Vault tagging	S3 Glacier now allows you to tag your S3 Glacier vaults for easier resource and cost management. Tags are labels that you can define and associate with your vaults, and using tags adds filtering capabilities to operations such as AWS cost reports. For more information, see Tagging Amazon S3 Glacier Resources and Tagging Your S3 Glacier Vaults.	June 22, 2015
Vault access policies	S3 Glacier now supports managing access to your individual S3 Glacier vaults by using vault access policies. You can now define an access policy directly on a vault, making it easier to grant vault access to users and business groups internal to your organization, as well as to your external business partners. For more information, see Vault Access Policies.	April 27, 2015
Data retrieval policies and audit logging	S3 Glacier now supports data retrieval policies and audit logging. Data retrieval policies allow you to easily set data retrieval limits and simplify data retrieval cost management. You can define your own data retrieval limits with a few clicks in the AWS Management Console or by using the S3 Glacier API. For more information, see S3 Glacier Data Retrieval Policies. In addition, S3 Glacier now supports audit logging with AWS CloudTrail, which records S3 Glacier API calls for your account and delivers the log files to an Amazon S3 bucket that you specify. For more information, see Logging Amazon S3 Glacier API Calls with AWS CloudTrail.	December 11, 2014
Updates to Java samples	Updated the Java code examples in this guide that use the AWS SDK for Java.	June 27, 2014
Limiting vault inventory retrieval	You can now limit the number of vault inventory items retrieved by filtering on the archive creation date or by setting a limit.

Removed outdated URLs	Removed the URLs that pointed to the old security credentials page from code examples.	July 26, 2013
Support for range retrievals	S3 Glacier now supports retrieval of specific ranges of your archives. You can initiate a job requesting S3 Glacier to prepare an entire archive or a portion of the archive for subsequent download. When an archive is very large, you may find it cost effective to initiate several sequential jobs to prepare your archive. For more information, see Downloading an Archive in S3 Glacier.
