 ## Known Limitations and Incompatibilities
 
 This library tries to minimize the amount of "special handling" that a cross-browser extension has to do to be able to run on the supported browsers from a single codebase, but there are still cases when polyfillling the missing or incompatible behaviors or features is not possible or out of the scope of this polyfill.

 ### MSEdge support
 
-[With the Microsoft announcement related to the MSEdge future](https://github.com/MicrosoftEdge/MSEdge/blob/master/README.md) there aren't many compelling reasons to officially include in this polyfill any workarounds specific to the current MSEdge versions (and then maintaining them over the time), and so MSEdge is currently **unsupported**.
+MSEdge versions >= 79.0.309 are unofficially supported as a Chrome-compatible target (as for Opera or other Chrome-based browsers that also support extensions).
 
-Once the first Chrome-based MSEdge version is going to be released, we will be able to verify if any actual changes to this polyfill are needed to officially support the Chrome-based MSEdge versions.
+MSEdge versions older than 79.0.309 are **unsupported**, for extension developers that still have to work on extensions for older MSEdge versions, the MSEdge `--ms-preload` manifest key and the [Microsoft Edge Extension Toolkit](https://docs.microsoft.com/en-us/microsoft-edge/extensions/guides/porting-chrome-extensions)'s Chrome API bridge can be used to be able to load the webextension-polyfill without any MSEdge specific changes.

-In the meantime, for extension developers that still have to work on MSEdge extensions before it is switched to the next Chromium-based version, the MSEdge `--ms-preload` manifest key and the [Microsoft Edge Extension Toolkit](https://docs.microsoft.com/en-us/microsoft-edge/extensions/guides/porting-chrome-extensions)'s Chrome API bridge can be used to be able to load the webextension-polyfill without any MSEdge specific changes.
