Release Notes and Upgrade Instructions

KHEOPS is composed of a number of Docker Images. All the docker images belonging to a single version and meant to run together are tagged with the same version number. As a general rule, upgrading versions is simply a matter of updating the tag on the docker images. Additional steps that need to be performed are detailed below. KHEOPS uses Liquibase to manage the database schema, the database will be automatically upgraded.

As with any upgrade - make sure to perform a backup of the database used by KHEOPS before performing an upgrade.

v1.0.6

Changes

Display delete contact email in the UI. When the following environment variables are set, a new line is added to the delete message, prompting the user to contact the email address provided, if he wants to permanently delete the data.

Upgrade

New optional environment variable KHEOPS_UI_SHOW_DELETE_CONTACT for the kheops-ui container.
New optional environment variable KHEOPS_UI_DELETE_CONTACT for the kheops-ui container (obligatory ifKHEOPS_UI_SHOW_DELETE_CONTACT is set to true).

To use:

Set the KHEOPS_UI_SHOW_DELETE_CONTACT environment variable to true, to enable showing the email address set in the next variable. Use together with the next variable, KHEOPS_UI_DELETE_CONTACT.
Set the KHEOPS_UI_DELETE_CONTACT : if you set this variable to an email address: when a user is deleting a study, he will be notified to contact this email address if he wants to permanently delete it. Only set this when the previous variable KHEOPS_UI_SHOW_DELETE_CONTACT, is set to true.

For example:

KHEOPS_UI_SHOW_DELETE_CONTACT=true
KHEOPS_UI_DELETE_CONTACT=[email]@[address].ch

Permanently deleting a series or study is now possible, through an API call, completely removing its data. The permanent deletion is only possible if using the Dcm4Chee PACS - which is by default the case for KHEOPS.
(API) Mutation:
- The Delete Series API Documentation has been updated to add Permanent Delete, in the Headers section.
- The Delete Study API Documentation has been updated to add Permanent Delete, in the Headers section.

Upgrade

(Optional) Only if you want to enable Permanent Delete. Otherwise, no action is necessary.

Create a new file kheops_auth_admin_password in the secrets folder eg by running printf "%s\n" $(docker run --rm osirixfoundation/openssl rand -base64 32 | tr -dc '[:print:]') > kheops_auth_admin_password
Update the docker-compose.yml file:
- In the secrets section of kheops-authorization add a new secret: kheops_auth_admin_password
- In the secrets section at the end of the file add
```
kheops_auth_admin_password:
file: secrets/kheops_auth_admin_password
```
Update the docker-compose.env file and add KHEOPS_PROXY_PACS_DCM4CHEE_ARC=http://pacsarc:8080/dcm4chee-arc after the KHEOPS_PROXY_PACS_WADO_RS line.
Restart KHEOPS by running docker-compose down followed by a docker-compose up -d

v1.0.2

Changes

Minor UI updates.

Upgrade

No additional upgrade steps are necessary.

v1.0.1

Changes

Better logs when verifying instance (add boolean field ‘isValid’ and unmatching field in logs).

Upgrade

No additional upgrade steps are necessary.

v1.0.0

Changes

Validation instance metadata before uploading.
Fixed issue for metrics.
Autocomplete for user email address (send, add to an album).
Fixed silent login.
UI:
- Many fixes.
- Before removing or downgrading an admin from an album, the user will be informed that if he performs this action some capabilities token will be revoked at the same time. Because they were created by the user.
- Before exiting an album, the user will be informed that if he performs this action some capabilities token will be revoked at the same time. Because they were created by himself.
Removed filebeat and metricbeat from containers (kheops-authorization, kheops-reverse-proxy and pacs-authorization-proxy). Now one filebeat and one metricbeat are used as sidecar containers (kheops-authorization-metricbeat and kheops-filebeat-sidecar).
(API) Mutation:
- Can be filtered by user, seriesUID, studyUID, capabilityTokenID, date, type, … (documentation)
- Field origin renamed to source.
- Field capability renamed to capability_token.
- Add boolean field is_admin in source if the user is always a member of the album.
- If the mutaion was made by a report provider or a capability token : the related informations are moved to source.
- mutation_type=NEW_REPORT is now mutation_type=NEW_SERIES with the report_provider in source
- Add field series when the mutation type is ADD_STUDY and REMOVE_STUDY. This new field is an array of series.
- Field series is now an array with only one series when the mutation type is ADD_SERIES and REMOVE_SERIES.
- Add boolean field is_prensent_in_album for each series. It indicate if the series is present in the album.

