The 'welcome' theme has has been updated to use a new layout and now uses PatternFly 5, rather than PatternFly 3. If you are extending the theme, or providing your own, you may need to update it as follows:
== Migrate from PatternFly 3 to PatternFly 5
The welcome theme was one of the more outdated themes in Keycloak. It was originally based on PatternFly 3, but has now been updated to use PatternFly 5, skipping a major version in the process. This means that if your custom theme extends the built-in theme you will need to update it to use PatternFly 5 syntax. Consult the https://www.patternfly.org/get-started/develop/[PatternFly 5 documentation] for details.
If you are still using PatternFly 3 in your own custom theme (not extending the built-in one), you can continue to use it, but PatternFly 3 support will be removed in a future release, so you should consider migrating to PatternFly 5 as soon as possible.
If the Administration Console is enabled, the welcome page will automatically redirect to it if the administrative user already exists. This behavior can be modified by setting the `redirectToAdmin` in your `theme.properties` file. By default, the property is set to `false`, unless you are extending the built-in theme, in which case, the property is set to `true`.
== The `documentationUrl` and `displayCommunityLinks` properties have been removed.
These properties were previously used for navigational elements that are now no longer present. If you are extending the built-in theme, you will need to remove these properties from your `theme.properties` file, as they no longer have any effect.
== Assets are now loaded from 'common' resources
Images such as the background, logo and favicon are now loaded from the 'common' resources, rather than the theme resources. This change means that if you are extending the built-in theme, and are overwriting these images, you will need to move them to the 'common' resources of your theme, and update your `theme.properties` file to include the new paths:
If you are loading Keycloak JS directly from the Keycloak server, this section can be safely ignored. If you are loading Keycloak JS from the NPM package and are using a bundler like Webpack, Vite, and so on, you might need to make some changes to your code. The Keycloak JS package now uses the https://webpack.js.org/guides/package-exports/[`exports` field] in the package.json file. This means that you might have to change your imports:
It is no longer allowed to have the same feature in both the `--features` and `--features-disabled` list. The feature should appear in only one list.
The usage of unversioned feature names, e.g. `docker`, in the `--features` list will allow for the most supported / latest feature version to be enabled for you.
If you need more predictable behavior across releases, reference the particular version you want instead, e.g. `docker:v1`.
Default user profile configuration comes with a set of default validations for the basic predefined fields. Those validations were not present in previous versions when the `declarative-user-profile` feature was disabled by default.
If you have issues due the backwards compatibility, you can change the default validators according to your needs. The default validators are as follows:
* The`username`, `email`, `firstName` and `lastName` attributes have a maximum length of 255 characters. These validations were indirectly present in previous versions as well
due there is a database constraint on the table `USER_ENTITY` for those fields with a maximum length of 255 characters. However when using user storage providers, it might be possible before to use longer values.
* The `username` attribute has a minimum length of three characters. Username has also `username-prohibited-characters` and `up-username-not-idn-homograph` validator by default, which were not present in previous versions.
See the link:{adminguide_link}#user-profile[Validation section of the User Profile Documentation] for the details about those attributes. Note that username is not editable by default unless you have the realm switch `Edit username enabled`.
This change means that existing users with incorrect usernames should still work and they will not be enforced to update their usernames. But new users will be enforced to use correct usernames
during their registration or creation by the admin REST API.
* Attributes `firstName` and `lastName` have the `person-name-prohibited-characters` validator on them, which were not present in previous versions.
See the link:{adminguide_link}#user-profile[Validation section of the User Profile Documentation] for the details about those attributes. Note that both first
name and last name are editable by default, so users, who already have such incorrect first/last name from a previous version will be forced to update them when updating their user profiles.
== User attribute names with strange characters
In previous versions, it was possible to create a user with attribute names like `some:attribute` or `some/attribute`. User profile intentionally does not allow you to create
attributes with such strange names in the user profile configuration. So you may need to configure `Unmanaged attributes` for your realm and enable unmanaged attributes for administrators
(ideally) or for end users (if really needed). Although it is strongly preferred to avoid using such attribute names.
== Verify Profile required action enabled by default
The required action `verify-profile` is enabled by default for new realms. But when you are migrating from previous version, your existing realms will have same state of this `verify-profile` action as before, which
usually means disabled as it was disabled by default in previous versions. For the details about this required action, see the link:{adminguide_link}#user-profile[User Profile Documentation].
