+title: Remove `sp_runtime::RuntimeString` and replace with `Cow<'static, str>` or
+  `String` depending on use case
+doc:
+  - audience: Runtime Dev
+    description: |
+      Deprecate `RuntimeString`, replace with `String` or `Cow<'static, str>` where appropriate.
+
+      For downstream projects the upgrade will primarily consist of following two changes:
+      ```diff
+      #[sp_version::runtime_version]
+      pub const VERSION: RuntimeVersion = RuntimeVersion {
+      -	spec_name: create_runtime_str!("statemine"),
+      -	impl_name: create_runtime_str!("statemine"),
+      +	spec_name: alloc::borrow::Cow::Borrowed("statemine"),
+      +	impl_name: alloc::borrow::Cow::Borrowed("statemine"),
+      ```
+      ```diff
+      		fn dispatch_benchmark(
+      			config: frame_benchmarking::BenchmarkConfig
+      -		) -> Result<Vec<frame_benchmarking::BenchmarkBatch>, sp_runtime::RuntimeString> {
+      +		) -> Result<Vec<frame_benchmarking::BenchmarkBatch>, alloc::string::String> {
+      ```
+      SCALE encoding/decoding remains the same as before, but serde encoding in runtime has changed from bytes to string (it was like this in `std` environment already).
