Although XF 2 is still a while away, I have updated the terms of the license to indicate that the initial license purchase provides 12 months of support and updates.
After that time, in order to download new versions or receive support, an annual renewal fee of £15 will have to be paid, on an ongoing basis.
However, that will only come into effect when it is rewritten for XF2.
At that time, development and support for the XF1 version will cease and regardless of when you purchased (or do purchase) the XF1 version, it will be necessary to purchase the renewal in order to update each license you hold to the XF2 version.
So if you purchased 2 years ago or you purchase now and XF2 comes out in 6 months, the fee will have to be paid.
I anticipate some of you may not be happy with the move to an annual renewal fee but I have provided free upgrades and support for the past two years and as a complete rewrite will be required for XF2, I can't justify the amount of work required without some form of recompense.
Essentially it just means existing license holders will only have to pay £15 for the XF2 version of the add-on, rather than full price.
