## 1.22.1

**`(fix):`** Add 'v' prefix to sdkVersion in metadata.json to follow Go module versioning conventions.

## 1.22.0

**`(feat):`** Generate error\_codes.go per-namespace for multi-namespace Go SDKs. Each namespace now has its
own error\_codes.go file containing only the error codes and error types from that namespace,
rather than a single global file with all errors.
