+## 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.
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#729](https://github.com/shlinkio/shlink/issues/729) Fixed weird error when fetching multiple visits result sets concurrently using mariadb or mysql.
+* [#735](https://github.com/shlinkio/shlink/issues/735) Fixed error when cleaning metadata cache during installation when APCu is enabled.
+* [#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.

-## 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
+    shlinkio/shlink:stable
+```
+
+## All supported env vars
 
 A few env vars have been already used in previous examples, but this image supports others that can be used to customize its behavior.
 
@@ -113,15 +168,12 @@ This is the complete list of supported env vars:
 * `TASK_WORKER_NUM`: The amount of concurrent background tasks this shlink instance will be able to execute. Defaults to 16.
 * `VISITS_WEBHOOKS`: A comma-separated list of URLs that will receive a `POST` request when a short URL receives a visit.
 * `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.
-* `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).
-
-    This is important when running more than one Shlink instance ([Multi instance considerations](#multi-instance-considerations)). If not provided, Shlink stores locks on every instance separately.
-
-    If more than one server is provided, Shlink will expect them to be configured as a [redis cluster](https://redis.io/topics/cluster-tutorial).
-
-    In the future, these redis servers could be used for other caching operations performed by shlink.
-
 * `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_PUBLIC_HUB_URL`: 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`: 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.
