IQ-TREE version 1.4.3

Jul 15, 2016

This version fixes various problems improving software stability.

New features:

Better parameter estimates for I+G model.
More flexible mixture models for model testing with -madd option (requested by David Kerk).
The protein mixture model CF4 of Wang et al. (2008) now includes Gamma rate heterogeneity by default.
Support invariable sites plus FreeRate [+I+R] model (requested by Lars Jermiin).
New option --sequential to read sequential phylip alignment file format.

Bug fixes:

Failture too estimate too extreme GTR rate parameters (reported by Stephen Crotty).
Bug with likelihood scaling for constant sites under invariable site [+I] model (reported Remi Denise).
Crash with optimizing codon model parameters (reported by Xiaofan Zhou).
Redundant codon models for model selection (reported by Xiaofan Zhou).
Segfault caused by unaligned memory for partition model with binary data (reported by Marek L. Borowiec).
Crash with -wbtl option (reported by Teo).
Crash with -mtree for partition finding (reported by a web user).
A rare bug in NNI hill-climbing search.
A bug in printing .rate file via -wsr option (reported by Tim McInerney).
Several other minor issues.
