opencosmo 0.9.4 (2025-09-26) ============================ Bugfixes -------- - Fix a bug that could cause opening halos and galaxies only to fail opencosmo 0.9.3 (2025-09-25) ============================ Bugfixes -------- - Fix an issue that could cause opens with multiple files to fail in MPI contexts opencosmo 0.9.2 (2025-09-25) ============================ Bugfixes -------- - Fix a but that could cause opening properties and profiles without particles to fail. opencosmo 0.9.1 (2025-09-16) ============================ Bugfixes -------- - Re-add license file to package for conda-forge compatability opencosmo 0.9.0 (2025-09-15) ============================ Features -------- - Unitful values in headers now carry astropy units and transform under unit transformations (#70) - :py:meth:`with_new_columns ` can now take numpy arrays or astropy quantities (#77) - Add a new "evaluate" method to the standard API, which fills the role of "with_new_columns" for cases when the computation is more than just a simple algebraic combination of columns (#77) - Add "sort_by" to the standard API, which allows ordering by the value of a column. (#112) - Mutli-dimensional columns are now unpacked correctly when only reading a single row - You can now drop entire datasets from a StructureCollection using :py:meth:`with_datasets ` - You can now dump datasets and some data from collections to parquet with :py:meth:`opencosmo.io.write_parquet` - You can now remove datasets from a StructureCollection with :code:`with_datasets` Bugfixes -------- - Fixed a bug that could cause MPI writes to stall after queries that returned small numbers of rows. (#99) - Fixed a bug that could cause printing lightcone summary to fail when column originally contained "redshift" column that had been dropped. (#101) - Fix a bug for installing analysis tools Deprecations and Removals ------------------------- - StructureCollections now always require a dataset be specified when calling :py:meth:`select ` Misc ---- - #106 - Dependency management now handled by UV - Minimum required version of mpi4py has been decreased to match version available in ALCF base python environments. - Parameters accessed through a dataset are now returned as dictionaries - Remove significant amounts of dead code, reorganize for clarity - Replace astropy.table.Table with astropy.table.QTable, which generally handles units much more cleanly - Update evaluate to avoid evaluating first row twice - Update evaluate to respect default parameters opencosmo 0.8.0 (2025-07-22) ============================ Features -------- - StructureCollections now filter out structures with no particles by default (#75) - Columns can now be dropped with `Dataset.drop ` (inverse of "select") (#77) - Data can now be requested from datasets as Numpy arrays (#78) - Data retrieved with the :code:`.data` attribute on datasets are now cached (#78) - Added a new "Lightcone" collection type. - Analysis modules can now be installed with new command line script :code:`opencosmo install` - Data producers can now define user-provided flags that determine which datasets should be loaded in a multiple-dataset or group of files. - The opencosmo.analysis module now includes tools for creating visualizations of halos Bugfixes -------- - StructureCollection and Datasets no longer raises StopIteration error if empty (prints warning) (#84) - Fixed yt interface for gravity-only simulations (#90) Improved Documentation ---------------------- - Add towncrier for automated changelog management Deprecations and Removals ------------------------- - open_linked_files has been depcrecated and will be removed in the future. Use :py:meth:`opencosmo.open` instead. Misc ---- - Add installation from files with multiple datasets - Data opening logic has been rewritten from scratch, singnificantly improving performance when opening many file. - Partitioning in MPI now ignores regions that do not have data - The header reading logic has been generalized to allow more flexibility in defining new data types - Unit handling now supports data stored in conventions other than scalefree
