Bugfixes
--------

- Fix a long-standing bug where a device list update might not be sent to clients in certain circumstances. ([\#14435](https://github.com/matrix-org/synapse/issues/14435), [\#14592](https://github.com/matrix-org/synapse/issues/14592), [\#14604](https://github.com/matrix-org/synapse/issues/14604))
- Suppress a spurious warning when `POST /rooms/<room_id>/<membership>/`, `POST /join/<room_id_or_alias`, or the unspecced `PUT /join/<room_id_or_alias>/<txn_id>` receive an empty HTTP request body. ([\#14600](https://github.com/matrix-org/synapse/issues/14600))
- Return spec-compliant JSON errors when unknown endpoints are requested. ([\#14620](https://github.com/matrix-org/synapse/issues/14620), [\#14621](https://github.com/matrix-org/synapse/issues/14621))
- Update html templates to load images over HTTPS. Contributed by @ashfame. ([\#14625](https://github.com/matrix-org/synapse/issues/14625))
- Fix a long-standing bug where the user directory would return 1 more row than requested. ([\#14631](https://github.com/matrix-org/synapse/issues/14631))
- Reject invalid read receipt requests with empty room or event IDs. Contributed by Nick @ Beeper (@fizzadar). ([\#14632](https://github.com/matrix-org/synapse/issues/14632))
- Fix a bug introduced in Synapse 1.67.0 where not specifying a config file or a server URL would lead to the `register_new_matrix_user` script failing. ([\#14637](https://github.com/matrix-org/synapse/issues/14637))
- Fix a long-standing bug where the user directory and room/user stats might be out of sync. ([\#14639](https://github.com/matrix-org/synapse/issues/14639), [\#14643](https://github.com/matrix-org/synapse/issues/14643))
- Fix a bug introduced in Synapse 1.72.0 where the background updates to add non-thread unique indexes on receipts would fail if they were previously interrupted. ([\#14650](https://github.com/matrix-org/synapse/issues/14650))
- Improve validation of field size limits in events. ([\#14664](https://github.com/matrix-org/synapse/issues/14664))
- Fix bugs introduced in Synapse 1.55.0 and 1.69.0 where application services would not be notified of events in the correct rooms, due to stale caches. ([\#14670](https://github.com/matrix-org/synapse/issues/14670))

Improved Documentation
----------------------

- Update worker settings for `pusher` and `federation_sender` functionality. ([\#14493](https://github.com/matrix-org/synapse/issues/14493))
- Add links to third party package repositories, and point to the bug which highlights Ubuntu's out-of-date packages. ([\#14517](https://github.com/matrix-org/synapse/issues/14517))
- Remove old, incorrect minimum postgres version note and replace with a link to the [Dependency Deprecation Policy](https://matrix-org.github.io/synapse/v1.73/deprecation_policy.html). ([\#14590](https://github.com/matrix-org/synapse/issues/14590))
- Add Single-Sign On setup instructions for Mastodon-based instances. ([\#14594](https://github.com/matrix-org/synapse/issues/14594))
- Change `turn_allow_guests` example value to lowercase `true`. ([\#14634](https://github.com/matrix-org/synapse/issues/14634))

Internal Changes
----------------

- Optimise push badge count calculations. Contributed by Nick @ Beeper (@fizzadar). ([\#14255](https://github.com/matrix-org/synapse/issues/14255))
- Faster remote room joins: stream the un-partial-stating of rooms over replication. ([\#14473](https://github.com/matrix-org/synapse/issues/14473), [\#14474](https://github.com/matrix-org/synapse/issues/14474))
- Share the `ClientRestResource` for both workers and the main process. ([\#14528](https://github.com/matrix-org/synapse/issues/14528))
- Add `--editable` flag to `complement.sh` which uses an editable install of Synapse for faster turn-around times whilst developing iteratively. ([\#14548](https://github.com/matrix-org/synapse/issues/14548))
- Faster joins: use servers list approximation to send read receipts when in partial state instead of waiting for the full state of the room. ([\#14549](https://github.com/matrix-org/synapse/issues/14549))
- Modernize unit tests configuration related to workers. ([\#14568](https://github.com/matrix-org/synapse/issues/14568))

+Synapse 1.71.0 (2022-11-08)
+===========================
+
+Please note that, as announced in the release notes for Synapse 1.69.0, legacy Prometheus metric names are now disabled by default.
