ChangeLog

0.7.7

• Test now compiles with smallcheck >= 1.2 and base >= 4.14. See #153.

0.7.6

• Now only depends on fail / semigroups shim for ghc < 8.

0.7.4

• Fix for compilation with ghc-8.10 in 0.7.3 did not use enough CPP, and so broke builds for older versions. This release fixes that.

0.7.3

• Fixes compilation with ghc-8.10, particularly template-haskell-2.16.0.0. See #149.

0.7.2

• Fixes compilation with vector >= 0.12.1.1 by making deriveManyStoreUnboxVector capable of handling more complex instance constraints. In particular, it now correctly generates instances Store (Vector (f (g a))) => Store (Vector (Compose f g a)) and Store (Vector (f a)) => Store (Vector (Alt f a)).

0.7.1

• Fixes compilation with GHC-7.10 due to it not defining Generic instances for Complex and Identity. See #142.

• Documents some gotchas about using store vs other libraries

0.7.0

• Fixes a bug where the Store instances for Identity, Const, and Complex all have Storable superclasses instead of `Store. See #143.

0.6.1

• Can now optionally be built with integer-simple instead of integer-gmp, via the integer-simple cabal flag. Note that the serialization of Integer with integer-simple differs from what is used by the GMP default. See #147.

0.6.0.1

• Now builds with GHC-7.10 - compatibility was broken in 0.6.0 due to the fix for GHC-8.8. See [#146][https://github.com/fpco/store/issues/146].

0.6.0

• Now builds with GHC-8.8. This is a major version bump because MonadFail constraints were added to some functions, which is potentially a breaking change.

0.5.1.2

• Fixes compilation with GHC < 8.0. See #142.

0.5.1.1

• Update to the instances for generics, to improve error messages for sum types with more than 255 constructors. See #141

0.5.1.0

• Update to TH to support sum types with more than 62 constructors.

• Uses TH to derive Either instance, so that it can sometimes have ConstSize #119.

0.5.0.1

• Updates to test-suite enabling store to build with newer dependencies.

0.5.0

• Data.Store.Streaming moved to a separate package, store-streaming.

0.4.3.2

• Buildable with GHC 8.2

• Fix to haddock formatting of Data.Store.TH code example

0.4.3.1

• Fixed compilation on GHC 7.8

0.4.3

• Less aggressive inlining, resulting in faster compilation / simplifier not running out of ticks

0.4.2

• Fixed testsuite

0.4.1

• Breaking change in the encoding of Map / Set / IntMap / IntSet, to use ascending key order. Attempting to decode data written by prior versions of store (and vice versa) will almost always fail with a decent error message. If you're unlucky enough to have a collision in the data with a random Word32 magic number, then the error may not be so clear, or in extremely rare cases, successfully decode, yielding incorrect results. See #97 and #101.

• Performance improvement of the 'Peek' monad, by introducing more strictness. This required a change to the internal API.

• API and behavior of 'Data.Store.Version' changed. Previously, it would check the version tag after decoding the contents. It now also stores a magic Word32 tag at the beginning, so that it fails more gracefully when decoding input that lacks encoded version info.

0.4.0

Deprecated in favor of 0.4.1

0.3.1

• Fix to derivation of primitive vectors, only relevant when built with primitive-0.6.2.0 or later

• Removes INLINE pragmas on the generic default methods. This dramatically improves compilation time on recent GHC versions. See #91.

• Adds instance Contravariant Size

0.3

• Uses store-core-0.3.*, which has support for alignment sensitive architectures.

• Adds support for streaming decode from file descriptor, not supported on windows. As part of this addition, the API for "Data.Store.Streaming" has changed.

0.2.1.2

• Fixes a bug that could could result in attempting to malloc a negative number of bytes when reading corrupted data.

0.2.1.1

• Fixes a bug that could result in segfaults when reading corrupted data.

0.2.1.0

Release notes:

• Adds experimental Data.Store.Version and deprecates Data.Store.TypeHash. The new functionality is similar to TypeHash, but there are much fewer false positives of hashes changing.

Other enhancements:

• Now exports types related to generics

0.2.0.0

Release notes:

• Core functionality split into store-core package

Breaking changes:

• combineSize' renamed to combineSizeWith

• Streaming support now prefixes each Message with a magic number, intended to detect mis-alignment of data frames. This is worth the overhead, because otherwise serialization errors could be more catastrophic - interpretting some bytes as a length tag and attempting to consume many bytes from the source.

Other enhancements:

• weigh based allocations benchmark.

• Addition of Array / UArray instances

• Streaming support now has checks for over/undershooting buffer

Bug fixes:

0.1.0.0

• First public release
