5.19.3

(fix): Revert the smart-casing digit/word boundary behavior introduced in 5.18.4. snake_case names keep a digit run fused to the following word (conversations_v2configuration), restoring pre-5.18.4 output. The behavior will become opt-in via the new smart-casing-digit-word-boundary option in generators.yml once the generator consumes the IR version that carries the setting.

5.19.2

(fix): Fix the OAuth token provider crashing with “Access token not present in OAuth response” when the token response does not include a refresh token. Client-credentials token responses often omit refresh_token; the provider now treats it as optional instead of raising.

5.19.1

(fix): OAuth client credentials token requests now send grant_type: "client_credentials" when the token endpoint declares a non-literal grant_type request property. The property is synthesized in the token request and is no longer surfaced as a user-supplied option.
