Performance improvements
This release has been focused on performance improvements of all kinds. Improvements include an average reduction of data transferred per page by up to 43%, removal of JS libraries, and reworking of critical CSS. It includes:
- Lot's of work on removing reflow on page load
- Refactoring of the mailchimp validation JS. This removed a duplicate version of JQuery, saving a good chunk of JS parsing.
- Reoptimisation of images
- Switch lazy loading from a library to the browser
- Move external CSS which was not gziped or minified to the internal project
- Removal of fallback google tag manager stuff
