[Elecraft] K3 KFL3B-FM Change?

[Joe Subich, W4TV]

In the past day or two I have noticed a change on the K3 order page. 
The KFL3B-FM was previously listed as a 7-pole filter at $99.00.  
It is now listed as an 8-pole filter at $120.00. 

Is this an "error correction" or a change in the specifications?  If 
this is a change in the specifications, does this indicate data is  
available for the "new" version and does this represent an improvement 
in skirt selectivity and ultimate rejection such that the KFL3B-FM 
can be used successfully for both AM/ESSB transmit and receive?  

How does this change effect those who have previously placed orders 
that included the KFL3B-FM? 

73,
