+2007-01-23  Brian Gough  <bjg@network-theory.co.uk>
+
+	* betainv.c (gsl_cdf_beta_Pinv): avoid generating a NaN for lx > 0
+
+2006-04-18  Brian Gough  <bjg@network-theory.co.uk>
+
+	* betainv.c (gsl_cdf_beta_Qinv): fix prototype const
+
+2006-03-07  Brian Gough  <bjg@network-theory.co.uk>
+
+	* poisson.c: added poisson cdf
+
+	* nbinomial.c: added negative binomial cdf
+
+	* hypergeometric.c: added hypergeometric cdf
+
+	* geometric.c: added geometric cdf
+
+	* binomial.c (gsl_cdf_binomial_Q): added binomial cdf
+
+	* test.c: added discrete function tests
+
+	* gamma.c (gsl_cdf_gamma_P, gsl_cdf_gamma_Q): clean up unused
+	code, ensure that branches make P+Q=1 always true
+
+	* fdistinv.c (gsl_cdf_fdist_Pinv): use P instead of p for consistency
+
+	* fdist.c (gsl_cdf_fdist_Q): use Q instead of P for consistency
+
+	* beta.c (gsl_cdf_beta_Q): use Q instead of P for consistency
+
+2006-02-27  Brian Gough  <bjg@network-theory.co.uk>
+
+	* fdistinv.c (gsl_cdf_fdist_Pinv, gsl_cdf_fdist_Qinv): added
+	inverse functions
+
+	* betainv.c (gsl_cdf_beta_Pinv, gsl_cdf_beta_Qinv): added inverse
+	functions
+
+	* tdistinv.c (gsl_cdf_tdist_Qinv, gsl_cdf_tdist_Pinv): max 32
+	iterations, prevent infinite loop
+
+	* gammainv.c (gsl_cdf_gamma_Qinv, gsl_cdf_gamma_Pinv): max 32
+	iterations, prevent infinite loop
+
+2005-06-20  Brian Gough  <bjg@network-theory.co.uk>
+
+	* test.c: removed tests using subnormal values, since they tend to
+	fail when extended precision registers are not available.	
+
+2004-10-26  Brian Gough  <bjg@network-theory.co.uk>
+
+	* exppow.c: added exppow distribution
+
+2004-10-01  Brian Gough  <bjg@network-theory.co.uk>
+
+	* beta.c (gsl_cdf_beta_P, gsl_cdf_beta_P): return consistent
+	results for out of range values.
+
+2003-08-27  Brian Gough  <bjg@network-theory.co.uk>
+
+	* gauss.c: use parentheses around constant macros to avoid -(-X)
+	being interpreted as --X
+
+2003-07-27  Brian Gough  <bjg@network-theory.co.uk>
+
+	* gumbel1.c (gsl_cdf_gumbel1_Q): use pow in place of exp since
+	compilers seem to handle overflow better in this case (perhaps
+	because it is not an intrinsic function).
+
+	* gumbel2.c (gsl_cdf_gumbel2_P): handle case of x = 0 explicitly
+	(gsl_cdf_gumbel2_Q): handle case of x = 0 explicitly
+
+2003-07-22  Brian Gough  <bjg@network-theory.co.uk>
+
+	* gamma.c (gsl_cdf_gamma_P): Peizer and Pratt approximation for
+	large a seems to be inaccurate in tails
+	(gsl_cdf_gamma_Q): Peizer and Pratt approximation for large a
+	seems to be inaccurate in tails
+
+	* test.c (main): added test for large a for gamma
+
+	* cauchyinv.c (gsl_cdf_cauchy_Qinv): corrected limiting value for
+	Q=1
+
+	* added Cumulative Distribution functions from savannah.gnu.org
