2.0.0 - May 1, 2024

Want to use csvkit programmatically? Check out `agate <https://agate.readthedocs.io/en/latest/>`__, used internally by csvkit.

**BACKWARDS-INCOMPATIBLE CHANGES:**

-  :doc:`/scripts/csvclean` now writes its output to standard output and its errors to standard error, instead of to ``basename_out.csv`` and ``basename_err.csv`` files. Consequently:

   -  The :code:`--dry-run` option is removed. The :code:`--dry-run` option changed error output from the CSV format used in ``basename_err.csv`` files to a prosaic format like ``Line 1: Expected 2 columns, found 3 columns``.
   -  Summary information like ``No errors.``, ``42 errors logged to basename_err.csv`` and ``42 rows were joined/reduced to 24 rows after eliminating expected internal line breaks.`` is not written.

-  :doc:`/scripts/csvclean` no longer reports or fixes errors by default; it errors if no checks or fixes are enabled. Opt in to the original behavior using the :code:`--length-mismatch` and :code:`--join-short-rows` options. See new options below.
-  :doc:`/scripts/csvclean` no longer omits rows with errors from the output. Opt in to the original behavior using the :code:`--omit-error-rows` option.
-  :doc:`/scripts/csvclean` joins short rows using a newline by default, instead of a space. Restore the original behavior using the :code:`--separator " "` option.

In brief, to restore the original behavior for :doc:`/scripts/csvclean`:

.. code-block:: bash

   csvclean --length-mismatch --omit-error-rows --join-short-rows --separator " " myfile.csv

Other changes:

-  feat: :doc:`/scripts/csvclean` adds the options:

   -  :code:`--length-mismatch`, to error on data rows that are shorter or longer than the header row
   -  :code:`--empty-columns`, to error on empty columns
   -  :code:`--enable-all-checks`, to enable all error reporting
   -  :code:`--omit-error-rows`, to omit data rows that contain errors, from standard output
   -  :code:`--label LABEL`, to add a "label" column to standard error
   -  :code:`--header-normalize-space`, to strip leading and trailing whitespace and replace sequences of whitespace characters by a single space in the header
   -  :code:`--join-short-rows`, to merge short rows into a single row
   -  :code:`--separator SEPARATOR`, to change the string with which to join short rows (default is newline)
   -  :code:`--fill-short-rows`, to fill short rows with the missing cells
   -  :code:`--fillvalue FILLVALUE`, to change the value with which to fill short rows (default is none)

-  feat: The :code:`--quoting` option accepts 4 (`csv.QUOTE_STRINGS <https://docs.python.org/3/library/csv.html#csv.QUOTE_STRINGS>`__) and 5 (`csv.QUOTE_NOTNULL <https://docs.python.org/3/library/csv.html#csv.QUOTE_NOTNULL>`__) on Python 3.12.
-  feat: :doc:`/scripts/csvformat`: The :code:`--out-quoting` option accepts 4 (`csv.QUOTE_STRINGS <https://docs.python.org/3/library/csv.html#csv.QUOTE_STRINGS>`__) and 5 (`csv.QUOTE_NOTNULL <https://docs.python.org/3/library/csv.html#csv.QUOTE_NOTNULL>`__) on Python 3.12.
-  fix: :doc:`/scripts/csvformat`: The :code:`--out-quoting` option works with 2 (`csv.QUOTE_NONUMERIC <https://docs.python.org/3/library/csv.html#csv.QUOTE_NOTNUMERIC>`__). Use the :code:`--locale` option to set the locale of any formatted numbers.
-  fix: :doc:`/scripts/csvclean`: The :code:`--join-short-rows` option no longer reports length mismatch errors that were fixed.

1.5.0 - March 28, 2024
----------------------

-  feat: Add support for Zstandard files with the ``.zst`` extension, if the ``zstandard`` package is installed.

1.4.0 - February 13, 2024
-------------------------

-  feat: :doc:`/scripts/csvpy` adds the options:

   -  :code:`--no-number-ellipsis`, to disable the ellipsis (``…``) if max precision is exceeded, for example, when using ``table.print_table()``
   -  :code:`--sniff-limit``
   -  :code:`--no-inference``

-  feat: :doc:`/scripts/csvpy` removes the :code:`--linenumbers` and :code:`--zero` output options, which had no effect.
-  feat: :doc:`/scripts/in2csv` adds a :code:`--reset-dimensions` option to `recalculate <https://openpyxl.readthedocs.io/en/stable/optimized.html#worksheet-dimensions>`_ the dimensions of an XLSX file, instead of trusting the file's metadata. csvkit's dependency `agate-excel <https://agate-excel.readthedocs.io/en/latest/>`_ 0.4.0 automatically recalculates the dimensions if the file's metadata expresses dimensions of "A1:A1" (a single cell).
-  fix: :doc:`/scripts/csvlook` only reads up to :code:`--max-rows` rows instead of the entire file.
-  fix: :doc:`/scripts/csvpy` supports the existing input options:

-  fix: Reconfigure the encoding of standard input according to the :code:`--encoding` option, which defaults to ``utf-8-sig``. Affected users no longer need to set the ``PYTHONIOENCODING`` environment variable.
-  fix: Prompt the user if additional input is expected (i.e. if no input file or piped data is provided) in :doc:`/scripts/csvjoin`, :doc:`/scripts/csvsql` and :doc:`/scripts/csvstack`.

1.0.1 - December 29, 2016

This is a minor release which fixes several bugs reported in the :code:`1.0.0` release earlier this week. It also significantly improves the output of :doc:`/scripts/csvstat` and adds a :code:`--csv` output option to that command.

-  :doc:`/scripts/csvstat` no longer crashes when a :code:`Number` column has :code:`None` as a frequent value. (#738)

-  Update required version of unittest to latest. (#727)

1.0.0 - December 27, 2016
-------------------------

This is the first major release of csvkit in a very long time. The entire backend has been rewritten to leverage the `agate <https://agate.rtfd.io>`_ data analysis library, which was itself inspired by csvkit. The new backend provides better type detection accuracy, as well as some new features.

Because of the long and complex cycle behind this release, the list of changes should not be considered exhaustive. In particular, the output format of some tools may have changed in small ways. Any existing data pipelines using csvkit should be tested as part of the upgrade.

Much of the credit for this release goes to `James McKinney <https://github.com/jpmckinney>`_, who has almost single-handedly kept the csvkit fire burning for a year. Thanks, James!

Backwards-incompatible changes:

-  Drop Python 2.6 support (end-of-life was October 29, 2013).
-  Drop support for older versions of PyPy.
