You can either: a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs b) use the new bitbake-setup You can find information about either approach in our documentation: https://docs.yoctoproject.org/ Note that "poky" the distro setting is still available in meta-yocto as before and we continue to use and maintain that. Long live Poky! Some further information on the background of this change can be found in: https://lists.openembedded.org/g/openembedded-architecture/message/2179 Signed-off-by: Richard Purdie

libpng: upgrade 1.6.48 -> 1.6.50

2025-09-15T16:57:23+00:00

Changelog: 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. (Contributed by Filip Wasil) 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`.

libpng: Add ptest

2025-06-19T20:54:43+00:00

Install libpng test-suite to run it as a ptest. As the test-suite takes more than 30 seconds to run, add libpng-ptest to PTESTS_SLOW in ptest-packagelists.inc (From OE-Core rev: 8dca5305c950e6a06b3f344ffdbbb7386d802095) Signed-off-by: Poonam Jadhav Signed-off-by: Mathieu Dubois-Briand Signed-off-by: Richard Purdie

Changelog: ============ - Fixed the floating-point version of the mDCv setter 'png_set_mDCv'. - Added #error directives to discourage the inclusion of private libpng implementation header files in PNG-supporting applications. - Added the CMake build option 'PNG_LIBCONF_HEADER', to be used as an alternative to 'DFA_XTRA'. - Removed the Travis CI configuration files (From OE-Core rev: 521fb67a6ae80752c8d3cba1de0e4946e26f6c2f) Signed-off-by: Wang Mingyu Signed-off-by: Richard Purdie

libpng: upgrade 1.6.43 -> 1.6.44

2024-09-30T16:00:51+00:00

Changelog: =========== - Hardened calculations in chroma handling to prevent overflows, and relaxed a constraint in cHRM validation to accomodate the standard ACES AP1 set of color primaries. - Removed the ASM implementation of ARM Neon optimizations and updated the build accordingly. Only the remaining C implementation shall be used from now on, thus ensuring the support of the PAC/BTI security features on ARM64. - Fixed the pickup of the PNG_HARDWARE_OPTIMIZATIONS option in the CMake build on FreeBSD/amd64. This is an important performance fix on this platform. - Applied various fixes and improvements to the CMake build. - Added fuzzing targets for the simplified read API. - Fixed a build error involving pngtest.c under a custom config. - Fixed and improved the config files for AppVeyor CI and Travis CI.

libpng: upgrade 1.6.42 -> 1.6.43

2024-04-16T07:07:01+00:00

Changelog: =========== -Fixed the row width check in png_check_IHDR(). -Added eXIf chunk support to the push-mode reader in pngpread.c. -Added contrib/pngexif for the benefit of the users who would like to inspect the content of eXIf chunks. -Added contrib/conftest/basic.dfa, a basic build-time configuration. -Fixed a preprocessor condition in pngread.c that broke build-time configurations like contrib/conftest/pngcp.dfa. -Added CMake build support for LoongArch LSX. -Fixed a CMake build error that occurred under a peculiar state of the dependency tree. This was a regression introduced in libpng-1.6.41. -Marked the installed libpng headers as system headers in CMake. -Updated the build support for RISCOS. -Updated the makefiles to allow cross-platform builds to initialize conventional make variables like AR and ARFLAGS. -Added various improvements to the CI scripts in areas like version consistency verification and text linting. Added version consistency verification to pngtest.c also. (From OE-Core rev: d36edc338fde6879390c322fb6333812a2c2ed74) Signed-off-by: Wang Mingyu Signed-off-by: Richard Purdie
