+Imager 1.009 - 11 Jan 2019
+============
+
+Critical issue:
+
+ - drawing a filled, anti-aliased circle to the left or right of the
+   image (not within the image at all) would cause a buffer overflow.
+   https://rt.cpan.org/Ticket/Display.html?id=128208
+

 General changes:
 
  - to_paletted() and make_palette() now fail (with an error in
    errstr()) if invalid quantization parameters are supplied.

-Coverity finally finished a build[1], fix a few problems:
+ - map() would corrupt a channel if there was a gap in the arrayref of
+   channels.  Detected by Coverity.  CID 185300.
+
+ - most numeric parameters to the XS implementation now throw an
+   exception if supplied an unoverloaded reference.

+Coverity finally finished a build[1], fixed several of the problems
