+
+* [#764](https://github.com/shlinkio/shlink/issues/764) Fixed error when trying to match an existing short URL which does not have `validSince` and/or `validUntil`, but you are providing either one of them for the new one.
+
+
+## 2.2.0 - 2020-05-09
+
+#### Added
+
+* [#712](https://github.com/shlinkio/shlink/issues/712) Added support to integrate Shlink with a [mercure hub](https://mercure.rocks/) server.
+
+    Thanks to that, Shlink will be able to publish events that can be consumed in real time.
+
+    For now, two topics (events) are published, when new visits occur. Both include a payload with the visit and the shortUrl:
+
+        * A visit occurs on any short URL: `https://shlink.io/new-visit`.
+        * A visit occurs on short URLs with a specific short code: `https://shlink.io/new-visit/{shortCode}`.
+
+    The updates are only published when serving Shlink with swoole.
+
+    Also, Shlink exposes a new endpoint `GET /rest/v2/mercure-info`, which returns the public URL of the mercure hub, and a valid JWT that can be used to subscribe to updates.
+
+* [#673](https://github.com/shlinkio/shlink/issues/673) Added new `[GET /visits]` rest endpoint which returns basic visits stats.
+* [#674](https://github.com/shlinkio/shlink/issues/674) Added new `[GET /tags/{tag}/visits]` rest endpoint which returns visits by tag.
+
+    It works in the same way as the `[GET /short-urls/{shortCode}/visits]` one, returning the same response payload, and supporting the same query params, but the response is the list of visits in all short URLs which have provided tag.
+
+* [#672](https://github.com/shlinkio/shlink/issues/672) Enhanced `[GET /tags]` rest endpoint so that it is possible to get basic stats info for every tag.
+
+    Now, if the `withStats=true` query param is provided, the response payload will include a new `stats` property which is a list with the amount of short URLs and visits for every tag.
+
+    Also, the `tag:list` CLI command has been changed and it always behaves like this.
+
+* [#640](https://github.com/shlinkio/shlink/issues/640) Allowed to optionally disable visitors' IP address anonymization. This will make Shlink no longer be GDPR-compliant, but it's OK if you only plan to share your URLs in countries without this regulation.
+
+#### Changed
+
+* [#692](https://github.com/shlinkio/shlink/issues/692) Drastically improved performance when loading visits. Specially noticeable when loading big result sets.
+* [#657](https://github.com/shlinkio/shlink/issues/657) Updated how DB tests are run in travis by using docker containers which allow all engines to be covered.
+* [#751](https://github.com/shlinkio/shlink/issues/751) Updated PHP and swoole versions used in docker image, and removed mssql-tools, as they are not needed.

+* [#677](https://github.com/shlinkio/shlink/issues/677) Fixed `/health` endpoint returning `503` fail responses when the database connection has expired.
+* [#732](https://github.com/shlinkio/shlink/issues/732) Fixed wrong client IP in access logs when serving app with swoole behind load balancer.

+* [#641](https://github.com/shlinkio/shlink/issues/641) Added two new flags to the `visit:locate` command, `--retry` and `--all`.
+

+    * When `--all` is provided together with `--retry`, it will try to re-locate all existing visits. A warning and confirmation are displayed, as this can have side effects.

