+# 2.5.2 Release Notes
+
+The Juju team is proud to release Juju 2.5.2! 
+
+This is a bugfix release of the current stable 2.5 version of Juju. 
+
+Important fixes:
+
+- [LP #1813044](https://bugs.launchpad.net/juju/+bug/1813044) - 2.5.0: race condition when upgrading multiple charms in the same machine
+- [LP #1803247](https://bugs.launchpad.net/juju/+bug/1803247) - unable to determine if a model is a controller model
+- [LP #1814962](https://bugs.launchpad.net/juju/+bug/1814962) - juju run should allow specification of leader units like juju run-action
+- [LP #1815636](https://bugs.launchpad.net/juju/+bug/1815636) - container-inherit-properties=apt-primary,apt-security,apt-sources doesn't work on MAAS provider
+- [LP #1815154](https://bugs.launchpad.net/juju/+bug/1815154) - juju status as admin with non-default format fails on other users' models
+
+For the full list of fixes and additions, see the
+[2.5.2 milestone](https://launchpad.net/juju/+milestone/2.5.2).
+
+## Get Juju
+
+The easiest way to install Juju is by using the `snap` package:
+
+    sudo snap install juju --classic
+
+Those already using the 'stable' snap channel (the default as per the above
+command) should be upgraded automatically. Other packages are available for a
+variety of platforms (see the [install documentation][reference-install]).
+
+## Feedback appreciated
+
+Let us know how you're using Juju or of any questions you may have. You can
+join us on [Discourse][juju-discourse-forum], send us a message on Twitter
+(hashtag `#jujucharms`), or talk to us in the `#juju` IRC channel on
+freenode.
