1.4.0 - May 26, 2016¶
This release adds several new features, fixes numerous small bug-fixes, and improves performance for common use cases. There are some minor breaking changes, but few user are likely to encounter them. The most important changes in this release are:
- There is now a
TableSet.having()method, which behaves similarly to SQL’s
Table.from_csv()is much faster. In particular, the type inference routines for parsing numbers have been optimized.
Table.compute()method now accepts a
replacekeyword which allows new columns to replace existing columns “in place.”” (As with all agate operations, a new table is still created.)
- There is now a
Slugcomputation which can be used to compute a column of slugs. The
Table.rename()method has also added new options for slugifying column and row names.
The complete list of changes is as follows:
- Added a deprecation warning for
patchmethods. New extensions should not use it. (#594)
utils.slugify()to standardize a sequence of strings. (#466)

1.3.0 - February 28, 2016¶
This version implements several new features and includes two major breaking changes.
Please take note of the following breaking changes:
- There is no longer a
Lengthaggregation. The more obvious
Countis now used instead.
- Agate’s replacements for Python’s CSV reader and writer have been moved to the
agate.csvnamespace. To use as a drop-in replacement:
from agate import csv.
The major new features in this release are primarly related to transforming (reshaping) tables. They are:
Table.normalize()for converting columns to rows.
Table.denormalize()for converting rows to columns.
Table.pivot()for generating “crosstabs”.
Table.homogenize()for filling gaps in data series.
Please see the following complete list of changes for a variety of other bug fixes and improvements.
