# Changelog for the [`clash-lib`](http://hackage.haskell.org/package/clash-lib) package

## 0.5.7 *June 25th 2015*
* New features:
  * Support for copying string literals from Haskell to generated code
  * Collect and copy data-files

* Fixes bugs:
  * Signals declared twice when not using a clock-generating component [#60](https://github.com/clash-lang/clash-compiler/issues/60)
  * This piece of code eat up all CPU when generating verilog [#62](https://github.com/clash-lang/clash-compiler/issues/60)

## 0.5.6 *June 3rd 2015*
* New features:
  * Support Verilog backend
  * Generated component names are prefixed by the name of the module containing the `topEntity`

## 0.5.5 *May 18th 2015*
* New features:
  * Make inlining and specialisation limit configurable
  * Make debug message level configurable

* Fixes bugs:
  * Netlist: ensure that the arguments of a component instantiation are always simple variables
  * CaseCon transformation: ensure that we run the compile-time evaluator on the subject before handling the one-alternative case
  * Emit a warning if a function remains recursive, instead of producing an error: compilation can still be successful if the function is an argument to a higher-order blackbox that doesn't use the function.
  * Emit a warning if inlining limit is reached, instead of producing an error: compilation can still be successful if the function is an argument to a higher-order blackbox that doesn't use the function.
  * Always inline terms that have a type of kind `Constraint`

## 0.5.4 *May 10th 2015*
* New features:
  * Add `~COMPNAME` tag: primitives get access to the component name in which they are instantiated

## 0.5.3 *May 5th 2015*
* New features:
  * `TopEntity` wrappers are now specified as `ANN` annotation pragmas
* Fixes bugs:
  * Lost system1000 clock in VHDL generation... [#53](https://github.com/clash-lang/clash-compiler/issues/53)
  * `flattenCallTree` sometimes introduces free variables

## 0.5.2 *May 1st 2015*
* New features:
  * Generate wrappers around `topEntity` that have constant names and types

## 0.5.1 *April 20th 2015*
* GHC 7.10 support

## 0.5 *March 11th 2015*
* New features:

  * Use unbound-generics. [#48](https://github.com/clash-lang/clash-compiler/issues/48)

* Fixes bugs:
  * VHDL generation error: wrapper for sum-of-products type. [#44](https://github.com/clash-lang/clash-compiler/issues/44)

## 0.4.1 *February 4th 2015*
