[0.2.0] - 2020-09-03¶
[ADDED] added the pipeflow option “reuse_internal_data” which allows to reuse the system matrix from one pipeflow to the next in combination with “only_update_hydraulic_matrix” - useful for timeseries calculations

[CHANGED] names of parameters for regression function in pump
[CHANGED] pressure lift for pumps is now always >= 0
[CHANGED] on reverse flow, the pressure lift for pumps is 0
