+# Changelog
+
+All notable changes to this project will be documented in this file.

+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## Guideline to update the version
+
+Increment the:
+
+* MAJOR version when you make incompatible API/ABI changes,
+* MINOR version when you add functionality in a backwards compatible manner, and
+* PATCH version when you make backwards compatible bug fixes.

+Notes:
+
+While opentelemetry-cpp Logs are still in experimental stage,
+[#1383](https://github.com/open-telemetry/opentelemetry-cpp/pull/1383) updated
+opentelemetry-proto to 0.17.0, which includes some breaking change in the
+protocol, like
+[this](https://github.com/open-telemetry/opentelemetry-proto/pull/373). This
+makes `name` parameter for our log API unnecessary. However, this parameter is
+marked deprecated instead of being removed in this release, and it will be
+removed in future release.
