If you are installing CiviCRM 4.7 from scratch, please use the corresponding automated installer instructions:
Authorize.net users:: Prior to 4.7, CiviCRM forced Authorize.net to send out receipt emails regardless of Authorize.net configuration. From 4.7 onwards this will not happen and you should log into your Authorize.net interface and configure whether you want Authorize.net to send out receipts (in addition to those sent by CiviCRM).
Lybunt report users:: Some fields that were previously mandatory on Lybunt are now optional. On new reports they are on by default but you might need to check the fields you want are selected for existing reports.
UPGRADING TO 4.7
If your site is highly customized with special code or theming for CiviCRM you will want to upgrade a test copy first and test your customizations. For everyone else, follow these simple steps to get yourself up and running with 4.7.
