Fixes:

1.0.1 - December 29, 2016

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

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 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, who has almost single-handedly kept the csvkit fire burning for a year. Thanks, James!

Backwards-incompatible changes:

  • :doc:`/scripts/csvjoin` now renames duplicate columns with integer suffixes to prevent collisions in output.
  • :doc:`/scripts/csvsql` now generates DateTime columns instead of Time columns.
  • :doc:`/scripts/csvsql` now generates Decimal columns instead of Integer, BigInteger, and Float columns.
  • :doc:`/scripts/csvsql` no longer generates max-length constraints for text columns.
  • The --doublequote long flag is gone, and the -b short flag is now an alias for --no-doublequote.
  • When using the --columns or --not-columns options, you must not have spaces around the comma-separated values, unless the column names contain spaces.
  • When sorting, null values are now greater than other values instead of less than.
  • CSVKitReader, CSVKitWriter, CSVKitDictReader, and CSVKitDictWriter have been removed. Use agate.csv.reader, agate.csv.writer, agate.csv.DictReader and agate.csv.DictWriter.
  • Drop Python 2.6 support (end-of-life was October 29, 2013).
  • Drop support for older versions of PyPy.
  • If --no-header-row is set, the output will have column names a, b, c, etc. instead of column1, column2, column3, etc.
  • csvlook renders a simpler, markdown-compatible table.
