+0.5.0.0
+=======
+
+* Switch to using the builder provided by the `ByteString` package
+* Change the encoding of Float and Double with the Serialize class to use the
+  `Data.Serialize.IEEE754` module
+* Add support for encoding and decoding `ShortByteString`
+* New and improved test suite thanks to Kei Hibino
+* Fix two bugs involving the `lookAhead` combinator and partial chunks.

--- | A 'Builder' is an efficient way to build lazy 'L.ByteString's.
--- There are several functions for constructing 'Builder's, but only one
--- to inspect them: to extract any data, you have to turn them into lazy
--- 'L.ByteString's using 'toLazyByteString'.
---
--- Internally, a 'Builder' constructs a lazy 'L.Bytestring' by filling byte
--- arrays piece by piece.  As each buffer is filled, it is \'popped\'
--- off, to become a new chunk of the resulting lazy 'L.ByteString'.
--- All this is hidden from the user of the 'Builder'.
