============= RapidWright 2020.1.4-beta released on 2020-11-02 ================
Notes:
 * Adds 2020.1 update 1 Vivado devices (XCVU19P, XCZU46DR, XCZU47DR,
   XCZU48DR, XCZU49DR; Alveo devices: U55N, U55C)
 * Adds a netlist flattening helper method ()
 * Adds preliminary support for reproducing intermediate clock routing
   state through the use of partial PIPs - not necessarily modifiable
   though.  This is intermediate routing information added to clock nets
   after during place_design that informs clock routing during
   route_design.  Previously this was causing some ERRORs when writing
   out placed DCPs.
   * Some PIPs in these intermediate clock nets can have PIPs with no
     end wire.  This can be checked with PIP.isEndWireNull().  Or
     compare the end wire index with PIP.NULL_END_WIRE_IDX (0x0000FFFF).
