Umbraco 15 was released in November 2024. With this, a lot of changes have taken place, including a new rich text editor, client credentials, optimised caching, enhanced multilingual management and more. In this blog we go into detail of all the new updates and what they mean to your digital platform.
Because of a change with licensing, Umbraco 15 comes with the introduction of the Tiptap Rich Text Editor, a change from the previous TinyMCE Rich Text Editor. Built on an open-source framework, Tiptap offers all the essential features editors expect, along with extensive customisation options. Its intuitive design ensures a smooth editing experience, making it easy for users transitioning from editors like TinyMCE.
Umbraco 15 makes it easier for different systems to communicate with each other by introducing a new feature called Client Credentials. This means that instead of having to manually enter passwords every time systems need to connect, they can now authenticate automatically and securely, making it faster and safer to connect with external tools and automate tasks. This feature is part of Umbraco's Management API, designed to save time and simplify complex processes.
Optimised Caching with HybridCache
Umbraco 15 brings a fresh caching system designed to enhance performance. Featuring a lazy-loading approach and robust compatibility with distributed setups, it offers lower memory usage, quicker startup and seamless load balancing across multiple servers. It’s ideal for high-traffic and content-rich websites. The new Microsoft HybridCache delivers faster content delivery and an improved user experience.
You'll notice significantly better performance when managing large amounts of content on your website, thanks to smarter memory management that prevents slowdowns, even under heavy resource demands.
A key improvement in Umbraco’s caching approach is the move from an eager content cache, where all content is stored in memory at once, to a more efficient lazy-loaded system. With this update, your essential content (determined by the new cache seeding feature) is preloaded during startup, ensuring your most important pages are always ready to go. Additional content is loaded only when needed, reducing memory usage and keeping your site fast and responsive, no matter how much content you have!
Umbraco 15 is powered by the cutting-edge .NET 9 (ASP.NET Core 9) framework, offering the latest in performance, security and scalability. With .NET 9, your website is built on a modern, high-speed foundation that’s designed to handle growing demands with ease. This framework provides developers with advanced tools to create fast, secure and responsive applications while keeping resource usage low.
Umbraco 15 allows you to effortlessly handle multilingual websites with Block Level Variations. This allows you to manage and customise specific pieces of content, or "blocks," for different languages or regions without changing the overall structure of your website. Instead of duplicating entire pages for multilingual setups, you can vary individual blocks within a page. For example, you can keep a consistent design and layout but localise text, images or other content within specific blocks to suit the needs of different audiences. This approach ensures consistency while making localisation more efficient and flexible.
With more enterprises turning to Umbraco for managing content-rich, large-scale websites, Umbraco 15 is built to meet the challenge. Featuring improved caching, advanced load-balancing and robust multi-server support, it’s designed to deliver exceptional performance for even the most complex digital experiences. Whether it’s e-commerce or media-heavy platforms, this CMS is equipped to handle your most demanding projects effortlessly.
Umbraco 15 has been built to be more accommodating to large and content-heavy websites by introducing new features such as multilingual management, advanced caching setups and enhanced API integrations. It’s worth noting that Umbraco 15 follows a short-term support model, making it ideal for those who prefer to stay up-to-date with the latest features and updates, while long-term support options remain available in other releases.
