In a major milestone for the automated taxobox system, more taxa articles now use automatic taxoboxes than manual ones. Particularly robust groups for automatic taxoboxes are turtles, primates, birds, rodents, amphibians and reptiles, sharks, and bivalves, with each project adopting automatic taxoboxes at rates greater than 95%. Only the fungi, arthropods, and microbiology projects had automatic taxobox adoption rates less than 25%. Read more in the 1 January update.
Thanks to user Trappist the monk, all citations to the IUCN using Template:Cite web or Template:Cite journal have now been swapped to Template:Cite iucn. This will prevent a recurrence of massive link failure should the IUCN change its URL format again. That does not address the 14.5k articles that cite the IUCN without the use of templates. For more background discussion, see here and here.
Vital Articles
The vital articles project on English Wikipedia began in 2004 when an editor transferred a list from Meta-Wiki: List of articles every Wikipedia should have. The first incarnation of the list became what is now level 3. As of 2019, there are 5 levels of vital articles:
Level 1: the 10 most vital articles (2009)
Level 2: the 100 most vital articles (2009)
Level 3: the 1,000 most vital articles (2004)
Level 4: the 10,000 most vital articles (2006)
Level 5: the 50,000 most vital articles (2017)
Each level is inclusive of all previous levels, meaning that the 1,000 Level 3 articles include those listed on Levels 2 and 1. Below is an overview of the distribution of vital articles, and the quality of the articles. While the ultimate goal of the vital articles project is to have Featured-class articles, I also considered Good Articles to be "complete" for the purposes of this list.
Animals (1,148 designated out of projected 2,400)
Cnidarians (5/8): 62.5% complete

Other arthropods (3/10): 30% complete
Reptiles (25/85): 29.4% complete
Amphibians (6/22): 27.3% complete

Other organisms—Archaea, Bacteria, Eukarya (5/62): 8.1% complete
Vegetables (6/96): 6.7% complete

Edible fruits (5/95): 5.3% complete
Non-flowering plants (1/30): 3.3% complete
Edible seeds, grains, nuts (1/69): 1.4% complete
Non-monocots (1/88): 1.1% complete
Carnivorous plants (0/2): 0% complete
Many articles have yet to be designated for Tree of Life taxonomic groups, with 1,942 outstanding articles to be added. Anyone can add vital articles to the list! Restructuring may be necessary, as the only viruses included as of yet are under the category "Health". The majority of vital articles needing improvement are level 5, but here are some outstanding articles from the other levels:
