h3. Centralized (LoginCluster) federation
-If all clusters belong to the same organization, and users in that organization should have access to all the clusters, user management can be simplified by setting the @LoginCluster@ which manages the user database used by all other clusters in the federation. To do this, choose one cluster in the federation which will be the 'login cluster'. Set the the @Login.LoginCluster@ configuration value on all clusters in the federation to the cluster id of the login cluster. After setting @LoginCluster@, restart arvados-api-server and arvados-controller.

Clusters:
The @preserve_version@ attribute on collections was originally designed to allow clients to persist a preexisting collection version. This forced clients to make 2 requests if the intention is to "make this set of changes in a new version that will be kept", so we have changed the semantics to do just that: When passing @preserve_version=true@ along with other collection updates, the current version is persisted and also the newly created one will be persisted on the next update.
+h3. System token requirements
+
+System services now log a warning at startup if any of the system tokens (@ManagementToken@, @SystemRootToken@, and @Collections.BlobSigningKey@) are less than 32 characters, or contain characters other than a-z, A-Z, and 0-9. After upgrading, run @arvados-server config-check@ and update your configuration file if needed to resolve any warnings.
+
+The @API.RailsSessionSecretToken@ configuration key has been removed. Delete this entry from your configuration file after upgrading.

h3. Centos7 Python 3 dependency upgraded to python3
Now that Python 3 is part of the base repository in CentOS 7, the Python 3 dependency for Centos7 Arvados packages was changed from SCL rh-python36 to python3.
h2. Workbench examples
-Many Arvados Workbench pages, under the the *Advanced* tab, provide examples of API and SDK use for accessing the current resource .

These secret tokens are used to authenticate messages between Arvados components.
* @SystemRootToken@ is used by Arvados system services to authenticate as the system (root) user when communicating with the API server.
* @ManagementToken@ is used to authenticate access to system metrics.
-* @API.RailsSessionSecretToken@ is used to sign session cookies.
* @Collections.BlobSigningKey@ is used to control access to Keep blocks.
Each token should be a string of at least 50 alphanumeric characters. You can generate a suitable token with the following command:
h3. Collections download URL
-Downloads links will served from the the URL in @Services.WebDAVDownload.ExternalURL@ . The collection uuid or PDH is put in the URL path.
+Downloads links will served from the URL in @Services.WebDAVDownload.ExternalURL@ . The collection uuid or PDH is put in the URL path.
If blank, serve links to WebDAV with @disposition=attachment@ query param. Unlike preview links, browsers do not render attachments, so there is no risk of XSS.