+They will be removed altogether in Synapse 1.73.0.
+If not already done, server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
+See the [upgrade notes](https://matrix-org.github.io/synapse/v1.71/upgrade.html#upgrading-to-v1710) for more details.
+
+**Note:** in line with our [deprecation policy](https://matrix-org.github.io/synapse/latest/deprecation_policy.html) for platform dependencies, this will be the last release to support PostgreSQL 10, which reaches upstream end-of-life on November 10th, 2022. Future releases of Synapse will require PostgreSQL 11+.
+
+No significant changes since 1.71.0rc2.

+### Mastodon
+
+[Mastodon](https://docs.joinmastodon.org/) instances provide an [OAuth API](https://docs.joinmastodon.org/spec/oauth/), allowing those instances to be used as a single sign-on provider for Synapse.
+
+The first step is to register Synapse as an application with your Mastodon instance, using the [Create an application API](https://docs.joinmastodon.org/methods/apps/#create) (see also [here](https://docs.joinmastodon.org/client/token/)). There are several ways to do this, but in the example below we are using CURL.
+
+This example assumes that:
+* the Mastodon instance website URL is `https://your.mastodon.instance.url`, and
+* Synapse will be registered as an app named `my_synapse_app`.
+
+Send the following request, substituting the value of `synapse_public_baseurl` from your Synapse installation.
+```sh
+curl -d "client_name=my_synapse_app&redirect_uris=https://[synapse_public_baseurl]/_synapse/client/oidc/callback" -X POST https://your.mastodon.instance.url/api/v1/apps
+```
+
+You should receive a response similar to the following. Make sure to save it.
+```json
+{"client_id":"someclientid_123","client_secret":"someclientsecret_123","id":"12345","name":"my_synapse_app","redirect_uri":"https://[synapse_public_baseurl]/_synapse/client/oidc/callback","website":null,"vapid_key":"somerandomvapidkey_123"}
+```
+
+As the Synapse login mechanism needs an attribute to uniquely identify users, and Mastodon's endpoint does not return a `sub` property, an alternative `subject_claim` has to be set. Your Synapse configuration should include the following:
+
+```yaml
+oidc_providers:
+  - idp_id: my_mastodon
+    idp_name: "Mastodon Instance Example"
+    discover: false
+    issuer: "https://your.mastodon.instance.url/@admin"
+    client_id: "someclientid_123"    
+    client_secret: "someclientsecret_123"
+    authorization_endpoint: "https://your.mastodon.instance.url/oauth/authorize"
+    token_endpoint: "https://your.mastodon.instance.url/oauth/token"
+    userinfo_endpoint: "https://your.mastodon.instance.url/api/v1/accounts/verify_credentials"
+    scopes: ["read"]
+    user_mapping_provider:
+      config:
+        subject_claim: "id"
+```
+
+Note that the fields `client_id` and `client_secret` are taken from the CURL response above.

+# coturn TURN server
+
+The following sections describe how to install [coturn](<https://github.com/coturn/coturn>) (which implements the TURN REST API).
+
+## `coturn` setup
+
+### Initial installation
+
+The TURN daemon `coturn` is available from a variety of sources such as native package managers, or installation from source.
+
+#### Debian and Ubuntu based distributions
+
+Just install the debian package:
+
+```sh
+sudo apt install coturn
+```
+
+This will install and start a systemd service called `coturn`.
+
+#### Source installation
+
+1. Download the [latest release](https://github.com/coturn/coturn/releases/latest) from github.  Unpack it and `cd` into the directory.
+
+1.  Configure it:
+
+    ```sh
+    ./configure
+    ```
+
+    You may need to install `libevent2`: if so, you should do so in
+    the way recommended by your operating system. You can ignore
+    warnings about lack of database support: a database is unnecessary
+    for this purpose.
