+	blacklistd has been renamed to blocklistd, following upstream.
+	The library is now libblocklist(3) with blocklist_*() functions,
+	the daemon and control program are blocklistd(8) and
+	blocklistctl(8), the configuration file is /etc/blocklistd.conf,
+	the rc.conf knobs are blocklistd_enable and blocklistd_flags, and
+	the sshd_config option is UseBlocklist.  The build options are
+	WITH[OUT]_BLOCKLIST and WITH[OUT]_BLOCKLIST_SUPPORT.
+
+	The old names keep working for now: libblacklist, blacklistd,
+	blacklistctl, /etc/blacklistd.conf, the blacklistd rc script and
+	the old build options are all still provided, but they warn on
+	use and will be removed in a future release.  Move your
+	configuration to the new names.  Note that the last column of the
+	configuration file, formerly "disable", is now "duration".

+
+Vendor branch: vendor/blocklist, tagged vendor/blocklist/YYYYMMDD after
+the upstream commit date.  Upstream has no releases; import HEAD.
+
+To import a new snapshot:
+
+  1) git clone https://github.com/zoulasc/blocklist.git and note the
+     commit hash and date.
+  2) In this repository:
+	git fetch <clone> HEAD
+	c=$(git commit-tree FETCH_HEAD^{tree} -p vendor/blocklist \
+	    -m "Import blocklist YYYY-MM-DD (shorthash)")
+	git branch -f vendor/blocklist $c
+	git tag vendor/blocklist/YYYYMMDD $c
+  3) On master:
+	git merge -X subtree=contrib/blocklist vendor/blocklist
+  4) Re-run sh midnightbsd-changes.sh in contrib/blocklist and check
+     that nothing else changed with
+	git diff vendor/blocklist HEAD:contrib/blocklist
+  5) If source files were added or removed, update lib/libblocklist,
+     usr.sbin/blocklistd and usr.sbin/blocklistctl.
+  6) Build world and test sshd(8) and fingerd(8) integration.
+
+Files that are not upstream:
+
+  bin/blacklistctl.c bin/blacklistd.c bin/old_internal.[ch]
+  include/blacklist.h include/old_bl.h lib/blacklist.c lib/old_bl.c
+  bin/blacklistctl.8 bin/blacklistd.8 bin/blacklistd.conf.5 lib/libblacklist.3
+	Compatibility sources for the old blacklist names, taken from
+	FreeBSD.  They build lib/libblacklist, usr.sbin/blacklistd and
+	usr.sbin/blacklistctl so existing configurations keep working
+	with a warning.
+  port/config.h
+	Wrapper that pulls in port/port.h; upstream generates this with
+	autoconf.
