Authored by Ameex Technologies on 11 Mar 2021

The new version of Magento open-source and commerce is here and with some exciting new things and improvements. This new release has all the previous Magento 2.3.6-p1 and Magento 2.4.2 code and 30 security enhancements. The new version also introduces support for PHP 7.4, MySQL 8.0, and Elasticsearch 7.6.x.

Below are some reasons and important features of Magento 2.4:

1. Security Enhancements

This release has more than 30 security fixes and platform security improvements. Some of those are:

  • Two-factor authentication is enabled by default from the admin end, and it cannot be disabled. Admin must configure 2FA to log into the admin.
  • Template filter strict mode is enabled by default. Easy for the developers when coding email templates.
  • Data rendering for UI data providers is now disabled by default. This will prevent malicious users from executing arbitrary JavaScript which ensures that the store is secure.
  • Content security policy improvements

2. Platform Upgrades

  • Magento 2.4 supports only PHP 7.4. PHP 7.1 & PHP 7.2 are deprecated. This enhances the core strength of the platform. All the benefits of PHP 7.4 are in Magento 2.4.
  • Elasticsearch 7.6.x is the default catalog search engine for both Magento commerce and open-source which has a robust search feature. Magento 2.4 cannot be installed without also installing Elastic Search 7.6.x. MySQL search engine has been removed completely.
  • Support for MySQL 8.0. Although MySQL 5.7 is supported also by Magento 2.4. It is recommended to migrate to MySQL 8.0 for improved performance, security, and reliability.
  • Support for Maria DB 10.4. Maria DB 10.0 and 10.1 are no longer supported. It is recommended to upgrade to Maria DB 10.4 if you are running on Maria DB 10.2.
  • Migration of dependencies on the Zend Framework to Laminas Project
  • Signifyd fraud core integration is removed. However, Signifyd users can download the extension from the marketplace for free.

3. Infrastructure Improvements

  • Core Integration of third-party payment methods is removed that includes Authorize.Net, Braintree, eWay, CyberSource, and Worldpay payment methods. Merchants should migrate to official Marketplace extensions.
  • Support for partial word search for default Elasticsearch. Easier for the user to search with any part of the word.
  • PayPal JavaScript SDK is upgraded.
  • Web Setup Wizard is deprecated and removed.
  • Composer update plugin.

4. Performance Improvements

  • Improvements to customer data section invalidation logic.
  • Multiple optimizations to Redis performance.

            a. Decrease in the size of network data transfers between Redis and Magento.
            b. Reduction in Redis’ consumption of CPU cycles by improving the adapter’s ability to automatically                                                                 determine what needs to be loaded.
            c. Reduction in race conditions on Redis write operations.
            d. Redis interruption is handled better, and logs are created in the exception log.

  • Caching of results of SQL queries to inventory tables is improved. Instead of 16 Queries it is now 1 Query.
  • 25% to 30% improvement in quick add-to-cart performance.
  • Images can be loaded using Lazy load. This will ensure that offscreen images are loaded when the view is reached. This improves page load times.

Performance Improvements

Administrators can now search, filter, and sort images 30x faster than the earlier version. UI is improved and integrated with Adobe Stock.

6. Inventory Management

Support for in-store pickup and bundle products supports multi-store mode. numerous bug fixes

9. Fixed Issues

  • Website can be removed along with website-related configuration.
  • Configuration settings disabled in index.php are no longer editable from Admin.
  • When store configuration is created in config.php then stores can be created without any issue.
  • Data scripts are run only once when the setup upgrade command is run.
  • It is always recommended that we should have the Magento version up to date to make eCommerce sites secured, run faster, and keep them bug-free.

Furthermore, Two-Factor Authentication is introduced in the latest version which boosts security. The Commerce edition boasts New Order Approval flow as a B2B enhancement.

In addition to that, payment methods such as Authorise.Net and Braintree are removed in this Magento version for Open Source. For Commerce edition, eWay, CyberSource, and Worldpay are removed from the Magento core. However, if merchants want to use these payment options, they will need to install the official extensions available on Magento Marketplace.
