+h3. New spelling of S3 credential configs
+
+If you use the S3 driver for Keep volumes and specify credentials in your configuration file (as opposed to using an IAM role), you should change the spelling of the @AccessKey@ and @SecretKey@ config keys to @AccessKeyID@ and @SecretAccessKey@. If you don't update them, the previous spellings will still be accepted, but warnings will be logged at server startup.
+
+h3. New proxy parameters for arvados-controller
+
+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@).
+
+<pre>
+    proxy_set_header      Upgrade           $http_upgrade;
+    proxy_set_header      Connection        "upgrade";
+</pre>
+
+h3. Changes on the collection's @preserve_version@ attribute semantics
+
+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.
 
+h3. ForceLegacyAPI14 option removed
+
+The ForceLegacyAPI14 configuration option has been removed. In the unlikely event it is mentioned in your config file, remove it to avoid "deprecated/unknown config" warning logs.

 A satellite cluster that delegates its user login to a central user database must only have `Login.LoginCluster` set, or it will return an error.  This is a change in behavior, previously it would return an error if another login provider was _not_ configured, even though the provider would never be used.
 
+h3. Minimum supported Python version is now 3.5
+
+We no longer publish Python 2 based distribution packages for our Python components. There are equivalent packages based on Python 3, but their names are slightly different. If you were using the Python 2 based packages, you can install the Python 3 based package for a drop in replacement. On Debian and Ubuntu:

 h3. Minimum supported Ruby version is now 2.5
 
 The minimum supported Ruby version is now 2.5.  If you are running Arvados on Debian 9 or Ubuntu 16.04, you may need to switch to using RVM or upgrade your OS.  See "Install Ruby and Bundler":../install/ruby.html for more information.
