4.0.0 (2024-11-19)

Feature

  • Switch default ASDF standard to 1.6.0. (#1744)
  • Raise RuntimeError if a Convert subclass supports multiple tags but doesn't implement select_tag. (#1853)

General

  • Set memmap=False to default for asdf.open and AsdfFile.__init__. (#1801)

Removal

  • remove copy_arrays (replaced by memmap) (#1800)
  • Remove deprecated API. See docs for full details. (#1852)
  • Switch default convert_unknown_ndarray_subclasses to False and issue deprecation warning if it is enabled. (#1858)

3.5.0 (2024-10-02)

Bugfix

  • Allow asdf.util.load_yaml to handle recursive objects (#1825)

Doc

  • added issue links to changelog entries (#1827)
  • Change asdf standard changelog entries to notes to ease transition to towncrier (#1830)

General

  • fix changelog checker to remove brackets (#1828)

Removal

  • Deprecate ignore_version_mismatch. This option has done nothing since asdf 3.0.0 and will be removed in an upcoming asdf version (#1819)

3.4.0 (2024-08-04)

  • Fix issue where roundtripping a masked array with no masked values removes the mask [#1803]
  • Use a custom exception AsdfSerializationError to indicate when an object in the tree fails to be serialized by asdf (and by yaml). This exception currently inherits from yaml.representer.RepresenterError to provide backwards compatibility. However this inheritance may be dropped in a future asdf version. Please migrate to the new AsdfSerializationError. [#1809]
  • Drop importlib_metadata as a dependency on Python 3.12 and newer [#1810]

  • Ensure that top-level accesses to the tree outside a closed context handler result in an OSError. [#628]
  • Fix the way generic_io handles URIs and paths on Windows. [#632]
  • Fix bug in asdftool that prevented extract command from being visible. [#633]

2.3.0 (2018-11-28)

Note

The ASDF Standard is at v1.3.0

  • Storage of arbitrary precision integers is now provided by asdf.IntegerType. Reading a file with integer literals that are too large now causes only a warning instead of a validation error. This is to provide backwards compatibility for files that were created with a buggy version of ASDF (see #553 below). [#566]
  • Remove WCS tags. These are now provided by the gwcs package. [#593]
  • Deprecate the asdf.asdftypes module in favor of asdf.types. [#611]
  • Support use of pathlib.Path with asdf.open and AsdfFile.write_to. [#617]
  • Update ASDF Standard submodule to version 1.3.0.

2.2.1 (2018-11-15)

  • Fix an issue with the README that caused sporadic installation failures and also prevented the long description from being rendered on pypi. [#607]

2.2.0 (2018-11-14)

  • Add new parameter lazy_load to AsdfFile.open. It is True by default and preserves the default behavior. False detaches the loaded tree from the underlying file: all blocks are fully read and numpy arrays are materialized. Thus it becomes safe to close the file and continue using AsdfFile.tree. However, copy_arrays parameter is still effective and the active memory maps may still require the file to stay open in case copy_arrays is False. [#573]
  • Add AsdfConversionWarning for failures to convert ASDF tree into custom types. This warning is converted to an error when using assert_roundtrip_tree for tests. [#583]
  • Deprecate asdf.AsdfFile.open in favor of asdf.open. [#579]
  • Add readonly protection to memory mapped arrays when the underlying file handle is readonly. [#579]

2.1.2 (2018-11-13)

  • Make sure that all types corresponding to core tags are added to the type index before any others. This fixes a bug that was related to the way that subclass tags were overwritten by external extensions. [#598]

2.1.1 (2018-11-01)

  • Make sure extension metadata is written even when constructing the ASDF tree on-the-fly. [#549]
  • Fix large integer validation when storing numpy integer literals in the tree. [#553]
  • Fix bug that caused subclass of external type to be serialized by the wrong tag. [#560]
  • Fix bug that occurred when attempting to open invalid file but Astropy import fails while checking for ASDF-in-FITS. [#562]
  • Fix bug that caused tree creation to fail when unable to locate a schema file for an unknown tag. This now simply causes a warning, and the offending node is converted to basic Python data structures. [#571]

2.1.0 (2018-09-25)

  • Add API function for retrieving history entries. [#501]
  • Store ASDF-in-FITS data inside a 1x1 BINTABLE HDU. [#519]
  • Allow implicit conversion of namedtuple into serializable types. [#534]
  • Fix bug that prevented use of ASDF-in-FITS with HDUs that have names with underscores. [#543]
  • Add option to generic_io.get_file to close underlying file handle. [#544]
  • Add top-level keys method to AsdfFile to access tree keys. [#545]

2.0.3 (2018-09-06)

  • Update asdf-standard to reflect more stringent (and, consequently, more correct) requirements on the formatting of complex numbers. [#526]
  • Fix bug with dangling file handle when using ASDF-in-FITS. [#533]
  • Fix bug that prevented fortran-order arrays from being serialized properly. [#539]

2.0.2 (2018-07-27)

  • Allow serialization of broadcasted numpy arrays. [#507]
  • Fix bug that caused result of set_array_compression to be overwritten by all_array_compression argument to write_to. [#510]
  • Add workaround for Python OSX write limit bug (see https://bugs.python.org/issue24658). [#521]
  • Fix bug with custom schema validation when using out-of-line definitions in schema file. [#522]

2.0.1 (2018-05-08)

  • Allow test suite to run even when package is not installed. [#502]

2.0.0 (2018-04-19)

