Expiry date of .swz signatures supplied in the flex 4.6 SDK

Hello,

Lots of issue happened on May 5 when the .swz signature for flex 4.1 got expired for the Web sites which are using .swz file. So, to avoid that and to be prepared for that, Can you please share the planned expire date of .swz signatures supplied in the flex 4.6 SDK.?

Thanks in advance.

Thanks & Regards,

Akshay.
