[SL] After upgrade to 2.8.20 payments are automatically posted to recurring invoices

[Craig I. <cr...@da...>]

Hi Everyone,

We upgraded from 2.8.17 to 2.8.20 last night, everything seemed fine.  Today
we processed recurring invoices and discovered shortly thereafter that all
(see below for exceptions) of the recurring invoices automatically posted a
payment to each one!  The system went back in time (2005, 2006, 2007 and 2008)
and grabbed a previous client payment then posted it to this new invoice.

The only exceptions we have noticed so far are:
  - Recurring transactions that were new (i.e. recently created)
  - Invoices posted by hand (i.e. they were not a recurring invoice)

The system has been solid and stable until this upgrade.  Any thoughts on how
we can prevent this from happing again in the future are welcome.
