A bunch of old obsolete solvers removed and are no longer supported.
@araujoms improved support for complex cones via sedumi in automatic dualization.
BMIBNB improvements both algoritmically and performance.
BNB cleaned up bug fixes (memory hogging) and improved performance for some models (more on that later in separate post).
GUROBI options structure now up to date.
DAQP added as supported solver.
yalmiptest cleaned up and improved.
Added some geometric operators such as vertex, isoutside, starpolygon.
Experimental (pre-alpha) support of nonlinear semidefinite programming (more on that later in separate post).
Option ‘usex0’ should be updated to ‘warmstart’ (both supported for now)
Code fixed to support Octave 8.
