-h3. Anonymous token changes
+h3. Slurm dispatcher requires configuration update
-The anonymous token configured in @Users.AnonymousUserToken@ must now be 32 characters or longer. This was already the suggestion in the documentation, now it is enforced. The @script/get_anonymous_user_token.rb@ script that was needed to register the anonymous user token in the database has been removed. Registration of the anonymous token is no longer necessary. If the anonymous token in @config.yml@ is specified as a full V2 token, that will now generate a warning - it should be updated to list just the secret (i.e. the part after the last forward slash).
+If you use the Slurm dispatcher (@crunch-dispatch-slurm@) you must add a @Services.DispatchSLURM.InternalURLs@ section to your configuration file, as shown on the "updated install page":{{site.baseurl}}/install/crunch2-slurm/install-dispatch.html.
-h3. Preemptible instance types are used automatically, if any are configured
+h3. New proxy parameters for arvados-controller
-The default behavior for selecting "preemptible instances":{{site.baseurl}}/admin/spot-instances.html has changed. If your configuration lists any instance types with @Preemptible: true@, all child (non-top-level) containers will automatically be scheduled on preemptible instances. To avoid using preemptible instances except when explicitly requested by clients, add @AlwaysUsePreemptibleInstances: false@ in the @Containers@ config section. (Previously, preemptible instance types were never used unless the configuration specified @UsePreemptibleInstances: true@. That flag has been removed.)
+We now recommend disabling nginx proxy caching for arvados-controller, to avoid truncation of large responses.
-h3. Role groups are visible to all users by default
+In your Nginx configuration file (@/etc/nginx/conf.d/arvados-api-and-controller.conf@), add the following lines to the @location /@ block with @http://controller@ (see "Update nginx configuration":{{site.baseurl}}/install/install-api-server.html#update-nginx for an example) and reload/restart Nginx (@sudo nginx -s reload@).
-The permission model has changed such that all role groups are visible to all active users. This enables users to share objects with groups they don't belong to. To preserve the previous behavior, where role groups are only visible to members and admins, add @RoleGroupsVisibleToAll: false@ to the @Users@ section of your configuration file.

+h3. Now recommending Singularity 3.9.9
+
+The compute image "build script":{{site.baseurl}}/install/crunch2-cloud/install-compute-node.html now installs Singularity 3.9.9 instead of 3.7.4. The newer version includes a bugfix that should resolve "intermittent loopback device errors":https://dev.arvados.org/issues/18489 when running containers.
+
+h3. Changes to @arvados-cwl-runner --create-workflow@ and @--update-workflow@
+
+When using @arvados-cwl-runner --create-workflow@ or @--update-workflow@, by default it will now make a copy of all collection and Docker image dependencies in the target project. Running workflows retains the old behavior (use the dependencies wherever they are found). The can be controlled explicit with @--copy-deps@ and @--no-copy-deps@.

