Magento 2.4.3 Releases: Get Ready to Upgrade Your Online Store with New Features

Alekh Verma | July 14, 2023

On August 10, 2021, Magento and Adobe Commerce released Magento Open Source 2.4.3 version with over 370 new fixes to core code and 33 security enhancements.

The latest Magento 2.4.3 comes with various enhancements to performance and security which includes the solutions of almost 290 GitHub issues raised by the developer community and all known issues identified in Magento 2.4.2.

If you have an online store on Magento website, you would be probably gearing up for the peak of sales in 2021. With the release of Magento 2.4.3, businesses will now have better features and opportunities to make more sales during the upcoming shopping season.

The latest Magento version offers many new features that will enable online stores to provide a great on-site shopping experience to customers.

In this post, eSearch Logix will tell you about the new features and updates of Magento 2.4.3 that could help you to upgrade your online store and thus improve sales.

Key Features of Magento 2.4.3 


All the known issues found in the previous Magento 2.4.2 version have been fixed in this release. Moreover, 33 additional security improvements have been made to close Remote Code Execution (RCE) and cross-site scripting (XSS) vulnerabilities.

In case you can’t upgrade to the latest Magento version quickly, it is recommended to install at least one of the security patch versions which are given below:

  • Adobe Commerce 2.4.2-p2
  • Adobe Commerce 2.3.7-p1


Rate limiting is now built in to Magento APIs to stop denial-of-service (DoS) attacks. Web APIs now imposes restrictions on the size or number of resources (the default limit is set to 20 and can be configured to a different value based on business need) which can be requested by a client.


With the expansion of ReCAPTCHA, your eCommerce websites are much safer from spam and bots. It protects online stores from carding attacks through brute force mechanisms. When web APIs are accessed by a third-party integration service which uses OAuth, ReCAPTCHA is disabled as default. Though it can be enabled from the admin panel.


This release includes enhancements that refine the quality of the framework and the following functional areas:

  • CMS
  • Import/Export
  • OMS
  • Cart and Checkout
  • B2B
  • Customer account
  • Catalog
  • Staging and Preview
  • Promotions and Targeting


This new feature is now supported in deployments which contain PayPal. It allows shoppers to pay for an order in bi-weekly installments, instead of paying the full amount at the time of purchase.


Adobe commerce has provided a new composer plugin which performs integrity checks during installation to eliminate the vulnerability known as dependency confusion. It will help Magento website developers to use private and public composer package repositories to deliver code for updates or fixes to Adobe Commerce and Magento Open Source merchants.

This private composer package repository at is audited by Adobe for malware and package upload validation.

However, a non-used namespace at the public repository at can be utilized to upload malicious packages, which in turn can be passed on to the merchant's commerce instances. Here are the techniques to avoid dependency confusion:

  • Ensure the namespace on is owned by you.
  • Use the plugin during testing any extension's installation flow.


Magento 2.4.3 is not compatible with PHP 8.x yet; however, the following platform upgrades take one step closer to future compatibility with PHP 8.x.

  • The knockout library has been upgraded to v3.5.1 (the latest version)
  • Core composer dependencies and third-party libraries have been advanced to the latest version which is compatible with PHP 8.x.
  • Laminas library dependencies have been upgraded to PHP 8.x.-compatible versions. Some redundant dependencies have been removed from the composer.json file. For this purpose, Adobe Commerce 2.4.3 uses Laminas 3.4.0.

This is one of the hot features of Magento 2.4.3 powered by Adobe Sensei. Live Search provides an improved search experience by using artificial intelligence and machine learning algorithms. With Live Search you get:

  • Flexible framework with full GraphQL coverage, API sandbox environments, and Ultrafast SaaS.
  • Lower TCO reduces the cost of ownership which drives the cost of development of website search solutions.
  • AI-powered tools increase conversions by empowering Adobe Sensei and improve overtime with commerce data.
  • Rich search experience enables shoppers to discover what they want with as minimal effort as possible.


GraphQL support has been extended with the following features:

  1. Shared catalogs
  2. Negotiable quotes
  3. Shared routes
  4. Wish lists
  5. Gift registries
    5.1 Share a gift registry with invitees
    5.2 Search by email, type, or ID
    5.3 Create, delete or update gift registries
    5.4 Add, update, or remove the cart to the gift registry
    5.5 Move all items from the cart to the gift registry
    5.6 Update or remove items from a gift registry


The updated version of Magento B2B has been released along with Magento 2.4.3 with the following added features:

  1. Store owners can now edit and update customer custom attribute values.
  2. Send emails on soon-t-expire and expired negotiable quotes.
  3. Admins with restricted accounts which include only website-level privileges can now create a company which uses a different currency than the website.


Page Builder is now available as a bundled extension in Magento Open Source. It is the default content editing tool for Adobe Commerce 2.4.3 and Magento Open Source 2.4.3. It can replace the WYSIWG editor with any third-party module. Page Builder replaces the TinyMCE editor in the below admin areas:

  • Product Description
  • Category Description
  • CMS Block
  • CMS Page

12. PWA Studio

PWA (Progressive Web Applications) Studio is another great addition to the Shopper's wishlist. Shoppers can now smoothly save and track items by adding products to their wishlist directly from category pages and the cart page.

Buying from a wishlist is now simplified with the capability to add to a cart directly from a wishlist. These enhancements highly encourage conversions on eCommerce websites.

Adobe Commerce has also introduced a user interface (UI) kit along with PWA Studio. The kit comes with pre-configured assets, templates, and symbols for creating an intuitive and mobile-first web experience. It supports developers in creating responsive eCommerce website design that support multiple mobile operating systems and increase sales.

13. Upgrade Compatibility Tool  

Adobe has increased the scope of the upgrade compatibility tool, originally released in January as an Alpha, with a goal to improve its usability and workflow. It enables merchants to detect and validate core files modifications, export the report in a .json file, validate Vendor Bundled Extensions (VBEs) like Vertex and dotdigital, and see error codes to identify and resolve issues.

14. Observation for Adobe Commerce

Observation for Adobe Commerce is a monitoring tool available to cloud users. This tool visually showcases application log data in combination with data from the New Relic observability platform on a single pane of glass with an easy-to-understand dashboard.

It collects your commerce data to recognize key signals against a common timeline that can be expanded or contracted, allowing you to visualize your log data to improve performance management and issue resolution. You can spend your time correlating events and errors to gain deep insights into the causes of performance bottlenecks, instead of tracking disparate data.
