 Release 1.??.?? (??)
-intro text...
+Hard to believe it's been over a year since our last release, but it's
+not for lack of activity.  This release includes contributions of a wide
+assortment of bug fixes, build system improvements, warnings cleanups,
+codebase refactoring, test suite repairs, and static analysis work.
+This release is lighter on features (compared with 1.12.10) but includes
+a highly demanded rehaul of our image downscaling functionality, which
+solves a serious problem experienced by Inkscape users when shrinking
+embedded bitmaps in SVG files.

+    - CAIRO_FILTER_BEST: uses CATMULL filter always. Upscaling more than

   to now support scaling at a device level, permitting easier, more
