Original Comment:
I have used this add-on before, but now that I am using 70.0b2 (32-bit) it is not compatible.

May I ask when the next stable release for TB 70.x may be?

Thank you.

This review is for a previous version of the add-on (4.0.4). 

I will be releasing a point revision addressing an index issue. Probably within a few days. It's only a control on the max version, my basic testing shows still compatible with seventy.
we should be able to change the extensions.strict option to false but that seems to not work now.
You can download the. I just posted that removes the max for restriction.
