+  description: |-
+    This changes `sc-client-db` to not always enable `jemalloc` by default for rocksdb. Instead it is now controlled by `jemalloc-allocator` feature. This is now also forwarded up to `polkadot` via `polkadot-cli` and `sc-service`. There we ultimately decide if `jemalloc` should be enabled or not.
