Magento 2.3.3 Release Notes Magento 2.3.3 Release Notes

The Most Popular Extension Builder for Magento 2

With a big catalog of 224+ extensions for your online store

Many of us must have been looking forward to the release of Magento 2.3.3 for a while, after that of 2.3.2 in late June 2019. What’s new in the latest version of this e-commerce platform that you should notice? What has Adobe done to upgrade Magento in both Commerce and Open Source editions?

According to Magento 2.3.3 release notes, this significant release offers both editions essential updates and changes in the platform, security, and payment methods. Also, the new version is claimed to include more than 170 functional fixes to the core platform and 75 enhancements in the security. Thanks to the enormous community, Magento approved and implemented over 200 contributions to the latest version. These contributions include minor core code fixes and even significant improvements in Inventory Management and GraphQL.

Magento 2.3.3 release date

Magento 2.3.3 was officially released on October 8th (08/10/2019) with the full release notes being published on the same day. The release announcement has been widely spread within the community and immediately become a hot topic for all developers and other Magento geeks/experts to discuss.

Important notice

Before you go deep into what’s interesting in Magento 2.3.3, you should check whether you upgraded to the pre-release version 2.3.2-p1 earlier. If you did, it is highly recommended to upgrade to 2.3.2-p2 as soon as possible if not upgrading to 2.3.3 as that patch did not include critical security fixes. You should go through the Magento DevBlog post Introducing the New Security-only Patch Release for more information.

Other updates, including those in Page Builder, Inventory Management, Progressive Web Application, are perceived independent ones, so these updates are also released separately. Bug fixes for those are well documented independently too.

Magento 2.3.3 new features & updates

Security is enhanced more sustainably

Three main enhancements include:

  • Make core payment methods comply with PSD2
  • 75 important security fixes
  • Critical enhancements in platform security with XSS protection (cross-site scripting) being boosted.

Enhancement #1: PSD2 regulations compliance

With the fact that the Payment Services Directive (PSD) regulations have been applied in the EU, especially when the updated version PSD2 officially goes into effect on September 14th, 2019, Magento has got to take some action accordingly with core payment methods. Specifically, most payment processing involving credit cards or bank transfers that are affected by the regulations have to be compliant with PSD2.

The Braintree payment method is now compliant with PSD2: Braintree transactions are currently verified by native Braintree 3D Secure 2.0 can be verified by 3D Secure through the cardholderAuthentication request field provided by a third-party service provider as CardinalCommerce The PSD2 compliance to the Cybersource and eWay payment methods, however, is put off in this release. You may have to seek extensions to help with the 3D Secure verification.

Enhancement #2: Security & core code fixes

There are 75 security enhancements in total, which are related to XSS (cross-site scripting) and RCE (remote code execution) vulnerabilities.

Upgrades to core platform

These upgrades focus on boosting platform security and supporting to comply with PCI:

  • Magento 2.3.3 supports PHP 7.3.x and PHP 7.2.x
  • Magento 2.3.3 supports Varnish 6.2.0
  • Upgrade Zend Framework 2 components to the Active/LTS versions

Performance boosts

Store admins are now able to turn off the automatic URL rewrite generation occurring by default when the category is saved. Improve storefront loading speed by placing unnecessary CSS elements at the page bottom. However, this feature is not enabled by defaults, and you’ll have to enable it by going to Stores > Configuration > Advanced > Developer > CSS Settings, click Use CSS critical path.

Refactor the jQuery/ui library into widgets, so only needed core modules will be loaded when necessary. Display text in readable system fonts on store pages to increase page loading speed

Enhancements in infrastructure

These improvements are included in the core platform and some modules: Catalog, Sales, Checkout, UrlRewrite, Customer, and Ui. The WYSIWYG editor is upgraded to TinyMCE v. 4.9.5

Improvements in merchant tool

The tracking of user actions and Admin events has been introduced to improve admin user experience. As soon as you upgrade to Magento 2.3.3, if you allow Adobe to collect the data from Admin activity, it will be sent to Adobe Analytics for further analysis and reports. This will probably help understand users as admins so we can expect changes in the next Magento updates.

Improvements in Inventory Management

This enhancement includes many bug fixes. See the release notes here


Magento expanded GraphQL features and enhanced coverage for PayPal integrations, gift card functionality, and store credit. Also, mutations and queries have been implemented to support:

  • Payment process through PayPal Express, Payflow Pro, Link Express Checkout as well as other methods like and Braintree.
