This release fixes a bug with classification when k-mer length is equal to minimizer length, and provides new retry behavior for the
--use-ftp flag to make downloading more robust.
This is the first non-beta release of Kraken 2. This version includes bug fixes and revisions to the build process to aid in making Kraken 2 databases more easily reproducible. Version 2.1.0 also introduces a new experimental feature to report the number of distinct minimizers associated with a taxon in the sequencing data, similar to the functionality found in the KrakenUniq program. Please see
CHANGELOG.md for more details on version-specific changes and the operating manual section on "Distinct minimizer count information" to learn how to use the new feature.
This version includes various fixes, including adaptation to NCBI file structure changes. Default parameters for the k-mer length, minimizer length, and number of minimizer spaces have also changed in this version. Please see
CHANGELOG.md for more details.
Version 2.0.7 includes the option to set a limit to database size while building, along with many other fixes and updates. Please see the
CHANGELOG.md file for more details.
