Released: 2021-04-14
**Bug fixes:**
* Docs: Fixed description of DictView rich comparison methods. (issue 20)
* Docs: Fixed development status of Pypi package to be Beta.
* Fixed that there is no '__reversed__()' method on dict before Python 3.8.
**Enhancements:**
* Removed dependency to 'six' package.
* Stated the memory and compute overhead of using immutable view classes.
* Added support for hashing, dependent on the hashability of the underlying
collection. (issue 30)
* Added OR (|) operator for DictView on Python 3.9. (issue 38)
* Added tests for pickling DictView. (issue 47)
* Added access to the underlying collections via a property.
* The view classes now use slots for the underlying collection.
This improves performance and reduces the view object memory size from 48
Bytes to 40 Bytes. (issue 51)
**Cleanup:**
* Docs: Simplified the introduction section.
* Docs: Removed INSTALL.md file to avoid duplicate information that can become
inconsistent.
