Breaking Changes

●Issue #1

`tf.lite.Interpreter` is deprecated and will be removed; it now redirects to `ai_edge_litert.interpreter`. Update imports to the new location.

●Issue #2

Tensorflow‑tpu support is omitted in this patch due to sparsecore bugs; upgrade to version 2.19.0 for TPU functionality.

Migration Steps

  1. 1
    Replace any usage of `tf.lite.Interpreter` with `ai_edge_litert.interpreter` as described in the migration guide https://ai.google.dev/edge/litert/migration.
  2. 2
    If you rely on Tensorflow‑tpu, skip this 2.18.1 patch and upgrade directly to 2.19.0.

Release Summary

This patch updates curl for security, loosens the ml_dtypes version bound, and deprecates tf.lite.Interpreter in favor of ai_edge_litert.interpreter, while dropping TPU support until 2.19.0.
