New Features
^^^^^^^^^^^^

 * The HaloCatalog has been significantly refactored
   `PR #58 <https://github.com/yt-project/yt_astro_analysis/pull/58>`__, `PR #62 <https://github.com/yt-project/yt_astro_analysis/pull/62>`__ with
   the following additional improvements:

     * the interface to the Rockstar halo finder is now compatible with the latest version of Rockstar Galaxies `PR #55 <https://github.com/yt-project/yt_astro_analysis/pull/55>`__
     * all halo finders now support being run with time-series of datasets
     * halo particle ids now savable with FoF and HOP halo finders `PR #52 <https://github.com/yt-project/yt_astro_analysis/pull/52>`__
     * looping over halos is done with io chunks instead of ds.all_data for a significant speedup and reduction in memory
     * Allow more flexibility for specifying rockstar particle mass `PR #84 <https://github.com/yt-project/yt_astro_analysis/pull/84>`__
     * Add restart option for rockstar `PR #82 <https://github.com/yt-project/yt_astro_analysis/pull/82>`__
     * Adding an outer_radius parameter to the iterative COM callback `PR #34 <https://github.com/yt-project/yt_astro_analysis/pull/34>`__

 * Remove the sunyaev_zeldovich analysis module. This is now `ytsz <https://github.com/jzuhone/ytsz>`__. `PR #79 <https://github.com/yt-project/yt_astro_analysis/pull/79>`__
 * Drop support for python 3.6 `PR #100 <https://github.com/yt-project/yt_astro_analysis/pull/100>`__, `PR #101 <https://github.com/yt-project/yt_astro_analysis/pull/101>`__

Version 1.0
-----------

Release date: *October 11, 2018*

This is initial stable release of yt_astro_analysis. Before this, all
code in here was contained in the `yt package's

submodule. Version 1.0 of yt_astro_analysis is functionally identical
to the ``analysis_modules`` from yt version 3.5.0.
