It is now possible (again?) to read from a list of connections (@bairdj, #514).
Internal change for compatibility with cpp11 >= 0.4.6 (@DavisVaughan, #512).
str() now works in a colorized context in the
presence of a column of class integer64, i.e. parsed with
col_big_integer() (@bart1, #477).
The embedded implementation of the Grisu algorithm for printing
floating point numbers now uses snprintf() instead of
sprintf() and likewise for vroom’s own code (@jeroen, #480).
vroom(col_select=) now handles column selection by
numeric position when id column is provided
(#455).
vroom(id = "path", col_select = a:c) is treated like
vroom(id = "path", col_select = c(path, a:c)). If an
id column is provided, it is automatically included in the
output (#416).
vroom_write(append = TRUE) does not modify an
existing file when appending an empty data frame. In particular, it does
not overwrite (delete) the existing contents of that file
(https://github.com/tidyverse/readr/issues/1408, #451).
vroom::problems() now defaults to
.Last.value for its primary input, similar to how
readr::problems() works (#443).
The warning that indicates the existence of parsing problems has been improved, which should make it easier for the user to follow-up (https://github.com/tidyverse/readr/issues/1322).
vroom() reads more reliably from filepaths
containing non-ascii characters, in a non-UTF-8 locale (#394,
#438).
vroom_format() and vroom_write() only
quote values that contain a delimiter, quote, or newline. Specifically
values that are equal to the na string (or that start with
it) are no longer quoted (#426).
Fixed segfault when reading in multiple files and the first file has only a header row of column names, but subsequent files have at least one row (#430).
Fixed segfault when vroom_format() is given an empty
data frame (#425)
Fixed a segfault that could occur when the final field of the final line is missing and the file also does not end in a newline (#429).
Fixed recursive garbage collection error that could occur during
vroom_write() when output_column() generates
an ALTREP vector (#389).
vroom_progress() uses
rlang::is_interactive() instead of
base::interactive().
col_factor(levels = NULL) honors the na
strings of vroom() and its own include_na
argument, as described in the docs, and now reproduces the behaviour of
readr’s first edition parser (#396).
Jenny Bryan is now the official maintainer.
Fix uninitialized bool detected by CRAN’s UBSAN check (https://github.com/tidyverse/vroom/pull/386)

parsing needs to be restarted due to the presence of embedded newlines
(https://github.com/tidyverse/readr/issues/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
(https://github.com/tidyverse/readr/issues/1293)
Empty files or files with only a header line and no data no longer cause a crash if read with multiple files (https://github.com/tidyverse/readr/issues/1297)
Files with a header but no contents, or a empty file if
col_names = FALSE no longer cause a hang when
progress = TRUE
(https://github.com/tidyverse/readr/issues/1297)
Commented lines with comments at the end of lines no longer hang R (https://github.com/tidyverse/readr/issues/1309)
Comment lines containing unpaired quotes are no longer treated as unterminated quotations (https://github.com/tidyverse/readr/issues/1307)
Values with only a Inf or NaN prefix
but additional data afterwards, like Inform or no longer
inappropriately guessed as doubles
(https://github.com/tidyverse/readr/issues/1319)
Time types now support %h format to denote hour
durations greater than 24, like readr
(https://github.com/tidyverse/readr/issues/1312)
Fix performance issue when materializing subsetted vectors (#378)
vroom() now supports files with only carriage return
newlines (\r). (#360,
https://github.com/tidyverse/readr/issues/1236)
vroom() now parses single digit datetimes more
consistently as readr has done

\n as the delimiter (#365,
https://github.com/tidyverse/dplyr/issues/5977)

col_name and col_type both less than the
number of columns
(https://github.com/tidyverse/readr/issues/1271)
vroom() no longer hangs if given an empty value for
locale(grouping_mark=)

those accepted by utils::read.table. e.g. vroom::vroom(col_types =
list(a = “integer”, b = “double”, c = “skip”))
vroom() now respects the quote
parameter properly in the first two lines of the file

quotes as well as without (#354). Previously vroom explicitly retained
field content inside quotes regardless of the value of
trim_ws.

types that are less than the number of columns (#296)
vroom() now outputs the correct column names even in
the presence of skipped columns (#293, tidyverse/readr#1215)
vroom_fwf(n_max=) now works as intended when the
input is a connection.
vroom() and vroom_write() now
automatically detect the compression format regardless of the file
extension for bzip2, xzip, gzip and zip files (#348)
vroom() and vroom_write() now
automatically support many more archive formats thanks to the archive
package. These include new support for writing zip files, reading and
writing 7zip, tar and ISO files.
vroom(num_threads = 1) will now not spawn any
threads. This can be used on as a workaround on systems without full
thread support.
Threads are now automatically disabled on non-macOS systems compiling against clang’s libc++. Most systems non-macOS systems use the more common gcc libstdc++, so this should not effect most users.
Parsers now treat NA values as NA even if they are valid values for the types (#342)
Element-wise indexing into lazy (ALTREP) vectors now has much less overhead (#344)
New vroom(show_col_types=) argument to more simply
control when column types are shown.

UTF-16 and UTF-32 by converting these files to UTF-8 under the hood
(#138)

lines within data, not just at the start of the file (#294,

vroom_parse_issue if there are non-fatal parsing
issues.
vroom() now emits a warning of class
vroom_mismatched_column_name if the user supplies a column
type that does not match the name of a read column (#317).

`vroom() correctly reads double values with comma as decimal separator (@kent37 #313)

quote if the format doesn’t use quoting
(https://github.com/tidyverse/readr/issues/991#issuecomment-616378446)

files with mixed windows and POSIX line endings

number of columns and types based on col_types and
col_names even if the file is empty (#297).
vroom() no longer mis-indexes files read from
connections with windows line endings when the two line endings falls on
separate sides of the read buffer (#331)

and col_names is a character (#316)

and readr are both loaded (#303)

col_types that have been repaired (#311)
vroom() no longer inadvertently calls
.name_repair functions twice (#310).
vroom() is now more robust to quoting issues when
tracking the CSV state (#301)

methods::setOldClass() (r-dbi/DBI#345)

represents decimal seconds since the Unix epoch.
col_numeric() now supports
grouping_mark and decimal_mark that are
unicode characters, such as U+00A0 which is commonly used as the
grouping mark for numbers in France
(https://github.com/tidyverse/readr/issues/796).

argument.

parse errors (#326)

called on a readr object (#308).

(#318)
Fix an inadvertent performance regression when reading values (#309)
n_max argument is correctly respected in edge cases
(#306)
factors with implicit levels now work when fields are quoted, as intended (#330)
Guessing double types no longer unconditionally ignores leading
whitespace. Now whitespace is only ignored when trim_ws is
set.
vroom now tracks indexing and parsing errors like readr. The
first time an issue is encountered a warning will be signaled. A tibble
of all found problems can be retrieved with
vroom::problems(). (#247)
Data with newlines within quoted fields will now automatically revert to using a single thread and be properly read (#282)
NUL values in character data are now permitted, with a warning.
New vroom_write_lines() function to write a
character vector to a file (#291)

style newlines (#263).

so you can control the encoding of the file (#218)
vroom_write() now supports the append
argument with R connections (#232)

Added a NEWS.md file to track changes to the
package.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