+
+1.  Build and install it:
+
+    ```sh
+    make
+    sudo make install
+    ```
+
+### Configuration
+
+1.  Create or edit the config file in `/etc/turnserver.conf`. The relevant
+    lines, with example values, are:
+
+    ```
+    use-auth-secret
+    static-auth-secret=[your secret key here]
+    realm=turn.myserver.org
+    ```
+
+    See `turnserver.conf` for explanations of the options. One way to generate
+    the `static-auth-secret` is with `pwgen`:
+
+    ```sh
+    pwgen -s 64 1
+    ```
+
+    A `realm` must be specified, but its value is somewhat arbitrary. (It is
+    sent to clients as part of the authentication flow.) It is conventional to
+    set it to be your server name.
+
+1.  You will most likely want to configure `coturn` to write logs somewhere. The
+    easiest way is normally to send them to the syslog:
+
+    ```sh
+    syslog
+    ```
+
+    (in which case, the logs will be available via `journalctl -u coturn` on a
+    systemd system). Alternatively, `coturn` can be configured to write to a
+    logfile - check the example config file supplied with `coturn`.
+
+1.  Consider your security settings. TURN lets users request a relay which will
+    connect to arbitrary IP addresses and ports. The following configuration is
+    suggested as a minimum starting point:
+
+    ```
+    # VoIP traffic is all UDP. There is no reason to let users connect to arbitrary TCP endpoints via the relay.
+    no-tcp-relay
+
+    # don't let the relay ever try to connect to private IP address ranges within your network (if any)
+    # given the turn server is likely behind your firewall, remember to include any privileged public IPs too.

+# eturnal TURN server
+
+The following sections describe how to install [eturnal](<https://github.com/processone/eturnal>) 
+(which implements the TURN REST API).
+
+## `eturnal` setup
+
+### Initial installation
+
+The `eturnal` TURN server implementation is available from a variety of sources 
+such as native package managers, binary packages, installation from source or 
+[container image](https://eturnal.net/documentation/code/docker.html). They are 
+all described [here](https://github.com/processone/eturnal#installation).
+
+Quick-Test instructions in a [Linux Shell](https://github.com/processone/eturnal/blob/master/QUICK-TEST.md) 
+or with [Docker](https://github.com/processone/eturnal/blob/master/docker-k8s/QUICK-TEST.md) 
+are available as well.
+
+### Configuration
+
+After installation, `eturnal` usually ships a [default configuration file](https://github.com/processone/eturnal/blob/master/config/eturnal.yml) 
+here: `/etc/eturnal.yml` (and, if not found there, there is a backup file here: 
+`/opt/eturnal/etc/eturnal.yml`). It uses the (indentation-sensitive!) [YAML](https://en.wikipedia.org/wiki/YAML) 
+format. The file contains further explanations.
+
+Here are some hints how to configure eturnal on your [host machine](https://github.com/processone/eturnal#configuration) 
+or when using e.g. [Docker](https://eturnal.net/documentation/code/docker.html).
+You may also further deep dive into the [reference documentation](https://eturnal.net/documentation/).
+
+`eturnal` runs out of the box with the default configuration. To enable TURN and 
+to integrate it with your homeserver, some aspects in `eturnal`'s default configuration file 
+must be edited:
+
+1.  Homeserver's [`turn_shared_secret`](../../usage/configuration/config_documentation.md#turn_shared_secret) 
+    and eturnal's shared `secret` for authentication
+
+    Both need to have the same value. Uncomment and adjust this line in `eturnal`'s 
+    configuration file:
+
+    ```yaml
+    secret: "long-and-cryptic"     # Shared secret, CHANGE THIS.
+    ```
+
+    One way to generate a `secret` is with `pwgen`:
+
+    ```sh
+    pwgen -s 64 1
+    ```
+
+1.  Public IP address
+
+    If your TURN server is behind NAT, the NAT gateway must have an external,
+    publicly-reachable IP address. `eturnal` tries to autodetect the public IP address, 
+    however, it may also be configured by uncommenting and adjusting this line, so 
+    `eturnal` advertises that address to connecting clients:
+
+    ```yaml
+    relay_ipv4_addr: "203.0.113.4" # The server's public IPv4 address.
