Build 5.2.1 (Aug 2022)

Engine Updates:

Use of the Normal Flow Limited feature for dynamic wave flow
routing is now optional.
A refactoring bug causing excessive execution times for projects
with control rules has been fixed.
For kinematic wave storage routing, after convergence is obtained
the reported depth is based on the last volume value rather than
the next trial depth.
Corrections were made to the geometry tables for the Egg shaped
cross section at the two lowest relative depth levels.
The practice of setting a dry node's pollutant concentration to
0 even when it receives non-zero pollutant inflow (as introduced
in release 5.2.0) has been dropped.
When there is no inflow to a non-storage node its water quality
concentration now remains unchanged rather than being set to 0.
The definition of F_OFF in output.c was corrected for non-MS C/C++
compilers.
To eliminate having an excessive number of warning messages appear
in the Status Report:
- a message is no longer issued when a node's maximum depth is
  raised to match the crown of the highest connecting conduit.
- a message is no longer issued when a conduit's elevation drop
  or slope is adjusted to not fall below minimum allowed values.