- New webhooks for remove_series and delete_album. (documentation).
- If new instances are uploaded to Kheops, a webhook is triggered for each album containing the series.
(API) Capabilities:
- Add a field revoked_by with the user who revoked the album capability token. (documentation)
Database:
- New table event_series
- New column revoked_by in table capabilities set with a user pk when the album capabilitie token is revoked otherwise the field is Null.
- Remove column series_fk in table events
Log:
- kheops-authorizion : the file /usr/local/tomcat/conf/logging.properties rotate after 5 days (90 previously).

Upgrade

No additional upgrade steps are necessary.

v0.9.4

When upgrading, make sure to install and run v0.9.3 prior to installing v0.9.4.

Changes

Removed dependency on Keycloak.
UI Improvements.

Upgrade

Environment variable KHEOPS_KEYCLOAK_URI is no longer used.
Environment variable KHEOPS_KEYCLOAK_REALMS is no longer used.
Environment variable KHEOPS_KEYCLOAK_CLIENTID is no longer used.

v0.9.3

Transition version to v0.9.4

Versions of KHEOPS up to v0.9.2 had a strong dependency on Keycloak. Only the user’s ID (sub) was stored in the KHEOPS database, and KHEOPS would use Keycloak APIs and a service account (kheopsAuthorization) to discover a user’s name and email address.

Starting with v0.9.4, KHEOPS uses exclusively OpenID Connect (OIDC) for user authentication. v0.9.3 is a transition release that is still dependent on Keycloak, and retrieves the user names and emails from Keycloak at startup.

While we still expect Keycloak to be used in the majority of cases. It will now be possible to use other OIDC providers directly, without installing Keycloak.

Changes

Loads user profile information from Keycloak at startup.
Updates user profile information at each login.
UI Improvements.

Upgrade

Add Environment variable KHEOPS_OIDC_PROVIDER which is a URL that points to the OpenIDConnect Provider.

The full path to the OIDC provider must be set. Its value will typically be ${KHEOPS_KEYCLOAK_URI}/auth/realms/${KHEOPS_KEYCLOAK_REALMS}

For example: If the KHEOPS_KEYCLOAK_URI is https://keycloak.kheops.online, and the KHEOPS_KEYCLOAK_REALMS is demo, the value of KHEOPS_OIDC_PROVIDER would be https://keycloak.kheops.online/auth/realms/demo.
Environment variables KHEOPS_ROOT_SCHEME, KHEOPS_ROOT_HOST, and KHEOPS_ROOT_PORT are replaced by KHEOPS_ROOT_URL.

The value of KHEOPS_ROOT_URL will typically be ${KHEOPS_ROOT_SCHEME}://${KHEOPS_ROOT_HOST}[:${KHEOPS_ROOT_PORT}]. If the port is the default port for the scheme (e.g., 443 for https), it can be omitted. For example: https://demo.kheops.online.
Environment variable KHEOPS_UI_KEYCLOAK_CLIENTID is renamed KHEOPS_UI_CLIENTID
Make sure that the KHEOPS UI login client in Keycloak has the web-origins, email, and profile Client Scope as an Assigned Default Client Scope.
KHEOPS_UI_USER_MANAGEMENT_URL is a new optional environment variable that can be set to provide a page where a user can access user settings.

If using Keycloak, this value would probably be set to ${KHEOPS_OIDC_PROVIDER}/account. For example: https://keycloak.kheops.online/auth/realms/demo/account

Notes for upgrading for nonsecure install

Pass the backend docker network hostname of the Keycloak server using the KHEOPS_OIDC_PROVIDER environment variable to the kheops-authorization Docker container in the docker-compose.yml file.
```
    environment:
      KHEOPS_OIDC_PROVIDER:http://keycloak:8080/auth/realms/kheops
```
Pass the frontend URL to the keycloak container using the KEYCLOAK_FRONTEND_URL environment variable in the docker-compose.yml file
```
    environment:
      KEYCLOAK_FRONTEND_URL: http://127.0.0.1:8080/auth
```
Remove the KHEOPS_KEYCLOAK_URI environment variable from kheops-ui in the docker-compose.yml file.
The -noissuer tag for the osirixfoundation/kheops-authorization image is no longer needed.
