What did the 'new' parameter in numpy's histogram() function do?
I stumbled across some old code (>10 years) and one of the lines reads:
c, be = np.histogram(s, bins=values, new=True)
This new
parameter is no longer there. I'm trying to make this code work, but I've no idea what that new
parameter did. I haven't found anything about it online. I could just remove it, but then I wouldn't know what it was used for and if it was perhaps something important.
Can anybody tell me what this parameter did and how can it be reproduced now?

That argument allowed the older version to provide bin creation functionality equal to that of newer versions (>= 1.3). I found the following note in code at this link
Either an integer number of bins or a sequence giving the
bins. If bins is an integer, bins + 1 bin edges
will be returned, consistent with :func:numpy.histogram
for numpy version >= 1.3, and with the new = True argument
in earlier versions.
And this from the docs linked in the comment:
new : {None, True, False}, optional
Whether to use the new semantics for histogram:
- None : the new behaviour is used, no warning is printed.
- True : the new behaviour is used and a warning is raised about the future removal of the new keyword.
- False : the old behaviour is used and a DeprecationWarning is raised.
As of NumPy 1.3, this keyword should not be used explicitly since it will disappear in NumPy 1.4.

So it appears that it can indeed be removed with no unexpected consequences. Thank you!
