.The `createrepo_c` utility now skips packages whose metadata contains the disallowed control characters To ensure a valid XML, the package metadata must not contain any control characters, with the exception of: * the horizontal tab * the newline character * the carriage return character With this update, the `createrepo_c` utility does not include packages with metadata containing disallowed control characters in a newly created repository, and returns the following error message: ---- C_CREATEREPOLIB: Critical: Cannot dump XML for PACKAGE_NAME (PACKAGE_SUM): Forbidden control chars found (ASCII values <32 except 9, 10 and 13) ----