+    ```
+
+    If your NAT gateway is reachable over both IPv4 and IPv6, you may
+    configure `eturnal` to advertise each available address:
+
+    ```yaml
+    relay_ipv4_addr: "203.0.113.4" # The server's public IPv4 address.
+    relay_ipv6_addr: "2001:db8::4" # The server's public IPv6 address (optional).
+    ```
+
+    When advertising an external IPv6 address, ensure that the firewall and
+    network settings of the system running your TURN server are configured to
+    accept IPv6 traffic, and that the TURN server is listening on the local
+    IPv6 address that is mapped by NAT to the external IPv6 address.
+
+1.  Logging
+
+    If `eturnal` was started by systemd, log files are written into the
+    `/var/log/eturnal` directory by default. In order to log to the [journal](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html)
+    instead, the `log_dir` option can be set to `stdout` in the configuration file.
+
+1.  Security considerations
+
+    Consider your security settings. TURN lets users request a relay which will
+    connect to arbitrary IP addresses and ports. The following configuration is
+    suggested as a minimum starting point, [see also the official documentation](https://eturnal.net/documentation/#blacklist):
+
+    ```yaml
+    ## Reject TURN relaying from/to the following addresses/networks:
+    blacklist:                 # This is the default blacklist.
+        - "127.0.0.0/8"        # IPv4 loopback.
+        - "::1"                # IPv6 loopback.
+        - recommended          # Expands to a number of networks recommended to be
+                               # blocked, but includes private networks. Those
+                               # would have to be 'whitelist'ed if eturnal serves
+                               # local clients/peers within such networks.
+    ```
+
+    To whitelist IP addresses or specific (private) networks, you need to **add** a 
+    whitelist part into the configuration file, e.g.:
+
+    ```yaml
+    whitelist:
+        - "192.168.0.0/16"
+        - "203.0.113.113"
+        - "2001:db8::/64"
+    ```
+
+    The more specific, the better.
+
+1.  TURNS (TURN via TLS/DTLS)
+
+    Also consider supporting TLS/DTLS. To do this, adjust the following settings
+    in the `eturnal.yml` configuration file (TLS parts should not be commented anymore):
+
+    ```yaml
+    listen:
+        - ip: "::"
+          port: 3478
+          transport: udp
+        - ip: "::"
+          port: 3478
+          transport: tcp
+        - ip: "::"
+          port: 5349
+          transport: tls
+
+    ## TLS certificate/key files (must be readable by 'eturnal' user!):
+    tls_crt_file: /etc/eturnal/tls/crt.pem
+    tls_key_file: /etc/eturnal/tls/key.pem
+    ```
+
+    In this case, replace the `turn:` schemes in homeserver's `turn_uris` settings
+    with `turns:`. More is described [here](../../usage/configuration/config_documentation.md#turn_uris).
+
+    We recommend that you only try to set up TLS/DTLS once you have set up a
+    basic installation and got it working.
+
+    NB: If your TLS certificate was provided by Let's Encrypt, TLS/DTLS will
+    not work with any Matrix client that uses Chromium's WebRTC library. This
+    currently includes Element Android & iOS; for more details, see their
+    [respective](https://github.com/vector-im/element-android/issues/1533)
+    [issues](https://github.com/vector-im/element-ios/issues/2712) as well as the underlying
+    [WebRTC issue](https://bugs.chromium.org/p/webrtc/issues/detail?id=11710).
+    Consider using a ZeroSSL certificate for your TURN server as a working alternative.
+
+1.  Firewall
+
+    Ensure your firewall allows traffic into the TURN server on the ports
+    you've configured it to listen on (By default: 3478 and 5349 for TURN
+    traffic (remember to allow both TCP and UDP traffic), and ports 49152-65535
+    for the UDP relay.)
