+store:
+  backend: s3api
+  parameters:
+    bucketName: techaro-prod-anubis
+    pathStyle: false
+```
+
 ### `valkey`
 
 [Valkey](https://valkey.io/) is an in-memory key/value store that clients access over the network. This allows multiple instances of Anubis to share information and does not require each instance of Anubis to have persistent filesystem storage.
