+Milestones definition
+---------------------
+
+Each DPDK release has milestones that help everyone to converge to the release date.
+The following is a list of these milestones together with
+concrete definitions and expectations for a typical release cycle.
+An average cycle lasts 3 months and have 4 release candidates in the last month.
+Test reports are expected to be received after each release candidate.
+The number and expectations of release candidates might vary slightly.
+The schedule is updated in the `roadmap <https://core.dpdk.org/roadmap/#dates>`_.
+
+.. note::
+   Sooner is always better. Deadlines are not ideal dates.
+
+   Integration is never guaranteed but everyone can help.
+
+Roadmap
+~~~~~~~
+
+* Announce new features in libraries, drivers, applications, and examples.
+* To be published before the previous release.
+
+Proposal Deadline
+~~~~~~~~~~~~~~~~~
+
+* Must send an RFC (Request For Comments) or a complete patch of new features.
+* Early RFC gives time for design review before complete implementation.
+* Should include at least the API changes in libraries and applications.
+* Library code should be quite complete at the deadline.
+* Nice to have: driver implementation, example code, and documentation.
+
+rc1
+~~~
+
+* Priority: libraries. No library feature should be accepted after -rc1.
+* API changes or additions must be implemented in libraries.
+* The API must include Doxygen documentation
+  and be part of the relevant .rst files (library-specific and release notes).
+* API should be used in a test application (``/app``).
+* At least one PMD should implement the API.
+  It may be a draft sent in a separate series.
+* The above should be sent to the mailing list at least 2 weeks before -rc1
+  to give time for review and maintainers approval.
+* If no review after 10 days, a reminder should be sent.
+* Nice to have: example code (``/examples``)
+
+rc2
+~~~
+
+* Priority: drivers. No driver feature should be accepted after -rc2.
+* A driver change must include documentation
+  in the relevant .rst files (driver-specific and release notes).
+* Driver changes should be sent to the mailing list before -rc1 is released.
+
+rc3
+~~~
+
+* Priority: applications. No application feature should be accepted after -rc3.
+* New functionality that does not depend on libraries update
+  can be integrated as part of -rc3.
+* The application change must include documentation in the relevant .rst files
+  (application-specific and release notes if significant).
+* Libraries and drivers cleanup are allowed.
+* Small driver reworks.
+
+rc4
+~~~
+
+* Documentation updates.
+* Critical bug fixes only.
