+Dynamic library versions
+------------------------
+
+The library follows `semantic versioning <https://semver.org>`_, so some dynamic library files and links have major and minor binary versions in their names.
+
+ - The minor version is incremented if new functionality is introduced to the public API and backwards compatibility is preserved.
+ - The major version is incremented and the minor version is set to 0 if any backwards incompatible changes are introduced.
+
+It is not recommended to use dynamic library files without any versioning in production.
+
+Environment scripts set binary versions in ``DAL_MAJOR_BINARY`` and ``DAL_MINOR_BINARY`` variables on call.
