- Newly written should be using `signal.frames` to determine the owners of a signal, for
compatibility reasons `signal.frame` is still set, but only when a signal is associated with one
frame
- Physical values might be rounded the wrong way depending on the user's intention. This type of
rounding should generally work better in values ranging from `0-X`, for example `49.9` is no longer
rounded down to `49`. If this is undesired the user can in most cases offset the input by `0.5` and
it should work as previously as `-0.5` rounds to `0`, check
[Python's round function](https://docs.python.org/3/library/functions.html#round) for more.
