The Unit Price column now shows up with four decimal places (e.g. "$100.0000") instead of two ("$100.00"). The Quantity and Total columns are unaffected. This is with the Fancy Invoice stylesheet to which I have applied non-default settings. Invoices that existed prior to the upgrade, posted or not, exhibit the same behavior.

I intend to dig into my settings and read the release notes more closely to see if this is a "me" problem. Please feel free to point me in the right direction in the mean time, if you know more than I do. If I cannot solve this on my own, I will be glad to prepare a ticket.

Thank you for that explanation. I'm not sure I understand it fully, but 
at least I grasp that the "Decimal places" setting is irrelevant to this 
display anomaly that is new for me in 5.12.

If I want the old display behavior back, where all currency columns in 
the Fancy Invoice report render precision to USD pennies ($0.01), no 
more and no less, what should I try adjusting next? That is, I have no 
need to display prices with more than penny precision, and doing so 
unnecessarily is likely to cause confusion among my customers.
