Version 08/04/14
----------------
- Support added for the ATtiny24/44/84 14-pin microcontrollers. (Only ATtiny24
  has been tested)

Version 07/11/30
----------------
- The parallel port interface has been greatly modiffied. The main reason for
  this change was to have a convenient way to select the pin assignement for
  this port without recompiling the sources. Now, the pin assignement is
  specified in a configuration file (parallel.cfg) like this:
	 Pin    Bit     Invert
	----------------------
	VCC     2       0
	RESET   4       1
	SCK     5       1
	MOSI    6       1
	MISO    7       0
  In this way, many parallel-port driven interfaces can be configured to work
  with avrprg.
  
- In the command-line version of the program (avrpcmd) most of the debugging
  output is now supressed unless the verbose switch (-v) is specified. Before
  this change, important error messages were difficult to notice as they were
  intermixed with lots of irrelevant messages.

Version 06/11/21
----------------
- Port to windows. Requires Cygwin. Some conditional compilation added.
  Timming is done via RDTSC in the windows port. No graphical interface under
  windows. Only parallel port interface supported under windows.

- Bug removal 07/04/09: Signature bytes for ATMEGA88

Version 06/11/07
----------------
- All delays shorter than 10ms are now done via the "udelay" function. This
  function is calibrated to give a delay of an integer number of microseconds.
    
- Delays after fuse programming are moved to their "proper" places.

- The "poll RDY" command is used during flash/EEPROM programming and chip
  erasing when the chip supports it

- Support for the ATMEGA48/88/168 chips added (only ATMEGA48 tested).

Version 06/09/29
----------------
- Added a command line driven program: avrpcmd
    This program is much more suitable for the automation of chip programming
    and erasing via scripts or makefiles. It is also useable on systems with
    only text mode consoles or without the XForms library.
    
- Added support for the ATtiny2313 MCU

- Bug fix: A 10ms delay is added before exiting the RESET state (Function:
  set_Vcc_L(), files: xxx_lowio.c)   This is enough time for the completion of
  the last write command. This fixes the bug that prevents the programming of
  fuse bytes through a parallel interface.
  
Prior versions
--------------
No detailed log was maintained prior to version 06/09/29. Chronologicaly these
were the main changes:

about 2005 (major changes):
---------------------------
- Added a page programming mode to give support to ATMEGA chips: ATMEGA8,
  ATMEGA16(untested) and ATMEGA32.
- Added a fuse reading/programing window.
- Added support for a parallel port programmer.

about 2004 (minor changes):
---------------------------
- Added a raw I/O support for serial interfaces. This was due to the need to use
  this program with really old Linux kernels lacking the TIOCCBRK ioctl call.

about 2003 (first version):
---------------------------
- Provides support por programming the AT90S2313 and AT90S1200 (untested) chips
  using several custom serial programmers/ISPs. A graphical interface is built
  around the XForms library. A Hardware test window eases the checking of
  homemade programming interfaces as it allows the individual testing of each
  SPI bus line.
