IQ-TREE version 1.3.7

Aug 23, 2015

Version 1.3.7 is released with following changes:

Fix a bug introduced in 1.3.6 for new model selection procedure (-m TESTNEW).
Include L-BFGS-B algorithm (code taken from HAL_HAS package (Jayaswal et al., 2014) as the default to estimate model parameters. L-BFGS-B performs better than the previous BFGS implementation, for example, when optimizing LG4X and FreeRate models.
New option -suptag (used with -sup) when assigning support values from a set of input trees into a given tree, each tagged branch in the given tree will be assigned values of form support@tree1@tree2@...@treeK, corresponding to the IDs of the input tree where this branch occurs (requested by Max Maronna).
New option -t RANDOM to start tree search from a random starting tree (requested by Karen Meusemann).
