= Legacy Promise API removed from Keycloak JS adapter
The legacy Promise API methods have been removed from the Keycloak JS adapter. This means that calling `.success()` and `.error()` on promises returned from the adapter is no longer possible. Instead standardized Promise methods such as https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then[`.then()`] and https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch[`.catch()`] should be used.
.Or alternatively, when using the https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/await[`await`] keyword to unwrap these promises:
In previous releases, the `export` and `import` commands required a `build` command to be run first.
Starting with this release, the `export` and `import` commands perform an automatic rebuild of Keycloak if a build time configuration has changed.
When migrating existing scripts that run a `build` command first, migrate by adding the `--optimized` command line option to the `export` and `import` command to avoid Keycloak automatically re-building the image.
Not adding the `--optimized` option in this might make Keycloak trigger a rebuild and revert to the default values, and then connecting to the database for export and import will not work.
The following examples assume that runtime parameters like a database password are provided via a configuration file or an environment variable.
.Before migration: Running the build command before running the export command
[source,bash]
----
bin/kc.[sh|bat] build --db=postgres ...
bin/kc.[sh|bat] export --dir <dir>
----
.After migration: Adding `--optimized` to the export command
NOTE:: When the auto-build runs, the build time options will be in effect for all subsequent commands that are started with the `--optimized` flag, including the `start` command.
In previous releases the `export` and `import` commands allowed runtime parameters such as a database URL only in configuration files or environment variables.
After the upgrade to Jakarta EE, artifacts for Keycloak Admin clients were renamed to more descriptive names with consideration for long-term maintainability.
We still provide two separate Keycloak Admin clients, one with Jakarta EE and the other with Java EE support.
We stopped releasing the `org.keycloak:keycloak-admin-client-jakarta` artifact.
The default one for the Keycloak Admin client with Jakarta EE support is `org.keycloak:keycloak-admin-client` (since version 22.0.0).
We will continue to release the Keycloak Admin client with Java EE support for some time, but we recommend that you migrate to Jakarta EE as soon as possible.
The new artifact with Java EE support is `org.keycloak:keycloak-admin-client-jee`.