+
+
+## 1.21.0 - 2019-12-29
+
+#### Added
+
+* [#118](https://github.com/shlinkio/shlink/issues/118) API errors now implement the [problem details](https://tools.ietf.org/html/rfc7807) standard.
+
+    In order to make it backwards compatible, two things have been done:
+
+    * Both the old `error` and `message` properties have been kept on error response, containing the same values as the `type` and `detail` properties respectively.
+    * The API `v2` has been enabled. If an error occurs when calling the API with this version, the `error` and `message` properties will not be returned.
+
+    > After Shlink v2 is released, both API versions will behave like API v2.
+
+* [#575](https://github.com/shlinkio/shlink/issues/575) Added support to filter short URL lists by date ranges.
+
+    * The `GET /short-urls` endpoint now accepts the `startDate` and `endDate` query params.
+    * The `short-urls:list` command now allows `--startDate` and `--endDate` flags to be optionally provided.
+
+* [#338](https://github.com/shlinkio/shlink/issues/338) Added support to asynchronously notify external services via webhook, only when shlink is served with swoole.
+
+    Configured webhooks will receive a POST request every time a URL receives a visit, including information about the short URL and the visit.
+
+    The payload will look like this:
+
+    ```json
+    {
+      "shortUrl": {},
+      "visit": {}
+    }
+    ```
+
+    > The `shortUrl` and `visit` props have the same shape as it is defined in the [API spec](https://api-spec.shlink.io).
+
+#### Changed
+
+* [#492](https://github.com/shlinkio/shlink/issues/492) Updated to monolog 2, together with other dependencies, like Symfony 5 and infection-php.
+* [#527](https://github.com/shlinkio/shlink/issues/527) Increased minimum required mutation score for unit tests to 80%.
+* [#557](https://github.com/shlinkio/shlink/issues/557) Added a few php.ini configs for development and production docker images.

+#### Added
+
+* [#519](https://github.com/shlinkio/shlink/issues/519) Documented how to customize web workers and task workers for the docker image.
+
+#### Changed
+
+* *Nothing*
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#512](https://github.com/shlinkio/shlink/issues/512) Fixed query params not being properly forwarded from short URL to long one.
+* [#540](https://github.com/shlinkio/shlink/issues/540) Fixed errors thrown when creating short URLs if the original URL has an internationalized domain name and URL validation is enabled.
+* [#528](https://github.com/shlinkio/shlink/issues/528) Ensured `db:create` and `db:migrate` commands do not silently fail when run as part of `install` or `update`.
+* [#518](https://github.com/shlinkio/shlink/issues/518) Fixed service which updates Geolite db file to use a local lock instead of a shared one, since every shlink instance holds its own db instance.
+
+
+## 1.20.0 - 2019-11-02
+
+#### Added
+
+* [#491](https://github.com/shlinkio/shlink/issues/491) Added improved short code generation logic.
+
+    Now, short codes are truly random, which removes the guessability factor existing in previous versions.
+
+    Generated short codes have 5 characters, and shlink makes sure they keep unique, while making it backwards-compatible.
+
+* [#418](https://github.com/shlinkio/shlink/issues/418) and [#419](https://github.com/shlinkio/shlink/issues/419) Added support to redirect any 404 error to a custom URL.
+
+    It was already possible to configure this but only for invalid short URLs. Shlink now also support configuring redirects for the base URL and any other kind of "not found" error.
+
+    The three URLs can be different, and it is already possible to pass them to the docker image via configuration or env vars.
+
+    The installer also asks for these two new configuration options.
+
+* [#497](https://github.com/shlinkio/shlink/issues/497) Officially added support for MariaDB.
+
+#### Changed
+
+* [#458](https://github.com/shlinkio/shlink/issues/458) Updated coding styles to use [shlinkio/php-coding-standard](https://github.com/shlinkio/php-coding-standard) v2.0.0.
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#507](https://github.com/shlinkio/shlink/issues/507) Fixed error with too long original URLs by increasing size to the maximum value (2048) based on [the standard](https://stackoverflow.com/a/417184).
+* [#502](https://github.com/shlinkio/shlink/issues/502) Fixed error when providing the port as part of the domain on short URLs.
+* [#509](https://github.com/shlinkio/shlink/issues/509) Fixed error when trying to generate a QR code for a short URL which uses a custom domain.
+* [#522](https://github.com/shlinkio/shlink/issues/522) Highly mitigated errors thrown when lots of short URLs are created concurrently including new and existing tags.

