Unreleased

1.8.3, 26 April 2019

1.8.2, 17 April 2019

  • Removed dependency on lzma (PR #262, @tdhopper)
  • backward compatibility fixes (PR #294, @mpenkov)
  • Minor fixes (PR #291, @mpenkov)
  • Fix #289: the smart_open package now correctly exposes a __version__ attribute
  • Fix #285: handle edge case with question marks in an S3 URL

This release rolls back support for transparently decompressing .xz files, previously introduced in 1.8.1. This is a useful feature, but it requires a tricky dependency. It's still possible to handle .xz files with relatively little effort. Please see the README.rst file for details.

1.8.1, 6 April 2019

smart_open.open

This new function replaces smart_open.smart_open, which is now deprecated. Main differences:

  • ignore_extension → ignore_ext
  • new transport_params dict parameter to contain keyword parameters for the transport layer (S3, HTTPS, HDFS, etc).

Main advantages of the new function:

  • Simpler interface for the user, less parameters
  • Greater API flexibility: adding additional keyword arguments will no longer require updating the top-level interface
  • Better documentation for keyword parameters (previously, they were documented via examples only)

The old smart_open.smart_open function is deprecated, but continues to work as previously.
