Announcing Stencil v4.0.0

Stencil Team

The Stencil team has been hard at work, and we’re excited to announce that Stencil v4.0.0 is now available! 

We have lots of exciting new features planned for later this year, so to set Stencil up for those, this release contains a few breaking changes.  Let’s take a look!

Removed In-Browser Compilation Support

Stencil had a little-known feature that allowed projects to compile their components directly in the browser. While this functionality was impressive, it was rarely used and was a significant burden for the team to maintain. Following a successful RFC period where we sought feedback from the community, we have decided to remove this functionality. 

Removed Support for Deprecated Browsers

In Stencil v3, we announced that support for legacy browsers was being deprecated. Starting with Stencil v4, Internet Explorer, pre-Chromium Edge, and Safari 10 are no longer supported.

Drop Node 14 Support

Node v14 hit end of life status in April of 2023. Support for this version of the Node runtime has been removed.

As you upgrade to Stencil v4.0, you can reach out to our team with any questions or issues. You can view the full changelog here
