  Thanks to Sean Leather for the report.

• Clean up some compiler warnings.

Version 0.3: 24 August 2011

• New permutation- and set-binding functions, for creating binders which don't care about the order of multiple bound names, and/or about unused bound names.

• Bump RepLib dependency to 0.5, which now has support for GADTs without existential type variables.

Version 0.3.1: 25 August 2011

• Update to build on GHC 7.2.1

Version 0.4: 15 March 2012

• Update to build on GHC 7.4.1

• add MonadWriter instances for FreshMT and LFreshMT

• Make 'getAvoids' function into a method of the LFresh class

Version 0.4.0.1: 23 March 2012

• Remove broken links from documentation

Version 0.4.0.2: 10 April 2012

• Bump 'mtl' upper bound to allow mtl-2.1

Version 0.4.1: 5 June 2012

• Patch from Vilhelm Sjöberg changing acompareR1 to return EQ for Abstract1

Version 0.4.1.1: 21 Aug 2012

• Bump containers upper bound and test with GHC 7.6.1

Version 0.4.2: 15 July 2013

• remove derived instances: MonadState for FreshMT and MonadReader for LFreshMT. No one should have been using these anyway, and they made it impossible to use these transformers together with your own state.

• added unbind variants [l]unbind{23}Plus for conveniently unbinding in a MonadPlus context.

Version 0.4.3: 29 January 2014

• Add Binary instances for Name, GenBind, Rebind, and Embed.

  Note that although the PVP requires a major version bump for added instances, it was impossible to write these instances outside of the package, so there is no danger of breakage.

Version 0.4.3.1: 8 May 2014

• Allow transformers-0.4 and mtl-2.2

Version 0.4.4: 18 May 2015

• Update to work with GHC 7.10

Version 0.4.5: 2 Oct 2015

• Test suite in cabal file
• New optimized function for immediately substitution w/o naming Only works for patterns with a single variable: substBind :: Subst a b => Bind (Name a) b -> a -> b

Version 0.5: August 2016

• Remove Show superclass for Alpha (potentially breaking change)

• Remove permValid function from Unbound.PermM

• New function in Unbound.LocallyNameless.Ops patUnbind :: (Alpha p, Alpha t) => p -> Bind p t -> t

• More sensible Show instance for bind, shows as code that can be directly parsed to Haskell. old: (Var 0@0) new: (bind (string2Name "a") (Var (string2Name "a"))

• works with GHC-8.0.1

• Error message if don't override aeq' / acompare' for abstract types

• More correctness tests
