0.11.1

Added

• Segmented scans are a good bit faster.

• reduce_by_index has received a new implementation that uses
  local memory, and is now often a good bit faster when the target
  array is not too large.

• The f32 and f64 modules now contain gamma and lgamma
  functions. At present these do not work in the C# backend.

• Some instances of reduce with vectorised operators (e.g. map2 (+)) are orders of magnitude faster than before.

• Memory usage is now lower on some programs (specifically the ones
  that have large maps with internal intermediate arrays).

Removed

• Size parameters (not annotations) are no longer permitted
  directly in let and loop bindings, nor in lambdas. You are
  likely not affected (except for the stream constructs; see
  below). Few people used this.

Changed

• The array creation functions exported by generated C code now take
  int64_t arguments for the shape, rather than int. This is in
  line with what the shape functions return.

• The types for stream_map, stream_map_per, stream_red, and
  stream_red_per have been changed, such that the chunk function
  now takes the chunk size as the first argument.

Fixed

• Fixes to reading values under Python 3.

• The type of a variable can now be deduced from its use as a size
  annotation.

• The code generated by the C-based backends is now also compilable
  as C++.

• Fix memory corruption bug that would occur on very large segmented
  reductions (large segments, and many of them).
