The series originally ended in 1987 with #6 and was restarted in 2007 with #38.
To get to #38, Heroic Publishing is using the following series in the count:
6 issues - Champions (1986)
12 issues - Champions (1987)
1 issues - Champions Classics
11 issues - Champions/Flare Adventures
3 issues - Champions Classics
4 issues - Tales of the Champions
Parent company Heroic Publishing has ceased publishing three times in its history. First from early 1989 to late 1990. Second, and most lengthy, from early 1994 to 2003. Third from late 2007 to early 2009.
As such, #38 & 39 of this series were published in 2007, while #40 - Current were published since 2009.
Issues published since 2009 are published print-on-demand as Heroic Publishing no longer meets Diamond's minimum threshold for distribution.
