Magento Open Sourceis constantly evolving. New features are added and problems resolved on an ongoing basis. From time to time you will be notified that a new Magento CE version is available. This notice will be published in the Magento blog, and in your Admin InBox.

Consider the following before upgrading your store:

• 	If the update is critical, contains mandatory updates, or resolves issues that you have encountered, you should update your store.
  	Upgrading between major versions, such as between version 1.1 and 1.2, might require minor configuration changes. See the update release notes for more information.
  	If your store has a custom theme, you will benefit from the bug fixes in the update, but new the functionality might not be implemented in your theme.
  	We strongly recommend that you test all updates in a staging environment before upgrading a live store.
