When I start my application (brand new 14.1.4) I get following npm warning: npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.
Hi Sascha. No need to worry as this is not a security issue, the library version is not just maintained anymore. Also this dependency is only used during the frontend build and not exposed for a running application in production mode.
