+A new flexible template suitable for a range of choral music, is now
+provided. This may be used to create simple choral music, with or
+without piano accompaniment, in two or four staves. Unlike other
+templates, this template is @q{built-in}, which means it does not
+need to be copied and edited: instead it is simply @code{\include}'d
+in the input file. For details, see @rlearning{Built-in templates}.

+The positioning of tuplet numbers for kneed beams has been significantly
+improved. Previously, tuplet numbers were placed according to the
+position of the tuplet bracket, even if it was not printed. This could
+lead to stranded tuplet numbers. Now they are now positioned
+closer to the kneed-beam when an appropriate beam segment exists for its
+placement and when the bracket is not drawn.
+
+Collision detection is also added, offsetting horizontally if too close
+to an adjoining note column but preserving the number's vertical
+distance from the kneed beam. If the number itself is too large to
+fit in the available space the original, bracket-based, positioning
+system is used instead; and in the event of a collision (e.g. with an
+accidental) the tuplet number is moved vertically away instead.
