Template.`var_scope` property renamed to `.variable_scope` *
SyncReplicasOptimizer is removed and SyncReplicasOptimizerV2 renamed to
SyncReplicasOptimizer. * `tf.zeros_initializer()` and `tf.ones_initializer()`
now return a callable that must be called with initializer arguments, in your
code replace `tf.zeros_initializer` with `tf.zeros_initializer()`. *
`SparseTensor.shape` has been renamed to `SparseTensor.dense_shape`. Same for

### Refactors

* ♻️ Refactor internal `check_file_field()`, rename to `ensure_multipart_is_installed()` to clarify its purpose. PR [#12106](https://github.com/fastapi/fastapi/pull/12106) by [@tiangolo](https://github.com/tiangolo).

[u] and [v] // are odd) so coefficients stay in bounds. // 4. Replace the [u >= v] check with [u > v]. This changes the end // condition to [v = 0] rather than [u = 0]. This saves an extra // subtraction due to which coefficients were negated. // 5. Rename x and y to a and n, to capture that one is a modulus. // 6. Rearrange steps 4 through 6 slightly. Merge the loops in steps 4 and // 5 into the main loop (step 7's goto), and move step 6 to the start of // the loop iteration, ensuring each loop iteration...
