This time, apart of using 'gbp dch', I mangle the changelog by hand a lot.

+iptables (1.6.0-3) unstable; urgency=medium
+
+  * several changes in this release. To put it short: split packages into
+    libiptc, libip4tc, lipip6tc and libxtables-dev, so we no longer require
+    the old iptables-dev binary package.
+    .
+    Also, give to all binary packages Multi-Arch support.
+    .
+    Another important thing: move libs from /lib to /usr/lib
+    .
+    Now follows almost all the commits I've made:
+    .

+    #812973)

+  * [4486e87] iptables,iptables-nftables-compat: Suggests kmod (Closes:
+    #623865)

+    #793299)
+  * [4b6ae2e] manpages: add xtables-compat.8
