 +h3. Removing sso-provider
 +
 +The SSO (single sign-on) component is deprecated and will not be supported in future releases. Existing configurations will continue to work in this release, but you should switch to one of the built-in authentication mechanisms as soon as possible. See "setting up web based login":{{site.baseurl}}/install/setup-login.html for details.
 +
 +After migrating your configuration, uninstall the @arvados-sso-provider@ package.
  
+ h3. S3 signatures
+ 
+ Keepstore now uses "V4 signatures":https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html by default for S3 requests. If you are using Amazon S3, no action is needed; all regions support V4 signatures. If you are using a different S3-compatible service that does not support V4 signatures, add @V2Signature: true@ to your volume driver parameters to preserve the old behavior. See "configuring S3 object storage":{{site.baseurl}}/install/configure-s3-object-storage.html.
