Magento 2.3.3 Open Source New Updates

With the release of Magento 2.3.3 open source, Magento has made a gargantuan number of updates on the various levels to fix all the vulnerabilities found in Magento 2.3.2.

Magento 2.3.3 Release Notes

  • Page load speed was quite a severe issue in Magento 2.3.2 which has been fixed in Magento 2.3.3 version by moving the superfluous CSS elements to the bottom of the page. It is a disabled setting by default. However, you can enable it using Stores > Configuration > Advanced > Developer > CSS Settings > Use CSS critical path.
  • To ensure core modules load only those widgets they need, the jQuery library has been refactored into separate widgets. This upgrade will amplify the performance of the core storefront tasks by leaps and bounds.
  • Now, merchants can control the automatic URL rewrite generation aspect in Magento 2.3.3 instance. When this feature is active, Magento generates a massive amount of data for assigned products. This unsolicited data is saved into rewrite tables that actually dwindle the Magento performance.
  • The text on store pages displays in readable fonts while loading custom fonts, which augments the overall page load speed.

4. Merchant Tool Enhancements

This is unquestionably one of the most intriguing aspects of Magento 2.3.3 open source release notes.

The ultimate aim of any Merchant is to delivering par excellent user experience to its customers. And that is only possible either by tracking your users’ behavior or by improvising the quality and design of your products.

Magento has made a massive change in the Magento shipping attribute. Earlier, it was possible for merchants to create the Magento shipping account. However, that’s not possible anymore because of the drastic shutdown of Tornado (the technology behind Magento shipping). The new-shipping implementations have been done in Magento 2.3.3 which includes –
