can you add release notes for all issues fixed (or if 2 apply to the same one, pls list them there)
|
@shoyer looks good, some minor doc-like fixes. FYI, you need to list each issue sepately with (closes/fixes) in order to have it close them when merged. pls squash and ping when ready |

#5963 was actually already fixed prior to this PR, but I'll note it anyways :). |
Fixes GH8813 Fixes GH5963 Fixes GH5436 If the other argument has a dtype attribute, I assume that it is ndarray-like and convert the `Timedelta` into a `np.timedelta64` object. Alternatively, we could just return `NotImplemented` and let the other type handle it, but this has the bonus of making `Timedelta` compatible with ndarrays. I also added a `Timedelta.to_timedelta64()` method to the public API. I couldn't find a listing for `Timedelta` in the API docs -- we should probably add that, right? Next up would be a similar treatment for `Timestamp`.

two spaces in the beginning of the line are missing (to align it with ```Time..`). But can be fixed later when doing a clean-up of the whatsnew file
Fixes #8813
Fixes #5963
Fixes #5436
