<h3>Changes in polyparse-1.2</h3>
<p>
<ul>
<li>Improves the Text.Parse implementation significantly.  Where
    previously all the parsers for builtin basic datatype (Int,Float,Char)
    were just thin wrappers over the H'98 Read instances, now they are all
    proper parsers, therefore they should (a) be faster; (b) give better
    error messages.
<li>Reduced the number of implementation variations to choose from.
    In particular, NoLeak has become the default implementation, and
    the previous default has been dropped (because it space-leaks).
<!--
<li>[desired] The class interface providing common operations across all
    implementations, now need be no slower than the previous
    cut-n-pasted interface, due to compiler specialisation of all the
    instances.
<li>[desired] New combinators for parsing infix structures, with
    associativity and precedence information.
<li>[desired] Multiple layers of bracketing can be parsed in linear time,
    rather than the previous exponential solution.
-->
</ul>

<h3>Changes in polyparse-1.1</h3>
<p>
<ul>
<li>Much improved the laziness of the PolyLazy combinators.
<li>Addition of a class-based interface to the Poly libraries, to
    reduce code duplication amongst the variations, and to allow for
    more experimentation with different implementations.
<li>Several new experimental implementations of the interface.
</ul>

<h3>Changes in polyparse-1.0</h3>
<p>
<ul>
<li>Version number change from 1.00 to 1.0, for silly cabal/hackage.
<li>Minor fix to parsing strings in Text.Parse.
</ul>

<h3>Changes in polyparse-1.00</h3>
<p>
<ul>
<li>No changes, but released separately from HaXml
</ul>

<h3>Changes in HaXml-1.16</h3>
<p>
<ul>
<li> New: lazier parsers
     <ul>
     <li> <tt>Text.XML.HaXml.ParseLazy</tt>
     <li> <tt>Text.XML.HaXml.Html.ParseLazy</tt>
     <li> <tt>Text.ParserCombinators.PolyLazy</tt>
     <li> <tt>Text.ParserCombinators.PolyStateLazy</tt>
     </ul>
</ul>

<h3>Changes in HaXml-1.15</h3>
<p>
<ul>
<li> New: DrIFT has now been fully updated to
     produce instances of Text.ParserCombinators.TextParser.Parse.
<li> New: the parser combinator library Poly has been split into two
     variations, Poly and PolyState.  They have almost the same API,
     only the latter includes a running state where the former does not.
<li> The TextParser library (a replacement for the Haskell'98 Read class)
     has also been improved with more new combinators.  Really, these
     parser combinator experiments do not belong in HaXml, and will
     eventually be split out into a separate package.
</ul>
