+h3. Storage classes must be defined explicitly
+
+If your configuration uses the StorageClasses attribute on any Keep volumes, you must add a new @StorageClasses@ section that lists all of your storage classes. Refer to the updated documentation about "configuring storage classes":{{site.baseurl}}/admin/storage-classes.html for details.

 h3. keep-balance requires access to PostgreSQL
 
 Make sure the keep-balance process can connect to your PostgreSQL server using the settings in your config file. (In previous versions, keep-balance accessed the database through controller instead of connecting to the database server directly.)

 The @crunch-dispatch-local@ dispatcher now reads the API host and token from the system wide @/etc/arvados/config.yml@ .  It will fail to start that file is not found or not readable.

 h3. Multi-file docker image collections
 
 Typically a docker image collection contains a single @.tar@ file at the top level. Handling of atypical cases has changed. If a docker image collection contains files with extensions other than @.tar@, they will be ignored (previously they could cause errors). If a docker image collection contains multiple @.tar@ files, it will cause an error at runtime, "cannot choose from multiple tar files in image collection" (previously one of the @.tar@ files was selected). Subdirectories are ignored. The @arv keep docker@ command always creates a collection with a single @.tar@ file, and never uses subdirectories, so this change will not affect most users.

 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.
