[Zhang, B. <bin...@sa...>]

Hello QuantLib contributors,
Thanks for the great work!
Is there a change log that describe the new functionalities in QLXL 1.20 compared to previous version?

Dear Jack,

Not all QuantLib functionality has been exported to QuantLibXL.  I would describe my efforts as mantainer as hovering around the level of barely keeping the project alive.  I aim to get a 1.20 release out.  I do merge the pull requests that I receive.

Kind Regards,
Eric

Dear Eric and QuantLibXL users,

I've been experimenting with QuantLibXL a little bit recently and had a couple of questions regarding it...

1) the qlGeneralizedBlackScholesProcess() class seems to only accept doubles for the rate and dividend arguments (as opposed to termstructures in QL)*

2) I can't see any other spot/vol processes (eg. Heston) implemented in the wrapper yet

I'm not a heavy excel user but my use-case here is that it's quite nice as a demonstration aid to have excel in one window and the C++/Python in another if the API is consistent to show how you build the same items in each.

Is the add-on being actively worked on at the moment? Are pull requests being merged, and is the correct repo the one below?

Thanks,
Jack

Hi All,

In the coming days I will respond to all of the outstanding pull
requests and queries that I have received, and then I will produce a
final release candidate.

Kind Regards,
