Version 4.3.19 is released and it it fixes a few minor bugs plus a couple of more serious ones to do with the geometry processing engine.
In particular the connectivity extraction algorithm has had improvements made that eliminate a few corner case bugs that could cause incorrect connectivity.
LVS with a hierarchical netlist still needs more testing as I just have 2 testcases currently.
Lastly more regression tests are being added to ensure bugs don't reappear!
