+- Update to 1.12.3:
+  - reworks and reshuffles the Automake testsuite a bit; fixing some
+    weaknesses and spurious failures in the process, but also, likely,
+    introducing new ones;
+
+  - introduces initial support for automatic dependency tracking with
+    the Portland Group C/C++ compilers (thanks to Dave Goodell and
+    Jeff A. Daily);
+
+  - fixes several long-standing bugs and limitations in the 'ylwrap'
+    script (thanks to Akim Demaille); among the other things, the
+    long-standing PR/491 and automake bug#7648 are now fixed.
