## 5.1.0 (2017-10-12)
### Enhancements
* Suport string attributes as parameter attributes
* Support more calling conventions
* Support `NoTail` `TailCallKind`
## 5.0.0 (2017-09-07)
* Support for LLVM 5.0
We only give a summary of the changes affecting the public API of `llvm-hs-pure` here.
Please refer to the official
[release notes for LLVM 5.0](http://releases.llvm.org/5.0.0/docs/ReleaseNotes.html)
for an overview of all changes in LLVM 5.0.
* The `X86_64_Win64` calling convention is now called `Win64`.
* There is a new `Speculatable` function attribute.
* The `CrossThread` synchronization scope has been removed. There is
now a new `System` synchronization scope.
## 4.1.0 (2017-05-17)
* Switch AST to `ByteString`/`ShortByteString` reflecting LLVM’s use
of C-style strings.
* `preferredAlignment` is now a `Word32` instead of `Maybe Word32`. To
recover the old behavior set it to the same value as abiAlignment.
* `GlobalAlias` now expects the element type of a pointer type instead
of the pointer type itself. The address space is passed separately
via the `addrSpace` field. This makes `GlobalAlias` consistent with
`GlobalVariable`.
* The `FloatingPointType` constructor now takes a `FloatingPointType` argument
instead of a width and a `FloatingPointFormat` to more closely match the
LLVM IR language reference.
* The `IsString` instance of `Name` now throws an error on non-ASCII
strings instead of silently discarding the upper bytes. There is
also a new `mkName` function with the same behavior for easier
discoverability. Non-ASCII names need to be encoded using an arbitrary encoding to
to a `ShortByteString` which can then be used as a `Name`.
## 4.0.0 (initial release, changes in comparison to llvm-general)
* Move modules from `LLVM.General*` to `LLVM.*`
* Support for LLVM 4.0
* Improved support for LLVM’s exception handling instructions
* `-fshared-llvm` is now supported on windows (thanks to @RyanGLScott)
* Default to `-fshared-llvm`
* Expose `LLVM.Internal.*` modules.