+
+* If you are going to use MySQL, MariaDB, PostgreSQL or Microsoft SQL Server, create an empty database with the name of your choice.
 * Recursively grant write permissions to the `data` directory. Shlink uses it to cache some information.
 * Setup the application by running the `bin/install` script. It is a command line tool that will guide you through the installation process. **Take into account that this tool has to be run directly on the server where you plan to host Shlink. Do not run it before uploading/moving it there.**
-* Expose shlink to the web, either by using a traditional web server + fast CGI approach, or by using a [swoole](https://www.swoole.co.uk/) non-blocking server.
-
-    * **Using a web server:**
-
-        For example, assuming your domain is doma.in and shlink is in the `/path/to/shlink` folder, these would be the basic configurations for Nginx and Apache.
-
-        *Nginx:*
-
-        ```nginx
-        server {
-            server_name doma.in;
-            listen 80;
-            root /path/to/shlink/public;
-            index index.php;
-            charset utf-8;
-
-            location / {
-                try_files $uri $uri/ /index.php$is_args$args;
-            }
-
-            location ~ \.php$ {
-                fastcgi_split_path_info ^(.+\.php)(/.+)$;
-                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
-                fastcgi_index index.php;
-                include fastcgi.conf;
-            }
-
-            location ~ /\.ht {
-                deny all;
-            }
-        }
-        ```
-
-        *Apache:*
-
-        ```apache
-        <VirtualHost *:80>
-            ServerName doma.in
-            DocumentRoot "/path/to/shlink/public"
-
-            <Directory "/path/to/shlink/public">

-                Allow from all
-            </Directory>
-        </VirtualHost>
-        ```
-
-    * **Using swoole:**
-
-        **Important!** Swoole support is still experimental. Use it with care, and report any found issue.
-
-        First you need to install the swoole PHP extension with [pecl](https://pecl.php.net/package/swoole), `pecl install swoole`.
-
-        Once installed, it's actually pretty easy to get shlink up and running with swoole. Just run `./vendor/bin/zend-expressive-swoole start -d` and you will get shlink running on port 8080.
-
-        However, by doing it this way, you are loosing all the access logs, and the service won't be automatically run if the server has to be restarted.
-
-        For that reason, you should create a daemon script, in `/etc/init.d/shlink_swoole`, like this one, replacing `/path/to/shlink` by the path to your shlink installation:
-
-        ```bash
-        #!/bin/bash
-        ### BEGIN INIT INFO
-        # Provides:          shlink_swoole
-        # Required-Start:    $local_fs $network $named $time $syslog
-        # Required-Stop:     $local_fs $network $named $time $syslog
-        # Default-Start:     2 3 4 5
-        # Default-Stop:      0 1 6
-        # Description:       Shlink non-blocking server with swoole
-        ### END INIT INFO
-
-        SCRIPT=/path/to/shlink/vendor/bin/zend-expressive-swoole\ start
-        RUNAS=root
-
-        PIDFILE=/var/run/shlink_swoole.pid
-        LOGDIR=/var/log/shlink
-        LOGFILE=${LOGDIR}/shlink_swoole.log
-
-        start() {
-          if [[ -f "$PIDFILE" ]] && kill -0 $(cat "$PIDFILE"); then
-            echo 'Shlink with swoole already running' >&2
-            return 1
-          fi
-          echo 'Starting shlink with swoole' >&2
-          mkdir -p "$LOGDIR"
-          touch "$LOGFILE"
-          local CMD="$SCRIPT &> \"$LOGFILE\" & echo \$!"
-          su -c "$CMD" $RUNAS > "$PIDFILE"
-          echo 'Shlink started' >&2
-        }
-
-        stop() {
-          if [[ ! -f "$PIDFILE" ]] || ! kill -0 $(cat "$PIDFILE"); then
-            echo 'Shlink with swoole not running' >&2
-            return 1
-          fi
-          echo 'Stopping shlink with swoole' >&2
-          kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE"
-          echo 'Shlink stopped' >&2
-        }
-
-        case "$1" in
-          start)
-            start
-            ;;
-          stop)
-            stop
-            ;;
-          restart)
-            stop
-            start
-            ;;
-          *)
-            echo "Usage: $0 {start|stop|restart}"
-        esac
-        ```
-
-        Then run these commands to enable the service and start it:
-
-        * `sudo chmod +x /etc/init.d/shlink_swoole`
-        * `sudo update-rc.d shlink_swoole defaults`
-        * `sudo update-rc.d shlink_swoole enable`
-        * `/etc/init.d/shlink_swoole start`
-
-        Now again, you can access shlink on port 8080, but this time the service will be automatically run at system start-up, and all access logs will be written in `/var/log/shlink/shlink_swoole.log` (you will probably want to [rotate those logs](https://www.digitalocean.com/community/tutorials/how-to-manage-logfiles-with-logrotate-on-ubuntu-16-04). You can find an example logrotate config file [here](data/infra/examples/shlink-daemon-logrotate.conf)).
-
 * Generate your first API key by running `bin/cli api-key:generate`. You will need the key in order to interact with shlink's API.
-* Finally access to [https://app.shlink.io](https://app.shlink.io) and configure your server to start creating short URLs.
 
