⦁ Page Builder replaces the TinyMCE editor in the following Admin areas:
i. CMS Page
ii. CMS Block
iii. Category Description
iv. Product Description

Installation, upgrade, deployment-
The bin/Magento setup:db:status command now returns a message indicating that everything is up-to-date after a successful upgrade. Previously, Magento displayed this error: Declarative Schema is not up to date.

Backend-
⦁ The generated System report (System > Support > System Report) is now rendered correctly. Previously, report content was misaligned.
⦁ Magento now turns off validation on the Price field as expected when the Dynamic price setting is enabled during bundle product creation. Previously, Magento threw a validation error when you removed a value from the Price field when the Dynamic price setting was enabled.
⦁ Magento no longer throws an error when an administrator with restricted permissions adds a Product widget to a CMS page in the Admin. Previously, Magento threw this error when the administrator clicked the Save button: We are sorry, an error has occurred while generating the content.

Configurable products-
⦁ Magento no longer duplicates product thumbnails in a product’s image gallery when you click on a product’s configurable options.
⦁ The configuration pop-up that Magento displays when you are editing a configurable product from a wish list now closes as expected when you click the OK button.

Email-
⦁ The password reset link on the Admin reset password page now works as expected. Previously, when a custom template was used for the reset admin password page, Magento displayed this message when an administrator clicked the link inside the email: Your password reset link has expired. This occurred because the custom email template contained the wrong variable for the user ID.
⦁ Sending customer emails from the Admin now works properly when enabled at the store-view level. Previously, Magento did not send customer emails when email notification settings were enabled at the store-view level but not the global level.

Payment Integration-
PayPal Pay Later-
This feature allows shoppers to pay for an order in bi-weekly instalments, instead of paying the full amount at the time of purchase.

Amazon Pay-
The Amazon Pay integration was deprecated and it will be removed in a later Magento 2.4.x release. Magento 2.4.3 and higher will contain only updates for compatibility and fixes for major bugs.

Advantages-
⦁ Stronger Security
⦁ Infrastructure Improvements
⦁ Performance Improvements
