-Addition of over 100 families across the different available groups -Updated the topology of several sections of the tree, most notably Cyanobacteria (after Strunecký et al. 2023), Microsporidia (after Bojko et al. 2022 and Park & Poulin 2021) and Placozoa (Tessler et al. 2022) -Fixed the URLs for Wikipedia, the tutorial video in Youtube and the paper in BioRxiv

What´s new: -Fixed the Back button so you can get back to the main tree after visualizing subtrees -Text labels at nodes were made smaller so they do not overlap each other -Addition of Branchiopoda, a previosuly unavailable group -Updated the topology of several sections of the tree, including some orders of angiosperms (after Baker et al. 2021), extinct agnathans at the base of vertebrates (after Miyashita et al. 2021) and some extinct neornithine families, among others.

Whole source code modification and migration from Objective-C to Dart (Flutter), which includes the following new features: • Taxon metadata windows including an improved citation and reference formats as well as taxon synonyms • An “open all” button for unfolding every pre-collapsed branch at one • Addition of Hexapoda and Apicomplexa, as well as several newly described families since 2017, for a total of over 2000 added taxa • Improved layout for subtrees • A FAQ section

This app has been updated by Apple to display the Apple Watch app icon. -New topology of higher level relationships of dinosaurs (Ornithoscelida), after the results of Baron et al. (2017). -New topology of stem tetrapods and lissamphibians from the studies of Pardo. et al. (2017). -New topology of extant frogs (Lissamphibia: Anura) based on the phylogenomic analysis by Feng et al. 2017. -Several topological modifications to some clades of angiosperms based on studies implementing nuclear (rather than plastid) loci. -Updated higher level phylogeny of Bacteria based on phylogenomic analysis by Waite et al. (2017). -Several minor topological updates throughout the tree. -Addition of over 30 new families of extant and fossil taxa.

-Over 150 new families throughout different clades of the Tree of Life -Updated phylogenies of Monilophyta (ferns) and Excavata -Small topological modifications at the base of Unikonta

-Plants (Viridiplantae), Fungi (Fungi), and Opisthosporidians (Opisthosporidia) are now available in the PRO-version, leading to a >5000 total families to the current tree. -Several topological details regarding some basal extinct taxa of vertebrate groups were updated. -Addition of fossil families of Onychophorans. -Several minor topological updates in the different groups of the Tree of Life, as well addition of newly recognized families and removal of invalid ones.

-Haptophyta is now available in the PRO-version. -Updated higher level phylogeny of syndermatans (rotifers and acanthocephalans) based on a recent multi-locus study. -Correction of some misassigned pictures to taxonomic families at the tips of the tree. -Several minor topological updates in the different groups of the Tree of Life.

-Updated phylogeny of basal Neoaves based on phylogenomic analysis of Jarvis et al (2014). -Updated phylogeny of stem Gnathostomata to represent current consensus of cladistics analysis of fossil taxa: “placoderm” groups form a paraphyletic grade and “acanthodians” groups are within the gnathostome crown group. -Hemichordata and Tunicata are now available in the PRO-version. -Addition of over 50 extant and fossil families across the different groups of the Tree of Life. -Several minor topological updates in the different groups of the Tree of Life.

Bug fix.

-New vertebrate and bacterial families added -Slight topological modifications at the base of unikonts based upon recent phylogenomic studies

** Bug fix ** More images added

-A bug that erased most of the common names of the families was fixed -Ten families of extinct vertebrates, a new family of catfish, and a new family of bacteria were added to the tree

-CTENOPHORA (Comb jellies) is now available and may be opened. -Several small topological changes from recent studies, as well as the addition of some new families of vertebrates and bacteria.
