## [1.1.0.1] - 2017-10-04
### Fixed
* fix for `runQ*` generating multiple declarations with the same name
## [1.1.0.0] - 2017-09-21
### Added
* support for GHC-8.2
* caching of compilation results ([accelerate-llvm#17])
* new runtime linker; this fixes the annoying "forkOS_entry: interrupted" error. Note that currently this only supports x86_64 macOS and linux
* support for ahead-of-time compilation (`runQ` and `runQAsync`)
### Changed
* generalise `run1*` to polyvariadic `runN*`
* programs run using all cores by default; the environment variable
`ACCELERATE_LLVM_NATIVE_THREADS` is used to set the number of worker threads
rather than `+RTS -N`
