This release rewrites large portions (of a decidedly small plugin) in order to make maintenance easier moving forwards:
- Added support for the WordPress block editor (a.k.a. Gutenberg) (#10).
- Rewrite the plugin to use proper namespaces (#9).
- Bump the minimum supported PHP version to PHP 7.0 (#8).
- Rewrite the test suite using the WordPress core test suite (#5).
Please note that the minimum supported version is PHP 7.0, though PHP 7.2 or newer is recommended as PHP 7.0 (and the entire PHP 5.x line) have reached end-of-life status.
