Juju Roadmap & Releasesยถ

This document is about our releases of Juju, that is, the juju CLI client and the Juju agents.

  • We release new minor version (the โ€˜xโ€™ of m.x.p) approximately every 3 months.

  • Patch releases for supported series are released every month

  • Once we release a new major version, the latest minor version of the previous release will become an LTS (Long Term Support) release.

  • Minor releases are supported with bug fixes for a period of 4 months from their release date, and a further 2 months of security fixes. LTS releases will receive security fixes for 12 years.

  • 4.0 is an exception to the rule, as it is still under development. We plan on releasing beta versions that are content driven and not time.

The rest of this document gives detailed information about each release.

โญ Juju 3.6ยถ

April 2036: expected end of security fix support

1 May 2026: expected end of bug fix support

Note

Juju 3.6 series is LTS

๐Ÿ”ธ Juju 3.6.10ยถ

๐Ÿ—“๏ธ 23 Sep 2025

For a detailed list of every commit in this release, refer to the Github Release Notes .

โš™๏ธ Features:

New Google Cloud provider functionalityยถ

The Google Cloud provider gains support for various features already available on other clouds like AWS or Azure. Specifically, the following features are now available:

VPC selection
Use the vpc-id model config value to select the name of the VPC to use for that model. This is supplied when the model is added:
juju add-model mymodel --config vpc-id=myvpc
or at bootstrap for the controller model:
juju bootstrap google mycontroller --config vpc-id=myvpc

For a VPC to be used when bootstrapping, there must be a firewall ruling allowing SSH traffic.

Spaces support and subnet placement
Compute instances can now be provisioned such that space constraints and subnet placement can be used. Subnet placement can use either the subnet name or subnet CIDR.
eg
juju deploy mycharm --constraints="spaces=aspace" juju deploy mycharm --constraints="subnet=asubnet" juju deploy mycharm --constraints="subnet=10.142.0.0/16"

ssh-allow model config
The ssh-allow model config value is now supported. When specified, a firewall rule is created to control ingress to the ssh port.
eg
juju model-config ssh-allow="192.168.0.0/24"

Service account credentials
Similar to using instance roles on AWS or managed identities on Azure, itโ€™s now possible to use service accounts to confer permissions to Juju controllers such that a credential secret is not required. The service account to be used must have the following scopes:

  • https://www.googleapis.com/auth/compute

  • https://www.googleapis.com/auth/devstorage.full_control

If you are not on a jump host, you must bootstrap using a standard credential and specify the service account like so:
juju bootstrap google mycontroller --bootstrap-constraints="instance-role=mydevname@2@developer.gserviceaccount.com"

If you are on a jump host, you can set up a credential using juju add-credential google. Select credential type service-account and enter the service account email. Then bootstrap as normal:
juju bootstrap google mycontroller

Constrains with image-id
The use of the image-id constraint value is now supported.
eg
juju deploy mycharm --constraints="image-id=someimageid"

Preview: support for --attach-storage on Kubernetes modelsยถ

For this release, a feature flag needs to be used as the feature is in preview. On the client machine used to run the Juju CLI, simply:
export JUJU_DEV_FEATURE_FLAGS=k8s-attach-storage

The primary use case this feature is designed to solve is to provide the ability to re-use volumes that have been restored from a backup and attach them to units when deploying or scaling. The basic steps follow the usual import and attach workflow supported already on other clouds:

  1. Import the PV into the Juju model to create a detached storage instance.

  2. Use the imported storage with the --attach-storage option for deploy or add-unit.
    eg

juju import-filesystem kubernetes <mypvname>
# See the resulting detached storage instance.
juju status --storage
juju deploy postgresql-k8s --trust --attach-storage <storagename>

Note that if the PV to be imported still has a reference to a PVC, the --force option is needed when importing since the existing claim reference will be removed.

