+2.1.5
+=====
+
+### Significant changes relative to 2.1.4:
+
+1. Fixed issues in the build system whereby, when using the Ninja Multi-Config
+CMake generator, a static build of libjpeg-turbo (a build in which
+`ENABLE_SHARED` is `0`) could not be installed, a Windows installer could not
+be built, and the Java regression tests failed.
+
+2. Fixed a regression introduced by 2.0 beta1[15] that caused a buffer overrun
+in the progressive Huffman encoder when attempting to transform a
+specially-crafted malformed 12-bit-per-component JPEG image into a progressive
+12-bit-per-component JPEG image using a 12-bit-per-component build of
+libjpeg-turbo (`-DWITH_12BIT=1`.) Given that the buffer overrun was fully
+contained within the progressive Huffman encoder structure and did not cause a
+segfault or other user-visible errant behavior, given that the lossless
+transformer (unlike the decompressor) is not generally exposed to arbitrary
+data exploits, and given that 12-bit-per-component builds of libjpeg-turbo are
+uncommon, this issue did not likely pose a security risk.
+
+3. Fixed an issue whereby, when using a 12-bit-per-component build of
+libjpeg-turbo (`-DWITH_12BIT=1`), passing samples with values greater than 4095
+or less than 0 to `jpeg_write_scanlines()` caused a buffer overrun or underrun
+in the RGB-to-YCbCr color converter.
+
+4. Fixed a floating point exception that occurred when attempting to use the
+jpegtran `-drop` and `-trim` options to losslessly transform a
+specially-crafted malformed JPEG image.
+
+5. Fixed an issue in `tjBufSizeYUV2()` whereby it returned a bogus result,
+rather than throwing an error, if the `align` parameter was not a power of 2.
+Fixed a similar issue in `tjCompressFromYUV()` whereby it generated a corrupt
+JPEG image in certain cases, rather than throwing an error, if the `align`
+parameter was not a power of 2.
+
+6. Fixed an issue whereby `tjDecompressToYUV2()`, which is a wrapper for
+`tjDecompressToYUVPlanes()`, used the desired YUV image dimensions rather than
+the actual scaled image dimensions when computing the plane pointers and
+strides to pass to `tjDecompressToYUVPlanes()`. This caused a buffer overrun
+and subsequent segfault if the desired image dimensions exceeded the scaled
+image dimensions.
+
+7. Fixed an issue whereby, when decompressing a 12-bit-per-component JPEG image
+(`-DWITH_12BIT=1`) using an alpha-enabled output color space such as
+`JCS_EXT_RGBA`, the alpha channel was set to 255 rather than 4095.
+
+8. Fixed an issue whereby the Java version of TJBench did not accept a range of
+quality values.
+
+9. Fixed an issue whereby, when `-progressive` was passed to TJBench, the JPEG
+input image was not transformed into a progressive JPEG image prior to
+decompression.
