What's Changed

Deprecated instantiating components through Component.init

You should have probably been doing .create.

• deprecate Component init by @adhami3310 in #4904

Overwrite rx.serializer

You can overwrite a serializer in reflex through @rx.serializer (previously we were erroring here), for example:

@serializer(to=str, overwrite=True) # overwrite flag here suppresses warning about overriding a builtin serializer as an intentional decision
def serialize_uuid(uuid: UUID) -> str:
    return "UUID" + str(uuid)

• serialize uuid and allow overwriting serializers by @adhami3310 in #4888

Use .f with Vars

You can now use the .f in f-strings with state Vars, for example:

class State(rx.State):
  value_of_pi: float = 3.14159265359

rx.text(f"{State.value_of_pi:.2f}")

Note that we now error when you provide a formatter that we don't support. PRs are welcome in extending the functionality beyond :.Xf.

• add support for .f format by @adhami3310 in #4855
