It featured updates to the user interface with the introduction of Claro and integrated the latest JavaScript libraries such as CKEditor 5. Additionally, some legacy system components were removed, and new components such as PHP 8.1 were adopted to enhance performance and ease of development, making the system faster and more secure. |
| Drupal 11.0 - 2024 | Released in August 2024, Drupal 11 got improvements made to CKEditor integration, a revamp of the Field UI, performance improvements, and revisions for taxonomy terms, and lots more. |
Upgrading to the latest version of Drupal is not just an option for improving site performance; it is a necessity to ensure long-term security and stability. Failing to upgrade exposes the site to serious security issues, as older versions, such as Drupal 7 and 8, stop receiving security updates, leaving them vulnerable to exploits. For instance, attackers may exploit SQL Injection vulnerabilities to steal or delete data, or use Cross-Site Scripting (XSS) to inject malicious code that harms user data. Additionally, the lack of compatibility with the latest security technologies exposes the site to malware attacks and weakens performance, increasing the likelihood of site downtime.
By upgrading Drupal, you gain a more secure environment, faster performance, and compliance with modern security standards, enhancing the site's stability and protecting it from future threats.
The development of security levels in Drupal across various releases has always been a priority to ensure the protection of sites using this system. In each new release, significant improvements were made in terms of security and infrastructure. Here’s a look at how security has evolved across Drupal releases:
User Roles and Permissions System: Drupal 7 introduced a flexible system for managing user roles and permissions, helping to define who can access any part of the site.
Protection Against SQL Injection: Improved defenses against these attacks were implemented using functions and tools designed to handle input data securely.
Form Validation: Enhanced methods for validating user input in forms were introduced to prevent attacks like Cross-Site Scripting (XSS).

Adoption of the Symfony Framework: By using Symfony as a framework, Drupal 8 benefited from the robust security system that this framework provides, including better protection against common attacks like XSS and CSRF (Cross-Site Request Forgery).
RESTful API: Improved security in building interactive APIs allowed developers to configure access and interaction with external applications securely.
Encryption and Improved User Sessions: Enhanced methods for handling user sessions and cookies were introduced, along with advanced encryption techniques.
Removal of Legacy Code: Deprecated codes and technologies from Drupal 8 were eliminated, reducing the likelihood of old vulnerabilities being exploited and facilitating broader security improvements.
Automatic Updates: One of the features that began to gain focus is the ability to update the system automatically, making it easier to receive the latest security updates without significant user intervention.
Compatibility with the Latest PHP Technologies: Drupal 10 supports PHP 8.1, offering additional security enhancements thanks to the security updates available in the latest versions of the PHP programming language.
New Administration Interface: The adoption of Claro as a new administration interface provides a better user experience and higher security, with updates including improved defenses against cyber attacks.
Session and Authentication Security: Improved session management and multi-factor authentication ensure greater protection for user accounts.
Enhanced Security Management:The new Access Policy API allows for more granular control over user actions, enabling access to be determined by various factors like time of day and URL, rather than just roles.
Simplified Customization: While custom access policies still require specific code, the process is more straightforward than in previous Drupal versions, making it easier for developers to implement robust security measures.
These enhancements across the various releases have made Drupal one of the most secure and stable content management systems, ensuring the protection of sites from modern cyber threats.

When considering upgrading between Drupal versions, several aspects must be taken into account to ensure a smooth and successful process. First, compatibility with current add-ons and themes is crucial, as some custom add-ons or themes may not be compatible with new versions, necessitating updates or redevelopment.
Second, a comprehensive assessment of the site's infrastructure, including the database and resources used, should be conducted to ensure its capability to support new updates. It is also advisable to perform complete backups of the site before starting the upgrade and Data Migration process to avoid data loss in case of any issues.
Additionally, a thorough testing plan should be established post-upgrade to ensure that all features function correctly and that performance has not been negatively impacted. It is also important to have a support team ready to address any challenges that may arise after the upgrade, as these challenges may include performance issues or integration with external services.
Finally, it is recommended to review the official documentation and release notes for the new versions, as they contain valuable information about new features, upgrade procedures, and any potential changes in security or performance. By considering these factors, users can successfully upgrade and benefit from the new advantages offered by modern Drupal releases.
With the evolution of the information technology landscape and user needs, the upcoming Drupal releases are expected to include several new updates and enhancements. One of the primary areas of focus will be improving user experience, with expectations for more modern and user-friendly interfaces. There will be a focus on streamlining processes, making it easier for users to navigate and manage content more efficiently.
In terms of performance, significant improvements in loading speed and response times may be anticipated. There will also be an emphasis on performance optimization techniques such as intelligent caching and CDN (Content Delivery Networks) technologies to enhance the speed of supported sites.
In the area of security, new updates are expected to introduce advanced data protection features, including improvements in session management and multi-factor authentication, along with tools for real-time security monitoring.
Furthermore, enhancements in integration with modern technologies like artificial intelligence and machine learning are anticipated, enabling developers to leverage advanced analytics tools to optimize content strategies and user experience.
It is also likely that APIs will be improved to enable better connections with other systems, facilitating developers in building integrated and interactive applications.
Overall, the future holds great potential for Drupal, with many expected updates that will contribute to enhancing security, performance, and overall user experience.
