1.1.0 is a “minor” release; this version is backwards compatible with sites running versions of WooCommerce greater than or equal to v3.0.
No changes were made in this release only to ensure CoCart remains working the same with WooCommerce v3.6 or greater.
My thanks for Andrew Singh and gelaxe for reporting the issue and testing the RC release and thanks to Andy Keith for explaining the change required in his article.
A minor release for CoCart is now available. Now when you clear the cart, the cart in session is also cleared. This release has been tested with the latest versions of WordPress and WooCommerce.
For those who like to install plugins via composer you can now do so for CoCart as I have now added a composer.json file to the repository.