-**Bonus**
+### Serve
 
-There are a couple of time-consuming tasks that shlink expects you to do manually, or at least it is recommended, since it will improve runtime performance.
+Once Shlink is configured, you need to expose it to the web, either by using a traditional web server + fast CGI approach, or by using a [swoole](https://www.swoole.co.uk/) non-blocking server.
 
-Those tasks can be performed using shlink's CLI, so it should be easy to schedule them to be run in the background (for example, using cron jobs):
+* **Using a web server:**
 
-* **For shlink older than 1.18.0 or not using swoole as the web server**: Resolve IP address locations: `/path/to/shlink/bin/cli visit:locate`
+    For example, assuming your domain is doma.in and shlink is in the `/path/to/shlink` folder, these would be the basic configurations for Nginx and Apache.
 
-    If you don't run this command regularly, the stats will say all visits come from *unknown* locations.
+    *Nginx:*
 
-* Generate website previews: `/path/to/shlink/bin/cli short-url:process-previews`
+    ```nginx
+    server {
+        server_name doma.in;
+        listen 80;
+        root /path/to/shlink/public;
+        index index.php;
+        charset utf-8;
 
-    Running this will improve the performance of the `doma.in/abc123/preview` URLs, which return a preview of the site.
+        location / {
+            try_files $uri $uri/ /index.php$is_args$args;
+        }
 
-    > **Important!** Generating previews is considered deprecated and the feature will be removed in Shlink v2.
+        location ~ \.php$ {
+            fastcgi_split_path_info ^(.+\.php)(/.+)$;
+            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
+            fastcgi_index index.php;
+            include fastcgi.conf;
+        }
 
-* **For shlink older than v1.17.0**: Update IP geolocation database: `/path/to/shlink/bin/cli visit:update-db`
+        location ~ /\.ht {
+            deny all;
+        }
+    }
+    ```
 
-    When shlink is installed it downloads a fresh [GeoLite2](https://dev.maxmind.com/geoip/geoip2/geolite2/) db file. Running this command will update this file.
+    *Apache:*
 
-    The file is updated the first Tuesday of every month, so it should be enough running this command the first Wednesday.
+    ```apache
+    <VirtualHost *:80>
+        ServerName doma.in
+        DocumentRoot "/path/to/shlink/public"
 
-*Any of these commands accept the `-q` flag, which makes it not display any output. This is recommended when configuring the commands as cron jobs.*
+        <Directory "/path/to/shlink/public">
+            Options FollowSymLinks Includes ExecCGI
+            AllowOverride all
+            Order allow,deny
+            Allow from all
+        </Directory>
+    </VirtualHost>
+    ```
 
-> In future versions, it is planed that, when using **swoole** to serve shlink, some of these tasks are automatically run without blocking the request and also, without having to configure cron jobs. Probably resolving IP locations and generating previews.
+* **Using swoole:**
+
+    First you need to install the swoole PHP extension with [pecl](https://pecl.php.net/package/swoole), `pecl install swoole`.
+
+    Once installed, it's actually pretty easy to get shlink up and running with swoole. Run `./vendor/bin/mezzio-swoole start -d` and you will get shlink running on port 8080.
+
+    However, by doing it this way, you are loosing all the access logs, and the service won't be automatically run if the server has to be restarted.

