0.12.1.0

  • Now compatible with GHC 7.9

  • Reintroduced the Chunk class, used by the parsers package

0.12.0.0

  • A new internal representation makes almost all real-world parsers faster, sometimes by big margins. For example, parsing JSON data with aeson is now up to 70% faster. These performance improvements also come with reduced memory consumption and some new capabilities.

  • The new match combinator gives both the result of a parse and the input that it matched.

  • The test suite has doubled in size. This made it possible to switch to the new internal representation with a decent degree of confidence that everything was more or less working.

  • The benchmark suite now contains a small family of benchmarks taken from real-world uses of attoparsec.

  • A few types that ought to have been private now are.

  • A few obsolete modules and functions have been marked as deprecated. They will be removed from the next major release.

0.11.3.0

  • New function scientific is compatible with rational, but parses integers more efficiently (https://github.com/bos/aeson/issues/198)

0.11.2.0

  • The new Chunk typeclass allows for some code sharing with Ed Kmett's parsers package: http://hackage.haskell.org/package/parsers

  • New function runScanner generalises scan to return the final state of the scanner as well as the input consumed.

0.11.1.0

  • New dependency: the scientific package. This allows us to parse numbers much more efficiently.

  • peekWord8', peekChar': new primitive parsers that allow single-character lookahead.
