JCVI Metagenomics Reports - Version 1.4.0

New Feature:
METAREP-461 Import dataset option for Admin via project page

METAREP-206 New Blast Page to find homologous sequences in selected datasets, display
and export results

METAREP-460 New Search Page option to search datasets using user defined sequences at
three homology cut-off levels (1E-5, 1E-20 and 1E-50)

METAREP-461 Deprecate common name field in Compare Page (will be replaced with a
high level summary, similar to the View Page Summary tab in the next release)

METAREP-462 Adjust Compare Page Layout for new versions of Chrome/Firefox

METAREP-435 New project link shortcut from user dashboard page project listings

METAREP-434 Select datasets for population creation by filtering datasets based on descriptions

METAREP-437 Updated download file header

METAREP-421 Fisher's Exact Test to compare two datasets (exact test)

METAREP-422 Equality of Proportions Test to compare two datasets (large sample approximation)

METAREP-432 False Discovery Rate calculation and filtering for multiple testing correction

METAREP-424 Compare two pathway maps with log odds ratio and significance color coding (available
for 'Statistical tests (2 datasets)' option on the KEGG pathway level; click on image in the last column)

JCVI Metagenomics Reports - Version 1.3.2 (bug fix release)

Bug Fixes:

METAREP-477 Mosaic Plot option was missing in scripts/r/plots.r 
METAREP-478 Population creation process expected core organization by project ID;
the process was fixed to work with a root level core organization as 
generated by the script. 

JCVI Metagenomics Reports - Version 1.3.1

New Feature:
METAREP-391 update viral evidence summary for view page

NCBI taxonomy version 09/30/2011: 280,602 new taxa KEGG version 09/01/2011: 21 new KEGG KO pathways; 1 new KEGG EC pathway Gene Ontology version 09/05/2011

METAREP-407 implement GO slim support for compare page
METAREP-406 implement mosaic plot option for compare page
METAREP-205 sequence export option for search page

Bug Fixes:
METAREP-408 fix compare panel misalignment
