Updates & announcements
Prokaryote phylum names
As previously announced, NCBI Taxonomy began updating phylum names for prokaryotes in January 2023. Informal phylum names in long use (e.g., Firmicutes, Proteobacteria) were changed to newly formalized names (e.g. Bacillota, Pseudomonadota, respectively). This update affected over 40 NCBI TaxIDs at phylum rank. The rollout of new phylum names is now complete! The flatfiles in this release contain the new phylum names.
New eukaryotic genome annotations
This release includes new annotations generated by NCBI’s eukaryotic genome annotation pipeline for 33 species, including:

The total volume of ASN.1 files in the ‘Complete’ node grew by 24%. This size increase is an artifact of a change in the ordering of records that affects gzip efficiency.
