The N&N page for 4.5.0.Final currently only has this:

Freemarker component deprecation
The Freemarker component has been marked deprecated as there is no more maintenance on the source code. It is still available in Red Hat Central and may be removed in the future.
Related JIRA: JBIDE-24484

Question 1:
This was only deprecation? This feature was already in central and not included in the coretools feature? Just checking.
Looks like this was the case - I found this:
https://github.com/jbosstools/jbosstools-freemarker/pull/79/files

Question 2:
Shouldn't we include a N&N note on deprecation / move of Seam 3 stuff? I think we should.
More details on those changes here:
JBDS-4495
JBIDE-24379
TL;DR: These features are both deprecated and moved to central:
org.jboss.tools.cdi.seam.feature
org.jboss.tools.runtime.seam.detector.feature

We're a bit confused about the seam (2) runtime detector, we thought that was already gone. We can ignore that. What we probably want to say is that Seam 3 feature / tooling has been deprecated and moved to Central.
