– Added [`gpfup_file_error`](https://gravitywiz.com/documentation/gpfup_file_error) JavaScript action hook.
– Added [`gpfup_block_submission_on_error`](https://gravitywiz.com/documentation/gpfup_block_submission_on_error) JavaScript filter to prevent the form from being submitted while any file is in an errored state.
– Improved the error message shown when an upload is rejected by the server (e.g. by a firewall or security plugin) to include the HTTP status code instead of a generic “HTTP Error.”
