Hello everyone,

libvpx v1.16.0 Xenonetta Duck is finalized.
Here's the release note.

Thanks.

Release Note

This release includes Arm SVE2 and Neon optimizations for 12-tap filters,

AVX512 implementations for SAD, support for per-frame and per-spatial-layer
PSNR calculation, and numerous bug fixes.

This release is available from the git repository and the v1.16.0 tarball, along

with the asc file.

• Upgrading:
• This release is ABI incompatible with the previous release.
• Unit tests require C++17 to build.
• Support for 32-bit iOS targets (armv7, armv7s, and i386) has been removed.

• Enhancement:
• Optimized Arm SVE2 and Neon implementations for 12-tap convolution filters.
• Optimized Neon High Bitdepth (HBD) SAD and sad_avg functions.
• Added Arm Neon DotProd and I8MM implementations for vpx_convolve12.
• Added AVX512 implementations for SAD64 and sad_skip functions.
• Added SSSE3 and AVX2 implementations for 12-tap temporal filter prediction.
• Added support for per-frame and per-spatial-layer PSNR calculation.
• Adjusted temporal filter strength to improve visual quality and reduce block
  artifacts.
• Added support for darwin24 (macOS 15) and darwin25 (macOS 26).
• libwebm is upgraded to commit b4f01ea.

• Bug fixes:
• Fix to heap buffer overflow in vp9_deblock, vp9_post_proc_frame, and
  vp9_pack_bitstream.
• Fix to integer overflow in vp9_highbd_post_proc, vp9_rc_regulate_q,
  tiny_ssim, and vp9_calc_pframe_target_size_one_pass_cbr.
• Fix to use-of-uninitialized-value in vp9_highbd_post_proc, mfqe, and
  vp8_datarate_test.
• Fix to out-of-bounds in log_tile_cols_from_picsize_level.
• Fix to double free on initialization failure in vpx_codec_enc_init_multi.
• Fix to division-by-zero crash in vpxenc with 0 FPS numerator input.
• Fix to various build failures for Arm/SVE2, macOS cross-compilation, and
  Xcode 16.
