[Tiki-devel] Fwd: [TikiWiki-commits] [Git][tikiwiki/tiki][23.x] [ENH] add system currency exchange rates tracker preferences

Hello Tiki-devs,

Attn to those using Currency tracker field (Marc, Bernard, Jonny, not 
sure about others):

I have made a long-waited update to the field to move some of the 
guesswork to Tiki preferences. Added a new section 'System Trackers' in 
Control Panels -> Trackers -> bottom of the page. You can enable 
Exchange rates tracker, select which one it is, select the corresponding 
fields (Currency, Rate, Date) and also the conversion logic (if the 
rates are entered straight or reverse pairs). An important update here 
is removal of the Currency Tracker selection in the Currency field 
options. We no longer need or want to use that from the field properties 
as we have a system tracker now. The important part for those of you 
managing Currency fields is to go to Trackers settings page and 
configure the system tracker fields.

This update only affects master/23.x.

Regards,
Victor
