Greetings! yt_astro_analysis version 1.1 is released! yt_astro_analysis is an extension of yt for astrophysical analysis. This is the first stable release of yt_astro_analysis to be compatible with yt version 4.0 and later. New Features - The HaloCatalog has been significantly refactored (#58 <https://github.com/yt-project/yt_astro_analysis/pull/58>, #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 #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 #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 #84 <https://github.com/yt-project/yt_astro_analysis/pull/84> - Add restart option for rockstar #82 <https://github.com/yt-project/yt_astro_analysis/pull/82> - Adding an outer_radius parameter to the iterative COM callback #34 <https://github.com/yt-project/yt_astro_analysis/pull/34> - Remove the sunyaev_zeldovich analysis module.
