Hash: SHA1

The Apache Commons Team is pleased to announce the release of Apache
Commons Compress 1.7.

The Apache Commons Compress Library defines a Java API for working with
ar, cpio, tar, zip, 7z, arj, dump, gzip, pack200, bzip2, lzma, snappy, Z
and xz files.

Version 1.7 introduces read-only support for Snappy and traditional Unix
.Z compress but it also fixes important bugs inside the tar and 7z
packages.

Source and binary distributions are available for download from the
Apache Commons download site:

http://commons.apache.org/proper/commons-compress/download_compress.cgi

When downloading, please verify signatures using the KEYS file available
at the above location when downloading the release.

Changes in this version include:

New features:
o Read-Only support for Snappy compression.
  Issue: COMPRESS-147. Thanks to BELUGA BEHR.
o Read-Only support for .Z compressed files.
  Issue: COMPRESS-243. Thanks to Damjan Jovanovic.
o ZipFile and ZipArchiveInputStream now support reading entries
  compressed using the SHRINKING method. Thanks to Damjan Jovanovic.
o GzipCompressorOutputStream now supports setting the compression
  level and the header metadata (filename, comment, modification time,
  operating system and extra flags)
  Issue: COMPRESS-250. Thanks to Emmanuel Bourg.
o ZipFile and ZipArchiveInputStream now support reading entries
  compressed using the IMPLODE method.
  Issue: COMPRESS-115. Thanks to Emmanuel Bourg.
o ZipFile and the 7z file classes now implement Closeable and can be
  used in try-with-resources constructs.

Fixed Bugs:
o SevenZOutputFile#closeArchiveEntry throws an exception when using
  LZMA2 compression on Java8.  Issue: COMPRESS-241.
o 7z reading of big 64bit values could be wrong.
  Issue: COMPRESS-244. Thanks to Nico Kruber.
o TarArchiveInputStream could fail to read an archive completely.
  Issue: COMPRESS-245.
o The time-setters in X5455_ExtendedTimestamp now set the
  corresponding flags explicitly - i.e. they set the bit if the valus
  is not-null and reset it otherwise.  This may cause
  incompatibilities if you use setFlags to unset a bit and later set
  the time to a non-null value - the flag will now be set.
  Issue: COMPRESS-242.
o SevenZOutputFile would create invalid archives if more than six
  empty files or directories were included.  Issue: COMPRESS-252.
