zip 2.3.1

• The zip shared library now hides its symbols (on platforms that support
  this), to avoid name clashes with other libraries (#98).

zip 2.3.0

• zip now handles large zip files on Windows (#65, #75, #79, @weshinsley).

• zip now behaves better for absolute paths in mirror mode, and when the
  paths contain a : character (#69, #70).

• zip::unzip() now uses the process's umask value (see umask(2)) on Unix
  if the zip file does not contain Unix permissions (#67).

• Fix segmentation fault when zip file can't be created (#91, @zeehio)

• Fix delayed evaluation error on zipfile when zip::zip()
  is used (#92, @zeehio)

• New deflate() and inflate() functions to compress and uncompress
  GZIP streams in memory.

zip 2.2.2

• No user visible changes.

zip 2.2.1

• No user visible changes.

v2.2.0

• Header values (of version made by and external attributes) are now
  correctly read and written on big-endian systems (#68).

• zip_list() now also returns crc32 and offset (#74, @jefferis).

v2.1.1

This version has no user visible changes.

v2.1.0

• unzip_process() now does not fail randomly on Windows (#60).

• Now all functions handle Unicode paths correctly, on Windows
  as well (#42, #53).

• unzip_process() now works when R library is on different drive
  than exdir on Windows (#45)

• zip functions now have a mode argument to choose how files and
  directories are assembled into the archive. See the docs for
  details.

• zip functions now have a root argument, zip changes the working
  directory to this before creating the archive, so all files are
  relative to root.

• zip() and zip_append() are not deprecated any more, as it was
  hard to achieve the same functionality with the other zip functions.

v2.0.4

• unzip_process() prints better error messages to the standard error,
  and exits with a non-zero status, on error.

v2.0.3

• zipr() and zipr_append() get an include_directories = TRUE
  argument, that can be used to omit directory entries from the zip
  archive. These entries may cause problems in MS Office docx files (#34).

v2.0.2

• zip_process() and unzip_process() can now pass extra arguments to
  processx::process (#32).

• unzip_process() now makes sure the exdir path is created with
  forward slashes on Windows, mixing forward and backward slashes can
  cause errors.
