// TODO: The send line request/answer 'L' can be factored out into a regular read 'R' request/answer. All special things for preparation
// like basic address and all lines can be put into one single QByteArray that is transferred in chunks for each request. There is no
// meaning in making this a special command.
// TODO: The error channel can be factored into a regular read-return of a buffer. The buffer is always by the result of the last command
// executed, which might either be resulting error message or some result from a dos command, like M-R and so on.
// TODO: Case handling in Linux, how to support this? Just returning all file entries as they are will not look to good, so best is
// to keep toUpper() for this. But all CD operations and fopen operations need to be able to open file in case insensitive mode somehow.
// TODO: Finalize M2I handling. What exactly is the point of that FS, is it to handle 8.3 filenames to cbm 16 byte lengths?
// TODO: Finalize x00fs handling (P00, S00, R00). The x00fs format can actually handle multiple files as a sort of container to replace M2I. This should be supported.
// TODO: Support x64 format, it should in fact be the preferred format today before D64, D71, D81.
// TODO: Support of images in ZIP archives. Use "osdab" library for zip handling:
// https://code.google.com/p/osdab/downloads/detail?name=OSDaB-Zip-20130623.tar.bz2&can=2&q=
// TODO: Finalize Native FS routines.
// TODO: Finalize ALL doscommands (pretty huge job!)
// TODO: Handle all data channel stuff. TALK, UNTALK, and so on.
// TODO: Display the current error channel status on the UI!
// TODO: T64 / D64 formats could/should read out entire disk into memory for caching (network performance).
// TODO: T64 / D64 write support!
// TODO: Finalize handling of write protected disk.
// TODO: If arduino is reset with a physical button on the board and it tries to resync, the PC-host application should automatically resync without having to press the 'Reset Arduino' button, meaning: listen to unexpecte "connect-request" even in connected mode.
// TODO: When loading directories or media list, the dirlist view doesn't reflect this status.
// TODO: When a file/directory is attempted for loading or saving and this fails for some reason this isn't reflected on the dirlist view.
// TODO: When executing the command channel this isn't reflected on the dirlist view.
// TODO: Native/D64/T64: Show TRUE (actual) blocks free. Will be nice with all the space available on a harddisk or network share!
// TODO: Add icons for disk images in image list view (T64, D64, x64, .PRG, normal folders). This make it much easier to distinguish cbm related files from each other.
// DONE: Rename openHostFile() and closeHostFile() to "mount"/"unmount" respectively on all file systems?
// DONE: Needs to be verified/tested: Need to refactor the open command 'O' so that it is not passed as a CR terminated string. This will never
// work when issued for the CBMDOS command buffer where there can be zeroes and any other character in the buffer that could be
// treated as a termination character. Therefore the 'O' command has to be transferred with a length character in second position.

"<hr>"
"<ul>"
"<li>CHANGE: Dropped need for QextSerialPort, now using Qt's native QSerialPort library."
"<li>CHANGE: Arduino MEGA variants use the SECOND serial port for communication leaving the "
" USB port free for debugging."
"<li>FIX: uchar_prog definition obsoleted, changed to PROGMEM."
"<li>FIX: Fixed conditional compilation so that it is done for all APPLE-based OSes instead of just OSX."
"<li>FIX: Compilation now working again under Windows, Linux AND with multicore build."
"</ul>"
"<span style=\" font-weight:600; color:#0404c2;\">Application Version 0.4.0:</span><hr>"
"<ul><li>NEW: Saving support in 1541 normal speed."
"<li>CHG: Changed much on the UI. Nice icons for all buttons. Separate configuration dialog from main window. "
"Now using Qt Theming, choosing best fit depending on OS. Event log is now dockable and can be hidden or detached. "
"Progress bar now for loading files. The directory image listing is now displayed as a real CBM, can be set to look "
"either like a c64, c128 (40/80 modes), a Plus/4 or a VIC20. Refresh button for file list. Directories in bold font."
"<li>FIX: The sprintf formatting for initial handshake string didn't work for some Arduino Due. Thanks to Lemon64 users for seeing this."
"<li>NEW: Some work has been done on error channel and started work on command channel. In progress."
"<li>NEW: Much work started on M2I support. Now finished, in progress."
"<li>NEW: Settings for file filters and whether directories should be visible or not."
"<li>NEW: Supporting configuration of arduino bluetooth device making the whole project go wireless ! See Readme for info."
"<li>FIX: A LOT of memory optimization on the Arduino side. Reduced ram use to fraction of earlier version. Using PGM memory!"
"<li>NEW: Support for RESET line. Conditional compiling define whether this line is soldered or not."
"<li>FIX: Build location of intermediate files on PC side now much better in .PRO file."
"<li>FIX: Serial optimization for file reading from CBM by keeping interrupts enabled and issuing read before transferring to CBM."
" This is not enabled by default just to be sure, but it can be enabled in global_defines.h header."
"<li>FIX: Size calculation of file and proper transfer of file size to arduino so that progress can be visualized on both sides."
"</ul>"
"<span style=\" font-weight:600; color:#0404c2;\">Application Version 0.3.0:</span><hr>"
"<ul><li>NEW: Added nicely fitting icons for all buttons."
"<li>NEW: Completely revised UI with configuration dialog making main window much more clean. "
"The dialog now also keeps settings for file filters and whether directories should be displayed. The settings dialog "
"is accessed from the menu or with CTRL+O shortcut."
"<li>NEW: Using Qt theming (styles). The default one will be Windows XP, otherwise Fusion."
"<li>NEW: Made the event log sit in a dockable window that can be either hidden or detached from the main window. "
"This will save a lot of screen real estate and gives space for much more files in the file list."
"<li>NEW: The mounted image directory listing is now displayed in classic C64 colors. The image name selection in the file list "
"is also automatically updated even if it is the CBM that triggers a new selection."
"NEW: A refresh button has been added for the file list."
"NEW: Directories are optionally displayed and in such case in bold font weight."
"<li>BUGFIX: When application started it always selected the first com-port in the list even if another was selected when "
"the application exited and the settings was saved. It now selects the right comport when application starts.</ul>"
"<span style=\" font-weight:600; color:#0404c2;\">Application Version 0.2.1:</span><hr>"
"<ul><li>FIX: Faster serial handling. The arduino receives a range of bytes instead of a single byte at a time. Should now be as fast as "
" a real 1541, or at least close to. More optimizations on serial handling can be done."
"<li>NEW: Added this about dialog. It will automatically show every time a new version is released. There is also an application icon "
" and a version resource added for windows targets. A C64 truetype font is embedded to the application for some UI controls."
"<li>CHANGE: Some source and README/NOTES commenting to shape up the things that is left to do."
"<li>NEW: Added skeleton class for .x00 (e.g. .P00) formats."
"<li>NEW: Displays current mounted image content, even automatically when CBM does the operations."
"<li>NEW: Notification interface added so that UI can react to and reflect progress and mounting changes."
"<li>NEW: Some rearrangement of UI controls for better screen alignment and adaptation to windows resizing.</ul>"
