We are excited to announce SharePoint Framework version 1.12.1 with new capabilities focusing on Microsoft Teams and SharePoint topics. As part of this release, we adopted new preview model, which we will be using also with all the future release to increase the quality of the versions. This means that we will be shipping a public preview release for public review before the actual general availability of the version.

As custom SharePoint Framework components are being used by tens of millions of people each month in Microsoft Teams and in the SharePoint, it’s important that we minimize possibility of regressions with the new releases and we are committed on providing higher quality releases in future. We will be also focusing on the code craftmanship also in the other areas, like with updated focus on addressing known issues in the platform and not just focusing on the new features. Please keep the feedback coming on known issues which are causing you challenges. Our engineering team is committed on addressing these as part of the future development iterations.

Here are the key capabilities included in the SharePoint Framework 1.12.1:

• The Sync to Teams button in the Tenant App Catalog will use the Teams app manifest defined in the solution if present to create and publish a Teams app package to Microsoft Teams. If an app manifest file is not present, SharePoint will dynamically generate one.
• New web part APIs for detecting web part size and size changes
• Support on building Microsoft Teams meeting apps with the SharePoint Framework
• Add support for Node.js v14 and Gulp 4
