-2002-12-09 added list_empty() and hash_empty() functions
+ NOTE:
+ All releases below marked (Chris Frey) are maintenance releases
+ done by Chris Frey, temporarily stepping in for Mark Roth.
+ These releases are git-based only and can be found at:
+ http://repo.or.cz/w/libtar.git
-2002-09-12 fixed list_iterate function to return -1 if it gets
- an invalid argument
+ Both git downloads and tarball downloads are possible at this site.
- include <config.h> and <compat.h> from source files, not
- from header file, since header file is sometimes
- installed as part of a user-visible API
- (those APIs should eventually be redesigned without the
- listhash code being publicly visible, but for now we
- need to accomodate this)
-2002-07-07 modified list iterate function to return int
- (returns -1 if plugin function returns -1)
+libtar 1.2.20 - 2013/10/09 (Chris Frey)
+-------------
+ Added extern "C" protectors to listhash.h
+ Added autoconf checks for __thread compiler support
+ Fixed size_t overflow bug, as reported by Timo Warns
+ Fixed thread-safe bug in th_get_pathname() (Sergey Zhitomirsky)
+
+
+libtar 1.2.19 - 2012/12/11 (Chris Frey)
+-------------
+ Removed varargs.h and all dependencies, to avoid user compile errors
+
+ Fixed some short int / int compiler warnings in va_arg() usage
+
+ Fixed some gcc built-in compiler warnings
+
+ Changed autoconf support code from AC_RUN_ to AC_COMPILE_ to fix
+ issues reported during cross-compiling.
+
+ Applied most of Jan Cermak's const char* function argument patch.
+
+
+libtar 1.2.18 - 2012/08/02 (Chris Frey)
+-------------
+ Added more forgiving CRC checking logic when reading tar files
+
+ Note: If your application uses the macro th_crc_ok(), then to gain full
+ advantage of the changes in this version, you will need to recompile
+ your application against the new headers. Otherwise, the library is
+ drop-in replaceable, as usual.
+
+
+libtar 1.2.17 - 2012/07/24 (Chris Frey)
+-------------
+ Applied Tim Band's checksum patch from mailing list (thanks!)
+
+

+-------------
+Chris Frey (1):
+ Fixed truncation check, so 100 char names get GNU extension support when enabled
+
+
+libtar 1.2.13 - 2011/06/13 (Chris Frey)
+-------------
+Chris Frey (10):
+ Fixed incorrect URL in readme
+ Added autoconf/ as macro dir
+ Added autogen.sh script to build a fresh configure
+ Renamed autoconf/aclocal.m4 to psg.m4 so aclocal isn't so confused
+ Removed m4 includes, and straightened out [] m4 quoting for modern autoconfs
+ Removed auto-generated files
+ Added datarootdir to Makefile.in's
+ Fixed header warnings
+ Applied Marcin Gibula's patch fixing tar_extract_glob()
+ Changed root Makefile.in to Makefile.am, which make autoreconf workable
+
+Glenn McGrath (1):
+ Use libtool to build dynamic library
+
+James Morrison (1):
+ Document stupidity of tartype_t in libtar.c.
+
+Magnus Holmgren (1):
+ Escape hyphens that should be minus signs in man pages.
+
+Per Lidén (2):
+ Fix memory leak in th_get_pathname
