brittonsmith/ytree: ytree 2.2 Release

Britton Smith; Meagan Lang

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 .
