1.0.3 - October 7, 2007

New functionality:

• Support for 300 baud operation to help non-upgraded ROM 255 Apple IIc computers with the serial timing problem

Bug fixes:

• [Client] Only re-scan drives for volume information the first time, and thereafter only when requested; this saves time (and, potentially, drive knocking) whenever the volume screen is shown
• [Client] Removed last dependency on Applesoft string printing; enables running on orignal integer Apple ][ (non-plus) ROM machines
• [Server] Always record 5-1/4" disks at the host as DOS order images
• [Server] Corrected DOS audio addresses coming from bootstrapping instructions
• [Server] Honor the "Apple IIc Serial" checkbox (which disables hardware handshaking) on startup; previously, one had to open the communications dialog box and explicitly hit OK to get it recognized

1.0.2 - August 11, 2007

New functionality:

• [Client] Borrowed very fast Disk II reading routines from FASTDSK (See: http://boutillon.free.fr/Underground/Docs/Fastdsk/Fastdsk_en.html); reduces Disk II transfer time from Apple II to Host by 25%-33%.
• [Client] Refactored client programs as ProDOS 8 system (SYS) applications. This means that saving a configuration no longer BSAVEs the entire client, but instead writes a little config file.
• [Client] Incorporated Bird's Better Bye program selector for Apple II+ users - because the 40-column ProDOS program selector is the very definition of user hostility
• [Server] Eliminated the need for bootstrapping operations to send the ProDOS BASIC interpreter

Bug fixes:

• [Server] The routine to determine physical sector ordering was made more accurate, especially for 5-1/4" disks.
• [Server] Bulk transfers of Disk II images wrote DOS-order images, but named them "*.PO," making it easy to mistake them for ProDOS-order images. Now bulk transfers coming from Disk IIs are named "*.DSK."

1.0.1 - July 8, 2007

New functionality:

• [Client] Support added for Laser 128 serial via generic Pascal entry points on slot 2; included a copy of DOS ADT similarly enhanced

Bug fixes:

• [Client] Unformatted media in an 800k drive would get an incorrect free block count after formatting.
• [Client] Changed bootstrapping to rely less on pure Apple-isms in the monitor. Improved ProDOS stage 1 bootstrapping to not require the tricky control key sequence to get at the comms card from the monitor. This enables Laser and Franklin compatibles.
• [Server] Slowed down default bootstrap pacing to 150ms.

1.0.0 - June 21, 2007

First official public release after one year of beta iterations. Communications methods include:

• Super Serial card, IIgs modem port, or IIc/Laser 128 serial port
• Uthernet Ethernet card
• The Apple's cassette ports

Feature set includes:

• Transfers any storage device ProDOS can access
• Runs on any Apple II (or clone) computer with 64k memory
• Runs on Linux, Mac OSX, OS/2, Windows, and probably Solaris
• Understands many digital disk formats: .DSK, .PO, .NIB, 2IMG
• Serves the original ADT client as well as the updated ADTPro client
• Bootstraps Apple II computers from bare metal over serial or cassette ports
• Sends floppies in "batch" mode without having to name each one
• Formats media on the Apple II end

New functionality over final beta:

• [Client] The formatting function is now integrated instead of being a separate program
• [Client] Volume picker screen sets the default slot/drive for the BASIC interpreter

Bug fixes from final beta:

• [Client] (Finally) fixed audio transfer retry logic - darn Java and its signed bytes! Audio transfers are reliable at last. Slow as ever, but reliable.
• [Client] Fixed 15-character volume name bugs: one in the formatter, one in the online displayer/picker
• [Client] Made the Uther slot-scanning algorithm a little less intrusive, and used a MHz-insensitive timing loop to make UDP timeouts a little more reasonable on accelerated machines
• [Client] Used a MHz-insensitive timing loop to make the delightful beeping noise sound the same no matter how fast the CPU is going
• [Server] Better flow control for serial bootstrapping - improves life for serial interfaces that do their own buffering (i.e. Keyspan USA-28)

0.2.6 - June 3, 2007

New functionality:

• The client will scan slots for communications devices if the manual configuration hasn't been done yet; preference is given to SSC cards over IIgs ports if both exist, and slots are scanned high-to-low, last-one-found-wins
• Included DOS ADT similarly enhanced to scan for serial ports
• Added a simple Applesoft menu when booting the distribution diskette
• Added an 800k distribution disk image
• Server gives instruction messages at the end as well as at the beginning of bootstrap sends for Audio transfers - so you don't have to have the website up in front of you to succeed

Bug fixes:

• Fixed formatter code to more correctly format disks larger than 140k and to recognize and format hard drives/CFFA cards
• Switched diskette image and bootstrapping data to use Apple's publicly available ProDOS version 1.9, BASIC 1.4.1 as downloaded from Apple here.

