Alexandria 3.1.0
This version introduces SEE pruning into search, netting a measurable gain in elo, most importantly it fixes a nasty (but thankfully rare) memory usage problem.
Every Alexandria user is highly advised to switch to this version, regardless of potential performance loss at untested TCs and of personal preferences.
This version also reverts the Time management changes made to the X moves in Y time format of TC because the new tm appears less effective.
