0.13.2.1

• Improved performance of Data.Attoparsec.Text.asciiCI

0.13.2.0

• pure is now strict in Position

0.13.1.0

• runScanner now correctly returns the final state (https://github.com/bos/attoparsec/issues/105).
• Parser, ZeptoT, Buffer, and More now expose Semigroup instances.
• Parser, and ZeptoT now expose MonadFail instances.

0.13.0.2

• Restore the fast specialised character set implementation for Text
• Move testsuite from test-framework to tasty
• Performance optimization of takeWhile and takeWhile1

0.13.0.1

• Fixed a bug in the implementations of inClass and notInClass for Text (https://github.com/bos/attoparsec/issues/103)

0.13.0.0

• Made the parser type in the Zepto module a monad transformer (needed by aeson’s string unescaping parser).

0.12.1.6

• Fixed a case folding bug in the ByteString version of stringCI.

0.12.1.5

• Fixed an indexing bug in the new Text implementation of string, reported by Michel Boucey.

0.12.1.4

• Fixed a case where the string parser would consume an unnecessary amount of input before failing a match, when it could bail much earlier (https://github.com/bos/attoparsec/issues/97)

• Added more context to error messages (https://github.com/bos/attoparsec/pull/79)

0.12.1.3

• Fixed incorrect tracking of Text lengths (https://github.com/bos/attoparsec/issues/80)

0.12.1.2

• Fixed the incorrect tracking of capacity if the initial buffer was empty (https://github.com/bos/attoparsec/issues/75)

0.12.1.1

• Fixed a data corruption bug that occurred under some circumstances if a buffer grew after prompting for more input (https://github.com/bos/attoparsec/issues/74)

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.
