+h3. Remove Workbench1 packages after upgrading the salt installer
+
+If you have an Arvados cluster deployed with a previous version of the installer and you're planning on upgrading the installer, please take into consideration that the already installed workbench1 package will need to be uninstalled manually from the workbench instance.
+
+h3. Remove Workbench1 packages and configuration
+
+The Workbench1 application has been removed from the Arvados distribution. We recommend the following follow-up steps.
+* Remove the Workbench1 package from any service node where it is installed (e.g., @apt remove arvados-workbench@).
+* In your Nginx configuration, add your Workbench1 URL host (from @Services.Workbench1.ExternalURL@) to the @server_name@ directive in the Workbench2 section. For example: <notextile><pre>server {
+ listen 443 ssl;
+ server_name workbench.ClusterID.example.com workbench2.ClusterID.example.com;
+ ...
+}</pre></notextile>
+* In your Nginx configuration, remove the @upstream@ and @server@ sections for Workbench1.
+* Remove the @Services.Workbench1.InternalURLs@ section of your configuration file. (Do not remove @ExternalURL@.)
+* Run @arvados-server config-check@ to identify any Workbench1-specific entries in your configuration file, and remove them.
+
+h3. Check implications of Containers.MaximumPriceFactor 1.5
+
+When scheduling a container, Arvados now considers using instance types other than the lowest-cost type consistent with the container's resource constraints. If a larger instance is already running and idle, or the cloud provider reports that the optimal instance type is not currently available, Arvados will select a larger instance type, provided the cost does not exceed 1.5x the optimal instance type cost.
+
+This will typically reduce overall latency for containers and reduce instance booting/shutdown overhead, but may increase costs depending on workload and instance availability. To avoid this behavior, configure @Containers.MaximumPriceFactor: 1.0@.
+
+h3. Synchronize keepstore and keep-balance upgrades
+
+The internal communication between keepstore and keep-balance about read-only volumes has changed. After keep-balance is upgraded, old versions of keepstore will be treated as read-only. We recommend upgrading and restarting all keepstore services first, then upgrading and restarting keep-balance.
+
+h3. Separate configs for MaxConcurrentRequests and MaxConcurrentRailsRequests
+
+The default configuration value @API.MaxConcurrentRequests@ (the number of concurrent requests that will be processed by a single instance of an arvados service process) is raised from 8 to 64.
+
+A new configuration key @API.MaxConcurrentRailsRequests@ (default 8) limits the number of concurrent requests processed by a RailsAPI service process.
