Version 0.9

• BACKWARDS COMPATIBLE COMPILER ASSISTED CHANGE: The Show, Read, Eq, Ord and Generic instances now live in the exinst-base package. This is so that exinst doesn’t need to depend on the large singletons-base. Users wanting access to those instances need to import Exinst.Base explicitly.

• Builds with GHC 9.4.

• The tests for exinst now live in exinst-base.

Version 0.8

• Builds with GHC 8.10 and singletons-2.7.

Version 0.7

• BACKWARDS COMPATIBLE COMPILER ASSISTED CHANGE: All of the cabal flags for turning on and off instances were removed. The hashable are now always exported from the exinst, and the aeson, bytes, cereal and serialise instances are now exported from new packages exinst-aeson, exinst-bytes, exinst-cereal and exinst-serialise. The instances exported from those packages are the same as the ones exported with exinst-0.6.

Version 0.6

• The binary and deepseq Cabal flags were removed since these two packages are always included with the GHC distribution, so it doesn’t make sense to make them optional.

• The optional dependencies hidden behind Cabal flags now apply to the test suite as well.

• Builds with GHC 8.4.

Version 0.5

• BREAKING: Depend on singletons == 2.3.*.

• Add same{1,2,3,4}.

• Add dependencies on cborg and serialise

• Add instances for serialise (binary CBOR encoding/decoding)

Version 0.4

• BREAKING: Decouple binary and cereal instances from bytes. This introduces a slight backwards incompatible change if you were using some Serial instances that depended on host endianness (such as Int).

• Add P1, P2, P3, P4.

• Add S1, S2, S3, S4.

• Add Read instances for Some{1,2,3,4}.

• Moved documentation from README.md into the top-level Exinst module.

Version 0.3.0.1

• Removed dependency on generic-random.

• Correctly deal with cabal flags for deepseq and hashable.

• Add binary’s Data.Binary.Binary and cereal’s Data.Serialize.Serialize instances for Some{1,2,3,4}. These instances are compatible with each other and rely on the Data.Bytes.Serial instances.

Version 0.3

• BREAKING: Renamed module Exinst.Singletons to Exinst.

• BREAKING: The Exinst.Instances.Base module is gone. The base instances are now exported from Exinst.

• Add Dict0.

• Re-export Constraint from base.

• Add Dict{0,2,3,4} instances for Bool.

• Add GHC.Generics.Generic support for Some{1,2,3,4}. This only works for indexes with PEnum and PBounded instances.

• Added tests.

• Added Test.QuickCheck.Arbitrary instances for Some{1,2,3,4} in Exinst.Instances.QuickCheck. These instances and their dependency on QuickCheck can be toggled with the quickcheck Cabal flag.

• Added Data.Aeson.{FromJSON,ToJSON} instances for Some{1,2,3,4} in Exinst.Instances.Aeson. These instances and their dependency on aeson can be toggled with the aeson Cabal flag. These instances used to exist in now-deprecated the exinst-aeson package, and are compatible with them.

• Added Bytes.Serial.Serial instances for Some{1,2,3,4} in Exinst.Instances.Bytes. These instances and their dependency on bytes can be toggled with the bytes Cabal flag. These instances used to exist in now-deprecated the exinst-bytes package, and are compatible with them.

• Added Control.DeepSeq.NFData instances for Some{1,2,3,4} in Exinst.Instances.DeepSeq. These instances and their dependency on deepseq can be toggled with the deepseq Cabal flag. These instances used to exist in now-deprecated the exinst-deepseq package, and are compatible with them.

• Added Data.Hashable.Hashable instances for Some{1,2,3,4} in Exinst.Instances.DeepSeq. These instances and their dependency on hashable can be toggled with the hashable Cabal flag. These instances used to exist in now-deprecated the exinst-hashable package, and are compatible with them.

Version 0.2

• Depend on singletons-2.2, which means KProxy is gone.

• Add _Some{1,2,3,4} prisms.

• Add Dict1 instance for Bool.

• Add some{1,2,3,4}SingRep.

• Thanks to Sandy Maguire for having contributed to this release.

Version 0.1.2

• Export the Some{1,2,3,4} constructors.

• Make all the fields in Some{1,2,3,4} strict.

• Relax upper bound on base, singletons, constraints.

• Re-export Dict(Dict) from constraints.

Version 0.1.1

• Relax upper bound on singletons dependency.

• withSome{1,2,3,4}Sing brings SingI instances to scope.

• Generalized the (* -> Constraint) parameter in Dict{1,2,3,4} to (k -> Constraint).

Version 0.1

• Initial release.
