`read-hash-extend' is still there. This just removed the #'
read-hash-extension, which was the identity extension: #'foo == foo.

`read-hash-extend' overrides any core hash forms, so this extension
prevented #'foo == (syntax foo). It would be easy for an affected reader
to add this particular extension back, though.

They are all described by the commit log, right? It is true that some of
the changes are not related to others, though. I'll try to separate them
out more in the future.

OK.

Yes, and to the cond-expand forms. I have a lot of things I need to add
to NEWS before the release.

Cheers,
