  **Release 2.1.0** (2024-03-31) implemented the **maximal matched-pairs tests** to asses violations of the data to the Stationarity, Reversibility, and Homogeneity (SRH) assumptions made by maximum-likelihood phylogenetic models, as implemented in [IQ-TREE](http://www.iqtree.org/). In addition, [**ASTRAL-IV**](https://github.com/chaoszhang/ASTER/blob/master/tutorial/astral4.md) is used to estimate the species tree directly from the filtered ML source gene trees, which computes terminal and internal branch lengths in substitution-per-site units.
  
  [**Release 2.2.0** (v2.2.0, 2024-04-14)](https://github.com/vinuesa/get_phylomarkers/releases/tag/2.2.0) contains new features, significant code improvements, binary updates, and some bug fixes. Among the new features, we would like to highlight the following ones:
+ 
 -significant extension of run mode 2 (<code>run_get_phylomarkers_pipeline.sh -R 2</code>) for **population genetics** (multiple sequences from the same species):
-- <code>run_get_phylomarkers_pipeline.sh</code> now also calls the C binary [**WEIGHTED-ASTRAL**](https://github.com/chaoszhang/ASTER) to estimate a species tree using as input the filtered gene trees estimated by [iqtree2](http://www.iqtree.org/) or [FastTree](http://www.microbesonline.org/fasttree/) from the core-genome clusters computed by [get_homologues](https://github.com/eead-csic-compbio/get_homologues). 
-- The main script <code>run_get_phylomarkers_pipeline.sh</code> added complex protein mixture models for concatenated protein alignments, prints script invocation arguments to STDOU at the beginning of the run, and prints a summary results of the different filtering steps before exiting. Read the [**Release v2.2.0**)](https://github.com/vinuesa/get_phylomarkers/releases/tag/2.2.0) notes for further details. Note that users of this release interested in run mode 2 (-R 2) for to compute a population tree, will need to install [snp-sites](https://github.com/sanger-pathogens/snp-sites), as explained in the current [INSTALL.md notes](https://github.com/vinuesa/get_phylomarkers/blob/master/INSTALL.md).

Thanks to Alfredo Hernández @ccg_unam for compiling snp-sites-static.

  **GET_PHYLOMARKERS** can also estimate **ML and parsimony trees from the pan-genome matrix**, including unsupervised learning methods to determine the optimal number of clusters from the pan-genome and average genomic distance matrices.
