Before the upgrade

Nothing.

After the upgrade

From zora.4 the syntax is unchanged. From athena.1, zora.3 and older, the upgrade copies the planning annotations unchanged; change them by hand. The build reports each one, fix them topmost error first.

• Each entry of a planning rows list (the rows of a window and children) is a group that holds the rows and, optionally, the selected items commands. Wrap the rows in ( 'rows' = ... ). The build reports an entry that is not wrapped with no valid 'nodes' found for 'type' option 'nodes'. Unexpected 'strategy', defined by .'planning row group':

// old
'rows' = [
	on .'rows'* (
		'label' = [ .'key' ( ) ]
	)
]

// new
'rows' = [
	( 'rows' = on .'rows'* (
		'label' = [ .'key' ( ) ]
	) )
]

• In draggable, move becomes drop on row and alternative move command becomes alternative drop on row. In a drop on row command, can switch row becomes row scope: 'yes'.'<row>' becomes 'reference'.'<row>'; drop 'can switch row' = 'no', as 'self' is the default. The build reports the old names with entry `move` was not found in 'properties' and entry `can switch row` was not found in 'properties':

// old
'draggable' = (
	'move' = .'move' (
		'start' = .'start' ( )
		'can switch row' = 'yes'.'row' ( )
		'snap' = 'minute' 60
	)
)

// new
'draggable' = (
	'drop on row' = .'move' (
		'start' = .'start' ( )
		'row scope' = 'reference'.'row' ( )
		'snap' = 'minute' 60
	)
)

• A planning popup shows its properties in columns: its node moves into 'columns' = ( 'node' = ... ) and its label is removed; a column can take a 'header' instead. The build reports the old popup with entry `label` was not found in 'properties' and entry `node` was not found in 'properties':

// old
'popup' = (
	'label' = [ .'key' ( ) ]
	'node' = [ 'text' .'key' ( ) ]
)

// new
'popup' = (
	'columns' = ( 'node' = [ 'text' .'key' ( ) ] )
)
