File Release Notes and Changelog

Release Name: 0.9.7

Notes:
bear 0.9.7 (2007-12-31)

  * Bug fixes.  Fixed some segfaults on invalid parameters, failure to
    obey command-line parameters (quiet, verbose), corrected error
    messages.

  * Experimental features.  New 'mtsum' module for computing
    McShane-type sums over the tree of Markov triples.

  * Improved, revised documentation.

  * Code improvements.  Additional comments, include string.h
    for memcpy(), corrections to mtsum.h comments.  Eliminated some
    casting and array subscripting warnings.

	* bear 0.9.7

2007-05-28  David Dumas  <daviddumas@gmail.com> 

	* src/bear/linear.c: Include string.h, since memcpy is used here. 

	* src/bear/interp_trace.c (it_alloc): Cast to gsl_interp_type to
	eliminate warning about discarding const qualifier.

	* src/bear/heun_gsl.c (heun_gsl_jacobian): Fix two-dimensional
	array subscripting.  Now manually compute offset as 4*i+j.

	* src/bear/anosov.c: Include string.h, since memcpy is used here.
	(find_fixed): Add function pointer casts to prevent warning.

	* doc/bear-ref.tex: Extensive updates to describe changes and new
	features since 0.9.6 release

	* src/bear/mtsum.h: remove comments that incorrectly mention
	discreteness module, rather than mtsum (left over from conversion)

	* src/bear/lua_def.c (bear_lua_h5write_holonomy): report correct
	module name in error messages (holonomy, not h5holonomy)

	* src/bear/h5pathspec.c: add comments describing parse routines
	(h5ps_dataset_name): fix h5ps_dataset_name so it operates on its
	parameter, rather than an uninitialized pointer

	* src/bear/lua_def.c (bear_lua_bowditch): fix segfault on call to
	bowditch.run when there is no holonomy data available (check for
	null pointer) AND corresponding changes to mtsum, h5holonomy.

	* src/bear/bers2.c (bers2): do not print status line in quiet
	mode; also fix dereferencing of an uninitialized pointer in that
	case.

2007-02-11  David Dumas  <daviddumas@gmail.com>

	* src/bear/schwarz.c: check for failed contour driver hash; fixes
	segfault when the string passed in the control structure is invalid.

2006-05-24  David Dumas  <daviddumas@gmail.com>

	* src/bear/mtsum.c (mtsum): Add comments.

2005-09-19  David Dumas  <daviddumas@gmail.com>

	* bear: added routines to register mtsum and scalar namespaces
	with lua.

	* bear: h5scalar.c, h5scalar.h add module to write an array of
	doubles to an HDF5 data file.

	* bear: mtsumi.c, mtsumi.h created to iterate the routine from
	mtsum over the elements of a holonomy arrary as produced by bers,
	bers2

	* bear: added mtsum.c, mtsum.h, providing framework for summing
	the values of a function over the nodes of the Markov tree

	* bear: debug statements from h5discreteness-related functions in
	lua_def.c now contain correct function names.
