-* X behavior was changed ([#X](https://github.com/apache/beam/issues/X)).
+* (Python) Removed `google-perftools` from the SDK container images. Users who wish to use `--profiler_agent=tcmalloc` should install google-perftools APT package in their custom container images separately ([#39323](https://github.com/apache/beam/issues/39323)).
