v2.9.6.1

Included with L3DT v2.9 build 14
Fixed filter graph version number handling.
Automated creation of map project if uninitialised.
Closed threaded progress box on completion of graph.

v2.9.0.9

Added automatic type casting between pins of dissimilar types without need for intermediary casting filters.
Allowed variant↔variant pin connections, using an intermediary casting filter to define connection type.

v2.8.0.4

Added ability to define filters from text/script files (extension is '.zfilter').
Added automatic data type casting, using 'Cast' intermediate filter.
Added ZeoScript filter, to allow custom operations.
Added 'disable filter' option.
Added filter 'copy' and 'paste' options.
Alpha sorting of filters in 'add filter' window.
Other changes are documented in L3DT v2.9 change log.

v2.7.4.4

In FilterTreeDlg:
- Added help link in bottom-right hand corner, as per L3DT standard UI.
In ZeoGraphWnd:
- Implemented graph panning.

v2.7.4.3

For ZeoGraphWnd:
- Added 'rename filter' menu option.
- Always prompt for filename when attempting to save 'default.zgraph'.
- Changed 'run' and 'stop' buttons to triangle and square, respectively (using VCR metaphor, rather than traffic lights).
- Check run state when editing options, connecting pins, loading graphs, and creating new graphs.
- Clicking on the run button when the graph is running will stop the graph (button acts as toggle).
- Changed the name of the graph that is automatically loaded on startup from 'default.zgraph' to 'start.zgraph'.
Filters:
- Split 'scalar math' into 'add', 'subtract', 'multiply', 'divide', 'power', 'min' and 'max' filters.
- Added nice options window to 'Project.GetProjectMap' and 'Project.SetProjectMap'.
- Added 'Project.GetProjectMap2' and 'Project.SetProjectMap2', with string inputs for map name.

v2.7.4.1

For ZeoGraphWnd:
- Added 'copy to clipboard' menu option.
- Added 'connect to…' context menu option for pin.
- Prevented user from connecting pins on same filter.
- Allowed input pins to be variants.
- Added pin connection and disconnection notification.
- Added 'Tee' filter.
- Added 'CastType' filter.
In CzGraph and CzFilter
- When connecting pins, check for circular input dependencies (looking upstream for self).

v2.7.3.3

Included with L3DT Professional v2.7 build 14.
In ZeoGraphWnd:
- Automatically loads 'Default.zgraph' filter the first time ZeoGraph is loaded.
- Added 'Help→User guide (on-line)' menu item.
- Set enable state of options/disconnect/etc menu items.
- Added toolbar (new/load/save/new filter/run/stop/disconnect/options/etc.)
- Fixed run/stop toolbar button state.
- Added blue highlight rect around topmost filter.
In FilterTreeDlg:
- Counts filters in each namespace, and appended to namespace label in tree (e.g. 'Generate (5)').
Filters:
- Modified 'project.SetProjectMap' to force refresh of map in view (optional, with flag).
- Renamed 'PerlinEx' filter to 'Perlin2' for consistency and future-proofing.
- Ensured all filter options pages say 'filter options' (not 'properties').
- Implemented 'stop graph' feature in threaded build.
All:
- Test behaviour when filters fail, or when rendering is cancelled.
- Fixed error reporting in filter & graph functions (couldn't show log view from worker thread).

v2.7.3

Implemented CzGraph, CzFilter, CzPin and CzFilterFactory as portable classes that may be used in other plugins.
Implemented graph load/save in CzGraph.
Associate 'zgraph' extension with L3DT in installer, and handled in command line processor.
Added progress display to 'CopyMapArea' function (In L3DT) so that filters such as GetProjectMap have a display whilst they are copying large maps.
In FilterTreeDlg:
- Implement filter picker tree dialog, for nested tree namespaces.
In ZeoGraphWnd:
- Added text overlay on mouse hover over pins, and render their current value.
- Implement double-buffered rendering (all rendering funcs take CDC arg, for portability).
- Made file open/save window default to graph directory in resources if no filename is set.
- Provided menu options for topmost filter in dropmenu.
- Saved and restored window size using GetWndSetting/SetWndSetting.
- Set title from file name.
- Re-sorted filters for z-ordering.
- Changed connection rendering to handle filter z-ordering.
- Add visual queue to indicate filter has editable options.
- Truncate filter names to remove namespaces.
- Show topmost filter in different scheme.
