	* 0.15 release (update for Gnumeric 1.12.21+)

2014-09-17  Albert Graef  <aggraef@gmail.com>

	* 0.14 release

	* Pass the -mcpu=generic option to llc when batch-compiling Pure
	scripts, to prevent illegal instructions depending on the build
	host's cpu type.

2013-09-01  Albert Graef  <aggraef@gmail.com>

	* pure-loader/pure-gnumeric.c: Ported the OpenGL rendering code to
	GTK3 / GtkGLExt 3.0 (https://github.com/tdz/gtkglext). This
	compiles cleanly now, but doesn't seem to work yet (GtkGLExt3
	apparently creates bad GLXDrawables). Until this is fixed, we keep
	the OpenGL support disabled by default. This might just be a
	driver-related issue on my system, though, so YMMV. If you want to
	give it a try then make sure you have GtkGLExt3 installed and
	uncomment the GtkGLExt configuration line in the Makefile before
	running make.

	* Makefile, examples/*/Makefile, pure-loader/pure-loader.c:
	Various fixes for compatibility with Gnumeric 1.12. NOTE: This
	version won't compile with Gnumeric <= 1.10 any more because of
	changes in the Gnumeric plugin API. So if you need Gnumeric 1.10
	support then you'll have to stick to version 0.12 of this module.

	* 0.12 release

2012-06-11  Albert Graef  <Dr.Graef@t-online.de>

	* pure-gnm/pure-gnm.pure: Add a script which generates plugin.xml
	files from plugin scripts.

2012-06-07  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-loader.c: Allow all loaded Pure scripts to be
	edited instead of just the last one.

2012-06-06  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-loader.c: Some substantial improvements in the
	handling of plugin scripts. Plugin scripts may now be specified in
	the plugin.xml with a pathname so that they can be installed in
	any directory (not necessarily the plugin directory).

	The pathname may either start with ~/, in which case it is taken
	relative to the user's home directory, or it may be an absolute
	pathname which is taken as is. Other pathnames are interpreted
	relative to the plugin directory (i.e., the directory containing
	the plugin.xml file).

	The pathname *must* now be specified with the proper filetype; the
	.pure suffix is *not* added automatically any more.

	In addition, the plugin script now gets loaded in the *script*
	directory (which may be different from both gnumeric's cwd and the
	plugin directory), so that it can find other files that it may
	need.

2011-03-04  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-loader.c (pure_async_func_init): Add proper
	exception handling to the child process for asynchronous data
	sources. This fixes a bug which causes spurious extra datasources
	to be created in the child process if a datasource bails out with
	a Pure exception.

2010-10-23  Albert Graef  <Dr.Graef@t-online.de>

	* 0.8 release

2010-04-17  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c: Gnumeric 1.10 compatibility
	fixes. Resolves issue #26 reported by asitdepends.

2009-10-09  Albert Graef  <Dr.Graef@t-online.de>

	* Makefile, pure-loader/pure-gnumeric.c,
	pure-loader/pure-loader.c: Various windows compatibility
	fixes. The module compiles cleanly on Windows now, but refuses to
	load. :(

2009-10-06  Albert Graef  <Dr.Graef@t-online.de>

	* 0.5 release

	* pure-loader/pure-loader.c (pure_reload, gl_reinit): More fixes
	to the interpreter reinitialization. Destroy the OpenGL windows,
	too, when reinitializing for a new interpreter instance, so that
	we do not invoke stale callbacks from an old interpreter instance.

2009-10-04  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c (pure_trigger): Reworked the trigger
	function so that the callbacks take an additional data parameter
	passed to trigger. The callbacks are now invoked by just passing
	the callback data to them (no quote, eval any more) so that we can
	avoid pure_evalx here, too.

2009-10-03  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c (call_pure_function): Reworked so
	that we avoid pure_evalx which is a performance hog. NOTE: This
	requires Pure 0.36 or later.
	(get_frame_sheet et al): Use the sheet object's new 'name'
	property to look for widget names. NOTE: You'll need Gnumeric
	1.9.14 or later to make this actually work.

	* pure-loader/pure-loader.c (pure_reload): Fix broken interpreter
	reinitialization.
	(pure_async_func_stop): Remove datasource entry from hash table
	when destroying it.

2009-10-02  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c (pure_write_blob, pure_read_blob):
	Encode key,value pair as a list instead of a tuple, so that we
	don't choke on tuple values.

