MATLAB: Result of asind changed between R2016b and R2019b

asindMATLAB

I noticed that the result of the 'asind' function changed slightly for some input values when I upgraded from R2016b to R2019b.
For example, in R2016b:
>> format long
>> asind(0.7)
ans =
  44.427004000805702
In R2019b:
>> format long
>> asind(0.7)
ans =
  44.427004000805695
I realize this is a tiny difference, but I didn't expect it. I searched the release notes for everything between these versions and didn't find anything relevant. Did I overlook something, or does behavior like this change from version to version without mention?

I'm not 100% certain offhand but I suspect this is related to the change in sind and cosd in release R2019a described in bug report 1839169.
