| - The [`lock()`](/en-US/docs/Web/API/ScreenOrientation/lock) and [`unlock()`](/en-US/docs/Web/API/ScreenOrientation/unlock) methods of the {{domxref("ScreenOrientation")}} interface are now supported for Android and for Windows tablets. ([Firefox bug 1983483](https://bugzil.la/1983483)) | ||

||
| - The [View Transition API](/en-US/docs/Web/API/View_Transition_API) is now supported for [SPAs (single-page applications)](/en-US/docs/Glossary/SPA). This provides a mechanism for easily creating animated transitions between different website views. ([Firefox bug 1985809](https://bugzil.la/1985809)). | ||
| - The {{domxref("CSSStyleProperties")}} interface of the [CSS Object Model (CSSOM)](/en-US/docs/Web/API/CSS_Object_Model) is now implemented (this was renamed from a non-standard interface `CSS2Properties`). The new interface is present but not yet used. ([Firefox bug 1919582](https://bugzil.la/1919582)). |

FWIW wasn't sure what to say about this, given you can't yet use it for anything. The docs are going in in a separate PR that is updated for the 145 story. BCD is also going to reflect 145.

Prevously I have added a note that explains: This is parsed but does nothing e.g. http://localhost:5042/en-US/docs/Mozilla/Firefox/Experimental_features#text-autospace_property
