Recommend adding to what's new 3.14.rst

[Eclips4]

Could you please add a note about these additions to the Doc/whatsnew/3.14.rst?

[hugovk]

We don't usually include things like "If you have Python 3.14 or later" because each set of docs relates to one specific Python version.

But perhaps it's okay here because turtle is often used by beginners who might read these docs but have 3.12 or 3.13 installed?

That makes a lot of sense, but in this specific case I think it's useful. Many learners are at universities or schools with old versions of Python, and they might not be aware that there are several versions of Python. So I think it's useful to make it very clear that this is a new feature.

Sorry to reopen, but IMO this reads a little bit unexpected. How about something in the lines of:

Starting with Python 3.14, you can use [...] instead of [...].

What do you think?

[danielhollas]

Why the extra newline between this and the previous import statement?

[yngvem]

We have tried to address the review comments now 🙂

Some final minor nitpicks. Otherwise looks great!

[picnixz]

Last one and I am good! (modulo Hugo's comment)

I promise there really shouldn't have anything left for me. Thank you for your patience! (my reviews tend to have multiple parts depending on the hour when I do the review).

No worries, thanks a lot for the thorough review!

[erlend-aasland]

This looks good, but I have some remarks and nits. PTAL.

This can also be written more compact. Though, I'm not sure it is more readable, so feel free to ignore this :)

Suggested change

	... dist = 2
	... for i in range(200):
	... fd(dist)
	... rt(90)
	... dist += 2
	... for dist in range(0, 400, 2):
	... fd(dist+2)
	... rt(90)

[erlend-aasland]

Ditto.