Removal of charm metricsยถ

Charm metrics are no longer supported. This means that the collect-metrics and meter-status-changed hooks will no longer fire and the add-metrics hook command becomes a no-op. In addition, the Juju CLI commands metrics, collect=metrics, and set-meter-status are removed.

Documentation improvementsยถ

Many documentation improvements have been done for this release. Highlights include:

  • better support for diagrams in dark mode

  • visual enhancements to tips and notes

  • removal of command aliases from CLI doc to reduce clutter

  • hook and storage reference doc improvements

๐Ÿ› ๏ธ Fixes:

Openstackยถ

The 3.6.9 release introduced a regression when running on Openstack clouds where security groups are disabled.

Google cloudยถ

Specifying non-default disk storage using storage pools is fixed. Using images configured for pro support is fixed.

Kubernetesยถ

Deletion of applications deployed using sidecar charms now also deletes any Kubernetes resources created directly by the charm and not managed by Juju. These include:

  • custom resource definitions

  • config maps

  • deployments, daemonsets

  • etc

Adding multiple secrets simultaneously could result in an error and this has been fixed. Fixes for issues scaling applications:

  • fix logic to only consider units >= target scale for removal, preventing inappropriate scaling during scale-up scenarios.

  • only initiate scaling when all excess units (>= target) are dead. The credential-get hook command now works on Kubernetes models for trusted applications the same way as for VM models.

LXDยถ

When a model is deleted, any LXD profiles created for the model and its applications are now removed. The profile naming scheme has been updated to include a reference to the model UUID as well as name to ensure profiles are fully disambiguated. Upon upgrade to this Juju version, existing profiles are renamed as needed.

The new profile names are of the form:
juju-<model>-<shortid> or juju-<model>-<shortid>-<app>-<rev>

๐Ÿ”ธ Juju 3.6.9ยถ

๐Ÿ—“๏ธ 20 Aug 2025

โš™๏ธ Features:

New cloud regionsยถ

Increased secret content sizeยถ

The secret content size limit has been increased from 8KiB to 1MiB.

Other featuresยถ

๐Ÿ› ๏ธ Fixes:

Openstackยถ

The Openstack Neutron API endpoint was incurring excessive calls due to an inefficient query strategy.
SEV flavors are deprioritised when using constraints to choose a flavor as they are not yet modelled.

Azureยถ

LXDยถ

The LXD provider now supports zone constraints.
There are also storage fixes for deploying a charm with multiple storage requirements.

Kubernetesยถ

The memory request and limit has been reduced for the charm container and no longer uses the same (possibly large) value that may have been required for the workload.
The default image repository is now ghcr rather than docker.

Storageยถ

A long occurring intermittent storage bug was fixed where sometimes storage would not be registred as attached and charms would hang and not run the storage attached hook.

FAN networkingยถ

If the container networking method is set to โ€œlocalโ€ or โ€œproviderโ€, do not set up FAN networking.

Mitigate possible connection leakยถ

The worker to monitor and update external controller API addreses for cross model relations could needlessly and constantly bounce due to incorrect detection of address changes. This would cause HTTP connections to churn, possibly contributing to observed connection / file handle leaks.

Removal of Juju GUIยถ

Juju GUI is no longer deployed and the โ€“no-gui flag was dropped from juju bootstrap. The Juju Dashboard replaces the GUI and is deployed using the juju-dashboard charm.

Windows charms no longer supportedยถ

Windows charms are no longer supported.

Bionic and earlier workloads no longer supportedยถ

Only workloads on focal and later are supported.

No longer create default model on bootstrapยถ

Running juju bootstrap no longer creates a default model. After bootstrap you can use add-model to create a new model to host your workloads.

add-k8s helpers for aks, gke, eksยถ

The Juju add-k8s command no longer supports the options โ€œโ€“aksโ€, โ€œโ€“eksโ€, โ€œโ€“gkeโ€ for interactive k8s cloud registration. The strict snap cannot execute the external binaries needed to enable this functionality. The options may be added back in a future update.

