+* **Enhanced EAL ``-l`` corelist argument.**
+
+  Added support to the EAL ``-l`` argument for the full range of core-to-cpu mapping options supported by the ``--lcores`` EAL argument.
+  Previously, ``-l`` only supported a subset of the options,
+  allowing only a list of cpus to be specified, which would be mapped 1:1 with internal lcore ids.
+  Now, it is possible to use the shortened ``-l`` form to map lcore ids to threads running on specific CPUs.
+  See the :doc:`../linux_gsg/eal_args.include` guide for examples.

 * **Added PMU library.**
