Summary of breaking changes for v0.5

[lehins]

New release is not too far along:

• Introduce LoadS that will only be able to load arrays sequentially. This way it will be visible at the type level in the majority of the functions how a delayed array will be loaded
• Construct will no longer have knowledge about computation strategies, but Load will:
  • Move setComp to Load
  • possibly create separate makeArrayS and makeArrayLinearS
• Add type synonyms Matrix and Vector (not really breaking change, but many use those names and could easily introduce a conflict)
• Move functions from Data.Massiv.Array.Stencil.Unsafe into Data.Massiv.Array.Unsafe
• Remove traverseAR, itraverseAR, traversePrimR and itraversePrimR
• Move all pure partial functions (eg. index') into a separate module: Data.Massiv.Array.Partial and document all possible exception the safe synonyms can throw.
• Source will now have unsafeLinearSlice. Implement uncons, unsnoc, tail, head, init and last with it
• Add take, drop :: Source r ix e => Int -> Array r ix e -> Array D Ix1 e (using unsafeLinearSlice)
• add stoList and sfromList, sfromListN
• Get rid of Show instance for Value. Export constructor from unsafe. Add Show and Eq in test suite as orphans
• Consider switching applyStencil and mapStencil to return DL array, with some helper functions still returning DW.
• rename withMArray to withMArray_, withMArrayS to withMArrayS_ and withMArrayST to withMArrayST_
• Add new functions that, just as createArray*, return an element, which is an artifact of computation:
  • withMArray :: Array r ix e -> (Scheduler m b -> MArray RealWorld r ix e -> m a) -> m ([b], Array r ix e)
  • withMArrayS :: Array r ix e -> (MArray (PrimState m) r ix e -> m a) -> m (a, Array r ix e)
  • withMArrayST :: Array r ix e -> (forall s . MArray s r ix e -> ST s a) -> (a, Array r ix e)
• Remove Comp from functions that ignore it:
  • createArrayS_, createArrayS, createArrayST, createArrayST_
  • unfoldrPrimM_, iunfoldrPrimM_, unfoldrPrimM, iunfoldrPrimM, unfoldlPrimM_, unfoldlPrimM_, unfoldlPrimM, iunfoldlPrimM (also for all above avoid filling new array, the all use new instead of unsafeNew)
• make Data.Massiv.Array.Manifest.Vector.Stream internal but exportable. Move to Data.Massiv.Vector.Stream
• Add castToBuilder

Most of these have been implemented and a new release is up on Hackage. Ones that have not will either go into the next major release or will not be implemented at all. Closing.