Note: itโ€™s still possible to register AKS, GKE, or EKS clusters by passing the relevant kube config to add-k8s directly.

Deprecated traditional kubernetes charmsยถ

Traditional kubernetes charms using the pod-spec charm style are deprecated in favor of newer sidecar kubernetes charms.

From juju 3.0, pod-spec charms are pinned to Ubuntu 20.04 (focal) as the base until their removal in a future major version of juju.

Rackspace and Cloudsigma providers no longer supportedยถ

Rackspace and Cloudsigma providers are no longer supported

Whatโ€™s Newยถ

Juju Dashboard replaces Juju GUIยถ

The Juju Dashboard replaces the GUI; it is deployed via the juju-dashboard charm, which needs to be integrated with the controller application in the controller model.

juju bootstrap
juju switch controller
juju deploy juju-dashboard
juju integrate controller juju-dashboard
juju expose juju-dashboard

After the juju-dashboard application shows as active, run the dashboard command:

juju dashboard

Note: the error message which appears if the dashboard is not yet ready needs to be fixed. (https://bugs.launchpad.net/juju/+bug/1994953 )

Actionsยถ

The client side actions UX has been significantly revamped. See the doc here: https://juju.is/docs/olm/manage-actions

To understand the changes coming from 2.9 or earlier, see the post here: https://discourse.charmhub.io/t/juju-actions-opt-in-to-new-behaviour-from-juju-2-8/2255

Secretsยถ

It is now possible for charms to create and share secrets across relation data. This avoids the need for sensitive content to be exposed in plain text. The feature is most relevant to charm authors rather than end users, since how charms use secrets is an internal implementation detail for how workloads are configured and managed. Nonetheless, end users can inspect secrets created by deployed charms:

https://juju.is/docs/olm/secret

https://juju.is/docs/olm/manage-secrets

Charm authors can learn how to use secrets in their charms:

https://juju.is/docs/sdk/add-a-secret-to-a-charm

https://juju.is/docs/sdk/secret-events

Juju controller applicationยถ

The controller model has a Juju controller application deployed at bootstrap. This application currently provides integration endpoints for the Juju dashboard charm. Future work will support integration with the COS stack and others.

MongoDB server-side transactions now defaultยถ

Since the move to mongo 4.4 in juju 2.9, juju now uses server-side transactions.

Fixes ๐Ÿ› ๏ธยถ

  • deploy k8s charms to juju 3.0 beta is broken (LP1947105 )

  • Juju bootstrap failing with various Kubernetes (LP1905320 )

๐Ÿ”ธ Juju 2.9.8ยถ

๐Ÿ—“๏ธ 13 Jul 2021

This release introduces support for bootstrapping and deploying workloads to Equinix cloud. To try out the new provider:

  • Run juju update-public-clouds --client to ensure that provider API endpoint list is up to date.

  • Add a credential for the equinix cloud (juju add-credential equinix). You will need to specify your equinix project ID and provide an API key. You can use the equinix console to look up your project ID and generate API tokens.

  • Select a metro area and bootstrap a new controller. For example to bootstrap to the Amsterdam data-center you may run the following command: juju bootstrap equinix/am.

Caveats:

  • Due to substrate limitations, the equinix provider does not implement support for firewalls. As a result, workloads deployed to machines under the same project ID can reach each other even across Juju models.

  • Deployed machines are always assigned both a public and a private IP address. This means that any deployed charms are implicitly exposed and proper access control mechanisms need to be implemented to prevent unauthorized access to the deployed workloads.

This release also introduces logging labels which will help with the aggregation of logs via a label rather than a namespace.

juju model-config "logging-config='#http=TRACE'"

The above will turn on HTTP loggers to trace. This is a new UX feature to help with debugging, itโ€™s not been full worked through Juju yet and might be subject to change.
