Aug 23, 2018 Release
Temporarily disable AU test due to unresolved numerical issue when bp-rell are all zeros.
Checkpointing issue in ModelFinder for mixture models causing incorrect likelihoods with e.g.
-madd C10 (reported by Juergen Strassert).
Checkpointing Lie Markov models. (v1.6.6) Incomplete parsing of site positions of partition file (reported by Alexey Kozlov). Parsing polymorphic states from NEXUS file (reported by Steven Heritage). Use of only 1 thread when #partitions < #cores (reported by Alexey Kozlov). Double RAM usage for
-bnni option (reported by Juergen Strassert).
Over-bound for optimizeTreeLengthScaling causing too long branch lengths in extreme cases (reported by vikaszsi77). Exclude ORDERED model by default for morphological data due to frequent numerical underflow. (v1.6)
-m ..MERGE.. wrong concatenateAlignments with missing data (reported by David Dunchene).
Error message instead of crash when using
-bsam with non-partition model (reported by Sarah Jensen).

Jul 1, 2018 Release
This version contains a number of bugfixes and is highly recommended for all users.
Issue with internal tree node names changed from slash to underscore (reported by JP Flandrois). Wrong FREQ_UNKNOWN assertion with protein mixture models, e.g. LG4X (reported by Giddy Landan). Disallow specifying both
-lmap option (reported by Giap Nguyen).
Reading nexus polymorphic characters for non-DNA data (reported by a web user). Amino-acid O (22nd amino-acid) is accepted as missing data (reported by Cuong Dang). Negative initial free-rates in rare cases (reported by Paul Frandsen). Memory leak in reading NEXUS alignment. Crash with resampling strategy (
-bsam) for standard bootstrap (
-b) and jackknife (
Crash with standard bootstrap and partition merging (
-m ...MERGE) (reported by Guoqing Li).
Wrong error with codon models and
-t RANDOM (reported by Karen Meusemann).
Parsing error with blank chars in partition file (reported by David Maddison). Freezing caused by old Intel OpenMP library (reported by David Maddison). Too strict assertion about one applied NNI (reported by Karen Meusemann). Error message when specifying mixture with GHOST model (reported by Anja Spang).

May 8, 2018 Release
GTR20 protein model does not optimise rate parameters. Replace odd characters in taxon names in tree file by underscore as done with alignment file (issue #31). Replace odd characters in taxon names in cluster file by underscore (issue #54). Crash with combination of bootstrap (-b option), partition model (-spp) and model testing (-m TEST) at the phase of analysing original alignment (reported by paul.madeira).

Apr 30, 2018 Release
--runs to perform multiple tree searches (issue #64 requested by David Maddison). This is motivated by a recent evaluation
(Zhou et al. 2018) showing that 10 independent runs outperformed single run in terms of likelihood maximisation. Print branch lengths scaled in number of substitutions for PoMo models. Support specifying 6 GTR rates and G-T rate to be zero from command line (requested by Ben Redelings). New option
--show-lh to compute tree log-likelihood without parameter optimisation (issue #67).
Fix compilation with gcc 4.8. Incorrect parsing
+P for PoMo model string (thanks Carolin Kosiol).
Issue #66: Incorrect frequency mixture model when coupled with
GTR20 (reported by Dominik Schrempf).
.ufboot trees file contains partial branch supports by combination of
-alrt (reported by Guifre Torruella Cortes).
Crash in likelihood computation for
+ASC model when some states are rare (reported by Paul Madeira).
Numerical instability for codon models by reducing upper bound of omega/kappa from 100 to 50 (reported by Aleksas Lab). Crash reading DNA model from file (reported by Benjamin Redelings). Crash with
