As we all know, there is some issue in security patch SUPEE 8788, so magento has released its new security patch SUPEE 8788 v2. I am wondering there is anything new for the after magento 1.8 or it is the patch for previous versions.

And also want to know what could be possible error and what precaution we need to take care before installing this patch?

SUPEE 8788 V2 fixes the following problems introduced by SUPEE 8788 V1:

  • conflict with 1533 patch
  • conflict with 3941 patch
  • Unsupported data type N error in /lib/Unserialize/Reader/ArrValue.php in and possibly earlier versions

If you apply the patch V2 don't forget to follow this procedure:

  • revert SUPEE-8788 v1
  • revert SUPEE-1533 (if installed)
  • install SUPEE-3941 (if not installed)
  • install SUPEE-8788 v2
  • 2
    Addition: if you managed to install v1 on 1.9.2 and solved the conflicts yourself, you don't need v2 Commented Oct 17, 2016 at 8:36
  • @fschmengler the v1 does not address the Unsupported data type N error so if you haven't created the lib files manually you still need to apply v2 Commented Oct 17, 2016 at 11:45

    Wasn't that only a problem with versions up to 1.9.1? I need to double check but don't think we had problems with our 1.9.2 installations Commented Oct 17, 2016 at 11:46
  • @fschmengler sorry misread instead of 1.9.2 Commented Oct 17, 2016 at 11:48
