# vroom 1.5.7 * Jenny Bryan is now the official maintainer. * Fix uninitialized bool detected by CRAN's UBSAN check (tidyverse/vroom#386) * Fix buffer overflow when trying to parse an integer field that is over 64 characters long (tidyverse/readr#1326) * Fix subset indexing when indexes span a file boundary multiple times (#383) # vroom 1.5.6 * `vroom(col_select=)` now works if `col_names = FALSE` as intended (#381) * `vroom(n_max=)` now correctly handles cases when reading from a connection and the file does _not_ end with a newline (tidyverse/readr#1321) * `vroom()` no longer issues a spurious warning when the parsing needs * to be restarted due to the presence of embedded newlines * (tidyverse/readr#1313) Fix performance * issue when materializing subsetted vectors (#378) * `vroom_format()` now uses the same internal multi-threaded code as `vroom_write()`, improving its performance in most cases (#377) * `vroom_fwf()` no longer omits the last line if it does _not_ end with a newline (tidyverse/readr#1293) * Empty files or files with only a header line and no data no longer cause a crash if read with multiple files (tidyverse/readr#1297) * Files with a header but no contents, or a empty file if `col_names = FALSE` no longer cause a hang when `progress = TRUE` (tidyverse/readr#1297) * Commented lines with comments at the end of lines no longer hang R (tidyverse/readr#1309) * Comment lines containing unpaired quotes are no longer treated as unterminated quotations (tidyverse/readr#1307) * Values with only a `Inf` or `NaN` prefix but additional data afterwards, like `Inform` or no longer inappropriately guessed as doubles (tidyverse/readr#1319) * Time types now support `%h` format to denote hour durations greater than 24, like readr (tidyverse/readr#1312) * Fix performance issue when materializing subsetted vectors (#378) # vroom 1.5.5 * `vroom()` now supports files with only carriage return newlines (`\r`). (#360, tidyverse/readr#1236) * `vroom()` now parses single digit datetimes more consistently as readr has done (tidyverse/readr#1276) * `vroom()` now parses `Inf` values as doubles (tidyverse/readr#1283) * `vroom()` now parses `NaN` values as doubles (tidyverse/readr#1277) * `VROOM_CONNECTION_SIZE` is now parsed as a double, which supports scientific notation (#364) * `vroom()` now works around specifying a `\n` as the delimiter (#365, tidyverse/dplyr#5977) * `vroom()` no longer crashes if given a `col_name` and `col_type` both less than the number of columns (tidyverse/readr#1271) * `vroom()` no longer hangs if given an empty value for `locale(grouping_mark=)` (tidyverse/readr#1241) * Fix performance regression when guessing with large numbers of rows (tidyverse/readr#1267)

Hi,
I'll post it here as well since the bug seems to be the same also in readr::melt_table2.
r-lib/meltr#10
Sorry if this was unneeded
