0.99.12
 - pressing Alt or F10 under Windows no longer pauses the application.
 - API changes:
    - PTC classes have been made descendants of TInterfacedObject and are now
      accessed via interfaces. This simplifies memory management, because
      objects are now reference counted and automatically freed when they are
      no longer used. Unfortunately, this breaks existing code. However it's
      relatively easy to fix. See the files INTF-CHANGES-0.99.12.txt and
      INTF-CHANGES-FAQ-0.99.12.txt for details.

0.99.11
 - added ptcgraph - an implementation of FPC's BGI-compatible graph unit on top
   of PTCPas. It should work on all platforms, supported by PTCPas,  except for
   DOS (because it doesn't have threads)
 - VBE console improvements:
    - support for double buffering with video page flipping
    - console update synchronized with the vertical retrace
    - automatic fallback to windowed mode, if initializing LFB fails. This
      results in better compatibility with NTVDM and other environments that
      would otherwise require adding the 'disable lfb' option to ptcpas.cfg.
    - support VBE 3+ separate LFB and Windowed color masks for direct color
      modes. This might fix some wrong color bugs in LFB mode on some modern
      VBE 3+ video cards.
 - fixed a bug in the X11 event handling that caused unnecessary high CPU use
   while waiting for an event

0.99.10
 - fpc 2.4.0 support
 - Win64 DirectX support
 - X11 DGA 2.0 support
 - VBE 2+ LFB support. Enabled by default. Offers a great performance
   improvement, but may fail on buggy VGA BIOSes or buggy DOS virtual
   machines. If it causes problems, it can be disabled by adding
   'disable lfb' to ptcpas.cfg.
 - API changes:
    - in the hermes unit, THermesHandle was replaced with
      THermesConverterHandle, THermesClearerHandle and THermesPaletteHandle,
      which should be treated as opaque pointers, not integers. This only
      matters if you use unit hermes directly, and not ptc.
 - various bugfixes and code cleanup.

0.99.9
 - big endian support.
 - Win64 support (GDI only. DirectX not supported yet).

0.99.8
 - added support for Windows CE. Still in alpha stage. Tested on a Motorola
   MPx220 smartphone.
 - added support for fullscreen X11 using the Xrandr extension (previously
   only the XF86VidMode extension was supported). Also fullscreen X11 now works
   even when there aren't any mode switching X11 extensions available. A single
   fullscreen mode, which has the size of the entire desktop is offered in this
   case.
 - added a new simple windowed win32 GDI console, which is able to run even
   without any version of DirectX installed.
 - the X11 console now returns a mode list.
 - fixed a bug which caused win32 fixed-size windows to be non-minimizable.
 - imported the OpenPTC 1.0.1 DOS VGA fakemode assembly routines - should give
   a nice speed boost on ancient 386/486/Pentium machines.

0.99.7
 - A new event system + mouse support. Yes, I know I should have done this
   earlier :) Fullscreen X11 with mouse still does not work well, I'm planning
   to fix this in the next version.
 - API changes:
    - TPTCKey class renamed to TPTCKeyEvent
    - Removed int32, short16 and char8 types.
      Replaced with: Uint64, Uint32, Uint16, Uint8,
                     Sint64, Sint32, Sint16, Sint8.
 - fixed fullscreen palette modes under DirectX (was buggy on modern NVIDIA and
   ATI video cards).
 - a new example program, demonstrating the mouse support.
   Use it as a reference for now, until I update the documentation with the new
   event handling stuff (hopefully this will happen in the next release).
 - X11 window is not resizable anymore. Maybe some day I'll implement (optional)
   stretching as in win32 windowed mode.
 - code cleanup. Hid some implementation details from the interface part.

0.99.6
 - Now distributed under the terms of the modified LGPL (used by the FPC RTL).
   See the file modified_lgpl.txt distributed with the library for details.
   Thanks to Glenn Fiedler (the author of the original OpenPTC C++ code, that
   this library is based on) and Christian Nentwich (the author of the original
   C code of the Hermes library and the X11 version of OpenPTC) for giving
   permission to distribute the code under this license.
 - The Free Pascal Development Team intends to distribute this library with the
   Free Pascal Compiler and to base the graph unit on it, which is very cool! :)
 - fullscreen support in xshm/ximage mode.
 - dga support is now disabled by default.
 - added workaround for the 'shmat' bug in fpc 2.0.0's rtl on amd64 linux.
 - fixed some compilation-related problems with the example programs.
 - fpc 2.0.2 - go32v2 compilation fixed. fpc 1.0.10 support dropped completely.
 - some other DOS code fixes and cleanups.
 - config file name changed to ptcpas.cfg (~/.ptcpas.conf on *NIX)

0.99.5
 - support for fpc 2.0.0. fpc 1.0.10 support dropped, except for DOS.
 - support for amd64 (the code is now 64-bit safe, but still little endian-only)
 - fix the (sometimes) missing titlebar when using the metacity window manager

0.99.4
 - some X11 fixes (missing cdecl's, wrong alignments, etc.)
 - FreeBSD and NetBSD now compile and work (dga and XShm still not tested...)
 - improved exception handling in demos and examples

0.99.3
 - support for fpc 1.9.2+ (adapted to use the new unix rtl)
 - the dos console uses rdtsc if available for more accurate timing
 - some vesa fixes

0.99.2
 - alt, shift, ctrl modifier keys support for X11
 - key release support for win32 and X11
 - new example (keybrd2) demonstrating the use of key release events

0.99.1
 - first release to sourceforge
