Hi,

I'm fiddling with SystemChangeAnnouncer [1] and noticed that
#traitDefinitionChangedFrom:to:
is not sent anymore. In a 3.9 image it has 2 senders: ClassTrait >>
uses: and Trait class >> named:uses:category:env:

What should we do? Drop this kind of change? Put back the notifications?

[1] You can load it with:

Installer ss
	project: 'AXAnnouncements';
	install: 'Announcements';
	project: 'SysChangeAnnouncer';
	install: 'SystemChangeAnnouncer';
	install: 'SystemChangeAnnouncerCompatibility'

There are some test checking compatibility of the old and new implementation in:
