 Timeline of Sitefinity CMS version history and release dates.


Key Features of Recent Major Sitefinity CMS Releases

Sitefinity 14.4: A Milestone in .NET Core Integration

Sitefinity 14.4 marked a significant stride in web development and features key advancements that empower users. One of the advancements includes a decoupled .NET Core front-end to enhance flexibility and enable seamless integration with modern technologies. The revamped Page Builder offers intuitive content creation to streamline the design process for engaging and dynamic web pages.

This release aligns with the latest technologies by incorporating support for .NET 7, thereby ensuring compatibility and future-proofing websites. The page editor navigation tree has undergone enhancements to its design to provide an even more user-friendly experience. The improved navigation streamlines content management, simplifying the process of organizing and visualizing the site structure for users.

Sitefinity 15.0: Redefining User Experience and AI Integration

In addition to the revamped user dashboard, Sitefinity 15.0 introduces an array of user-centric features to enrich the overall experience. The redesigned dashboard in Angular not only enhances aesthetics but also significantly improves responsiveness, ensuring a faster and more efficient initial interaction with the Sitefinity application. Users can now enjoy a more intuitive and personalized experience through the incorporation of additional predefined widgets on the dashboard, offering at-a-glance insights into crucial metrics. The new page editor extends its functionality to the dashboard, allowing users to customize and tailor the layout according to their specific needs, fostering a dynamic and adaptable workspace.

Additionally, Sitefinity now has out-of-the-box integration with the Azure OpenAI Service, which enables editors to efficiently optimize and personalize existing content to suit the needs and requirements of different personas. Content editors can use artificial intelligence (AI) tools straight from their WYSIWYG (what-you-see-is-what-you-get) editors without learning how to write prompts or switch interfaces. This is available via the new AI menu in the content editing toolbar of the text editor, enabling users to generate, summarize, improve, or personalize text content through guided dialogues. Finally, administrators can change the prompt that is sent to the AI service and optionally, add new actions to the AI dropdown menu.

Sitefinity Life Cycle Phases

The Sitefinity Product Life Cycle encompasses General Availability (GA) to Retirement, with three main phases: Active, Sunset, and Retired.

The Active phase, starting with GA, ensures full support and regular bugfix updates for all subscribers. While bugfix updates for the latest version are bi-weekly, older Active versions receive updates with a reduced frequency. In case of issues, Progress collaborates with customers under a Maintenance and Support Contract, with the option to recommend upgrading to a recent version.

The Sunset phase provides technical support and critical updates. However, updates during this phase focus solely on bugfixes without introducing new features.

Once a version enters the Retired phase, Progress holds no obligation for updates, though efforts are made for customers with Maintenance and Support contracts. Retired products lack guaranteed security updates, emphasizing the strong recommendation to upgrade. 

Sitefinity Regular and LTS Releases

Sitefinity offers Regular and Long Term Supported (LTS) releases designed to cater to the diverse needs of enterprise customers. Regular releases provide frequent updates and feature enhancements, ensuring enterprises stay at the forefront of technology. These releases are ideal for those seeking the latest innovations and improvements.

On the other hand, LTS releases focus on stability and long-term support, providing a reliable foundation for mission-critical systems. This ensures extended support and security updates, offering a strategic choice for enterprises that prioritize a stable and secure environment over frequent feature changes. The flexibility to choose between Regular and LTS releases empowers enterprises to align their CMS strategy with specific business objectives and preferences.

Importance of Upgrading to Supported Versions

Upgrading Sitefinity provides numerous benefits that are crucial for a seamless digital experience. The latest versions ensure an intuitive, user-friendly interface to enhances the user experience. As an enterprise-grade development platform, upgrades introduce advanced features and improvements, bolstering the website's capabilities. Streamlined management becomes a reality with upgraded versions, simplifying content creation and administration. Additionally, flexible deployment options are unlocked, allowing businesses to adapt to evolving needs efficiently.

Using retired or unsupported versions poses inherent risks. Security vulnerabilities may persist without updates, exposing the system to potential threats. Operational issues may arise, and compatibility with newer technologies becomes a concern. To mitigate these risks, continuous upgrades are strongly recommended to ensure the website remains secure, functional, and aligned with industry standards.

Sitefinity offers a straightforward upgrade path allowing users to seamlessly transition from older versions to the most recent release.
