	(UPDATED-FOR): Set to 1.11. I think the manual should be updated
	with all user-visible changes.

	* examples/nettle-openssl.c (NCOMPAT): Disable openssl backwards
	compatibility.

	precomputing the offset between src and dst.

	* tools/Makefile.in (.c.$(OBJEXT)): Removed redundant -I.. flag.

	* x86/arcfour-crypt.asm (nettle_arcfour_crypt): Replaced addb ->

	rsa-encrypt. Needed for the test to work on systems with no
	/dev/urandom.

2004-02-12  Niels Mller  <niels@s3.kth.se>

	* configure.ac (CPPFLAGS, LDFLAGS): No spaces after -I and -L, as
	some C compilers, in particular True64 cc, don't like that.

	dependency on gmp.h.
	(pgp_put_mpi): Condition on HAVE_LIBGMP.

	nettle_des_set_key for referring to Nettle's function.

	not replace it.

2003-01-30  Niels Mller  <nisse@cuckoo.hack.org>

	* Makefile.am (libnettleinclude_HEADERS): Added realloc.h.
	(libnettle_a_SOURCES): Added buffer-init.c and realloc.c.

	* sexp.c (sexp_iterator_exit_lists): New function, #if:ed out for
	now.

	* desdata.c: Include config.h, to get definition of UNUSED.
	* shadata.c: Likewise.

	* buffer.c (nettle_buffer_grow): New function, replacing
	grow_realloc.
	(nettle_buffer_clear): Rewritten to use buffer->realloc.

	* buffer.h (struct nettle_buffer): Replaced the GROW function
	pointer with a nettle_realloc_func pointer and a
	void *realloc_ctx.
	(NETTLE_BUFFER_GROW): Deleted macro, use function instead.

	* buffer-init.c (nettle_buffer_init): Moved to a separate file.

	* realloc.c (nettle_realloc): New function.
	(nettle_xrealloc): New function.

	* realloc.h (nettle_realloc_func): New typedef.

2002-11-16  Niels Mller  <nisse@cuckoo.hack.org>

	* sexp2dsa.c, sexp2rsa.c: (macro GET): Check sign of parsed
	numbers.

	* sexp2bignum.c (nettle_mpz_set_sexp): In the first check against
	limit, added some margin to allow for sign octets.

2002-11-15  Niels Mller  <nisse@cuckoo.hack.org>

	* testsuite/testutils.h (LDATA): Use sizeof instead of strlen. Now
	handles strings including NUL-characters. But works only with
	literals and character arrays, no char pointers.
	(LLENGTH): New macro, computing length the same way as LDATA.

	* testsuite/sexp-test.c (test_main): Test sexp_iterator_get_uint32.

	* testsuite/sexp-format-test.c (test_main): Check that %i and %b
	generate leading zeroes when needed. Check that %b handles
	negative numbers.

	* testsuite/rsa2sexp-test.c (test_main): Updated test, one leading
	zero is needed in the private key expression. In verbose mode,
	print the generated keys.

	* testsuite/sexp2rsa-test.c (test_main): Added a leading zero in
	the private key expression.

	* testsuite/bignum-test.c (test_bignum): Use
	nettle_mpz_init_set_str_256_s.
	(test_size): New function.
	(test_main): Test size computation and formatting of negative
	numbers.

	* sexp2bignum.c (nettle_mpz_set_sexp): Use
	nettle_mpz_set_str_256_s, to handle negative numbers correctly.

	* sexp-format.c (sexp_vformat): For %i, output a leading zero when
	needed to get a correct, positive, sign. For %b, use
	nettle_mpz_sizeinbase_256_s, to handle negative numbers properly.

	* bignum.c (nettle_mpz_sizeinbase_256_s): New function.
	(nettle_mpz_sizeinbase_256_u): New name, was
	nettle_mpz_sizeinbase_256. Updated all callers.
	(nettle_mpz_to_octets): New function.
	(nettle_mpz_get_str_256): Handle negative numbers.
	(nettle_mpz_from_octets): New function.
	(nettle_mpz_set_str_256_u): New name, was nettle_mpz_set_str_256.
	(nettle_mpz_init_set_str_256_u): New name, was
	nettle_mpz_init_set_str_256.
	(nettle_mpz_set_str_256_s): New function, handling negative two's
	complement numbers.
	(nettle_mpz_init_set_str_256_s): And an init variant.

	* sexp.c (sexp_iterator_get_uint32): New function.

2002-11-10  Niels Mller  <nisse@cuckoo.hack.org>

	* testsuite/sexp-conv-test: Use input files without any trailing
	newline character, in order to stress the end of file handling.

	* tools/sexp-conv.c (sexp_get_token_string): Fixed end of file
	handling.
	(sexp_get_string): Fixed end of encoding/end of file handling.
	(parse_options): Check for negative width and complain.

	* tools/sexp-conv.c: Use supplied getopt.
	(werror): New function.
	(sexp_output_hash_init): New function.
	(sexp_put_char): Made base64 linebreaking configurable.
	Implemented hashing.
