 CHANGES:
 
+* token: Token creation with custom token ID via `id` will no longer allow periods (`.`) as part of the input string. 
+  The final generated token value may contain periods, such as the `s.` prefix for service token 
+  indication. [[GH-8646](https://github.com/hashicorp/vault/pull/8646/files)]
 * token: Token renewals will now return token policies within the `token_policies` , identity policies within `identity_policies`, and the full policy set within `policies`. [[GH-8535](https://github.com/hashicorp/vault/pull/8535)]
 * kv: Return the value of delete_version_after when reading kv/config, even if it is set to the default. [[GH-42](https://github.com/hashicorp/vault-plugin-secrets-kv/pull/42)]
