Change Log

Notable changes to the project will be documented in this file.

The format is based on Keep a Changelog and the project adheres to the Haskell Package Versioning Policy (PVP)

1.1.0.0 - 2017-09-21

Added

• Additional EKG monitoring hooks (#340)
• Operations from RealFloat

Changed

• Changed type of scanl', scanr' to return an Acc tuple, rather than a tuple of Acc arrays.
• Specialised folds sum, product, minimum, maximum, and, or, any, all now reduce along the innermost dimension only, rather than reducing all elements. You can recover the old behaviour by first flatten-ing the input array.
• Add new stencil boundary condition function, to apply the given function to out-of-bounds indices.

Fixed

• #390: Wrong number of arguments in printf

0.11.0.0

• New Prelude-like functions zip*, unzip*, fill, enumFrom*, tail, init, drop, take, slit, gather*, scatter*, and shapeSize.
• New simplified AST (in package accelerate-backend-kit) for backend writers who want to avoid the complexities of the type-safe AST.
