This puzzle may be considered as a little more challenging sequel to my puzzle The one and only sum, which introduced the "same sum constraint". Feedback is always greatly appreciated! The rules are as follows:

Normal Sudoku rules apply. Box borders divide the blue line into segments with the same sum. Cells that are equidistant from the central cell of a purple Zipper line (marked by the circle) must sum to the digit in the circle. A pink Renban line contains a set of non-repeating consecutive digits in any order. Adjacent cells along a green German whisper line contain digits that differ by at least 5. The sum of all digits that belong to one constraint type (e.g. all digits on Renban lines) is the same for each constraint types and must be deduced by the solver.