+
+1.  Reload/ restarting `eturnal`
+
+    Changes in the configuration file require `eturnal` to reload/ restart, this
+    can be achieved by:
+
+    ```sh
+    eturnalctl reload
+    ```
+    
+    `eturnal` performs a configuration check before actually reloading/ restarting
+    and provides hints, if something is not correctly configured.
+
+### eturnalctl opterations script
+
+`eturnal` offers a handy [operations script](https://eturnal.net/documentation/#Operation) 
+which can be called e.g. to check, whether the service is up, to restart the service, 
+to query how many active sessions exist, to change logging behaviour and so on.
+
+Hint: If `eturnalctl` is not part of your `$PATH`, consider either sym-linking it (e.g. ´ln -s /opt/eturnal/bin/eturnalctl /usr/local/bin/eturnalctl´) or call it from the default `eturnal` directory directly: e.g. `/opt/eturnal/bin/eturnalctl info`

+For TURN relaying to work, the TURN service must be hosted on a server/endpoint with a public IP.
 
 Hosting TURN behind NAT requires port forwaring and for the NAT gateway to have a public IP.
 However, even with appropriate configuration, NAT is known to cause issues and to often not work.
 
-## `coturn` setup
-
-### Initial installation
-
-The TURN daemon `coturn` is available from a variety of sources such as native package managers, or installation from source.
-
-#### Debian installation
-
-Just install the debian package:
-
-```sh
-apt install coturn
-```
-
-This will install and start a systemd service called `coturn`.
-
-#### Source installation
-
-1. Download the [latest release](https://github.com/coturn/coturn/releases/latest) from github.  Unpack it and `cd` into the directory.
-
-1.  Configure it:
-
-    ```sh
-    ./configure
-    ```
-
-    You may need to install `libevent2`: if so, you should do so in
-    the way recommended by your operating system. You can ignore
-    warnings about lack of database support: a database is unnecessary
-    for this purpose.
-
-1.  Build and install it:
-
-    ```sh
-    make
-    make install
-    ```
-
-### Configuration
-
-1.  Create or edit the config file in `/etc/turnserver.conf`. The relevant
-    lines, with example values, are:
-
-    ```
-    use-auth-secret
-    static-auth-secret=[your secret key here]
-    realm=turn.myserver.org
-    ```
-
-    See `turnserver.conf` for explanations of the options. One way to generate
-    the `static-auth-secret` is with `pwgen`:
-
-    ```sh
-    pwgen -s 64 1
-    ```
-
-    A `realm` must be specified, but its value is somewhat arbitrary. (It is
-    sent to clients as part of the authentication flow.) It is conventional to
-    set it to be your server name.
-
-1.  You will most likely want to configure coturn to write logs somewhere. The
-    easiest way is normally to send them to the syslog:
-
-    ```sh
-    syslog
-    ```
-
-    (in which case, the logs will be available via `journalctl -u coturn` on a
-    systemd system). Alternatively, coturn can be configured to write to a
-    logfile - check the example config file supplied with coturn.
-
-1.  Consider your security settings. TURN lets users request a relay which will
-    connect to arbitrary IP addresses and ports. The following configuration is
-    suggested as a minimum starting point:
-
-    ```
-    # VoIP traffic is all UDP. There is no reason to let users connect to arbitrary TCP endpoints via the relay.
-    no-tcp-relay
-
-    # don't let the relay ever try to connect to private IP address ranges within your network (if any)
-    # given the turn server is likely behind your firewall, remember to include any privileged public IPs too.

-    network settings of the system running your TURN server are configured to
-    accept IPv6 traffic, and that the TURN server is listening on the local
-    IPv6 address that is mapped by NAT to the external IPv6 address.

-      ```
-
-    * If you installed from source:
-
-      ```sh
-      bin/turnserver -o
-      ```
+Afterwards, the homeserver needs some further configuration.
 
 ## Synapse setup
 
 Your homeserver configuration file needs the following extra keys:
 
-1.  "`turn_uris`": This needs to be a yaml list of public-facing URIs
-    for your TURN server to be given out to your clients. Add separate
-    entries for each transport your TURN server supports.
