In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange. I set max_date_allowed = datetime.today().date(), but in the calendar, yesterday is the maximum date allowed. I see it in my apps, and it is also present in the first example on the DatePickerRange documentation page.

According to @rspadim, functions in entropy.py could use numpy array instead of strings, as it's better to numba.

Guide on how to implement this is available in the comments in PR #311 .

Heston model has accurate density approximations for European option prices, which are of interest.

The module implementing this method should live under tf_quant_finance/volatility/heston_approximation.py. It should support both European option puts and calls approximations. Tests should be in heston_approximation_test.py in the same folder.

At MacOS version of 1.3.4 -stable-, when adding a new Transaction, the amount field gets a pair of 00's each time you move to another text field or combobox option.

At 1.3.3 there is similar behaviour, however it adds ",00"... that means a comma, for decimals, so it's gets added just one time and the next time you move arround, it keep as is.

Looks like that because at 1.3.4 add just 0's wit
