Changelog of @hackage/haddock 2.2.2

Changed in version 2.2.2:

Changes in version 2.2.1:

Support for GHC 6.8.3
The Hoogle backend is back, thanks to Neil Mitchell. The plan is to be compatible with the upcoming Hoogle 4 pre-release
Show associated types in the documentation for class declarations
Show type family declarations
Show type equality predicates
Major bug fixes (#1 and #44)
It is no longer required to specify the path to GHC's lib dir
Remove unnecessary parenthesis in type signatures

Changes in version 2.1.0:

Fix a bug that made links point to the defining module instead of the "best" one (e.g Int pointing to GHC.Base instead of Data.Int)
Fix a couple of smaller bugs
The representation of DocName was changed in the library
Add a flag --no-warnings for turning off warnings

Changes in version 2.0.0.0:

The GHC API is used as the front-end
Haddock now understands all syntax understood by GHC 6.8.2
Haddock can generate documentation for some of the language extensions in GHC 6.8.2
Format of module attributes has changed. The only way of specifiying module attributes is via a new OPTIONS_HADDOCK pragma. Example: {-# OPTIONS_HADDOCK hide, prune #-}
Haddock understands literate source files
Add a small library to read Haddock's interface files
Add a flag -B for passing the path to the GHC lib dir
Add a flag --optghc for passing options to GHC
Add a flag --ghc-version for printing the GHC version
Remove --use-package, --allow-missing-html, --ghc-pkg, in favour of only supporting --read-interface
Remove --package flag, the GHC flag -package-name can be used instead
Remove --no-implicit-prelude flag, the GHC flag -XNoImplicitPrelude can be used instead

Changes in version 0.9:

Infix type operators, e.g., first :: a~>a' -> (a,b)~>(a',b)
Add a search box to the index page which automatically narrows the index to the search as you type (thanks to Neil Mitchell).
Add a --ghc-pkg flag
Add a flag --allow-missing-html
URL expansion for %%, %L, %{LINE}
added substitution %{FILE///c}
Lexing of /.../ is now more like '...', in that a / character must be matched by another / character on the same line, otherwise it is treated as a literal '/'. This removes a common source of accidental parse errors in documentation.
Various bugs were fixed.
Cabal 1.2 is now required, and Haddock builds with GHC 6.8.x.

Changes in version 0.8:

Haddock has a Cabal build system, and will build on Windows without Cygwin or MSYS. GHC 6.4 or later is required.
New options: --comments-base, --comments-module, --comments-entity for generating links to pages (eg. wiki) for collecting user comments.
New options: --source-base, --source-module, --source-entity for generating links to source code. Haddock now understands {-# LINE #-} pragmas, which means it can figure out the correct name for the source file even if the file is preprocessed.
Haddock generates output for populating the Hoogle search engine.
New markup <> for including images.

Changes in version 0.7:

Changes in the way Haddock decides where to direct hyperlinks. Each entity is now assigned a single "home" module, and all hyperlinks are directed to that module. See the docs ("Hyperlinking and re-exported entities") for details.
New options --ignore-all-exports, --hide
New option --use-package for creating documentation that hyperlinks to the HTML documentation for existing packages on your system. It works by querying ghc-pkg for the location of the Haddock interface and HTML for the given package.
Parts of the HTML documentation, notably lists of instances, are now "collapsible" with a +/- button. Also, the contents page is now in the form of tree in which subtrees can be collapsed.
Support for Microsoft DevHelp and HtmlHelp 2.0 formats.
Support for a short description for each module for the contents page.
Compiles with GHC 6.4+
Various bugfixes

Changes in version 0.6:

Implicit parameters, zip comprehensions and 'mdo' are now supported by the parser.
Some lexical bugs were fixed, mainly concerning literal paragraphs next to non-literal paragraphs.
New options: --gen-index, --use-index, --gen-contents and --use-contents, for generting a combined index and contents for several libraries from the appropriate .haddock files.
There is now one index rather than separate Function/Constructor and Type/Class indices. Where a name refers to several entities, these are listed separately in the index.
New option: -v, elicits more verbose warnings. Some warnings are now turned off by default; Haddock should be a little less noisy in general.
Markup for definition lists has been added. See the documentation for details.
New option: --package for setting the package name. The package is listed alongside each module name in the combined contents.
Entities which are re-exported from another package now at least leave a hyperlink in the generated HTML, rather than nothing at all.
Some fixes for bugs which caused incorrect hyperlinks in the generated HTML. In particular, instances should now be linked correctly.
Some aesthetic improvements to the generated HTML.

Changes in version 0.5:

Changes in version 0.4:

Import declarations which list entities in parentheses, or with hiding clauses, are now properly supported. Modulo one or two small infelicities, the full Haskell modules system is now supported.
Haddock is now more flexible about the placing of separators (commas, semicolons) in relation to doc comments.
There is support for generating and reading "interface files" which describe the exports of a set of modules. This is useful for generating documentation which hyperlinks to previously-generated documentation.
Support for generating the extra files required by the Microsoft Help compiler.
New option: --prologue specifies a file of documentation which is placed on the contents page.
Many bugs fixed

Changes in version 0.3:

Documentation on individual function arguments is now implemented
Links can be made to identifiers that aren't in scope, by using the fully qualified name.
Instances are collected and listed with the appropriate classes and datatypes (not for derived instances yet).
Single quotes are only interpreted specially when they surround a legal Haskell identifier, otherwise they are treated literally.
Bird-tracked text is now literal. If you want marked-up text in a code block, use the @...@ notation instead.
Various changes to the layout, it generally looks nicer now.
Various bugs fixed.