+    * `sudo update-rc.d shlink_swoole defaults`
+    * `sudo update-rc.d shlink_swoole enable`
+    * `/etc/init.d/shlink_swoole start`
+
+    Now again, you can access shlink on port 8080, but this time the service will be automatically run at system start-up, and all access logs will be written in `/var/log/shlink/shlink_swoole.log` (you will probably want to [rotate those logs](https://www.digitalocean.com/community/tutorials/how-to-manage-logfiles-with-logrotate-on-ubuntu-16-04). You can find an example logrotate config file [here](data/infra/examples/shlink-daemon-logrotate.conf)).
+
+Finally access to [https://app.shlink.io](https://app.shlink.io) and configure your server to start creating short URLs.
+
+### Bonus
+
+Geo-locating visits to your short links is a time-consuming task. When serving Shlink with swoole, the geo-location task is automatically run asynchronously just after a visit to a short URL happens.
+
+However, if you are not serving Shlink with swoole, you will have to schedule the geo-location task to be run regularly in the background (for example, using cron jobs):
+
+The command you need to run is `/path/to/shlink/bin/cli visit:locate`, and you can optionally provide the `-q` flag to remove any output and avoid your cron logs to be polluted.

+## Multiple domains
+
+While in many cases you will just have one short domain and you'll want all your short URLs to be served from it, there are some cases in which you might want to have multiple short domains served from the same Shlink instance.
+
+If that's the case, you need to understand how Shlink will behave when managing your short URLs or any of them is visited.
+
+### Management
+
+When you create a short URL it is possible to optionally pass a `domain` param. If you don't pass it, the short URL will be created for the default domain (the one provided during Shlink's installation or in the `SHORT_DOMAIN_HOST` env var when using the docker image).
+
+However, if you pass it, the short URL will be "linked" to that domain.
+
+> Note that, if the default domain is passed, Shlink will ignore it and will behave as if no `domain` param was provided.
+
+The main benefit of being able to pass the domain is that Shlink will allow the same custom slug to be used in multiple short URLs, as long as the domain is different (like `example.com/my-compaign`, `another.com/my-compaign` and `foo.com/my-compaign`).
+
+Then, each short URL will be tracked separately and you will be able to define specific tags and metadata for each one of them.
+
+However, this has a side effect. When you try to interact with an existing short URL (editing tags, editing meta, resolving it or deleting it), either from the REST API or the CLI tool, you will have to provide the domain appropriately.
+
+Let's imagine this situation. Shlink's default domain is `example.com`, and you have the next short URLs:
+
+* `https://example.com/abc123` -> a regular short URL where no domain was provided.
+* `https://example.com/my-campaign` -> a regular short URL where no domain was provided, but it has a custom slug.
+* `https://another.com/my-campaign` -> a short URL where the `another.com` domain was provided, and it has a custom slug.
+* `https://another.com/def456` -> a short URL where the `another.com` domain was provided.
+
+These are some of the results you will get when trying to interact with them, depending on the params you provide:
+
+* Providing just the `abc123` short code -> the first URL will be matched.
+* Providing just the `my-campaign` short code -> the second URL will be matched, since you did not specify a domain, therefor, Shlink looks for the one with the short code/slug `my-campaign` which is also linked to default domain (or not linked to any domain, to be more accurate).
+* Providing the `my-campaign` short code and the `another.com` domain -> The third one will be matched.
+* Providing just the `def456` short code -> Shlink will fail/not find any short URL, since there's none with the short code `def456` linked to default domain.
+* Providing the `def456` short code and the `another.com` domain -> The fourth short URL will be matched.
+* Providing any short code and the `foo.com` domain -> Again, no short URL will be found, as there's none linked to `foo.com` domain.
+
+### Visits
+
+Before adding support for multiple domains, you could point as many domains as you wanted to Shlink, and they would have always worked for existing short codes/slugs.
+
+In order to keep backwards compatibility, Shlink's behavior when a short URL is visited is slightly different, getting to fallback in some cases.
+
+Let's continue with previous example, and also consider we have three domains that will resolve to our Shlink instance, which are `example.com`, `another.com` and `foo.com`.
+
+With that in mind, this is how Shlink will behave when the next short URLs are visited:
+
+* `https://another.com/abc123` -> There was no short URL specifically defined for domain `another.com` and short code `abc123`, but it exists for default domain (`example.com`), so it will fall back to it and redirect to where `example.com/abc123` is configured to redirect.
+* `https://example.com/def456` -> The fall-back does not happen from default domain to specific ones, only the other way around (like in previous case). Because of that, this one will result in a not-found URL, even though the `def456` short code exists for `another.com` domain.
+* `https://foo.com/abc123` -> This will also fall-back to `example.com/abc123`, like in the first case.
+* `https://another.com/non-existing` -> The combination of `another.com` domain with the `non-existing` slug does not exist, so Shlink will try to fall-back to the same but for default domain (`example.com`). However, since that combination does not exist either, it will result in a not-found URL.
+* Any other short URL visited exactly as it was configured will, of course, resolve as expected.
+
+### Special redirects
+
+It is currently possible to configure some special redirects when the base domain is visited, a URL does not match, or an invalid/disabled short URL is visited.
+
+Those are configured during Shlink's installation or via env vars when using the docker image.
+
+Currently those are all shared for all domains serving the same Shlink instance, but the plan is to update that and allow specific ones for every existing domain.

