+## iOS instant notifications
+Unlike Android, iOS heavily restricts background processing, which sadly makes it impossible to implement instant 
+push notifications without a central server. 
+
+To still support instant notifications on iOS through your self-hosted ntfy server, you have to forward so called `poll_request` 
+messages to the main ntfy.sh server (or any upstream server that's APNS/Firebase connected, if you build your own iOS app),
+which will then forward it to Firebase/APNS.
+
+To configure it, simply set `upstream-base-url` like so:
+
+``` yaml
+upstream-base-url: "https://ntfy.sh"
+```
+
+If set, all incoming messages will publish a poll request to the configured upstream server, containing
+the message ID of the original message, instructing the iOS app to poll this server for the actual message contents.
+
+If `upstream-base-url` is not set, notifications will still eventually get to your device, but delivery can take hours,
+depending on the state of the phone. If you are using your phone, it shouldn't take more than 20-30 minutes though.
+
+In case you're curious, here's an example of the entire flow: 
+
+- In the iOS app, you subscribe to `https://ntfy.example.com/mytopic`
+- The app subscribes to the Firebase topic `6de73be8dfb7d69e...` (the SHA256 of the topic URL)
+- When you publish a message to `https://ntfy.example.com/mytopic`, your ntfy server will publish a 
+  poll request to `https://ntfy.sh/6de73be8dfb7d69e...`. The request from your server to the upstream server 
+  contains only the message ID (in the `X-Poll-ID` header), and the SHA256 checksum of the topic URL (as upstream topic).
+- The ntfy.sh server publishes the poll request message to Firebase, which forwards it to APNS, which forwards it to your iOS device
+- Your iOS device receives the poll request, and fetches the actual message from your server, and then displays it
+
+Here's an example of what the self-hosted server forwards to the upstream server. The request is equivalent to this curl:
+
+```
+curl -X POST -H "X-Poll-ID: s4PdJozxM8na" https://ntfy.sh/6de73be8dfb7d69e32fb2c00c23fe7adbd8b5504406e3068c273aa24cef4055b

 * `visitor-email-limit-replenish` is the rate at which the bucket is refilled (one email per x). Defaults to 1h.
 
+### Firebase limits
+If [Firebase is configured](#firebase-fcm), all messages are also published to a Firebase topic (unless `Firebase: no` 
+is set). Firebase enforces [its own limits](https://firebase.google.com/docs/cloud-messaging/concept-options#topics_throttling)
+on how many messages can be published. Unfortunately these limits are a little vague and can change depending on the time 
+of day. In practice, I have only ever observed `429 Quota exceeded` responses from Firebase if **too many messages are published to 
+the same topic**. 
+
+In ntfy, if Firebase responds with a 429 after publishing to a topic, the visitor (= IP address) who published the message
+is **banned from publishing to Firebase for 10 minutes** (not configurable). Because publishing to Firebase happens asynchronously,
+there is no indication of the user that this has happened. Non-Firebase subscribers (WebSocket or HTTP stream) are not affected.
+After the 10 minutes are up, messages forwarding to Firebase is resumed for this visitor.
+
+If this ever happens, there will be a log message that looks something like this:
+```
+WARN Firebase quota exceeded (likely for topic), temporarily denying Firebase access to visitor
+```

 ## Tuning for scale
 If you're running ntfy for your home server, you probably don't need to worry about scale at all. In its default config,
 if it's not behind a proxy, the ntfy server can keep about **as many connections as the open file limit allows**.

 Depending on *how you run it*, here are a few limits that are relevant:
 
+### WAL for message cache
+By default, the [message cache](#message-cache) (defined by `cache-file`) uses the SQLite default settings, which means it
+syncs to disk on every write. For personal servers, this is perfectly adequate. For larger installations, such as ntfy.sh,
+the [write-ahead log (WAL)](https://sqlite.org/wal.html) should be enabled, and the sync mode should be adjusted. 
+See [this article](https://phiresky.github.io/blog/2020/sqlite-performance-tuning/) for details.
+
+Here's how ntfy.sh has been tuned in the `server.yml` file:

+cache-startup-queries: |
+    pragma journal_mode = WAL;
+    pragma synchronous = normal;
+    pragma temp_store = memory;
+```

 ### For systemd services
 If you're running ntfy in a systemd service (e.g. for .deb/.rpm packages), the main limiting factor is the
 `LimitNOFILE` setting in the systemd unit. The default open files limit for `ntfy.service` is 10,000. You can override it

+## Debugging/tracing
+If something's not working right, you can debug/trace through what the ntfy server is doing by setting the `log-level`
+to `DEBUG` or `TRACE`. The `DEBUG` setting will output information about each published message, but not the message 
+contents. The `TRACE` setting will also print the message contents. 
+
+!!! warning
+    Both options are very verbose and should only be enabled in production for short periods of time. Otherwise, 
+    you're going to run out of disk space pretty quickly.
+
+You can also hot-reload the `log-level` by sending the `SIGHUP` signal to the process after editing the `server.yml` file.
+You can do so by calling `systemctl reload ntfy` (if ntfy is running inside systemd), or by calling `kill -HUP $(pidof ntfy)`. 
+If successful, you'll see something like this:
+
+```
+$ ntfy serve

 # Deprecation notices
 This page is used to list deprecation notices for ntfy. Deprecated commands and options will be 
-**removed after ~3 months** from the time they were deprecated.
+**removed after 1-3 months** from the time they were deprecated. How long the feature is deprecated
+before the behavior is changed depends on the severity of the change, and how prominent the feature is.
 
