+Subject: [PATCH] Downstream-only: add an SONAME version
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Upstream was asked about .so versioning and setting SONAME properly and
+seemed unprepared to handle the request:
+https://github.com/PixarAnimationStudios/USD/issues/1259#issuecomment-657120216
+
+A patch was offered:
+https://github.com/PixarAnimationStudios/USD/issues/1387
+but it was not sufficient for the general case, since (1) it only handled the
+monolithic build, and (2) it derived the .so version from PXR_MAJOR_VERSION,
+which is *not* reliably bumped on API or ABI changes, and currently is still
+zero.
+
+We will therefore probably need to keep doing downstream .so versioning for
+the foreseeable future. Currently we are assuming that the ABI is likely to
+change on every release (an appropriate assumption for a large C++ project
+with no ABI stability policy), so we build the .so version from the project
+version. Note that the “hidden” major version is zero, so this complies with
+the “0.” prefix recommended in the packaging guidelines.
+
+https://docs.fedoraproject.org/en-US/packaging-guidelines/#_downstream_so_name_versioning
+
+A known defect of this patch is that it causes the hdTiny.so example plugin
+to be versioned as well, which is undesired. This is not a serious problem
+because we do not want to package the built plugin anyway. (It should not be
+built with -DPXR_BUILD_EXAMPLES=OFF, but it is.)
