+- Update to version 4.2
+  New feature:
+  * Threaded Motion Estimation (Experimental feature)-It uses a
+    dedicated threadpool to precompute Motion Estimation in
+    parallel.Improves encoding speed upto 1.5x for 1080p & lower
+    resolution on multi core machines with low frequency setting.
+    On high frequency systems or on machines with low number of
+    cores, the overhead of additional Motion estimation work may
+    outweigh parallelism
+  Enhancements to existing features:
+  * Add new Levels 6.3 to 7.2 specified in ITU-T H.265 (V9)
+    (09/2023) and above
+  * Improve Slices feature with check zeroMv
+  * Enable frame parallelism with MCSTF feature
+  * Updated support to signal AOM FGM params
+  * Improve quality with SBRC feature
+  * Updated DolbyVision P5 VUI defaults
+  API changes:
+  * API Support to enable Threaded Motion
+    Estimation(--threaded-me)
+  Optimizations:
+  * RISC V optimizations including SAD, SATD, DCT, IDCT, block
+    copy, pixel utilities, SAO, loopfilter, transpose kernels
+    resulting in 2x encoding speed.
+  * ARM SIMD optimizations including the use of NEON and SVE
+    instruction set extensions. The following algorithms now
+    have optimized SIMD implementations: DST, IDCT, SSE, SSD,
+    intra_pred_planar, pelFilterLumaStrong, interpolation,
+    planecopy, dequant_normal, blockcopy, pixel variance
+    resulting in 8% faster encoding speed compared to v4.1
+  Bug fixes:
+  * Fix memory leaks (no command line option, SEI buffer,
+    analysis save/load)
+  * Fix chroma qp offset for non yuv444 inputs
+  * Fix max supported input resolution
+  * Fix bugs with ARM SIMD optimizations
+  * Fix Alpha and Multiview feature flag support in x265_config
+  * Fix test harness issues, CMake errors
+  * Fix inconsistent output with aq-motion
+  * Fix crash with hist-scenecut on high bit-depth builds
+  * Fix lookahead concurrency bug
+  * Fix shared link issue (R_X86_64_PC32), yuv recon output
+     issue, rd-refine and dynamic-refine issue, inputs for
+     Windows named pipe,weighted prediction delta_chroma_offset,
+     crf and vbv issue in abr-ladder, psnr and ssim reported
+     with MCSTF feature, internally overflowed VBV variables
+  Known issues:
+  * Output mismatch between analysis save & load with cutree
+    with reuse level < 10
+  * Inconsistent hash mismatch with abr-ladder feature
+  * Performance regression observed with threaded-me feature on
+    high frequency systems and for higher resolutions (4k)
