Apache Commons Compress 1.8.1 发布，该版本修复了以下一些 bug：
o COMPRESS-270: The snappy, ar and tar inputstreams might fail to read from a non-buffered stream in certain cases. o COMPRESS-277: IOUtils#skip might skip fewer bytes than requested even though more could be read from the stream. o COMPRESS-276: ArchiveStreams now validate there is a current entry before reading or writing entry data. o ArjArchiveInputStream#canReadEntryData tested the current entry of the stream rather than its argument. o COMPRESS-274: ChangeSet#delete and deleteDir now properly deal with unnamed entries. o COMPRESS-273: Added a few null checks to improve robustness. o COMPRESS-278: TarArchiveInputStream failed to read archives with empty gid/uid fields. o COMPRESS-279: TarArchiveInputStream now again throws an exception when it encounters a truncated archive while reading from the last entry. o COMPRESS-280: Adapted TarArchiveInputStream#skip to the modified IOUtils#skip method. Thanks to BELUGA BEHR.
此外对 org.tukaani:xz 的依赖不再必须。
