Tablib

Deprecations

- Upcoming breaking change in Tablib 2.0.0: the `Row.lpush/rpush` logic is reversed.
`lpush` is appending while `rpush` and `append` are prepending. The broken behavior
will remain in Tablib 1.x and will be fixed (reversed) in Tablib 2.0.0 (453). If you
count on the broken behavior, please update your code when you upgrade to Tablib 2.x.

Improvements

- Tablib is now able to import CSV content where not all rows have the same
length. Missing columns on any line receive the empty string (226).

Breaking changes

- Dropped Python 2 support
- Dependencies are now all optional. To install `tablib` as before with all
possible supported formats, run `pip install tablib[all]`

Improvements

- Formats can now be dynamically registered through the
`tablib.formats.registry.refister` API (256).
- Tablib methods expecting data input (`detect_format`, `import_set`,
`Dataset.load`, `Databook.load`) now accepts file-like objects in addition
to raw strings and bytestrings (440).

Bugfixes

- Fixed a crash when exporting an empty string with the ReST format (368)
- Error cells from imported .xls files contain now the error string (202)

Deprecations

- The 0.14.x series will be the last to support Python 2

Breaking changes

Bugfixes

- Fixed a regression for xlsx exports where non-string values were forced to
strings (314)