-2.  "`turn_shared_secret`": This is the secret shared between your
-    homeserver and your TURN server, so you should set it to the same
-    string you used in turnserver.conf.
-3.  "`turn_user_lifetime`": This is the amount of time credentials
-    generated by your homeserver are valid for (in milliseconds).
-    Shorter times offer less potential for abuse at the expense of
-    increased traffic between web clients and your homeserver to
-    refresh credentials. The TURN REST API specification recommends
-    one day (86400000).
-4.  "`turn_allow_guests`": Whether to allow guest users to use the
-    TURN server. This is enabled by default, as otherwise VoIP will
-    not work reliably for guests. However, it does introduce a
-    security risk as it lets guests connect to arbitrary endpoints
-    without having gone through a CAPTCHA or similar to register a
-    real account.

+# Upgrading to v1.73.0
+
+## Legacy Prometheus metric names have now been removed
+
+Synapse v1.69.0 included the deprecation of legacy Prometheus metric names
+and offered an option to disable them.
+Synapse v1.71.0 disabled legacy Prometheus metric names by default.
+
+This version, v1.73.0, removes those legacy Prometheus metric names entirely.
+This also means that the `enable_legacy_metrics` configuration option has been
+removed; it will no longer be possible to re-enable the legacy metric names.
+
+If you use metrics and have not yet updated your Grafana dashboard(s),
+Prometheus console(s) or alerting rule(s), please consider doing so when upgrading
+to this version.
+Note that the included Grafana dashboard was updated in v1.72.0 to correct some
+metric names which were missed when legacy metrics were disabled by default.
+
+See [v1.69.0: Deprecation of legacy Prometheus metric names](#deprecation-of-legacy-prometheus-metric-names)
+for more context.
+
+
+# Upgrading to v1.72.0
+
+## Dropping support for PostgreSQL 10
+
+In line with our [deprecation policy](deprecation_policy.md), we've dropped
+support for PostgreSQL 10, as it is no longer supported upstream.
+
+This release of Synapse requires PostgreSQL 11+.
+
+
+# Upgrading to v1.71.0
+
+## Removal of the `generate_short_term_login_token` module API method
+
+As announced with the release of [Synapse 1.69.0](#deprecation-of-the-generate_short_term_login_token-module-api-method), the deprecated `generate_short_term_login_token` module method has been removed.
+
+Modules relying on it can instead use the `create_login_token` method.
+
+
+## Changes to the events received by application services (interest)
+
+To align with spec (changed in
+[MSC3905](https://github.com/matrix-org/matrix-spec-proposals/pull/3905)), Synapse now
+only considers local users to be interesting. In other words, the `users` namespace
+regex is only be applied against local users of the homeserver.
+
+Please note, this probably doesn't affect the expected behavior of your application
+service, since an interesting local user in a room still means all messages in the room
+(from local or remote users) will still be considered interesting. And matching a room
+with the `rooms` or `aliases` namespace regex will still consider all events sent in the
+room to be interesting to the application service.
+
+If one of your application service's `users` regex was intending to match a remote user,
+this will no longer match as you expect. The behavioral mismatch between matching all
+local users and some remote users is why the spec was changed/clarified and this
+caveat is no longer supported.
+
+
+## Legacy Prometheus metric names are now disabled by default
+
+Synapse v1.71.0 disables legacy Prometheus metric names by default.
+For administrators that still rely on them and have not yet had chance to update their
+uses of the metrics, it's still possible to specify `enable_legacy_metrics: true` in
+the configuration to re-enable them temporarily.
+
+Synapse v1.73.0 will **remove legacy metric names altogether** and at that point,
+it will no longer be possible to re-enable them.
+
+If you do not use metrics or you have already updated your Grafana dashboard(s),
+Prometheus console(s) and alerting rule(s), there is no action needed.
+
+See [v1.69.0: Deprecation of legacy Prometheus metric names](#deprecation-of-legacy-prometheus-metric-names).
