        sequentially, even when `parallel_iterations>1`, has now been fixed.
        However, the increased parallelism may result in increased memory use.
        Users who experience unwanted regressions should reset their
        `while_loop`'s `parallel_iterations` value to 1, which is consistent
        with prior behavior.

## Major Features and Improvements

*   `tf.keras`:

This means that now, if you set a value in a context variable before `yield`, the value would still be available after `yield` (as you would intuitively expect). And it also means that you can reset the context variable with a token afterwards.

For example, this works correctly now:

```Python
from contextvars import ContextVar
from typing import Any, Dict, Optional

pkg go/doc, type Package struct, Examples []*Example
pkg go/doc, type Type struct, Examples []*Example
pkg hash/maphash, func MakeSeed() Seed
pkg hash/maphash, method (*Hash) BlockSize() int
pkg hash/maphash, method (*Hash) Reset()
pkg hash/maphash, method (*Hash) Seed() Seed
pkg hash/maphash, method (*Hash) SetSeed(Seed)
pkg hash/maphash, method (*Hash) Size() int
pkg hash/maphash, method (*Hash) Sum([]uint8) []uint8
