fixed 2 segfaults: one when trying to delete array that is being read/written to by a dsp process (e.g. tabwrite), and another where creating undo checkpoint when deleting array would generate bogus data that would crash pd-l2ork. Currently undoing array deletion is not supported by undo.

experimental implementation of disabling drawing outside the GOP array boundaries (currently disabled)

fixed regression due to idiotic way how arrays and scalars are allowed to spill outside its GOP frame...

fixed bug where curve parameter was ignored when entering value pairs (target duration) without the curve parameter

refined multiconnect's 3rd option and code comments for 2nd and 3rd option to reflect use with only 2 objects selected

added local version of the docs due to increasing number of local changes that make it difficult to sync with external

added preset_node_array abstraction and supporting help files (plus improvements to preset_node and preset_hub)

fixed elusive problem with undo where actions did not behave properly because of failing to update canvas_undo_name

all gop widgets (at least ones in vanilla release) have their nlets hidden when displayed inside GOP, as having them is entirely superfluous in that view

fixed image external to conform with the new implementation of @pd_extra (and later other possible sys args) of the file path parser

streamlined @pd_extra parsing for easier integration with other file open calls including externals. Added it to open_via_path
