# Release history for fudgets

## 0.19.0 --  2026-??-??

* You can now cabal configure with the flag ``-fx11protocol``
  to use a new [X Windows System Protocol](https://www.x.org/releases/current/doc/xproto/x11protocol.html) implementation instead of the old
  home-grown binding to the Xlib C library, eliminating most uses of
  the Foreign Function Interface and the potential memory safety issues
  what come with it.

  The X Window System Protocol implementation is still work in progress,
  but all the demos and examples listed in ``fudgets.cabal`` work, and so
  do some larger programs, like WWWBrowser and Alfa.

  Known issues: dependencies on
  [network](https://hackage.haskell.org/package/network)<2.7 and
  [select](https://hackage.haskell.org/package/select)
  can cause problems:
  
  * ``network-2.6.3.6`` can be installed with recent versions of ghc
  by using ``--allow-newer``.
  * ``select`` contains a superfluous ``extra-libraries: rt``. It
    appears to be harmless on Linux, but needs to be removed on macOS.

* The fudget ``bufferButtonF`` was added to ``ContribFudgets``.

* Changes to data types (requiring a major version number bumb, even though
  the changes are fairly small):

  * Added support for the GC attribute ``GCArcMode``, with choices
	``ArcChord`` and (the default) ``ArcPieSlice``.
  
  * The data type ``Points`` was added and used in the constructors
	``DrawLines`` and ``FillPolygon`` in the ``DrawCommand`` data type.
	Backwards compatible functions ``drawLines`` and ``fillPolygon``
	were also added.

  * The data type ``BitmapData`` was added and used in the
	``BitmapReturn`` data type.

* Various minor documentation improvements, bug fixes, internal
  implementation changes and source code cleanup. Fixed some old-style
  C function declarations.

* Tested with 20 different versions of GHC, from 7.4.1 to 9.14.1.

## 0.18.4 --  2023-06-27

* ``Cla`` (Lennart Augustsson's calculator) is now included.

* Added support for binary I/O with lazy bytestrings to files and network
  sockets.

* Removed the last remnants of the ``PackedString`` type.

* Tested with 14 different versions of GHC, from 7.4.1 to 9.6.2.

* Fudgets turned 30 this month, can you believe it?
  [The first paper on Fudgets](https://www.altocumulus.org/Fudgets/fpca93-abstract.html)
  was presented at the *Conference on Functional Programming Languages and
  Computer Architecture*, Copenhagen, June 1993.

## 0.18.3.2 --  2022-08-04

* Simplified the installation on macOS by adding a helper script
  `hsrc/fudcpp` to workaround problems with the `-optP`  option in
  `ghc>=8.10.3` and automatically detect which version of `gcc` is installed.
  
## 0.18.3.1 -- 2022-03-14

* Renamed `doRequest.hs` to `doRequestCmd.hs` to avoid a name clash
  with `DoRequest.hs` on systems with case-insensitive file names.

## 0.18.3 -- 2022-03-13

* Although Fudgets dates back to the early 1990s, this is the first
  release on Hackage.