+
+"previous: Upgrading to 2.3.1":#v2_3_1
+
+h3. Default result order changed
+
+When requesting a list of objects without an explicit @order@ parameter, the default order has changed from @modified_at desc, uuid asc@ to @modified_at desc, uuid desc@. This means that if two objects have identical @modified_at@ timestamps, the tiebreaker will now be based on @uuid@ in decending order where previously it would be ascending order. The practical effect of this should be minor; with microsecond precision it is unusual to have two records with exactly the same timestamp, and order-sensitive queries should already provide an explicit @order@ parameter.
+
+h3. Ubuntu 18.04 Arvados Python packages now depend on python-3.8
+
+Ubuntu 18.04 ships with Python 3.6 as the default version of Python 3. Ubuntu also ships a version of Python 3.8, and the Arvados Python packages (@python3-arvados-cwl-runner@, @python3-arvados-fuse@, @python3-arvados-python-client@, @python3-arvados-user-activity@ and @python3-crunchstat-summary@) now depend on the @python-3.8@ system package.
+
+This means that they are now installed under @/usr/share/python3.8@ (before, the path was @/usr/share/python3@). If you rely on the @python3@ executable from the packages (e.g. to load a virtualenv), you may need to update the path to that executable.
+
+h3. Minimum supported Ruby version is now 2.6
+
+The minimum supported Ruby version is now 2.6. If you are running Arvados on Debian 10 or Ubuntu 18.04, you may need to switch to using RVM or upgrade your OS. See "Install Ruby and Bundler":../install/ruby.html for more information.
+
+h3. Anonymous token changes
+
+The anonymous token configured in @Users.AnonymousUserToken@ must now be 32 characters or longer. This was already the suggestion in the documentation, now it is enforced. The @script/get_anonymous_user_token.rb@ script that was needed to register the anonymous user token in the database has been removed. Registration of the anonymous token is no longer necessary.
+
+h3. Preemptible instance support changes
+
+The @Containers.UsePreemptibleInstances@ option has been renamed to @Containers.AlwaysUsePreemptibleInstances@ and has the same behavior when @true@ and one or more preemptible instances are configured. However, a value of @false@ no longer disables support for preemptible instances, instead users can now enable use of preemptible instances at the level of an individual workflow or workflow step.
+
+In addition, there is a new configuration option @Containers.PreemptiblePriceFactor@ will automatically add a preemptible instance type corresponding to each regular instance type. See "Using Preemptible instances":spot-instances.html for details.
h3. Default LSF arguments have changed
If you use LSF and your configuration specifies @Containers.LSF.BsubArgumentsList@, you should update it to include the new arguments (@"-R", "select[mem>=%MMB]", ...@, see "configuration reference":{{site.baseurl}}/admin/config.html). Otherwise, containers that are too big to run on any LSF host will remain in the LSF queue instead of being cancelled.
-h3. Previously trashed role groups will be deleted
+h3. Support for NVIDIA CUDA GPUs
-Due to a bug in previous versions, the @DELETE@ operation on a role group caused the group to be flagged as trash in the database, but continue to grant permissions regardless. After upgrading, any role groups that had been trashed this way will be deleted. This might surprise some users if they were relying on permissions that were still in effect due to this bug. Future @DELETE@ operations on a role group will immediately delete the group and revoke the associated permissions.
+Arvados now supports requesting NVIDIA CUDA GPUs for cloud and LSF (Slurm is currently not supported). To be able to request GPU nodes, some additional configuration is needed:
-h3. Users are visible to other users by default
+"Including GPU support in cloud compute node image":{{site.baseurl}}/install/crunch2-cloud/install-compute-node.html#nvidia
-When a new user is set up (either via @AutoSetupNewUsers@ config or via Workbench admin interface) the user immediately becomes visible to other users. To revert to the previous behavior, where the administrator must add two users to the same group using the Workbench admin interface in order for the users to see each other, change the new @Users.ActivatedUsersAreVisibleToOthers@ config to @false@.

+h3. Role groups are visible to all users by default
+
+The permission model has changed such that all role groups are visible to all active users. This enables users to share objects with groups they don't belong to. To preserve the previous behavior, where role groups are only visible to members and admins, add @RoleGroupsVisibleToAll: false@ to the @Users@ section of your configuration file.

h3. Dedicated keepstore process for each container
* If you already have a robust permanent keepstore infrastructure, you can set @Containers.LocalKeepBlobBuffersPerVCPU@ to 0 to disable this feature and preserve the previous behavior of sending container I/O traffic to your separately provisioned keepstore servers.
* This feature is enabled only if no volumes use @AccessViaHosts@, and no volumes have underlying @Replication@ less than @Collections.DefaultReplication@. If the feature is configured but cannot be enabled due to an incompatible volume configuration, this will be noted in the @crunch-run.txt@ file in the container log.

h3. Backend support for vocabulary checking
If your installation uses the vocabulary feature on Workbench2, you will need to update the cluster configuration by moving the vocabulary definition file to the node where @controller@ runs, and set the @API.VocabularyPath@ configuration parameter to the local path where the file was placed.
