latin-1 / ISO-8859-1 aliases),

Final and preliminary releases of the same file

datasus_download() fail with “Duplicate destfiles” or
served a stale preliminary file forever. Existing caches will
re-download once..part name and

datasus_download() gains success and
error columns and downloaded reflects the real
outcome. datasus_fetch() skips failed files with a warning
and errors if every download failed.datasus_fetch() prefers final over preliminary
data: when the same file (matched case-insensitively, and
treating SINAN_P / ESUSNOTIFICA_P as
preliminary aliases of SINAN / ESUSNOTIFICA)
is available in both trees only the final copy is read, so rows are not
duplicated. A final candidate that could not be confirmed on the FTP
does not suppress a preliminary copy known to exist.
datasus_fetch() also gains refresh and
overwrite arguments (the vignette documented
refresh but it was not accepted).timeout no longer caps the whole
transfer. It used to be passed to libcurl as the total time
allowed per file (240 s), which aborted large files on the slow DATASUS
FTP. It now defaults to Inf; stalled transfers are detected
with a connect timeout and a low-speed limit instead.exists = NA, instead of being silently reported
as absent.datasus_build_path() no longer recycles a vector
year against the SINASC path templates (which produced a
warning and wrong paths).SINAN_P was advertised in
datasus_sources() but had no file types and could never be
fetched; its file types are now registered.year, month and uf are
validated before any network access.datasus_download(use_cache = FALSE) without
