Announcing supported versions for Charmed Temporal

To deliver a more reliable and reproducible experience, the Workflows team is introducing supported versions of Charmed Temporal, backed by clear versioning and support policies.

What is a supported version - and why it matters

A supported version is a stable release of Charmed Temporal that has undergone thorough development and validation. These versions receive ongoing security updates and critical bug fixes, ensuring production-grade reliability.

Previously, users deployed Charmed Temporal using the latest/edge or latest/stable channels, often pinning specific charm revisions. Going forward, Charmhub tracks will define which Temporal version is deployed, eliminating the need for manual revision management.

This change introduces better predictability, reproducibility, and stability for deployments.

Key changes

  • latest/ will no longer be the default and recommended channel to deploy Charmed Temporal from.
  • latest/ will only receive updates if there is a fix for an issue that prevents users from upgrading to 1.23/stable. It will not receive new features, and revisions previously recommended by the documentation will not be maintained.
  • Deployments from latest/edge are not guaranteed to work after the first supported version is released.
  • The latest/stable track will stop receiving updates as 1.23/stable becomes the default.
  • 1.23/stable will become the only recommended track for production environments until it is no longer supported.
  • 1.23/stable will follow the Workflows team’s support policy.

Action required

To maintain a smooth upgrade path, all users should transition to the latest supported version. To do so:

1. Check the current revisions of your Temporal Server and Admin charms

juju status temporal-k8s
juju status temporal-admin-k8s

Sample output for an operator on latest/stable:

App             Version  Status  Scale  Charm               Channel        Rev  Address         Exposed  Message
temporal-k8s    1.23.1   active      1  temporal-k8s        latest/stable   43  10.152.183.245  no

App             Version  Status  Scale  Charm               Channel        Rev  Address         Exposed  Message
temporal-admin  1.23.1   active      1  temporal-admin-k8s  latest/stable   13  10.152.183.155  no

If your Channel already shows 1.23/stable, no migration is required. You are already on the supported version.

2. Follow the upgrade guide

Upgrade from latest/stable → 1.23/stable
