ytree version 2.2 is released!
ytree is an extension of yt for working with merger-tree data from multiple sources.
This release adds a couple new features as well as improvements for i/o and memory usage.
New feature: vector fields return x/y/z components of a vector as a single array with automatically created magnitude fields.
New feature: a select_halos function to search all trees for halos matching specified criteria.
Enhancement: significant refactors of the field and i/o systems to reduce memory, speed up field access, and simplify implementing new frontends.
Enhancement: upgrades to the testing infrastructure.
ytree can be installed with pip:
pip install ytree
or from source, by going to https://github.com/brittonsmith/ytree
git clone https://github.com/brittonsmith/ytree cd ytree pip install -e .