+# Upgrading
+
+## From v1.x to v2.x
+
+### PHP 7.4 required
+
+This new version takes advantage of several new features introduced in PHP 7.4.
+
+Thanks to that, the code is more reliable and robust, and easier to maintain and improve.
+
+However, that means that any previous PHP version is no longer supported.
+
+### Preview generation
+
+The ability to generate website previews has been completely removed and has no replacement.
+
+The feature never properly worked, and it wasn't really useful. Because of that, the feature is no longer available on Shlink 2.x
+
+Removing this feature has these implications:
+
+* The `short-url:process-previews` CLI command no longer exists, and an error will be thrown if executed.
+* The `/{shortCode}/preview` path is no longer valid, and will return a 404 status.
+
+### Removed paths
+
+These routes have been removed, but have a direct replacement:
+
+* `/qr/{shortCode}[/{size}]` -> `/{shortCode}/qr-code[/{size}]`
+* `PUT /rest/v{version}/short-urls/{shortCode}` -> `PATCH /rest/v{version}/short-urls/{shortCode}`
+
+When using the old ones, a 404 status will me returned now.
+
+### Removed command and route aliases
+
+All the aliases for the CLI commands in the `short-urls` namespace have been removed. If you were using any of those commands with the `shortcode` or `short-code` prefixes, make sure to update them to use the `short-urls` prefix instead.
+
+The same happens for all REST endpoints starting with `/short-code`. They were previously aliased to `/short-urls` ones, but they will return a 404 now. Make sure to update them accordingly.
+
+### JWT authentication removed
+
+Shlink's REST API no longer accepts authentication using a JWT token. The API key has to be passed now in the `x-api-key` header.
+
+Removing this feature has these implications:
+
+* Shlink will no longer introspect the `Authorization` header for Bearer tokens.
+* The `POST /rest/v{version}/authenticate` endpoint no longer exists and will return a 404.
+
+### API version is now required
+
+Endpoints need to provide a version in the path now. Previously, not providing a version used to fall back to v1. Now, it will return a 404 status, as no route will match.
+
+The only exception is the `/rest/health` endpoint, which will continue working without the version.
+
+### API errors
+
+Shlink v1.21.0 introduced support for API errors using the Problem Details format, as well as the v2 of the API.
+
+For backwards compatibility reasons, requests performed to v1 continued to return the old `error` and `message` properties.
+
+Starting with Shlink v2.0.0, both versions of the API will no longer return those two properties.
+
+As a replacement, use `type` instead of `error`, and `detail` instead of `message`.
+
+### Changes in models
+
+The next REST API models have changed:
+
+* **ShortUrl**: The `originalUrl` property was deprecated and has been removed. Use `longUrl` instead.
+* **Visit**: The `remoteAddr` property was deprecated and has been removed. It has no replacement.
+* **VisitLocation**: The `latitude` and `longitude` properties are no longer strings, but float.
+
+### URL validation
+
+Shlink can verify provided long URLs are valid before trying to shorten them. Starting with v2, it no longer does it by default and needs to be explicitly enabled instead of explicitly disabled.
+
+### Removed config options
+
+The `not_found_redirect_to` config option and the `NOT_FOUND_REDIRECT_TO` env var are no longer taken into consideration for the docker image.
+
+Instead, use `invalid_short_url_redirect_to` and `INVALID_SHORT_URL_REDIRECT_TO` respectively.
+
+### Migrated to Laminas
+
+The project has been using Zend Framework components since the beginning. Since it has been re-branded as [Laminas](https://getlaminas.org/), this version updates to the new set of components.
+
+Updating to Laminas components has these implications:
+
+* If you were manually serving Shlink with swoole, the entry script has to be changed from `/path/to/shlink/vendor/bin/zend-expressive-swoole` to `/path/to/shlink/vendor/bin/mezzio-swoole`

