+### Bug Fixes
+
+* **deps:** Require google-api-core >=1.34.0, >=2.11.0  ([e5875cb](https://github.com/googleapis/python-bigtable/commit/e5875cbe8551329fbb64f273ca21d6b7ada641ec))
+* Drop usage of pkg_resources ([e5875cb](https://github.com/googleapis/python-bigtable/commit/e5875cbe8551329fbb64f273ca21d6b7ada641ec))
+* Fix timeout default values ([e5875cb](https://github.com/googleapis/python-bigtable/commit/e5875cbe8551329fbb64f273ca21d6b7ada641ec))
+
+
+### Documentation
+
+* **samples:** Snippetgen should call await on the operation coroutine before calling result ([e5875cb](https://github.com/googleapis/python-bigtable/commit/e5875cbe8551329fbb64f273ca21d6b7ada641ec))
