## [next]
## [1.3.0.0] - 2020-08-26
### 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
* Instances of `Elt` are now derivable via `Generic`
* 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) `EltRepr` is now a class-associated type of `Elt`
* (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])

### Added
* Pattern synonyms for manipulating custom product types can now be created;
see `Pattern`
* Probably many others I have forgotten about

### Removed
* Drop support for GHC-7.10
* Drop support for GHC-7.10 .. 8.4.
