---------------------------------------------

* Fixed a regression introduced in version 1.6.56 that caused `png_get_PLTE`
|

to return stale palette data after applying gamma and background transforms
|
||||
in-place.
|
||||
(Reported by ralfjunker <ralfjunker@users.noreply.github.com>.)
|
||||
* Fixed CVE-2026-46675 (medium severity):
|
||||
Use-after-free of zlib input in `png_read_end` after incomplete zTXt, iTXt
|
||||
or iCCP decompression.
|
||||
(Reported independently by Ze Sheng and
|
||||
<JasonHonKL@users.noreply.github.com>.)
|
||||
* Fixed a regression introduced in version 1.6.47 that caused libpng to reject
|
||||
hIST chunks in their correct position, after PLTE.
|
||||
(Contributed by Yuki Sekiguchi.)
|
||||
* Prevented a double free of `png_struct` members after an allocation failure.
|
||||
(Contributed by Anthony Hurtado.)
|
||||
* Applied fixes and updates to the CMake build.
|
||||
* Adopted the REUSE Specification for licensing the CI files.
