 ## Versioning
 
+### Historical Versioning (Up to `v5.44.0`)
+
 Up to the release `v5.44.0`, **Astar** releases contained both the client & the runtime blobs.
 In general, each release contained both, with some specific releases (related to fixes) which only released e.g. client or runtime.
 Standard semantic versioning approach was used.
 
-The new approach will see the split of client & runtime releases.
+### New Versioning Approach (From `v5.45.0`)
+
+Starting with v5.45.0, the release process has been split into separate client and runtime releases, each following distinct versioning schemes:
 
 The **client release** will continue to follow semantic versioning, continuing where the former approach left off.
 E.g. the next expected minor release will be `v5.45.0`.

 * The `XX` part will be a number of 2 or more digits, starting with **10**, and will be incremented by **1** each time a new runtime release is made. E.g. `runtime-1000` will be followed by `runtime-1100`, which will be followed by `runtime-1200`, and so on. This is like a combination of _major_ and _minor_ semver versions.
 * The `YY` part will always be a 2 digit number, and serves as a _patch_ semver version. E.g. if we have `runtime-1000` and need to release a fix, the new release version will be `runtime-1001`.
 
+The runtime crate version will align its major and minor versions with the Rust crate version, while the patch version will always remain `00`. For example, a runtime release for `runtime-1100` corresponds to the Rust runtime crate version `11.0.0`. A minor runtime release such as `runtime-1101` corresponds to the Rust runtime crate version `11.1.0`.
