+  Removed the Travis CI configuration files, with heartfelt thanks for
+    their generous support of our project over the past five years!
+
+Version 1.6.49 [June 12, 2025]
+  Added SIMD-optimized code for the RISC-V Vector Extension (RVV).
+    (Contributed by Manfred Schlaegl, Dragos Tiselice and Filip Wasil)
+  Added various fixes and improvements to the build scripts and to
+    the sample code.
+
+Version 1.6.50 [July 1, 2025]
+  Improved the detection of the RVV Extension on the RISC-V platform.
+    (Contributed by Filip Wasil)
+  Replaced inline ASM with C intrinsics in the RVV code.

+  Fixed a decoder defect in which unknown chunks trailing IDAT, set
+    to go through the unknown chunk handler, incorrectly triggered
+    out-of-place IEND errors.
+    (Contributed by John Bowler)
+  Fixed the CMake file for cross-platform builds that require `libm`.
+
+Version 1.6.51 [November 21, 2025]

+    Heap buffer overflow in `png_do_quantize` via malformed palette index.
+    (Reported by Samsung; analyzed by Fabio Gritti.)
+  Fixed CVE-2025-64506 (moderate severity):
+    Heap buffer over-read in `png_write_image_8bit` with 8-bit input and
+    `convert_to_8bit` enabled.
+    (Reported by Samsung and <[email protected]>;
+    analyzed by Fabio Gritti.)
+  Fixed CVE-2025-64720 (high severity):
+    Buffer overflow in `png_image_read_composite` via incorrect palette
+    premultiplication.
+    (Reported by Samsung; analyzed by John Bowler.)

+  Fixed a memory leak in `png_set_quantize`.
+    (Reported by Samsung; analyzed by Fabio Gritti.)
+  Removed the experimental and incomplete ERROR_NUMBERS code.
+    (Contributed by Tobias Stoeckmann.)
+  Improved the RISC-V vector extension support; required RVV 1.0 or newer.
+    (Contributed by Filip Wasil.)
+  Added GitHub Actions workflows for automated testing.
