* Threadsafe `extract()` function.
* More efficient `.conda` handling.

  compression). (Use `.conda` instead.)

## 1.7.3 (2021-04-12)

### Enhancements

* Python tar extraction now used as a fallback if libarchive fails

### Bug fixes

* Fix binsort's mangling of symlinks
* Fix #71, larger directories fail to extract using libarchive
* When testing that exceptions are raised or archives containing abs paths, first check that such a "broken" archive was created during test setup... otherwise skip the test.
* api.create now raises an error correctly if archive creation failed or extension is not supported.
* Travis CI issue now resolved, mock added as dependency for conda test environments and system dependencies
* Fixed bug where extract parser cli failed due to not having ``out_folder`` attribute.

## 1.7.2 (2020-10-16)

### Enhancements

* add --force to transmute

### Bug fixes

* Do not report symlinks as missing files
* Fixes for --process and --out-folder  #68
* --out-folder: Normalise, expand user-ify and ensure it ends with os.sep

### Contributors

## 1.6.0 (2019-09-20)

### Enhancements

* add a "prefix" keyword argument to the api.extract function.  When combined with dest_dir, the prefix is the base directory, and the dest_dir is the folder name.  dest_dir alone as an abspath is both the base directory and the folder name.

### Bug fixes

* provide a non-ProcessPoolExecutor path when number of processes is 1
* open files to be added to archives in binary mode.  On Windows, the implicit default was text mode, which was corrupting newline data and putting in null characters.
* extraction prefix defaults to the folder containing the specified archive.  This is a behavior change from 1.3.x, which extracted into the CWD by default.
