accelerate v1.3.0.0 Release Notes

Release Date: 2020-08-26 // over 3 years ago

➕ Added
- Instances of Elt are now derivable via Generic for simple (Haskell'98) product and sum data types.
- Pattern synonyms for manipulating custom product and sum types can now be created; see Pattern, mkPattern
- Added pattern synonyms for accessing tuples and indices, as an alternative to lift and unlift.
- Support for pattern matching in the embedded language; see match
🔄 Changed
- The stencil functions now support fusion. Note however that the source (delayed) array will be evaluated at every access to the stencil pattern; if the delayed function is expensive, you may wish to explicitly compute the source array first, matching the old behaviour.
- Removed Slice constraint from some indexing operations
- Improve fusion for zipWith* ([#453])
- The indexing function to permute now returns a Maybe type ([#87])
- (internal) Visible type applications are used instead of Proxy types
- (internal) EltR is now a class-associated type of Elt
- (internal) GArrayData has been simplified
- (internal) SIMD representation has been improved and generalised
- (internal) Internal refactoring ([#449], [#455], [#457], [#460])
- Probably many others I have forgotten about
✂ Removed
- Drop support for GHC-7.10 .. 8.4.
