Magento 2.3.3 Release Highlights: What’s new?

It’s been a while since the last release and we’re all too eager to see what Adobe has in store for us regarding their development of the Magento platform—both the Commerce and Open Source edition.

And boy, did they deliver this time with their huge number of changes and fixes in this 2.3.3 Magento release. Within this release alone, there are over 170 functional fixes to the core product and over 75 security changes. And that’s not to mention over 200 contributions of the Magento community members, whose works range from minor code optimization to fundamental changes to features such as Inventory Management and GraphQL.

First-ever security-only patch

Security fixes are now more conveniently accessible. Heeding their userbase, from Magento 2.3.3 onwards Magento will be shipping a security patch along with the official Magento version. This will make it easier for developers whose security concern is of utmost importance to apply security fixes and delay other quality and performance changes to a later time.

As you might notice, the security-only patch is projected to be based on the latest prior version, which will, in turn, enable more flexibility for users. By projecting the update path this way, users will be able to go on without an official path for at least six months.

Magento 2.3.3 release highlights

1. Significant performance improvements

Performance, after all, is what the majority of us are after. Here’s some changes that can radically improve your page’s loading speed:

1.1 Non-critical CSS elements can now be moved to the bottom of the page.

By default, this option is disabled but with Magento 2.3.3, you can now choose to enable it by heading over to Stores > Configuration > Advanced > Developer > CSS Settings > Use CSS critical path. This will move non-critical CSS elements to the bottom of your page, enabling the essential elements of your storefront to be rendered more quickly and in turn driving more revenue to your store.

1.2 While custom fonts are waiting to be loaded, readable system fonts are now displayed instead.

While sounding insignificant, this is actually a major change for stores that use large CSS files and abundant numbers of fonts.

1.3 Refactored jQuery/ui library

The jQuery/ui is now separate widgets that can be selectively loaded by core modules. This will significantly improve the performance of various store features such as the category loading,

2. Major security improvements

Magento 2.3.3, although itself being a minor patch, comes with improvements comparable to that of a major patch. There are over 75 critical security fixes in this patch alone and that’s not to mention other enhancements such as:

2.1 Compatibility changes in accordance with the new PSD (Payment Service Directive) regulation

With the new PSD (also known as PSD2/Revised Payment Service Directive) regulations recently went into effect, affecting almost all transfers involving credit card or banking institutions, it’s no wonder that immediate compatibility changes are called for.
