2008-11-21 sd-reader	* support for SDHC cards (disabled by default)	* support for FAT32 (disabled by default)2008-06-08 sd-reader	* new "init" command to allow reinitialization of memory card	* fix searching through multi-cluster directories	* fix reading directory entries spanning a cluster border (backport from mega-eth)	* do not abort the whole lfn entry when the file name is too long, just drop single characters (backport from mega-eth)	* change fat16_get_dir_entry_of_path() to ignore a slash at the end (backport from mega-eth)	* make listing a directory's content much faster (backport from mega-eth)	* shrink code size by centralizing cluster offset calculation (backport from mega-eth)	* some other small fixes and optimizations2007-12-13 sd-reader	* dual-license the major implementation modules under GPL and LGPL2007-06-03 sd-reader	* Fix reading beyond cached block (by Benjamin Meier).	* Implement support for reading and writing file modification dates/times.	  (Thanks to Torsten Seeboth for testing.)2007-03-01 sd-reader	* Avoid LFN directory entries for the "." and ".." directory references.	  This prevented Windows from deleting directories.	* Handle special case where the 8.3 filename begins with 0xe5.	* Fix return value of fat16_delete_file() when deleting empty files.	* Fix fat16_clear_cluster() which was zeroing only 16 of every 32 bytes.2007-01-20 sd-reader	* fix directory creation	  - correctly create "." and ".." directory entries (8.3 <-> lfn versions)	  - correctly clear cluster containing the directory entries for new directory2006-11-01 sd-reader	* Implement creation and deletion of directories.	* Clear the directory entries of new directory clusters.	* Prevent linkage against printf().	* Make the use of malloc()/free() optional.2006-09-01 sd-reader	* Fix shortening files.	* Fix free disk space calculation.2006-08-24 sd-reader	* Improve sleep handling.	* Display extended card information on boot and	  when executing the "disk" shell command.	* Correctly determine FAT type by cluster count.	* Fix cluster allocation beyond card capacity.2006-08-16 sd-reader	* Provide FAT16 capacity and usage information.	* Implement the backspace key in the mini shell.	* Enter idle mode when waiting for uart activity.	* Make the Card Select pin MCU dependent as well.	* Add mini shell commands to documentation.2006-08-08 sd-reader	* Thanks go to Torsten Seeboth for his ongoing efforts	  to test changes, fix regressions and give suggestions.	  Many of the changes below were initiated by him.	* Much more reliable card initialization.	* Highly improved performance	  - optional write buffering	  - better cluster handling	  - remove unneeded SPI access when reading from buffered block	  - use highest spi frequency after card initialization	* Add superfloppy support.	* Better checks when opening a FAT16 filesystem.	* Provide SPI pin mappings for commonly used ATmegas.	* Fix resizing files, hangs could occur.	* Fix overflow when creating files with names longer than 31 characters.	* Fix numerous other small things.2006-03-19 sd-reader	* Fix speed regressions.2006-03-16 sd-reader	* Initial release.