2009-09-30  Albert Graef  <Dr.Graef@t-online.de>

	* 0.4 release

	* pure-loader/pure-gnumeric.c
	(sheet_widget_list_base_get_result_link): Use
	sheet_widget_list_base_get_result_dep in the Gnumeric API, to
	avoid depending on SheetObject internals.
	(sheet_widget_list_base_get_content_link): Provide an interface to
	also get the content link.
	(pure_sheet_objects): Return the content link in the label field.
	(pure_get_cell_text, pure_get_range_text): New functions to get
	the entered text of a cell or range.
	(pure_get_cell_format, pure_set_cell_format)
	(pure_get_range_format, pure_set_range_format): New functions to get
	and set the format of a cell or range.

2009-09-28  Albert Graef  <Dr.Graef@t-online.de>

	* 0.3 release

	* pure-loader/pure-gnumeric.c (pure2value): Gnumeric goes bonkers
	on empty arrays, return empty value for empty Pure lists and
	matrices instead.

	* pure-loader/pure-gnumeric.c, pure-loader/pure-loader.c: Various
	bugfixes in OpenGL rendering. Overhaul management of OpenGL
	windows so that multiple views are supported.

	* pure-loader/pure-gnumeric.c (pure_sheet_objects): Plug various
	memleaks on Gnumeric expression nodes. Also fix up information
	about list and combo widgets so that the linked cell is included.

	* pure-func/pure_func.pure (pure_objects): Fix up realized check
	for widgets.

	* pure-loader/pure-gnumeric.c (pure_sheet_objects): Various
	bugfixes. In particular, a sheet object may be associated with
	different widgets in different views, so we return a list of
	widgets in the last component of the object description now.

2009-09-26  Albert Graef  <Dr.Graef@t-online.de>

	* pure-func/pure_func.pure (pure_shell): Renamed from pure_evalstr.

	* pure-loader/pure-gnumeric.c (pure_set_range_text): New function,
	analogous to pure_set_cell_text, but handles cell ranges.
	(pure_set_cell_text): Renamed from pure_set_text.

2009-09-24  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c (get_frame): Look for frame widgets
	first in the current sheet, then in all sheets of the same
	workbook.
	(pure_sheet_objects): List objects for all sheets of the workbook.

	* pure-loader/pure-loader.c, pure-loader/pure-gnumeric.c:
	Refactoring, bugfixes.

	* Makefile, pure-loader/pure-gnumeric.c,
	pure-loader/pure-loader.c, pure-func/pure_func.pure: OpenGL
	support (requires GtkGLExt).

2009-09-22  Albert Graef  <Dr.Graef@t-online.de>

	* examples/widgets.gnumeric: Added example.

	* pure-func/pure_func.pure (pure_objects): Add pure_objects
	function to show a table with information about the objects in the
	current sheet.

	* pure-loader/pure-gnumeric.c (pure_trigger): Add a function which
	repeatedly evaluates a given condition and evaluates and returns
	another value as soon as the condition becomes true.

2009-09-21  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c (pure_sheet_objects): Add a function
	which reports various useful information about the widget objects
	in the current sheet.

2009-09-18  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-loader.c (gplp_load_base): Add the pure-func
	plugin directory to Pure's include path when creating the
	interpreter. This lets the user import pure_func.pure and other
	scripts distributed with gnumeric-pure if needed.

	* pure-loader/pure-gnumeric.c (pure_read_blob): Bugfixes in blob
	reader (asynchronous data source).
	(pure_parse_range, pure_make_range): Add functions to convert
	between textual range specifications and tuples.

2009-09-17  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c (pure2value): Add support for int
	matrices.
	(pure_this_cell, pure_get_cell, pure_set_cell, pure_set_text,
	pure_get_range, pure_set_range): Add basic cell inspection and
	manipulation operations.

	* pure-loader/pure-loader.c (gplp_func_desc_load): Check function
	signatures for validity.

	* pure-loader/pure-gnumeric.c (pure_gnmcall): Check arguments for
	compatibility.

2009-09-16  Albert Graef  <Dr.Graef@t-online.de>

	* pure-loader/pure-gnumeric.c: Add suport for cell ranges ("r" type).

	* Makefile: version bump

	* 0.2 release, ChangeLog started
