document the change to .base semantics introduced by Add maskna= and ownmaskna= parameters to np.asarray and friends (6c0ad59)

Per comment:

6c0ad59#commitcomment-1819948

this change should be documented and added into the release notes.

Those parameters were removed again in #297, so there's nothing to document...

[njsmith]

Oh, you mean, document the change in the .base parameter that was also included in that commit... sorry.

[embray]

Right...I don't fully understand what the maskna and ownmaskna parameters are, or how they were meant to be used. But their implementation also included changes to .base, which I'm guessing were necessary anyways. And I remember seeing some mailing list discussions about changing .base to only include arrays that own their data (a change a welcome, which makes walking .base a lot easier and closes some reference cycles that I've had to fight with in my own code).

But it's sort of unrelated to the original change that it rode in on.

[teoliphant]

This is related to issue #470 so I'm closing this one.

[certik]

I've added a note about .base into the release notes in PR #2737. Let me know if you think it is sufficient.

[embray]

Works for me.

[certik]

This is now fixed by #2737.
