[GNC] Next release of F::Q

[Eric Coates]

Hi

Apologies. It seems that my email system has developed a mind of its own 
and sent an early and incomplete version of this note.

I've been away for some time. Since returning I have not been able to 
find any information about an upgrade to Finance::Quote.

It seemed from the work done by Erik Colson and Chris Good that an 
update to version 1.47 (which I have installed) was within grasp. Is it 
expected to be released soon?

If not, is there a way that I (ignorant as I am) can in any way 
dupliacte Chris's work to get something working on my machine?

As always. many thanks to all who develop and support gnucash.

Eric
