Hey @vsammy!
Unfortunately, I don't have any updates for you here.
Are there particular parts of your apps that you're looking to have support Arabic/Hebrew language? Or are you looking specifically for complete support?
At the moment the only solution I know of is to use custom CSS and individually target components by setting direction: rtl in their styling. Aside from this being considerable work if you have many different types of components, CSS classes aren't guaranteed between versions so it would require additional upkeep on your part.
