v 1.1.0-beta1

> released 2020-12-21

**NOTE:**
This is a bug fix release, not a feature release. The minor version number
was incremented due to the following changes:

* Ported build system to CMake.
* Ported test suite to Catch2.
* Build requires C++11 compiler support.
* Tests require C++17 compiler support.
* Moved to the Semantic Versioning Specification: https://semver.org
  * Public include directories have been renamed from `${lib}-${major}.${minor}`
    to `${lib}-${major}` due to having the minor version (always having been 0
    in this case) in the public interface being unreasonable when using semantic
    versioning. Symbolic links are provided for backwards compatibility, though.
* Moved the project from launchpad to github:
    * Source: https://github.com/m6w6/libmemcached
    * Documentation: https://m6w6.github.io/libmemcached
    * Continuous Integration:
        * Github: https://github.com/m6w6/libmemcached/actions (Linux, MacOS, Windows **·** amd64)
