We are happy to announce the release of DotVVM 4.2 which brings many important improvements, and prepares the ground for DotVVM 5.0 which we’ve already started working on.

We’ve just published a new public preview of DotVVM 4.2 with a version tag 4.2.0-preview07-final. This version is available for all packages: open-source DotVVM framework, DotVVM Contrib controls, Bootstrap for DotVVM, and DotVVM Business Pack. All these packages are compatible with each other and have been tested together.

You may already be aware that DotVVM 4.0 has introduced a new feature called Composite Controls, which provides a new way to write controls in DotVVM. This approach eliminates the need to declare DotVVM properties in code-only controls, for which you had to use the dotprop code snippet and work with long property declaration blocks. Instead, it only requires declaring a `GetContents` method and placing individual control properties as arguments of the method. By using this approach, the control code appears much more attractive and readable.

After 8 months, we are thrilled to announce the release of DotVVM 4.1. The release contains the new DotVVM Auto UI library, numerous improvements and bug fixes, and a bunch of improvements of Composite controls which allowed us to create a brand new implementation of Bootstrap for DotVVM for Bootstrap 5.

Today, we have released the version 2.4 of the DotVVM framework, Bootstrap for DotVVM and DotVVM Business Pack.

It has been a few months since we released the preview of Bootstrap 4 for DotVVM, a popular library that simplifies the syntax of Bootstrap widgets, brings data-binding support, and integrates with the rest of DotVVM platform.

Few days ago, we have published a stable release of DotVVM 2.1 on the official NuGet feed. It is mostly performance & bug fix release, but a few new features made into this version as well.

So, you have upgraded to the new Bootstrap 4 for DotVVM and now Visual Studio is spitting errors all over the place?

The long-awaited version 4.0 of Bootstrap – the most popular CSS framework – has shipped at the beginning of this year, with some new widgets and features. A lot of changes were also made under the hood. Migration to flexbox and improved grid system now allows easy positioning and alignment. New colors should simplify to customize the appearance of Bootstrap applications.
