Documentation

The What’s new in Python 3.14 page currently states:

uuid4() and uuid8() are 30% and 40% faster respectively.

For uuid4, I’d interpret that as “faster than in Python 3.13”; but for uuid8, which is new in 3.14 as mentioned a few paragraphs earlier on the same page, the comparison is not clear.

Looking at GitHub, initial support for uuid8 was merged in November 2024 and the performance improvements were merged in January 2025; so this is effectively a performance comparison between 3.14a2 and 3.14a4. Perhaps that’s something that should not be included in user-facing documentation?
