v1.5.0 (2022-03-23)

* Dropped Python 3.6 support
* Added support for piping into and from an external xz process. Contributed by \ 
@fanninpm.
* Support setting the xz compression level. Contributed by @tsibley.

v1.4.0 (2022-01-14)

Add seek() and tell() to the PipedCompressionReader classes (for Windows \ 
compatibility)

v1.3.0 (2022-01-10)

xopen is now available on Windows (in addition to Linux and macOS).
For greater compatibility with the built-in open() function, xopen() has gained \ 
the parameters encoding, errors and newlines with the same meaning as in open(). \ 
Unlike built-in open(), though, encoding is UTF-8 by default.
A parameter format has been added that allows to force the compression file format.
