The Account Console v2 theme has been removed from {project_name}. This theme was deprecated in {project_name} 24 and replaced by the Account Console v3 theme. If you are still using this theme, you should migrate to the Account Console v3 theme.
= Upgrade to PatternFly 5
In {project_name} 24, the Welcome page is updated to use https://www.patternfly.org/[PatternFly 5], the latest version of the design system that underpins the user interface of {project_name}. In this release, the Admin Console and Account Console are also updated to use PatternFly 5. If you want to extend and customize the Admin Console and Account Console, review https://www.patternfly.org/get-started/upgrade/[the changes in PatternFly 5] and update your customizations accordingly.
To prevent excessive memory and CPU usage, the parallel computation of hashes by Argon2 is by default limited to the number of cores available to the JVM.
= Addressed 'You are already logged in' for expired authentication sessions
The Keycloak 23 release provided improvements for when a user is authenticated in parallel in multiple browser tabs. However, this improvement did not address the case when an authentication session
expired. Now for the case when user is already logged-in in one browser tab and an authentication session expired in other browser tabs, {project_name} is able to redirect back to the client
application with an OIDC/SAML error, so the client application can immediately retry authentication, which should usually automatically log in the application because of the SSO session. For more
details, see link:{adminguide_link}#_authentication-sessions[{adminguide_name} authentication sessions].
= Lightweight access token to be even more lightweight
In previous releases, the support for lightweight access token was added. In this release, we managed to remove even more built-in claims from the lightweight access token. The claims are added
by protocol mappers. Some of them affect even the regular access tokens or ID tokens as they were not strictly required by the OIDC specification.
* Claims `sub` and `auth_time` are added by protocol mappers now, which are configured by default on the new client scope `basic`, which is added automatically to all the clients. The claims are still added to the ID token and access token as before, but not to lightweight access token.
* Claim `nonce` is added only to the ID token now. It is not added to a regular access token or lightweight access token. For backwards compatibility, you can add this claim to an access token by protocol mapper, which needs to be explicitly configured.
* Claim `session_state` is not added to any token now. It is still possible to add it by protocol mapper if needed. There is still the other dedicated claim `sid` supported by the specification, which was available in previous versions as well and which has exactly the same value.

When searching for users by user attribute, {project_name} no longer searches for user attribute names forcing lower case comparisons. The goal of this change was to speed up searches by using {project_name}'s native index on the user attribute table. If your database collation is case-insensitive, your search results will stay the same. If your database collation is case-sensitive, you might see less search results than before.
This fix will break code that relied on casting the List or its contents to `List<Map>`. If you have used this method in any capacity, you are likely to have done this and be affected.
= IDs are no longer set when exporting authorization settings for a client
When exporting the authorization settings for a client, the IDs for resources, scopes, and policies are no longer set. As a
result, you can now import the settings from a client to another client.
