Go 1.22 added contention on runtime-internal locks to the [`mutex`
profile](/pkg/runtime/pprof#Profile). Contention on these locks is always
reported at `runtime._LostContendedRuntimeLock`. Complete stack traces of
runtime locks can be enabled with the [`runtimecontentionstacks`

    the graphical user interface (GUI) of TensorFlow Debugger (tfdbg), is now in
    alpha.
*   Experimental support for reading a sqlite database as a `Dataset` with new
    `tf.contrib.data.SqlDataset`.
*   Distributed Mutex / CriticalSection added to
    `tf.contrib.framework.CriticalSection`.
*   Better text processing with `tf.regex_replace`.
*   Easy, efficient sequence input with
    `tf.contrib.data.bucket_by_sequence_length`