The `spi-truststore-file-*` options and the truststore related options `https-trust-store-*` are deprecated, please use the new default location for truststore material, `conf/truststores`, or specify your desired paths via the `truststore-paths` option. For details refer to the relevant https://www.keycloak.org/server/keycloak-truststore[guide].
The `tls-hostname-verifier` property should be used instead of the `spi-truststore-file-hostname-verification-policy` property.
The `--proxy` option has been deprecated and will be removed in a future release. The following table explains how the deprecated option maps to supported options.
|`kc.sh --hostname-port 80\|443` (depending if HTTPS is used)
|`kc.sh --proxy reencrypt`
|`kc.sh --proxy-headers forwarded\|xforwarded`
|===
NOTE: For hardened security, the `--proxy-headers` option does not allow selecting both `forwarded` and `xforwarded` values at the same time (as it was
the case before for `--proxy edge` and `--proxy reencrypt`).
If you are using the User Profile SPI in your extension, you might be impacted by the API changes introduced in this release.
The `org.keycloak.userprofile.Attributes` interface includes the following changes:
* Method `getValues` was renamed to `get` to make it more aligned with the same operation from a regular Java `Map`
* Method `isRootAttribute` was moved to the utility class `org.keycloak.userprofile.UserProfileUtil.isRootAttribute`
* Method `getFirstValue` was renamed to `getFirst` to make it less verbose
* Method `getReadable(boolean)` was removed and now all attributes (including root attributes) are returned whenever they have read rights.
= Changes to the user representation in both Admin API and Account contexts
Both `org.keycloak.representations.idm.UserRepresentation` and `org.keycloak.representations.account.UserRepresentation` representation classes have changed
so that the root user attributes (such as `username`, `email`, `firstName`, `lastName`, and `locale`) have a consistent representation when fetching or sending
the representation payload to the Admin and Account APIS, respectively.
The `username`, `email`, `firstName`, `lastName`, and `locale` attributes were moved to a new `org.keycloak.representations.idm.AbstractUserRepresentation` base class.
Also the `getAttributes` method is targeted for representing only custom attributes, so you should not expect any root attribute in the map returned by this method. This method is
mainly targeted for clients when updating or fetching any custom attribute for a give user.
In order to resolve all the attributes including the root attributes, a new `getRawAttributes` method was added so that the resulting map also includes the root attributes. However,
Option `https-client-auth` had been treated as a run time option, however this is not supported by Quarkus. The option needs to be handled at build time instead.
= Changes to Freemarker templates to allow rendering pages based on the user profile configuration set to a realm
In this release, the following templates were updated to make it possible to dynamically render attributes based
If you use a custom theme to change these templates, they will function as expect because only the content is updated.
However, we recommend you to take a look at how to configure a link:{adminguide_link}#user-profile[{declarative user profile}] and possibly avoid
changing the built-in templates by using all the capabilities provided by this feature.
Also, the templates used by the `declarative-user-profile` feature to render the pages for the same flows are longer necessary and removed in this release:
* `update-user-profile.ftl`
* `register-user-profile.ftl`
If you were using the `declarative-user-profile` feature in previously releases with customizations to the above templates,
update the `login-update-profile.ftl` and `register.ftl` accordingly.
= The update profile page when logging in for the first time through a broker now have its own Freemarker templates
In this release, the server will render the update profile page when the user is authenticating through a broker for the
first time using the `idp-review-user-profile.ftl` template.
In previous releases, the template used to update the profile during the first broker login flow was the `login-update-profile.ftl`, the same used
to update profile when users are authenticating to a realm.
By using separate templates for each flow, a more clear distinction exist as to which flow a template is actually used rather than sharing a same template,
and potentially introduce unexpected changes and behavior that should only affect pages for a specific flow.
If you have customizations to the `login-update-profile.ftl` template to customize how users update their profiles when authenticating through a broker, make sure to move your changes
= Sequential loading of offline sessions and remote sessions
Starting with this release, the first member of a Keycloak cluster will load remote sessions sequentially instead of in parallel.
If offline session preloading is enabled, those will be loaded sequentially as well.
The previous code led to high resource-consumption across the cluster at startup and was challenging to analyze in production environments and could lead to complex failure scenarios if a node was restarted during loading.
Therefore, it was changed to sequential session loading.
