This amendment has changed most of the payment process, including bank transfers and credit cards. You can check Magento ForumDev Blog (3D Secure 2.0 changes) to make it more understandable.

So, it is advised to take all the crucial steps for Admin security, including, Two-factor authentication, IP whitelisting, VPN usage, using the distinct location that /Admin, and most importantly, a smart password. The exploitable security issues from this release are stored to 2.2.10,, and, accordingly.

3. Infrastructure Enhancement

Magento considers infrastructure enhancement as the main key point while releasing the new versions. It is because of the fact that it keeps customer retention and satisfaction intact. Including the bug fixes and other essential changes, this release has two striking updates in the infrastructure system.

We have mentioned the feature improvements below:

# Support for the advanced PHP versions

To boost the performance, Magento 2.3.3 supports PHP 7.3.x (tested with 7.3.8) and PHP 7.2.x (tested with 7.2.21). 

# Upgrade to Varnish cache 6.2.0

Varnish cache 6.2.0 is the latest version of the Varnish cache. It is also termed as an HTTP reverse proxy. Varnish cache, as the open-source web application accelerator, aids the users for reconfiguration. The process of reconfiguration is helpful in delivering high-performance content. 

# Update to Zend Framework 2

The components of Zend framework 2 are updated to Active/LTS versions. Check out Support and Long Term Support Policies to attain more knowledge about Zend Framework long-term support policy.

4. Performance Boosts

Turning off the automatic URL rewrite generation is possible for the businesses. This URL happens on the product by default when the intended category is saved. The authentic Generate “product/category” URL Rewrites configuration option verifies this behavior. 

After this feature gets enabled, the Magento creates data while saving the category with several assigned products. 

The performance of Magento can get degraded when the data is saved in the rewrite tables.   

The page load speed improves when the insignificant CSS elements are moved to the bottom of the page. It allows the browser to administer and show a storefront page instantly. The setting gets disable by default. To make it enable, you need to make a navigation towards Stores-> Configuration-> Advanced-> Developer->CSS Settings-> Apply CSS critical path. You can check more information on CSS critical path documentation.

The UI/JQuery library is factorized into different widgets. It is done to load just the widgets they require. Because of this amendment, the performance of the important storefront tasks such as configrable home, product, checkout pages, and loading of a category can be improved. 

It is advised to update the custom storefront code to eliminate the UI/JQuery dependency. Contrarily, get ready to see the performance degradation warning message on the console. 

The store pages present the text in the readable system font comparative to the custom fonts.   It enhances the page load speed, respectively. The businesses that use the large CSS files and other fonts can notice the most considerable growth. 

5. Businesses Tool Improvements

After the consent of the data collection, the data obtained from the Admin will be sent to Adobe Analytics for reporting and analysis. You can check  Store Admin to receive more information. 

6. GraphQL Support

It is the 2015 Facebook query language and the API technology that permits the internet app to transfer the data from the Magento store via small data packets. It allows the user to request and build fewer API requests when required. GraphQL support provides the tools for growth and acts as a flexible and practical approach. Despite the slow network links, it manages to load quicker than the existing Magento 2 APIs.  We have gathered some of the benefits GraphQL attains:

  • The integration of different programming languages is easy with GraphQL.
  • It builds up requests for reading and writing. Also, it lessens the network transfers and permits the enhanced results with the schema evolution. 
  • GraphQL offers one-endpoint (URL) facilities.

7. Declarative DB Schema

Installing and updating the Magento versions with the statement scheme is an effortless task. Earlier, it was required to write the new version of the Magento database script in PHP. Like; Changing the Magento schema with the upgraded schema and install schema is possible with the recent release of Magento. 

Also, a declarative database schema can be practiced to make improvements. Accordingly, when you are uninstalling the module, you are deleting the information. In addition, it aids you to restructure the database and altering XML so that the prior version becomes easy to abate the module. This process mitigates the bugs, improves the effectiveness and promotes growth.

8. Enhancement in UX and UI

Magento 2.3.3 has brought in enhancements in the UX and UI to the backend for the best admin experience. 

# Gain a real understanding for administrative users

The new release has given a new tool basically for the admins. When the update process is completed, the admin (first) logging to the Admin panel will be directed to Allow Admin usage data collection.    And, when the user clicks on the Allow button, the Adobe Analytics will obtain the data from the Admin activity for reporting and analysis.

# Remarkable changes to the UI

As there is an improvement in the performance in the core storefront task, the UI/jQuery library will be factorized in different widgets to core module loaded in the chosen widgets only. In addition, there are several amendments to the functionality/designing of the specific tab, such as the Credit Memo page, Category, Catalog, Admin, and Order. 

9. Multi-Source Inventory (MSI)

It was complicated to operate the stock schema before. Therefore, several channel inventories become challenging to handle. 

The new release, Magento 2.3, has come up with the Multi-source inventory function that permits the users to manage the inventory from different sources for yielding the orders. 

It would be beneficial if you will store your products in a different online store. Also, a new table structure from the database permits you to book inventory.

With MSI, you can gain below benefits:

The latest internet applications accumulate libraries and instruments, such as ReactJs, webpack, GraphQL and Redux to customize the content and the rapid prototyping, local preferences, useful debugging and enhance productivity.

11. Cache Management ACL

Magento encompasses different cache types that are helpful in preventing the effectiveness of the system from the cache invasion. Additionally, the policy of cache flushing will stop checking your online store from the attacks/ threats. 

The percentage of these attacks has risen from some time because of the extended users. That is why Magento 2.3.3 has introduced cache management ACL. It permits the administrator to manage the Magento Background role permissions.
