It looks like gnus-newsgroup-name (and friends?) are no longer set when
the summary mode hooks are run, so hooks that rely on that are now
broken.
It also looks like summary mode line highlights no longer works.

Yes, since `gnus-summary-mode' is now a real mode, it clears local
variables before running the hook. The right place for that sort of hook
is now `gnus-summary-prepared-hook'. I tried to change all the relevant
hooks I could within the codebase, but I guess gnus-mdrtn.el isn't
publicly available? I can change the Moderation section of the manual to
update the installation instructions.

I'll take a look now.

Hang on, I'm not sure what you mean here. You don't mean the
read/unread/ticked/etc face properties on individual articles lines in
the Summary buffer, do you? I'm not sure what highlighting happens in
the Summary mode line.

No, you can't break third-party software that way. You have to set the
variables the hooks expect to exist before calling the hook.
>> It also looks like summary mode line highlights no longer works.
I think that was a false alarm.

Okay. This patch should restore that behavior. I don't see any other
buffer-local variables that were being set to a specific value, other
than `gnus-newsgroup-name'.

I think that looks OK, but I don't understand the:
- (setq gnus-newsgroup-name group)
+; (setq gnus-newsgroup-name group)

That was just sort of a note to self -- if `gnus-newsgroup-name' is set
in `gnus-summary-mode' then it doesn't need to be set again in
`gnus-summary-setup-buffer'. But I was nervous I would break more stuff,
and couldn't bring myself to actually delete it.

You haven't pushed the fixes yet? Gnus is unusable for me on master as
it is.

Done. If that solves the problem completely I'll close the bug report.
