+## 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-burst` is the initial bucket of emails each visitor has. This defaults to 16.
 * `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**.

+## 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 server v1.25.1
+Released June 2, 2022
+
+This release adds the ability to set a log level to facilitate easier debugging of live systems. It also solves a 
+production problem with a few over-users that resulted in Firebase quota problems (only applying to the over-users). 
+We now block visitors from using Firebase if they trigger a quota exceeded response.
+
+On top of that, we updated the Firebase SDK and are now building the release in GitHub Actions. We've also got two
+more translations: Chinese/Simplified and Dutch.
+
+**Features:**
+
+* Advanced logging, with different log levels and hot reloading of the log level ([#284](https://github.com/binwiederhier/ntfy/pull/284))
+* Add `tzdata` to Docker image to allow overriding the timezone with `TZ` ([#307](https://github.com/binwiederhier/ntfy/pull/307), thanks to [@ksurl](https://github.com/ksurl))

+## ntfy iOS app v1.1
+Released May 31, 2022
+
+In this release of the iOS app, we add message priorities (mapped to iOS interruption levels), tags and emojis,
+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).
+
+**Features:**
+
+* [Message priority](https://ntfy.sh/docs/publish/#message-priority) support (no ticket)
+* [Tags/emojis](https://ntfy.sh/docs/publish/#tags-emojis) support (no ticket)
+* [Action buttons](https://ntfy.sh/docs/publish/#action-buttons) support (no ticket)
+* [Click action](https://ntfy.sh/docs/publish/#click-action) support (no ticket)
+* Open topic when notification clicked (no ticket)
+* Notification now makes a sound and vibrates (no ticket)
+* Cancel notifications when navigating to topic (no ticket)
+* iOS 14.0 support (no ticket, [PR#1](https://github.com/binwiederhier/ntfy-ios/pull/1), thanks to [@callum-99](https://github.com/callum-99))
+
+**Bugs:**
+
+* iOS UI not always updating properly ([#267](https://github.com/binwiederhier/ntfy/issues/267))
+
+## 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:**

+
+## 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

+//
+// 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
