 # Site compatibility-impacting changes coming to Microsoft Edge
 
@@ -39,6 +39,7 @@ This table lists:
 | Deprecate unload event | Future release (TBD) | | Introduces a new Permission-Policy to allow creating unload event listeners. The default policy is `allow`, but the default policy will gradually be migrated to `deny`, such that unload handlers stop firing on pages, unless a page explicitly opts in to re-enable them.  This change is happening in the Chromium project, on which Microsoft Edge is based.  For more information, see [Intent to Deprecate: Deprecate unload event](https://groups.google.com/a/chromium.org/g/blink-dev/c/dvusqw9-IhI/m/SBkm_u1RAQAJ). |
 | Removal of cross-origin subframe JavaScript dialogs | Future release (TBD) | | Removes `window.alert`, `window.prompt`, and `window.confirm` from cross-origin iframes.  This change is happening in the Chromium project, on which Microsoft Edge is based.  For more information, see [Intent to Remove: Cross origin subframe JS Dialogs](https://groups.google.com/a/chromium.org/g/blink-dev/c/hTOXiBj3D6A/m/JtkdpDd1BAAJ). |
 | Deprecate `textprediction` attribute | v131 |  | Removes support for the `textprediction` HTML attribute, which is a nonstandard attribute that's used to enable or disable the browser-based Text Prediction feature for long-form text inputs.  Instead, use the standardized `writingsuggestions` attribute, which functions similarly to `textprediction`, but also applies to other writing-assistance features that browsers may provide.  Sites that explicitly set `textprediction` to `true` or `false` can instead set `writingsuggestions` to the same value.  For more information, see [Writing suggestions](https://html.spec.whatwg.org/multipage/interaction.html#writing-suggestions) in the HTML specification. |
+| Removal of Token Binding support | v127, v130 | | Token Binding uses cryptographic certificates on both ends of the TLS connection in an attempt to close the security gap of bearer tokens, which may be lost or stolen.  The enterprise policy [AllowTokenBindingsForUrls](/deployedge/microsoft-edge-policies#allowtokenbindingforurls) will no longer be supported, as of v127.  Support for the Token Binding protocol will be removed in v130. |
 | Removal of mutation events | v127 | | Removes support for mutation events in Chromium. Use the [MutationObserver](https://developer.mozilla.org/docs/Web/API/MutationObserver) API instead.  See [Intent to Deprecate: Mutation Events](https://groups.google.com/a/chromium.org/g/blink-dev/c/qDsKRU-cQ_4/m/isA1mZ_aAAAJ). |
 | Removal of Web SQL | v124 | | Fully removes Web SQL support. In prior releases, Web SQL support was disabled by default but could be re-enabled via the [WebSQLAccess policy](/deployedge/microsoft-edge-policies#websqlaccess). After this change, there is no longer any mechanism to enable Web SQL support. This change is happening in the Chromium project, on which Microsoft Edge is based. For more information, see [Intent to Deprecate and Remove Web SQL](https://groups.google.com/a/chromium.org/g/blink-dev/c/fWYb6evVA-w/m/pziWcvboAgAJ). |
 | Added support for AVIF and AV1 file formats | v121 | | Microsoft Edge now supports the AVIF and AV1 file formats, which offer better compression and higher quality images and videos.  Users can enjoy faster loading times and better quality media on websites. |
