 Imager release history.  Older releases can be found in Changes.old
 
+Coverity finally finished a build, fix a few problems:
+
+ - reading a color-mapped TGA file with an id string would cause a
+   double-free if the palette was truncated.
+
+ - mixing scaling to sizes where the accumulator row, the working
+   output row or the working input row didn't fit into the address
+   space could result in memory leaks.  This can probably only be
+   reproduced on very wide floating-point sample images.
+
+ - convert an array style function parameter pointer to pointer style
+   to prevent confusing Coverity in the T1 bounding box implementation.
+
+ - Similarly in the FT1 bounding box implementation.
+
+ - initialize a pointer to prevent Coverity complaining in polygon
+   drawing (it should always end up being set.)
+
+ - addi style makemap could potentially read one past the end of an
+   array.
+
+ - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
+   would result in read beyond the end of the built-in hatch array.
+   Negative values (which Coverity didn't complain about) could also
+   cause problems.
+
+ - the Imager::Color set_internal() interal method no longer
+   calls the over-complicated ICL_set_internal() (which is retained
+   only for the old API.)  Coverity complained that this leaked, but
+   this could only occur with an invalid (NULL pointer) color object.
+
+ - the underlying implementation of the map() method could read before
+   the beginning on an allocated array if supplied with inconsistent
+   parameters, which Coverity complained about.  No Imager code calls
+   that function with inconsistent parameters, but a
+   belt-and-suspenders check was added.
+
+ - Coverity complained a call to i_getcolors(), used by the
+   implementation of the is_bilevel() method could leave the fetched
+   colors uninitialized.  Added a return value check.
+
+Imager 1.008 - 31 Dec 2018
+============
+
+ - moved EXIF handling from Imager::File::JPEG to core Imager
+   This allows file formats that store EXIF data as blobs similarly
+   to JPEG to re-use this code. (such as Imager::File::WEBP)
+
+ - added some more file extensions to image file type mappings
+
+ - added add_type_extensions() class method
+
+Imager 1.007 - 24 Nov 2018
+============
+
  - add png_compression_level tag for writing PNG files.
 
  - avoid flooring a second time in matrix transform interpolation.

+ - produce v2 metadata.
+   Includes change from the ticket and updates to sub-modules.
+   https://rt.cpan.org/Ticket/Display.html?id=127216
+
+ - improve error reporting for the polygon() method
