TF-2.21.0-CC (2026-07-06)
This release provides the pre-built TensorFlow 2.21.0 C/C++ and TensorFlow-Lite 2.21.0 C shared libraries (with Flex delegate) for WasmEdge TensorFlow plugins on manylinux_2_28_x86_64, manylinux_2_28_aarch64, darwin_x86_64, darwin_arm64, and android_aarch64 (TensorFlow-Lite only).
- All libraries are built from the pristine
v2.21.0tag — no source patch, no./configure. - The TensorFlow asset ships the two-library pywrap pair (
libtensorflow_cc+libtensorflow_framework, SONAME-form filenames such aslibtensorflow_cc.so.2) — the same libraries the official TensorFlow pip wheels contain, built by the same pipeline. Consumers link both,libtensorflow_ccfirst. - Linux libraries are built with TensorFlow's hermetic clang toolchain (GLIBC ≤ 2.27 / GLIBCXX ≤ 3.4.22 / CXXABI ≤ 1.3.11 requirements; AVX baseline on x86_64, armv8-a on aarch64). Linux platform names move from
manylinux2014tomanylinux_2_28. - macOS libraries target macOS 12.0+ (arm64) / 10.15+ (x86_64).
- The
android_aarch64asset containslibtensorflowlite_c.soonly (arm64-v8a, minSdkVersion 23, static libc++), built with Android NDK r25c. - Vendored headers refreshed to the TensorFlow v2.21.0 include closure (
tensorflow/,tsl/,xla/trees).