 ## Active deprecations
 
-### Android app: WebSockets will become the default connection protocol  
-> Active since 2022-03-13, behavior will change in **June 2022**
+### ntfy CLI: `ntfy publish --env-topic` will be removed
+> Active since 2022-06-20, behavior will change end of **July 2022**
 
-In future versions of the Android app, instant delivery connections and connections to self-hosted servers will
-be using the WebSockets protocol. This potentially requires [configuration changes in your proxy](https://ntfy.sh/docs/config/#nginxapache2caddy).
+The `ntfy publish --env-topic` option will be removed. It'll still be possible to specify a topic via the 
+`NTFY_TOPIC` environment variable, but it won't be necessary anymore to specify the `--env-topic` flag.
 
-Due to [reports of varying battery consumption](https://github.com/binwiederhier/ntfy/issues/190) (which entirely 
-seems to depend on the phone), JSON HTTP stream support will not be removed. Instead, I'll just flip the default to 
-WebSocket in June.
+=== "Before"
+    ```
+    $ NTFY_TOPIC=mytopic ntfy publish --env-topic "this is the message"
+    ```
 
-### Android app: Using `since=<timestamp>` instead of `since=<id>`
-> Active since 2022-02-27, behavior will change in **May 2022**
-
-In about 3 months, the Android app will start using `since=<id>` instead of `since=<timestamp>`, which means that it will
-not work with servers older than v1.16.0 anymore. This is to simplify handling of deduplication in the Android app.
-
-The `since=<timestamp>` endpoint will continue to work. This is merely a notice that the Android app behavior will change.
+=== "After"
+    ```
+    $ NTFY_TOPIC=mytopic ntfy publish "this is the message"
+    ```
 
 ## Previous deprecations
 
+### <del>Android app: WebSockets will become the default connection protocol</del>
+> Active since 2022-03-13, behavior will not change (deprecation removed 2022-06-20)
+
+Instant delivery connections and connections to self-hosted servers in the Android app were going to switch
+to use the WebSockets protocol by default. It was decided to keep JSON stream as the most compatible default
+and add a notice banner in the Android app instead.
+
+### Android app: Using `since=<timestamp>` instead of `since=<id>`
+> Active since 2022-02-27, behavior changed with v1.14.0
+
+The Android app started using `since=<id>` instead of `since=<timestamp>`, which means as of Android app v1.14.0, 
+it will not work with servers older than v1.16.0 anymore. This is to simplify handling of deduplication in the Android app.
+
+The `since=<timestamp>` endpoint will continue to work. This is merely a notice that the Android app behavior will change.

 ### Running server via `ntfy` (instead of `ntfy serve`)
 > Deprecated 2021-12-17, behavior changed with v1.10.0

+## Home Assistant
+Here is an example for the configuration.yml file to setup a REST notify component.
+Since Home Assistant is going to POST JSON, you need to specify the root of your ntfy resource.
+
+```yaml
+notify:
+  - name: ntfy
+    platform: rest
+    method: POST_JSON
+    data:
+      topic: YOUR_NTFY_TOPIC
+    title_param_name: title
+    message_param_name: message
+    resource: https://ntfy.sh
+```
+
+If you need to authenticate to your ntfy resource, define the authentication, username and password as below:
+
+```yaml
+notify:
+  - name: ntfy
+    platform: rest
+    method: POST_JSON
+    authentication: basic
+    username: YOUR_USERNAME
+    password: YOUR_PASSWORD

+      topic: YOUR_NTFY_TOPIC
+    title_param_name: title
+    message_param_name: message
+    resource: https://ntfy.sh
+```
+
+If you need to add any other [ntfy specific parameters](https://ntfy.sh/docs/publish/#publish-as-json) such as priority, tags, etc., add them to the `data` array in the example yml. For example:
+
+```yaml
+notify:
+  - name: ntfy
+    platform: rest
+    method: POST_JSON
+    data:
+      topic: YOUR_NTFY_TOPIC
+      priority: 4
+    title_param_name: title
+    message_param_name: message
+    resource: https://ntfy.sh
+```
+
+## Uptime Kuma
+Go to your [Uptime Kuma](https://github.com/louislam/uptime-kuma) Settings > Notifications, click on **Setup Notification**.
+Then set your desired **title** (e.g. "Uptime Kuma"), **ntfy topic**, **Server URL** and **priority (1-5)**:
+
+<div id="uptimekuma-screenshots" class="screenshots">

