DIAMOND v2.2.1

• Improved the performance of the search and clustering workflows.
• Fixed an issue of increased memory use in greedy vertex cover computation.
• Fixed a potential Record count not set error message during clustering output.
• Removed the --linclust-chunk-size and --connected-component-depth options.
• Fixed an issue of increased memory use in the clustering workflows.
• Fixed an issue that could cause incorrect parsing of taxonomic nodes and names data when using a custom-made nodes.dmp or names.dmp file with non-monotonic taxonomic ids.
• Missing taxonomy node information for a taxid will no longer cause an error but be accordingly indicated in the output file.
• Added compatibility support of taxonomic rank information for databases built with v2.1.11 or earlier.
• Added support for clustering by traceback sequence identity (--id) instead of approximate sequence identity (--approx-id).
• Fixed an issue (present since v2.1.25) that could cause clustering workflows not to correctly apply the --comp-based-stats command line option.
• Added support for clustering with the first clustering round being all-vs-all alignment.
• Temporarily removed the reassign workflow.
• Fixed an issue of missing sequence identifiers in the output for BLAST databases built without using -parse_seqids.
• Fixed a bug (present since v2.1.17) that caused BLAST alias databases filtered by sequence id not to function correctly.
