What's new in Zenhub Enterprise 4.0.3

We are thrilled to announce the release of Zenhub Enterprise 4.0.3, packed with a host of exciting new features designed to optimize your workflow, boost productivity, and heighten collaboration.

Features

No new features in this release

Security Fixes

  • Package security updates
  • Patched an application security vulnerability

Bug Fixes

  • Resolved a problem that caused the Chrome Web Store to reject publishing the browser extension due to additional requirements for Manifest V3.

Changes

  • Updated PostgreSQL configuration for improved performance
  • Updated upgrade bundle to improve reliability of upgrades

Known Issues

  • Mozilla recently raised the minimum Firefox version required to run published Firefox extensions from 52.0 to 58.0. This results in failed validation during upload of the Zenhub Firefox extension. Until a fix is released, the workaround is to extract the firefox.zip, update strict_min_version at the bottom of the manifest.json file from 52.0 to 58.0, and re-zip the bundle before upload. If you have any questions, please reach out to enterprise@zenhub.com.
  • In some cases, admin permissions may be lost on upgrade. To restore admin permissions, go to https://<subdomain_suffix>.<domain_tld>:8443/settings and enter the admin username/email
  • When removing "Seats" the available license count doesn't update until a page refresh
  • When using W3ID integration, some users are seeing their name show up as empty
  • In some rare cases, deleting a workspace displays an error message
  • In some rare cases, new users who sign up for Zenhub are taken directly to the board instead of being shown the onboarding form
  • Usage report data from before Zenhub Enterprise v4.0 is not displayed in the admin dashboard
  • When trying to create an account from the login page an 'Account does not exist. Please sign up instead.' error occurs. This is expected behaviour, to create a new account you must use the sign-up page.

Important Upgrade Instructions for Administrators

Zenhub Enterprise for Virtual Machine

⚠️ NOTE: For the upgrade from ZHE 3.5 -> ZHE 4.0, the regular rollback steps cannot be used. Please perform a machine level snapshot prior to upgrading to use as a backup in case you need to revert back to ZHE 3.5 for any reason.

  • You must be running ZHE 3.5.X, 4.0.0, 4.0.1, or 4.0.2 to perform the upgrade to ZHE 4.0.3.

  • For users currently running Zenhub Enterprise, contact our team for a download link for the 4.0.3 upgrade package. The upgrade process is detailed in our documentation.

Zenhub Enterprise for Kubernetes

  • Some extra upgrade instructions have been added specifically for this release due to some database changes that accompany the application updates. Please follow the upgrade instructions below for this release:

⚠️ NOTE: The minimum version of Kubernetes required to run ZHE 4.0 is now v1.24.

1. Prepare

  • Get the kustomization.yaml you configured to setup Zenhub
  • Perform a diff to make sure no outstanding changes are waiting to be applied
kustomize build . | kubectl diff -f-

It should exit 0 and only display a warning of unused variables. If changes are pending, apply them before starting the upgrade process.

  • Make a copy of your existing kustomization.yaml and keep it handy for the next step

2. Update kustomization.yaml

  • Check out the zenhub-enterprise repository at the tag of this release
  • Populate the new kustomization.yaml with your existing configuration values

Be sure to replace any additional customized configuration (such as ingress, TLS configuration) with your original configuration from before as well.

  • In ZHE 4.0, secret_key_base is required to be a 42 byte string, any existing 38 byte string should be updated as described in kustomization.yaml
  • If you are using your own registry and not Zenhub's registry, upload the new images tagged with this release to your registry.

3. Run configmap-generator.sh

Once you have setup all the configurations in your copy of kustomization.yaml and are ready to deploy to your cluster, you must run the configmap-generator.sh script that will fill placeholders in our Kubernetes manifests with your configuration values.

To run the script, navigate to the root of the directory containing your kustomization.yaml file, which also contains the configmap-generator.sh script. Then, run the script with these two commands:

chmod 700 configmap-generator.sh
./configmap-generator.sh

4. Application updates

In your new kustomization.yaml, confirm that the cluster image tags are set to the new images for this release:

If you are using your own registry, ensure that the newName fields are configured for that instead of Zenhub's

images:
  - name: kraken-webapp
    newName: us.gcr.io/zenhub-public/kraken-webapp
    newTag: zhe-4.0.3
  - name: kraken-extension
    newName: us.gcr.io/zenhub-public/kraken-extension
    newTag: zhe-4.0.3
  - name: kraken-zhe-admin
    newName: us.gcr.io/zenhub-public/kraken-zhe-admin
    newTag: zhe-4.0.3
  - name: raptor-backend
    newName: us.gcr.io/zenhub-public/raptor-backend
    newTag: zhe-4.0.3
  - name: toad-backend
    newName: us.gcr.io/zenhub-public/toad-backend
    newTag: zhe-4.0.3
  - name: sanitycheck
    newName: us.gcr.io/zenhub-public/sanitycheck
    newTag: zhe-4.0.3
  - name: devsite
    newName: us.gcr.io/zenhub-public/devsite
    newTag: zhe-4.0.3
  - name: busybox
    newName: docker.io/library/busybox
    newTag: latest
  - name: nginx
    newName: docker.io/library/nginx
    newTag: latest
  • First, delete any raptor-db-migrate and sanitycheck jobs so they may be recreated without errors:

Make sure the status of the jobs are Complete and not Running

kubectl -n <your_dedicated_namespace> delete job/raptor-db-migrate job/sanitycheck
  • Then perform a diff to check what the upgrade will do (this command must be run from the directory that contains your kustomization.yaml
kustomize build . | kubectl diff -f-
  • If everything looks correct and there are no errors, you can deploy to the cluster via:
kustomize build . | kubectl apply -f-

5. Database changes

⚠️ NOTE: Running this script is only required if you are upgrading from ZHE 3.5.

  • Run the script found in k8s-cluster/update/zhe-upgrade.sh via the commands below:

If you use the ZenHub registry

cd update
./zhe-upgrade.sh yourNamespace

If you use your own registry

cd update
./zhe-upgrade.sh yourNamespace yourRegistryName

6. Re Deploy Application

⚠️ NOTE: Running these commands is only required if you are upgrading from ZHE 3.5.

The data migration script run in the previous step will have scaled down the application in order to safely migrate data without active database writes occurring. Now that the migration is complete, the application needs to be deployed to the normal desired operational state:

  • First perform a diff to check what will change (this command must be run from the directory that contains your kustomization.yaml
kustomize build . | kubectl diff -f-
  • If everything looks correct and there are no errors, you can deploy to the cluster via:
kustomize build . | kubectl apply -f-

7. Finalize

  • Securely store the updated kustomization.yaml
