+2.1.3
+=====
+
+### Significant changes relative to 2.1.2
+
+1. Fixed a regression introduced by 2.0 beta1[7] whereby cjpeg compressed PGM
+input files into full-color JPEG images unless the `-grayscale` option was
+used.
+
+2. cjpeg now automatically compresses GIF and 8-bit BMP input files into
+grayscale JPEG images if the input files contain only shades of gray.
+
+3. The build system now enables the intrinsics implementation of the AArch64
+(Arm 64-bit) Neon SIMD extensions by default when using GCC 12 or later.
+
+4. Fixed a segfault that occurred while decompressing a 4:2:0 JPEG image using
+the merged (non-fancy) upsampling algorithms (that is, with
+`cinfo.do_fancy_upsampling` set to `FALSE`) along with `jpeg_crop_scanline()`.
+Specifically, the segfault occurred if the number of bytes remaining in the
+output buffer was less than the number of bytes required to represent one
+uncropped scanline of the output image.  For that reason, the issue could only
+be reproduced using the libjpeg API, not using djpeg.

+2.1.2
+=====
+
+### Significant changes relative to 2.1.1
+
+1. Fixed a regression introduced by 2.1 beta1[13] that caused the remaining
+GAS implementations of AArch64 (Arm 64-bit) Neon SIMD functions (which are used
+by default with GCC for performance reasons) to be placed in the `.rodata`
+section rather than in the `.text` section.  This caused the GNU linker to
+automatically place the `.rodata` section in an executable segment, which
+prevented libjpeg-turbo from working properly with other linkers and also
+represented a potential security risk.
+
+2. Fixed an issue whereby the `tjTransform()` function incorrectly computed the
+MCU block size for 4:4:4 JPEG images with non-unary sampling factors and thus
+unduly rejected some cropping regions, even though those regions aligned with
+8x8 MCU block boundaries.
+
+3. Fixed a regression introduced by 2.1 beta1[13] that caused the build system
+to enable the Arm Neon SIMD extensions when targetting Armv6 and other legacy
+architectures that do not support Neon instructions.
+
+4. libjpeg-turbo now performs run-time detection of AltiVec instructions on
+FreeBSD/PowerPC systems if AltiVec instructions are not enabled at compile
+time.  This allows both AltiVec-equipped and non-AltiVec-equipped CPUs to be
+supported using the same build of libjpeg-turbo.
+
+5. cjpeg now accepts a `-strict` argument similar to that of djpeg and
+jpegtran, which causes the compressor to abort if an LZW-compressed GIF input
+image contains incomplete or corrupt image data.
