Release 2.22.0

TensorFlow

Breaking Changes

The TensorBoard dependency is no longer included by default. If you use tf.summary.* APIs or tf.keras.callbacks.TensorBoard, please install the tensorboard package separately (pip install tensorboard). Otherwise, TensorFlow will raise an ImportError.

In tensorflow/c/experimental/filesystem/filesystem_interface.h, removed TF_TransactionToken and associated APIs.

Major Features and Improvements

• Support for Python 3.14 has been added.
• Initial support for NVIDIA CUDA 13 has been added. Users on CUDA 13 can install via pip install tensorflow-cuda13 (or pip install tensorflow[cuda13]).
• tf.lite
  • Adds support for QUI4 (Quantized Unsigned 4-bit) in Dequantize operator.
  • Adds support for FP16 and BF16 in Unpack operator.
  • Adds support for FP16 in Transpose and DynamicUpdateSlice operator.
  • Transpose now supports up to 8D tensors.
  • Adds support for FLOAT8_E4M3FN and FLOAT8_E5M2 data types.

Bug Fixes and Other Changes

• BatchFunction Operator

  • Adds the num_warmup_batch_threads op attribute to support a separate thread pool for processing warmup requests.
  • Adds the per_criticality_batch_timeout_micros op attribute to support different batch timeouts for different criticality levels.

• TensorFlow API

  • Exports __new__ in public API golden files for subclasses of tuple (like tf.io.FixedLenFeature) to fix false positives during static type checking.

• tf.data

  • Fixes a bug in tf.data.Dataset.scan where the shape of the state returned by scan_func was not strictly validated against the initial state.

• tf.image.adjust_contrast

  • Registers the missing Python gradient for the AdjustContrastv2 op, so tf.image.adjust_contrast can now be differentiated with GradientTape. Fixes #126083.

• tf.nn.softsign

  • Fixes second-order gradients of tf.nn.softsign. Differentiating twice previously failed with a lookup error because the SoftsignGrad backward op had no registered Python gradient.

• tf.math.reciprocal

  • Constrains the XLA registration of Reciprocal and Inv to the types that have a device kernel, so jit_compile=True no longer silently accepts the integer inputs that eager execution and autoclustering reject. Fixes #126414.

• tf.experimental.numpy

  • tf.experimental.numpy.isclose and tf.experimental.numpy.allclose now apply rtol and atol to integer inputs, matching NumPy, instead of comparing with pure equality. The comparison stays in integer arithmetic; combining integer inputs with floating-point tolerances (including the defaults) now raises an error unless automatic type promotion is enabled, which keeps the cost of promotion opt-in.

• oneDNN (MKL) convolution and transpose kernels

  • Raises InvalidArgumentError instead of aborting the process for a rank-mismatched Conv3DBackpropFilterV2 input and for ConjugateTranspose on a scalar. Fixes #118340 and #118345.

• tf.image.non_max_suppression

  • Fixes a segmentation fault under jit_compile=True when boxes and scores are empty. The XLA lowering now returns an empty selection, matching the non-XLA kernels. Fixes #117245.

Release 2.20.0

TensorFlow

Breaking Changes

• The tensorflow-io-gcs-filesystem package is now optional, due its uncertain, and limited support. To install it alongside tensorflow, run pip install "tensorflow[gcs-filesystem]".

Major Features and Improvements

• tf.data
  • Adds autotune.min_parallelism to tf.data.Options to enable faster input pipeline warm up.
• tf.lite
  • tf.lite will be deprecated, in favor of the new repo https://github.com/google-ai-edge/LiteRT.
  • The duplicated source will also be removed from the TF repo.

Release 2.18.1

Security

• Updates curl to 8.11.0 to handle CVE-2024-2004, CVE-2024-2379, CVE-2024-2398, CVE-2024-2466, CVE-2024-6197, CVE-2024-7264, CVE-2024-8096 and CVE-2024-9681.

Bug Fixes and Other Changes

• Loosen ml_dtypes upperbound to < 1.0.0 to reduce conflicts when installed with other ML ecosystem components.

Breaking Changes

• tf.lite
  • Interpreter:
    • tf.lite.Interpreter gives warning of future deletion and a redirection notice to its new location at ai_edge_litert.interpreter. See the migration guide for details.
• Tensorflow-tpu for this patch is skipped due to some sparsecore related bugs. We suggest to upgrade to 2.19.0 instead.

Release 2.19.0

TensorFlow

Breaking Changes

• LiteRT, a.k.a. tf.lite:
  • C++ API:
    • The public constants tflite::Interpreter:kTensorsReservedCapacity and tflite::Interpreter:kTensorsCapacityHeadroom are now const references, rather than constexpr compile-time constants. (This is to enable better API compatibility for TFLite in Play services while preserving the implementation flexibility to change the values of these constants in the future.)
  • Python API:
    • tf.lite.Interpreter gives deprecation warning redirecting to its new location at ai_edge_litert.interpreter, as the API tf.lite.Interpreter will be deleted in TF 2.20. See the migration guide for details.

Known Caveats

Major Features and Improvements

• tf.lite
  • tfl.Cast op is now supporting bfloat16 in runtime kernel.

Bug Fixes and Other Changes

• We have stopped publishing libtensorflow packages but it can still be unpacked from the PyPI package.