-## Supported env vars
+## Other integrations
+
+### Use an external redis server
+
+If you plan to run more than one Shlink instance, there are some resources that should be shared ([Multi instance considerations](#multi-instance-considerations)).
+
+One of those resources are the locks Shlink generates to prevent some operations to be run more than once in parallel (in the future, these redis servers could be used for other caching operations).
+
+In order to share those locks, you should use an external redis server (or a cluster of redis servers), by providing the `REDIS_SERVERS` env var.
+
+It can be either one server name or a comma-separated list of servers.
+
+> If more than one redis server is provided, Shlink will expect them to be configured as a [redis cluster](https://redis.io/topics/cluster-tutorial).
+
+### Integrate with a mercure hub server
+
+One way to get real time updates when certain events happen in Shlink is by integrating it with a [mercure hub](https://mercure.rocks/) server.
+
+If you do that, Shlink will publish updates and other clients can subscribe to those.
+
+There are three env vars you need to provide if you want to enable this:
+
+* `MERCURE_PUBLIC_HUB_URL`: **[Mandatory]**. The public URL of a mercure hub server to which Shlink will sent updates. This URL will also be served to consumers that want to subscribe to those updates.
+* `MERCURE_INTERNAL_HUB_URL`: **[Optional]**. An internal URL for a mercure hub. Will be used only when publishing updates to mercure, and does not need to be public. If this is not provided, the `MERCURE_PUBLIC_HUB_URL` one will be used to publish updates.
+* `MERCURE_JWT_SECRET`: **[Mandatory]**. The secret key that was provided to the mercure hub server, in order to be able to generate valid JWTs for publishing/subscribing to that server.
+
+So in order to run shlink with mercure integration, you would do it like this:
+
+```bash
+docker run \
+    --name shlink \
+    -p 8080:8080 \
+    -e SHORT_DOMAIN_HOST=doma.in \
+    -e SHORT_DOMAIN_SCHEMA=https \
+    -e "MERCURE_PUBLIC_HUB_URL=https://example.com"
+    -e "MERCURE_INTERNAL_HUB_URL=http://my-mercure-hub.prod.svc.cluster.local"
+    -e MERCURE_JWT_SECRET=super_secret_key

 * `DELETE_SHORT_URL_THRESHOLD`: The amount of visits on short URLs which will not allow them to be deleted. Defaults to `15`.
-* `VALIDATE_URLS`: Boolean which tells if shlink should validate a status 20x (after following redirects) is returned when trying to shorten a URL. Defaults to `true`.
-* `NOT_FOUND_REDIRECT_TO`: If a URL is provided here, when a user tries to access an invalid short URL, he/she will be redirected to this value. If this env var is not provided, the user will see a generic `404 - not found` page.

