So let me dive into highlights and explain what the benefits are for you:
You can use the Telerik Spreadsheet UI component to deliver an Excel-like look and feel to your web apps. The UI is very intuitive because of its similarity to MS Excel and Google Sheets. The control also features built-in Excel XLSX import/export, keyboard navigation, editing, and much more.
If you would like to learn more, check out this blog post or give this live demo a spin. The official release is scheduled for Q1 2016 so that you have enough time to play with the Beta and share your feedback in the feedback portal, the dedicated forum or the support ticketing system.
With this release, you gain modern rendering (RenderMode="Lightweight") in about 99% of the controls. The latest controls that obtained simplified markup, semantic rendering and easy-to-customize skins in Q3’15 are: ColorPicker, ImageEditor, FileExplorer, PivotGrid, Splitter and SocialShare.
Our plans are to develop only the Lightweight rendering since it makes the controls more responsive, lightweight and easy to customize. All new controls, skins, features and support for new browsers will be developed only for the modern rendering.
At the same time we will not discontinue the stable Classic rendering for at least a year (until Q3 2016) and we will provide critical fixes for it.
Along with the modernization of the rendering, we continue to work on and improve the responsive behavior of the controls. The newly introduced elastic capabilities in the ColorPicker, FileExplorer, ProgressArea, SocialShare and TileList controls will help you build apps tailored to any device's screen size. Look at the Mobile Support and Responsiveness help article, if you are interested in learning more.
A common scenario is to customize and tweak the overall appearance of the controls to fit to your specific web site/app colors and requirements. Until Q3 2015 this was possible only for the Classic rendering of the controls through the Visual Style Builder. Now you can do so for the Lightweight rendering as well!
For example, if you want to create a new skin or to customize an existing one for the Lightweight rendering of the AJAX controls, you can rely on the new Theme Builder app.
For all Twitter Bootstrap fans, I want to share the good news that we are working on a new special feature (the third option in the Theme Builder) that will allow you to import Twitter Bootstrap themes, to read their color information, and to apply it to the Telerik Bootstrap skin. This will ensure that the Telerik AJAX controls will use a similar color scheme as your Bootstrap components when both reside on the same page.
Note that the Import Bootstrap Theme functionality is currently in Beta and has limited capabilities. We want to collect more input from you, our fellow developers, before bringing new functionality prior the official launch. That's why I kindly invite you to share all your requirements, scenarios and custom Twitter Bootstrap themes with us, by dropping us an e-mail at firstname.lastname@example.org, in the feedback portal, via a ticket or a forum post.
The new functionality introduced in Q3 is just the beginning of our major plan to improve the AJAX suite in 2016 to follow the latest trends in the industry regarding accessibility. Right now, you can take advantage of the following new features that will help you to develop better accessible web apps:
With the sole purpose of making your development easier, shortly after the release we are going to launch the new version of the popular Telerik Web Mail sample app. It offers a redesigned modern look influenced by the Outlook.com site and leverages the responsive capabilities of the Telerik AJAX controls. You can use it as a starting point to create your own mail client applications as well as to see the controls interoperability in action.
