A general description is here.
The default for ‘tools::write_PACKAGES(rds_compress=)’ has been changed
to ‘"xz"’ to match the compression used by CRAN.
‘write.table()’ and related functions, ‘writeLines()’, and perhaps other functions writing text to connections did not signal errors when the writes failed, e.g. due to a disk being full. Errors will now be signalled if detected during the write, warnings if detected when the connection is closed. (PR#17243)
