+## This fork
 
 is intended for usage in jenkins jclouds-plugin. Therefore, it is focused on compatibility to jenkins.
 For example: this fork uses guice-6.0.0 instead of 7.0.0. Since apache's JIRA is now readonly, this
 repos has enabled its own github issue tracker.
+
+### First public release is the bugfix release 2.7.1
+
+It provides several bugfixes which did not make it into any release before the project was retired:
+
+- Fixed digitalocean2 provider producing a NumberFormatException.
+- Fixed google-compute-engine provider producing a NumberFormatException.
+- NPE on failure to parse AWSError when determing whether to retry request by Max Smiley
+
+Furthermore, it makes an important change for achieving compatibility to Jenkins:
+- Switch guice-7.0.0 back to guice-6.0.0
+
+## Usage with maven
+
+Obviously, the groupId `org.apache.jclouds` could not be kept. The new groupId is `com.github.felfert.jclouds`.
+So to use this new version with maven, use a snippet like this in your pom.xml:
+```xml
+    <dependency>
+      <groupId>com.github.felfert.jclouds</groupId>
+      <artifactId>jclouds-allcompute</artifactId>
+      <version>2.7.1</version>
+    </dependency>
+```