+    <a href="../static/img/uptimekuma-setup.png"><img src="../static/img/uptimekuma-setup.png"/></a>
+</div>
+
+You can now test the notifications and apply them to monitors:
+
+<div id="uptimekuma-monitor-screenshots" class="screenshots">

+### Matrix Gateway
+The ntfy server implements a [Matrix Push Gateway](https://spec.matrix.org/v1.2/push-gateway-api/) (in combination with
+[UnifiedPush](https://unifiedpush.org) as the [Provider Push Protocol](https://unifiedpush.org/developers/gateway/)). This makes it easier to integrate

+you don't have to set up a separate push proxy (such as [common-proxies](https://github.com/UnifiedPush/common-proxies)).
+
+In short, ntfy accepts Matrix messages on the `/_matrix/push/v1/notify` endpoint (see [Push Gateway API](https://spec.matrix.org/v1.2/push-gateway-api/)), 
+and forwards them to the ntfy topic defined in the `pushkey` of the message. The message will then be forwarded to the

+## ntfy iOS app v1.1
+Released May 31, 2022

+action buttons to open websites or perform HTTP requests (in the notification and the detail view), a custom click
+action when the notification is tapped, and various other fixes.
+
+It also adds support for self-hosted servers (albeit not supporting auth yet). The self-hosted server needs to be
+configured to forward poll requests to upstream ntfy.sh for push notifications to work (see [iOS push notifications](https://ntfy.sh/docs/config/#ios-instant-notifications)
+for details).

+## ntfy server v1.24.0
+Released May 28, 2022
+
+This release of the ntfy server brings supporting features for the ntfy iOS app. Most importantly, it
+enables support for self-hosted servers in combination with the iOS app. This is to overcome the restrictive
+Apple development environment.
+
+**Features:**
+
+* Regularly send Firebase keepalive messages to ~poll topic to support self-hosted servers (no ticket)
+* Add subscribe filter to query exact messages by ID (no ticket)
+* Support for `poll_request` messages to support [iOS push notifications](https://ntfy.sh/docs/config/#ios-instant-notifications) for self-hosted servers (no ticket)
+
+**Bugs:**
+
+* Support emails without `Content-Type` ([#265](https://github.com/binwiederhier/ntfy/issues/265), thanks to [@dmbonsall](https://github.com/dmbonsall))
+
+**Additional translations:**
+
+* Italian (thanks to [@Genio2003](https://hosted.weblate.org/user/Genio2003/))
+
+## ntfy iOS app v1.0
+Released May 25, 2022
+
+This is the first version of the ntfy iOS app. It supports only ntfy.sh (no selfhosted servers) and only messages + title
+(no priority, tags, attachments, ...). I'll rapidly add (hopefully) most of the other ntfy features, and then I'll focus
+on self-hosted servers.
+
+The app is now available in the [App Store](https://apps.apple.com/us/app/ntfy/id1625396347).
+
+**Tickets:**
+
+* iOS app ([#4](https://github.com/binwiederhier/ntfy/issues/4), see also: [TestFlight summary](https://github.com/binwiederhier/ntfy/issues/4#issuecomment-1133767150))
+
+**Thanks:**
+
+* Thank you to all the testers who tried out the app. You guys gave me the confidence that it's ready to release (albeit with
+  some known issues which will be addressed in follow-up releases).

 ## ntfy server v1.23.0
 Released May 21, 2022
 
+This release ships a CLI for Windows and macOS, as well as the ability to disable the web app entirely. On top of that, 
+it adds support for APNs, the iOS messaging service. This is needed for the (soon to be released) iOS app.
+
 **Features:**
 
 * [Windows](https://ntfy.sh/docs/install/#windows) and [macOS](https://ntfy.sh/docs/install/#macos) builds for the [ntfy CLI](https://ntfy.sh/docs/subscribe/cli/) ([#112](https://github.com/binwiederhier/ntfy/issues/112))

+//   - On iOS, we are not allowed to receive data-only messages, so we build messages with an "alert" (with title and

+//     message in the Notification Service Extension.
+//
+// Keepalive messages ("keepalive"):
+//   - On Android, we subscribe to the "~control" topic, which is used to restart the foreground service (if it died,
+//     e.g. after an app update). We send these keepalive messages regularly (see Config.FirebaseKeepaliveInterval).
+//   - On iOS, we subscribe to the "~poll" topic, which is used to poll all topics regularly. This is because iOS
+//     does not allow any background or scheduled activity at all.
+//
+// Poll request messages ("poll_request"):
+//   - Normal messages are turned into poll request messages if anonymous users are not allowed to read the message.
+//     On Android, this will trigger the app to poll the topic and thereby displaying new messages.
+//   - If UpstreamBaseURL is set, messages are forwarded as poll requests to an upstream server and then forwarded
+//     to Firebase here. This is mainly for iOS to support self-hosted servers.

+// In the picture below, ntfy is the Push Gateway (mostly in this file), as well as the Push Provider (ntfy's
