Camunda 8.3
Release date: 10th of October 2023
End of maintenance: 9th of April 2025
Camunda 8 SaaS - Required cluster update
By August 30th, 2024 all automation clusters in Camunda 8 SaaS must be updated to the following versions at a minimum:
- 8.2+gen27
- 8.3+gen11
- 8.4+gen7
- 8.5+gen2
auth0 announced an End-Of-Life for one of the functionalities that is being utilized by previous automation clusters. The new versions are not using this functionality anymore. This update ensures your cluster will work seamlessly after auth0 deactivates the feature in production.
You minimally need to take the following update path:
- 8.0.x -> 8.2+gen27
- 8.1.x -> 8.2+gen27
- 8.2.x -> 8.2+gen27
- 8.3.x -> 8.3+gen11
- 8.4.x -> 8.4+gen7
- 8.5.x -> 8.5+gen2
If you do not update the cluster by August 30th 2024, we will update the cluster for you. Without an update, you would lose access to your cluster.
Camunda 8 Self-Managed clusters are not affected by this.
For existing clusters we recommend updating to 8.3.1 directly and not 8.3.0 due to issues in data migration of Operate, Tasklist, and Optimize that could prolong the migration or even blocking it from finishing.
Zeebe Docker image now runs with unprivileged user by default
The default user in the Zeebe Docker image changed from root to an unprivileged user with the UID 1000. This was done to provide stronger compliance with the OWASP recommendations on Docker Security.
Please refer to the Update 8.2 to 8.3 guide.
The update from 8.2.x to 8.3.x performs a migration for nearly all entities stored in Operate, Tasklist, and Optimize to support multi-tenancy. Therefore, migration may take longer.
Deprecated in 8.3
Web Modeler's beta API was deprecated in 8.3 and will be removed in 8.5.
Use v1 instead, see migration hints.
Zeebe's liveness responsive indicator was removed as part of 8.3.
Versioning changes in Elasticsearch
As of the 8.3 release, Camunda is compatible with Elasticsearch 8.8+ and no longer supports Elasticsearch 7.x. See supported environments which you can download here.
Versioning changes in Helm chart
Helm charts versioning changed in July 2023.
Starting from July 2023 (v8.2.8), the Camunda 8 Helm chart version follows the same unified schema and schedule as Camunda 8 applications.
Before this change, the Camunda 8 Helm chart version only followed the minor version.
Camunda 8.2
Release date: 11th of April 2023
End of maintenance: 8th of October 2024
Update from Web Modeler 8.2 to a later minor version
Web Modeler versions 8.2.7 to 8.2.12 are affected by camunda/issues#677.
If you are using one of these versions, you should first update to Web Modeler 8.2.13 (or a subsequent patch version) before upgrading to a later minor version (8.3 or higher).
If your current version of Web Modeler is 8.2.6 or earlier, you may directly upgrade to a later minor version.
Do not update to Camunda 8.2.22
Zeebe release 8.2.22 suffers from camunda/zeebe#16406, which results in a Zeebe broker being unable to start if at least one DMN model is deployed. We urge users to skip this release and update to 8.2.23 right away.
Do not update from Camunda 8.1.X to 8.2.6
An issue in the Operate 8.2.6 patch was discovered after it was published on June 8th.
You should not update directly from 8.1.x to 8.2.6 (it will require manual intervention as indices break), you either first update to 8.2.5 then 8.2.6 or straight from 8.1.x to 8.2.7.
To prevent this entirely we removed the Operate 8.2.6 artifacts from this release.
As Camunda 8.2.7 was already released on Tuesday Jun 13th, you can just update to 8.2.7 directly, skipping 8.2.6.
OpenSearch 1.3.x support
- Operate version 8.2+ support OpenSearch 1.3.x. However, 8.2.x patches will only be released on the OS 1.3 branch until end of 2023 given that OS 1.3 maintenance period ends by then. We recommend customers to go to 8.4.x which supports OS 2.5+.
Optimize and Helm chart compatibility
For Optimize 3.10.1, a new environment variable introduced redirection URL. However, the change is not compatible with Camunda Helm charts until it is fixed in 3.10.3 (and Helm chart 8.2.9). Therefore, those versions are coupled to certain Camunda Helm chart versions:
| Optimize version | Camunda Helm chart version |
|---|---|
| Optimize 3.10.1 & Optimize 3.10.2 | 8.2.0 - 8.2.8 |
| Optimize 3.10.3+ | 8.2.9 - 8.2.22 |
| Optimize 8.2.7+ | 8.2.23+ |
Camunda 8.1
Release date: 11th of October 2022
End of maintenance: 10th of April 2024
Do not update to Camunda 8.1.23
Zeebe release 8.1.23 suffers from camunda/zeebe#16406, which results in a Zeebe broker being unable to start if at least one DMN model is deployed. We urge users to skip this release and update to 8.1.24 right away.
Camunda 8.0
Release date: 12th of April 2022
End of maintenance: 11th of October 2023
Camunda 8.0.15 release is skipped
The Camunda 8.0.15 release pipeline lead to corrupted Zeebe 8.0.15 artifacts getting published.
The whole Camunda 8.0.15 release was thus skipped and updates from Camunda 8.0.14 should go straight to Camunda 8.0.16.
Deprecated in 8.0
The DeployProcess RPC was deprecated in 8.0. It is replaced by the DeployResource RPC.
Camunda Cloud 1.3
Release date: 11th of January 2022
Camunda Cloud is out of maintenance.
Deprecated in 1.3
The zeebe-test module was deprecated in 1.3.0. We are currently planning to remove zeebe-test for the 1.4.0 release.
Camunda Cloud 1.2
Release date: 12th of October 2021
Camunda Cloud is out of maintenance.
Camunda Cloud 1.1
Release date: 13th of July 2021
Camunda Cloud is out of maintenance.
Camunda Cloud 1.0
Release date: 11th of May 2021
Camunda Cloud is out of maintenance.
Removed in 1.0
The support for YAML processes was removed as of release 1.0. The resourceType in Deployment record and Process grpc request are deprecated; they will always contain BPMN as value.
Zeebe 0.26.0
Deprecated in 0.26.0
YAML workflows descriptions
YAML workflows are an alternative way to specify simple workflows using a proprietary YAML description. This feature is deprecated and no longer advertised in the documentation. YAML workflows gained little traction with users and we do not intend to support them in the future.
We recommend all users of YAML workflows to migrate to BPMN workflows as soon as possible. The feature will eventually be removed completely, though the date when this will occur has yet to be defined.
Zeebe 0.23.0-alpha2
Deprecated in 0.23.0-alpha2
- TOML configuration - deprecated and removed in 0.23.0-alpha2
- Legacy environment variables - deprecated in 0.23.0-alpha2, removed in 0.25.0
New configuration:
exporters:
elasticsearch:
className: io.camunda.zeebe.exporter.ElasticsearchExporter
debughttp:
className: io.camunda.zeebe.broker.exporter.debug.DebugHttpExporter
In terms of specifying values, there were two minor changes:
- Memory sizes are now specified like this:
512MB(old way:512M) - Durations (e.g. timeouts) can now also be given in ISO-8601 Durations format. However, you can still use the established method and specify a timeout of
30s
