gh-120321: Make gi_frame_state transitions atomic in FT build (gh-142599)
...
This makes generator frame state transitions atomic in the free
threading build, which avoids segfaults when trying to execute
a generator from multiple threads concurrently.
There are still a few operations that aren't thread-safe and may crash
if performed concurrently on the same generator/coroutine:
* Accessing gi_yieldfrom/cr_await/ag_await
* Accessing gi_frame/cr_frame/ag_frame
* Async generator operations

gh-142527: Docs: Clarify that random.seed() discards the sign of an integer input ( #142483 )
...
If *a* is an integer, the sign of *a* is discarded in the C source code. Clarify this behavior to prevent foot guns, where a common use case might naively assume that flipping the sign will produce different sequences (e.g. for a train/test split of a synthetic data generator in machine learning).

Now that we specialize range iteration in the interpreter for the common

significant performance cost to making the iteration thread-safe.

The bytecode panel appears when a user generates a heatmap with
--opcodes and clicks the button to unfold a line and display the
bytecode instructions. Currently, an empty space appears on the
left where the line number, self, and total columns are displayed.
This area should instead extend those columns, rather than leaving
a gap.
