     Type:  enhancement     |      Status:  new

----------------------------+-----------------------------------------------
 The authors of the L-BFGS-B algorithm have released a new version this
 year, v.3.0. Compared to the existing v.2.1 code, the authors have fixed
 some bugs and introduced an enhancement to the optimization process that
 could reduce the CPU time by up to 8 times. The new version also uses
 slightly less memory.
