* New features:
* Moore machine combinators
## 0.7.4 **May 5th 2015*
* New features:
* Add `TopEntity` annotations
## 0.7.3 *April 22nd 2015*
* New features:
* Add the vector functions: `zip3`, `unzip3`, and `zipWith3`
* Use version 0.2 of the [`ghc-typelits-natnormalise` package](http://hackage.haskell.org/package/ghc-typelits-natnormalise)
## 0.7.2 *April 20th 2015*
* New features:
* Support for GHC 7.10 => only works with GHC 7.10 and higher
* Use http://hackage.haskell.org/package/ghc-typelits-natnormalise typechecker plugin for better type-level natural number handling
## 0.7.1 *March 25th 2015*
* Fixes bugs:
* Fix laziness bug in Vector.(!!) and Vector.replace
## 0.7 *March 13th 2015*
* New features:
* Switch types of `bundle` and `bundle'`, and `unbundle` and `unbundle'`.
* Rename all explicitly clocked versions of Signal functions, to the primed
name of the implicitly clocked Signal functions. E.g. `cregister` is now
called `register'` (where the implicitly clocked function is callled `register`)
* Add new instances for `DSignal`
* Add experimental `antiDelay` function for `DSignal`
* Generalize lifted functions over Signals (e.g. (.==.))
* Fixes bugs:
* Faster versions of Vector.(!!) and Vector.replace
## 0.6.0.1 *November 17th 2014*
* Fixes bugs:
* Add missing 'CLaSH.Sized.BitVector' module to .cabal file.
## 0.6 *November 17th 2014*
* New features:
* Add `Fractional` instance for `Fixed` [#9](https://github.com/christiaanb/clash-prelude/issues/9)
* Make indexing/subscript of `Vec` ascending [#4](https://github.com/christiaanb/clash-prelude/issues/4)
* Add separate `BitVector` type, which has a descending index.
* Add bit indexing operators, including the index/subscript operator `(!)`.
* Add bit reduction operators: `reduceOr`, `reduceAnd`, `reduceOr`.
* Rename `BitVector` class to `BitPack` with `pack` and `unpack` class methods.
* Rename `Pack` class to `Bundle` with `bundle` and `unbundle` class methods.
* Strip all `Vec` functions from their `v` prefix, i.e. `vmap` -> `map`.
* Rename `Vec` indexing operator from `(!)` to `(!!)`.
* Combine `Add` and `Mult` class into `ExtendingNum` class.
* Add extend and truncate methods to the `Resize` class.
* Add `SaturatingNum` class with saturating numeric operators.
* Add multitude of lifted `Signal` operators, i.e. `(.==.) :: Eq a => Signal a -> Signal a -> Signal Bool`
* Add `CLaSH.Signal.Delayed` with functions and data types for delay-annotated signals to support safe synchronisation.
* Add `CLASH.Prelude.DataFlow` with functions and data types to create self-synchronising circuits based on data-flow principles.
* Fixes bugs:
* Remove deprecated 'Arrow' instance for and related functions for `Comp` [#5](https://github.com/christiaanb/clash-prelude/issues/5)
## 0.5.1 *June 5th 2014*
* New features:
* Add `Default` instance for `Vec` [#2](https://github.com/christiaanb/clash-prelude/issues/2)
* Instantiation for `blockRam` [#3](https://github.com/christiaanb/clash-prelude/issues/2)
* Fixes bugs:
* Fixed error on documentation of fLit in Fixed.hs [#6](https://github.com/christiaanb/clash-prelude/issues/6)
* Non-translatable `Enum` function interfere with `sassert` compilation [#7](https://github.com/christiaanb/clash-prelude/issues/7)
* Substituted the word 'list' into 'vector' in some places in the documentation. [#8](https://github.com/christiaanb/clash-prelude/issues/8)
* mark vselectI INLINEABLE [#10](https://github.com/christiaanb/clash-prelude/issues/10)