 * `BASE_PATH`: The base path from which you plan to serve shlink, in case you don't want to serve it from the root of the domain. Defaults to `''`.
+* `WEB_WORKER_NUM`: The amount of concurrent http requests this shlink instance will be able to server. Defaults to 16.

+* `DEFAULT_SHORT_CODES_LENGTH`: The length you want generated short codes to have. It defaults to 5 and has to be at least 4, so any value smaller than that will fall back to 4.
+* `GEOLITE_LICENSE_KEY`: The license key used to download new GeoLite2 database files. This is not mandatory, as a default license key is provided, but it is **strongly recommended** that you provide your own. Go to [https://shlink.io/documentation/geolite-license-key](https://shlink.io/documentation/geolite-license-key) to know how to generate it.
 * `REDIS_SERVERS`: A comma-separated list of redis servers where Shlink locks are stored (locks are used to prevent some operations to be run more than once in parallel).

+* `MERCURE_INTERNAL_HUB_URL`: An internal URL for a mercure hub. Will be used only when publishing updates to mercure, and does not need to be public. If this is not provided but `MERCURE_PUBLIC_HUB_URL` was, the former one will be used to publish updates.
+* `MERCURE_JWT_SECRET`: The secret key that was provided to the mercure hub server, in order to be able to generate valid JWTs for publishing/subscribing to that server.
+* `ANONYMIZE_REMOTE_ADDR`: Tells if IP addresses from visitors should be obfuscated before storing them in the database. Default value is `true`. **Careful!** Setting this to `false` will make your Shlink instance no longer be in compliance with the GDPR and other similar data protection regulations.

 ## Multi instance considerations
 
 These are some considerations to take into account when running multiple instances of shlink.
 
-* The first time shlink is run, it generates a charset used to generate short codes, which is a shuffled base62 charset.
-
-    If you are using several shlink instances, you will probably want all of them to use the same charset.
-
-    You can get a shuffled base62 charset by going to [https://shlink.io/short-code-chars](https://shlink.io/short-code-chars), and then you just need to pass it to all shlink instances using the `SHORTCODE_CHARS` env var.
-
-    If you don't do this, each shlink instance will use a different charset. However this shouldn't be a problem in practice, since the chances to get a collision will be very low.
-
 * Some operations performed by Shlink should never be run more than once at the same time (like creating the database for the first time, or downloading the GeoLite2 database). For this reason, Shlink uses a locking system.
 
     However, these locks are locally scoped to each Shlink instance by default.

 ## Versions
 
-Versions of this image match the shlink version it contains.
+Versioning on this docker image works as follows:
 
-For example, installing `shlinkio/shlink:1.15.0`, you will get an image containing shlink v1.15.0.
+* `X.X.X`:  when providing a specific version number, the image version will match the shlink version it contains. For example, installing `shlinkio/shlink:1.15.0`, you will get an image containing shlink v1.15.0.
+* `stable`: always holds the latest stable tag. For example, if latest shlink version is 2.0.0, installing `shlinkio/shlink:stable`, you will get an image containing shlink v2.0.0
+* `latest`: always holds the latest contents in master, and it's considered unstable and not suitable for production.
 
-The `latest` docker tag always holds the latest contents in master, and it's considered unestable and not suitable for production.
-
-> There are no official shlink images previous to v1.15.0.
+> **Important**: The docker image was introduced with shlink v1.15.0, so there are no official images previous to that versions.
