+version 1.13.10 - Paul Eggert, 1999-08-20.
+
+* `tar' now uses signed base-64 when outputting header values that are
+ out of the range of the standard unsigned base-8 format. This
+ affects archive members with negative timestamps or uids, and
+ archive members 8 GB or larger. The new tar archives cannot be read
+ by traditional tar, or by older versions of GNU tar. Use the
+ --old-archive option to revert to the old behavior, which uses
+ unportable representations for negative values, and which rejects
+ large files.
+
+version 1.13.9 - Paul Eggert, 1999-08-18.
+
+* `tar' now writes two zero blocks at end-of-archive instead of just one.
+ POSIX.1 requires this, and some other `tar' implementations check for it.
+
+* `tar' no longer silently accepts a block containing nonzero checksum bytes
+ as a zero block.
+
+* `tar' now reads buggy tar files that have a null byte at the start of a
+ numeric header field.