  • Astropy-specific tags have moved to Astropy core package. [#359]
  • ICRSCoord tag has moved to Astropy core package. [#401]
  • Remove support for Python 2. [#409]
  • Create pytest plugin to be used for testing schema files. [#425]
  • Add metadata about extensions used to create a file to the history section of the file itself. [#475]
  • Remove hard dependency on Astropy. It is still required for testing, and for processing ASDF-in-FITS files. [#476]
  • Add command for extracting ASDF extension from ASDF-in-FITS file and converting it to a pure ASDF file. [#477]
  • Add command for removing ASDF extension from ASDF-in-FITS file. [#480]
  • Add an ExternalArrayReference type for referencing arrays in external files. [#400]
  • Improve the way URIs are detected for ASDF-in-FITS files in order to fix bug with reading gzipped ASDF-in-FITS files. [#416]
  • Explicitly disallow access to entire tree for ASDF file objects that have been closed. [#407]
  • Install and load extensions using setuptools entry points. [#384]
  • Automatically initialize asdf-standard submodule in setup.py. [#398]
  • Allow foreign tags to be resolved in schemas and files. Deprecate tag_to_schema_resolver property for AsdfFile and AsdfExtensionList. [#399]
  • Fix bug that caused serialized FITS tables to be duplicated in embedded ASDF HDU. [#411]
  • Create and use a new non-standard FITS extension instead of ImageHDU for storing ASDF files embedded in FITS. Explicitly remove support for the .update method of AsdfInFits, even though it didn't appear to be working previously. [#412]
  • Allow package to be imported and used from source directory and builds in development mode. [#420]
  • Add command to asdftool for querying installed extensions. [#418]
  • Implement optional top-level validation pass using custom schema. This can be used to ensure that particular ASDF files follow custom conventions beyond those enforced by the standard. [#442]
  • Remove restrictions affecting top-level attributes data, wcs, and fits. Bump top-level ASDF schema version to v1.1.0. [#444]

1.3.3 (2018-03-01)

  • Update test infrastructure to rely on new Astropy v3.0 plugins. [#461]
  • Disable use of 2to3. This was causing test failures on Debian builds. [#463]

1.3.2 (2018-02-22)

  • Updates to allow this version of ASDF to be compatible with Astropy v3.0. [#450]
  • Remove tests that are no longer relevant due to latest updates to Astropy's testing infrastructure. [#458]

1.3.1 (2017-11-02)

  • Relax requirement on semantic_version version to 2.3.1. [#361]
  • Fix bug when retrieving file format version from new ASDF file. [#365]
  • Fix bug when duplicating inline arrays. [#370]
  • Allow tag references using the tag URI scheme to be resolved in schema files. [#371]

1.3.0 (2017-10-24)

  • Fixed a bug in reading data from an "http:" url. [#231]
  • Implements v 1.1.0 of the asdf schemas. [#233]
  • Added a function is_asdf_file which inspects the input and returns True or False. [#239]
  • The open method of AsdfInFits now accepts URIs and open file handles in addition to HDULists. The open method of AsdfFile will now try to parse the given URI or file handle as AsdfInFits if it is not obviously a regular ASDF file. [#241]
  • Updated WCS frame fields obsgeoloc and obsgeovel to reflect recent updates in astropy that changed representation from Quantity to CartesianRepresentation. Updated to reflect astropy change that combines galcen_ra and galcen_dec into galcen_coord. Added support for new field galcen_v_sun. Added support for required module versions for tag classes. [#244]
  • Added support for lz4 compression algorithm [#258]. Also added support for using a different compression algorithm for writing out a file than the one that was used for reading the file (e.g. to convert blocks to use a different compression algorithm) [#257]
  • Tag classes may now use an optional supported_versions attribute to declare exclusive support for particular versions of the corresponding schema. If this attribute is omitted (as it is for most existing tag classes), the tag is assumed to be compatible with all versions of the corresponding schema. If supported_versions is provided, the tag class implementation can include code that is conditioned on the schema version. If an incompatible schema is encountered, or if deserialization of the tagged object fails with an exception, a raw Python data structure will be returned. [#272]
  • Added option to AsdfFile.open to allow suppression of warning messages when mismatched schema versions are encountered. [#294]
  • Added a diff tool to asdftool to allow for visual comparison of pairs of ASDF files. [#286]
  • Added command to asdftool to display available tags. [#303]
  • When possible, display name of ASDF file that caused version mismatch warning. [#306]
  • Issue a warning when an unrecognized tag is encountered. [#295] This warning is silenced by default, but can be enabled with a parameter to the AsdfFile constructor, or to AsdfFile.open. Also added an option for ignoring warnings from unrecognized schema tags. [#319]
  • Fix bug with loading JSON schemas in Python 3.5. [#317]
  • Remove all remnants of support for Python 2.6. [#333]
  • Fix issues with the type index used for writing out ASDF files. This ensures that items in the type index are not inadvertently overwritten by later versions of the same type. It also makes sure that schema example tests run against the correct version of the ASDF standard. [#350]
  • Update time schema to reflect changes in astropy. This fixes an outstanding bug. [#343]
  • Add copy_arrays option to asdf.open to control whether or not underlying array data should be memory mapped, if possible. [#355]
  • Allow the tree to be accessed using top-level __getitem__ and __setitem__. [#352]

1.2.1 (2016-11-07)

  • Make asdf conditionally dependent on the version of astropy to allow running it with older versions of astropy. [#228]

  • Forced new blocks to be contiguous [#221]
  • Rewrote code which tags complex objects [#223]
  • Fixed version error message [#224]
