Dates
In addition to changes in the programmatic interface, the 2.0 version has
extensive changes in the user interface.
In system software version 1.x, the Dates application allowed notes (text and
graphics) to be written without an associated meeting marker. In system
software 2.0, such notes, previously called annotations, cannot be written.
Annotations imported via Newton Connection Kit from a 1.x system are still
visible and editable, however. As in version 1.x, these objects are stored in the
ROM_CalendarSoupName
soup.
In 1.x versions, all instances of a repeating meeting or repeating events share the
same set of notes. A repeating meeting is one that recurs at a periodic time
interval. In 2.0, notes of a repeating meeting and repeating events are local to
each occurrence of the meeting. When a 1.x repeating meeting is converted to
2.0 format, all the notes are typically added to the meeting instance whose
meeting slip the user opens first.
