The BLAST+ 2.10.0 release is now available from at FTP site. The new version offers the following improvements:

NCBI BLAST have added new columns to the Descriptions Table for web BLAST output.

BLAST+ stand-alone updated to version 2.2.31

ncbi.github.io - Magic-BLAST is a tool for mapping large next-generation RNA or DNA sequencing runs against a whole genome or transcriptome. Each alignment optimizes a composite score, taking into account simultaneously the two reads of a pair, and in case of...

The Basic Local Alignment Search Tool (BLAST) is a powerful bioinformatics program used to compare an input sequence (such as DNA, RNA, or protein sequences) against a database of sequences to find regions of similarity.

github.com - MMseqs2 (Many-against-Many sequence searching) is a software suite to search and cluster huge protein and nucleotide sequence sets. MMseqs2 is open source GPL-licensed software implemented in C++ for Linux, MacOS, and (as beta version, via cygwin)...

Ancestral sequence reconstruction (ASR) – also known as ancestral gene/sequence reconstruction/resurrection – is a technique used in the study of molecular evolution

The main advance is the ability to provide usage reports to NCBI to help us improve BLAST.

We have made changes the nr version 5 database, (nr_v5), to facilitate better search results and improved performance by reducing the number of redundant titles in the nr_v5 database used by webBLAST, which is also available for BLAST+ users.
