+2005-07-29  Vincent Lefevre  <Vincent.Lefevre@loria.fr>
+
+	* set_ld.c:
+	Forgot to keep the old value of d when computations need to be redone.
+	[2.1 branch]
+
+	* tests/tset_ld.c: Fixed the tests. [2.1 branch]
+
+	* set_ld.c:
+	Support C implementations giving an incorrect value for the precision
+	of long double or where long doubles are implemented with FP expansions
+	(like under Mac OS X). Not tested yet... [2.1 branch]
+
+2005-07-26  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* Makefile.am, mpfr.h, mpfr.texi, stack_interface.c, tests/Makefile.am, tests/tstckintc.c:

+	* mpfr-impl.h: Fix and clean up logging for GCC 4.0.x
+
+	* mpfr-impl.h: Clean up code.
+
+	* README.dev, logging.c, mpfr-impl.h: Improve logging:
+	 + The file is not created if there is nothing to log.
+	 + Add new ENVIRONMENT variables: MPFR_LOG_ALL and MPFR_LOG_STAT.
+
+	* atan.c: Add experimental code (Disabled).
+
+	* strtofr.c: Fix comment

+
+2005-07-22  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* erfc.c: Fix bug for high values of input (assertion failed)
+	because erf(x) ~ 1, so 1-erf(x) ~ 0, and we can't
+	get the EXP of tmp.
+
+2005-07-18  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* update-version: Fix bug (AC_INIT version wasn't updated).

+
+	* BUGS, acinclude.m4, tests/tests.c:
+	In the tests, set the locale to the current one. This allows to test
+	MPFR under various locales, showing a bug in the parse_string function
+	due to the use of the strncasecmp function ('i' and 'I' don't match
+	with LC_ALL="tr_TR.ISO8859-9").
+
+2005-07-07  Patrick Pelissier  <Patrick.Pelissier@loria.fr>

+	* atan.c: Simplify a condition which was always true.
+	(p is always negative).
+
+	* atan.c: Add assertion.
+
+	* atan.c: Simplify code for final step (when i== n0):
+	since we do n0-i=0 steps, atan(Ak/2^k) ~= Ak/2^k.
+	So we could speed up the final computation (9% faster).
+
+	* atan.c: Optimize: when computing arctan(p/2^r) simplify
+	p/2^r if p is even.
+	Clean up and remove tabi table. It was useless.
+
+2005-06-22  Patrick Pelissier  <Patrick.Pelissier@loria.fr>

+	Fix potential (?) overflow for very large precision.
+	Various tiny optimizations
+	Improve the initial estimation of the needed precision.
+
+	* Makefile.am, constant.c, log.c, mpfr-impl.h:
+	Extract constants (__gmpfr_one, two and four) from log.c to constant.c
+	Fix bug in MPFR_SET_ONE.
+
+	* sin.c: Remove a space.

+
+	* NEWS: Typography + spelling.
+
+	* NEWS: Note that mpfr_out_str has slightly changed.
+
+2005-05-16  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* TODO: asin, atan, atanh are not slow anymore for small input.
+	Remove it in the TODO.
+
+2005-05-14  Vincent Lefevre  <Vincent.Lefevre@loria.fr>
+
+	* atanh.c: Fixed a bug due to a typo on a variable name. It produced a
+	segmentation fault in the tests on Linux/ppc (uninitialized data were
+	read), not always reproducible when stepping with gdb.
+
+	* mpfr.texi: Ported description of mpfr_hypot to the 2.1 branch.
+
+2005-05-13  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* expm1.c, log1p.c: Add support for MPFR_FAST_COMPUTE_IS_SMALL_INPUT
+
+	* asin.c, asinh.c, atan.c, atanh.c, sin.c, sinh.c, tan.c, tanh.c:
+	Add support for FAST_COMPUTE_IS_SMALL_INPUT.
+
+	* atan.c: Add round_near_x support for small arguments.
+
+	* Makefile.am, round_near_x.c:
+	Add new internal function mpfr_round_near_x.
+
+2005-05-13  Paul Zimmermann  <Paul.Zimmermann@loria.fr>
+
+	* mpfr.texi: added missing documentation for mpfr_hypot
+
+2005-05-13  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* tests/texceptions.c: Add a \n for all error strings.
+
+	* version.c: Fix copyright date.
+
+	* mpfr-impl.h, mpfr.h, tests/tconst_pi.c, tests/texp.c:
+	Fix some problems when you define mpfr_prec_t to be an unsigned short.
+	Now all tests passed when mpfr_prec_t is defined to be an unsigned short
+	on a 32 bit CPU!
+
+2005-05-12  Vincent Lefevre  <Vincent.Lefevre@loria.fr>
+
+	* hypot.c: Replaced -2 by -MPFR_EVEN_INEX. [2.1 branch]
+
+	* hypot.c: Added a comment about the bug fix. [2.1 branch]
+
+	* BUGS, hypot.c, tests/thypot.c:
+	Fixed bug in mpfr_hypot + testcase. [2.1 branch]
+
+	* exp_2.c: Detect/avoid potential integer overflows.
+
+2005-05-12  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* tests/texp.c: Fix typos.
+
+2005-05-11  Patrick Pelissier  <Patrick.Pelissier@loria.fr>
+
+	* tests/texp.c, exp3.c: Same patch for exp_3.
+
+	* exp.c, exp_2.c, tests/texp.c:
+	Fix bug when exp(x) is near the limit of an overflow or an
+	underflow (mpfr_exp_2 didn't allow an overflow/underflow in its
+	internal loop).
+	Add corresponding test case. exp_3 may need similar patchs.
+
+2005-05-11  Vincent Lefevre  <Vincent.Lefevre@loria.fr>
+
+	* ChangeLog:
+	Update (with reformatting so that the logs are readable on 80 columns).

 	* mul.c, tests/tmul.c: Fix bug due to wrong assertion.
