+ graphicsmagick (1.4+really1.3.37+hg16662-1) unstable; urgency=medium
+ 
+   * Mercurial snapshot, fixing the following security issues:
+     - ReadMATImageV4(): change 'ldblk' to size_t and check related
+       calculations for overflow and to avoid possible negative seek offsets,
+     - ReadMATImage(): change 'ldblk' to size_t and check related calculations
+       for overflow and to avoid possible negative seek offsets,
+     - added a ReadResource limit via the MAGICK_LIMIT_READ environment
+       variable on how many uncompressed file bytes may be read while decoding
+       an input file,
+     - DecodeImage(): assure that the claimed scanline length is within the
+       bounds of the scanline allocation to avoid possible heap overflow,
+     - ReadBlob(): fix EOF logic, an use-of-uninitialized-value in
+       SyncImageCallBack,
+     - ReadBlobStream(): fix EOF logic, an use-of-uninitialized-value in
+       WritePNMImage.
+   * Build with HEIF image format support.
+   * Update library symbols for this release.
