Update to the latest version of the Cedar packages:
package name
version
@rei/cedar
^10.x.x
@rei/febs
^8.3.x
Remove @babel/preset-env and @babel/register if they are included in your project, the functionality provided by these modules is now included in the latest version of FEBS.
Depending on the age of your microsite, you may wish to ensure your other dependencies are also up to date. As always, Climbers Site(opens new window) is a good reference point.
If your project depends on any shared component packages (i.e, FEDPACK, FEDCOMP, FEDPAGES), you will want to update those packages to the new version of Cedar before updating your microsite.
The removal of polyfills involves some risk of breaking changes. If for some reason you need to support older browsers, you should ensure this update does not break critical functionality prior to incorporating.
