New minor version.

Noteworthy changes in this release:

  • Member names containing '..' components are now skipped when extracting.

This fixes tar's behavior to match its documentation, and is a bit safer when extracting untrusted archives over old files (an unsafe practice that the tar manual has long recommended against).

  • Report erroneous use of position-sensitive options.

During archive creation or update, tar keeps track of positional options (see the manual, subsection 3.4.4 "Position-Sensitive Options"), and reports those that had no effect. For example, when invoked as

tar -cf a.tar . --exclude '*.o'

tar will create the archive, but will exit with status 2, having issued the following error message

tar: The following options were used after non-optional arguments in archive create or update mode. These options are positional and affect only arguments that follow them. Please, rearrange them properly. tar: --exclude '*.o' has no effect tar: Exiting with failure status due to previous errors

  • --numeric-owner now affects private headers too.

This helps the output of 'tar' to be more deterministic.

  • Fixed the --delay-directory-restore option

In some cases tar would restore the directory permissions too early, causing subsequent link extractions in that directory to fail.

  • The --warnings=failed-read option

This new warning control option suppresses warning messages about unreadable files and directories. It has effect only if used together with the --ignore-failed-read option.

  • The --warnings=none option now suppresses all warnings

This includes warnings about unreadable files produced when --ignore-failed-read is in effect. To output these, use --warnings=none --warnings=no-failed-read.

  • Fix reporting of hardlink mismatches during compare

Tar reported incorrect target file name in the 'Not linked to' diagnostic message.
