Release Notes

More accurate progress tracking

When compiling a large app, we weren't incrementing the counter for some time-consuming tasks. Like collecting imports and stateful-izing components. Now we do, so the progress bar is a more accurate estimate of how much progress has been made.

• add progrss for imports and statefulizing by @adhami3310 in add progrss for imports and statefulizing #5646

Remove autofocus (not auto_focus)

autofocus is an old guy we had and it wasn't working. Now we only have the HTML/React field auto_focus.

• remove autofocus by @adhami3310 in remove autofocus #5644

Make Tag immutable

If you happened to have overwrote _render or such, you might be familiar with Tag. We modified it to be immutable as we have been the victims of misusing its mutability. Review your code that involves _render or render.
