ABI Changes
-----------
-.. This section should contain ABI changes. Sample format:
-
- * sample: Add a short 1-2 sentence description of the ABI change
- which was announced in the previous releases and made in this release.
- Start with a scope label like "ethdev:".
- Use fixed width quotes for ``function_names`` or ``struct_names``.
- Use the past tense.
+* No change, kept ABI v20. DPDK 20.02 is compatible with DPDK 19.11.
- This section is a comment. Do not overwrite or remove it.
- Also, make sure to start the actual text at the margin.
- =========================================================
+* The soname for each stable ABI version should be just the ABI version major
+ number without the minor number. Unfortunately both major and minor were used
+ in the v19.11 release, causing version v20.x releases to be incompatible with
+ ABI v20.0.
-* No change, kept ABI v20. DPDK 20.02 is compatible with DPDK 19.11.
+ The `commit f26c2b39b271 <https://git.dpdk.org/dpdk/commit/?id=f26c2b39b271>`_
+ fixed the issue by switching from 2-part to 3-part ABI version numbers so that
+ we can keep v20.0 as soname and using the final digits to identify the DPDK
+ 20.x releases which are ABI compatible.
