+~~~~exercism/note
+ From 2002 to 2022, Python used an algorithm called [`Timsort`][timsort] internally to arrange lists, but switched to [`Powersort`][powersort] from `Python 3.11` onward.
+You can read more details and discussion on the change from the core Python team in the GitHub [issue 78742][78742].

+For technical details on the algorithm, see the J. Ian Munro and Sebastian Wild paper [Nearly-Optimal Mergesorts: Fast, Practical Sorting Methods That Optimally Adapt to Existing Runs][nearly-optimal-mergesorts]