For offline sessions, the default in this and previous versions of Keycloak is to load those sessions on demand, which scales better with a lot of offline sessions than the attempt to preload them in parallel. Setups that use this default setup are not affected by the change of the loading strategy for offline sessions.
Setups that have offline session preloading enabled should migrate to a setup where offline-session preloading is disabled.
The default behavior of Keycloak is to load offline sessions on demand.
The old behavior to preload them at startup is now deprecated, as preloading them at startup does not scale well with a growing number of sessions, and increases Keycloak memory usage.
The old behavior will be removed in a future release.
To re-enable old behavior while it is deprecated and not removed yet, use the feature flag and the SPI option as shown below:
The API of `UserSessionProvider` deprecated the method `getOfflineUserSessionByBrokerSessionId(RealmModel realm, String brokerSessionId)`.
Instead of this method, use `getOfflineUserSessionByBrokerUserIdStream(RealmModel, String brokerUserId)` to first get the sessions of a user, and then filter by the broker session ID as needed.
= The Admin send-verify-email API now uses the same email verification template
----
PUT /admin/realms/{realm}/users/{id}/send-verify-email
----
In this release, the API will use the `email-verification.ftl` template instead of `executeActions.ftl`.
.Before upgrading
----
Perform the following action(s): Verify Email
----
.After upgrading
----
Confirm validity of e-mail address email@example.org.
----
If you have customized the `executeActions.ftl` template to modify how users verify their email using this API, ensure that you transfer your modifications to the new template.
A new parameter called `lifespan` will be introduced to allow overriding of the default lifespan value (12 hours).
If you prefer the previous behavior, use the `execute-actions-email` API as follows.
----
PUT /admin/realms/{realm}/users/{id}/execute-actions-email
= Removal of the deprecated mode for SAML encryption
The compatibility mode for SAML encryption introduced in version 21 is now removed. The system property `keycloak.saml.deprecated.encryption` is not managed anymore by the server. The clients which still used the old signing key for encryption should update it from the new IDP configuration metadata.
In this release we adapted the password hashing defaults to match the https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html#pbkdf2[OWASP recommendations for Password Storage].
As part of this change, the default password hashing provider has changed from `pbkdf2-sha256` to `pbkdf2-sha512`.
Also, the number of default hash iterations for `pbkdf2` based password hashing algorithms changed as follows:
[%autowidth,cols="a,a,>a,>a"]
|===
| Provider ID | Algorithm | Old Iterations | New Iterations
If a realm does not explicitly configure a password policy with `hashAlgorithm` and `hashIterations`, then
the new configuration will take effect on the next password based login, or when a user password is created or updated.
== Performance of new password hashing configuration
Tests on a machine with an Intel i9-8950HK CPU (12) @ 4.800GHz yielded the following ⌀ time differences for hashing 1000 passwords (averages from 3 runs).
Note that the average duration for the `PBKDF2WithHmacSHA1` was computed with a lower number of passwords due to the long runtime.
[%autowidth,cols="a,a,>a,>a,>a"]
|===
| Provider ID | Algorithm | Old duration | New duration | Difference
== Expected increased overall CPU usage and temporary increased database activity
The Concepts for sizing CPU and memory resources in the Keycloak High Availability guide have been updated to reflect the new hashing defaults.
While the CPU usage per password-based login in our tests increased by 33% (which includes both the changed password hashing and unchanged TLS connection handling), the overall CPU increase should be around 10% to 15%.
This is due to the averaging effect of Keycloak's other activities like refreshing access tokens and client credential grants, still this depends on the unique workload of an installation.
After the upgrade, during a password-based login, the user's passwords will be re-hashed with the new hash algorithm and hash iterations as a one-off activity and updated in the database.
As this clears the user from Keycloak's internal cache, you'll also see an increased read activity on the database level.
This increased database activity will decrease over time as more and more user's passwords have been re-hashed.
Secrets and ConfigMaps referenced via the Keycloak CR will now be polled for changes, rather than watched via the api server. It may take around 1 minute for changes to be detected.
This was done so to not require label manipulation on those resources. After upgrading if any Secret still has the operator.keycloak.org/component label, it may be removed or ignored.
and `org.keycloak:keycloak-model-legacy` module was deprecated and will be removed in the next release in favour of `org.keycloak:keycloak-model-storage` module.