0.2.5 - May 18, 2007

New functionality:

• Removed the requirement to "install" RXTX - we just point the startup scripts at the unpacked location
• Made an OSX startup script (adtpro.command) and made it double-clickable to start the server

Bug fixes:

• Switching a protocol or hitting the disconnect button puts up a confirmation dialog box if there is an active transfer going on
• Bumped Java heap size in startup scripts with -Xmx128m (Windows) and -Xmx256m (*ix) to support 32M images

0.2.4 - May 12, 2007

New functionality:

• Bootstrapping from bare metal directly to ProDOS
• Made serial bootstrapping pacing and speed configurable - making much higher baud rates possible (and reliable)
• Included a ProDOS floppy formatting utility (because you don't have any formatted disks yet, remember?)
• Saving any 140k disk at the host always creates DOS order images; this increases compatibility with older emulators that don't understand ProDOS order images

Bug fixes:

• Better recovery from initialization when there's no Uthernet card in the default slot
• Cosmetic right-justification issue with online volume block number display (extant since 0.1.1)

0.2.3 - April 26, 2007

Bug fixes:

• Current working directory was being handled incorrectly - not consistently putting a trailing separator character after the path
• Ethernet bootstrap image was missing from resources

0.2.2 - April 24, 2007

New functionality:

• Server-side creature comforts:
  • Added graphical buttons for communications devices
  • Server automatically saves its last window position and size

0.2.1 - April 2, 2007

New functionality:

• Protocol enhanced to always communicate block numbers: enables recovery from lost acknowledgements which can ultimately result in corrupt transfers even if all CRCs match. New version retains compatibility with ADTPro v0.1.x clients with a checkbox in the File menu.
• Added date/timestamps to trace log entries.

Bug fixes:

• ProDOS volumes with full names (15 characters) would walk all over memory, causing a crash when initiating a send. Thanks to James Putnam for going the extra mile to snail-mail me a physical floppy exhibiting the problem as we tried to figure out what went wrong.
• Made RXTX library optional
• Made build slightly friendlier for new developers
• Filled out the Protocol documentation (I'm not saying it's pretty, or necessarily understandable - but at least it matches reality)

0.1.5 - March 18, 2007

New functionality:

• Added support for audio transfers and bootsrapping using a host sound card and the Apple cassette port.
• Apple IIc support (disable hardware handshaking) is now selectable via a checkbox in the File menu.
• Added a logging/tracing capability via checkbox in the File menu. Enabling tracing logs verbose tracing information to a file name ADTProTrace.txt in the server's startup directory.

Bug fixes:

• Managing serial timeouts better fixes two problems:
  • "Hang" when disconnecting on *nix boxes, especially after transfers; though sometimes it still seems to take a while (i.e. several seconds) to fully disconnect after hitting the disconnect button
  • Dropped data on some Wintel chipsets due to (erroneous) rapid toggling of port timeout values

0.1.4 - December 30, 2006

New functionality:

• Ethernet version now has a timeout function at the client end. This addresses one class of problem we have with UDP dropping packets.
• Included DOS ADT 1.31 in the package as well as part of bare-metal bootstrapping function. The main improvement of DOS ADT 1.31 over 1.30 is the capability of self-saving the configuration (no need for the Applesoft configuration program)

0.1.3 - December 15, 2006

New functionality:

• Added support for Ethernet UDP transport via the Uthernet card (http://a2retrosystems.com/). The best reliability is achieved with machines on a wired network in the same subnet (on the same ethernet switch). Sending (Apple/client->host/server) has reliable retry logic since the server, in Java, can control timeout intervals. Receiving is a different story. It won't give you corrupt images, it'll just hang if acknowledgement packets get lost. TODO: add a timeout function to the client side as well.
• Added a batch file for Windows and a shell script for Linux/OSX to start the server

0.1.2 - November 27, 2006

New functionality:

• Added a "batch send" mode to repeatedly send the same volume (i.e. one floppy after another)
• ADTPro server can send the ADTPro client as bootstrap text; the destination Apple would have to already be running ProDOS

Bug fix:

• Split up bootstrap text into lines of 8 bytes each to help the slowest Apples keep up

0.1.1 - November 16, 2006

New functionality:

• ADTPro server now has the ability to serve bare-metal bootstrapping data (ESDOS II, DOS ADT client)
• DOS ADT client enhanced to use either SSC or IIgs native serial communications at speeds up to 115kbps

0.0.9 - September 23, 2006

Bug fix:

• 2IMG images with optional headers/chunks failed to transfer properly - patch also supplied to the AppleCommander project where the bug originated

0.0.8 - September 20, 2006

New functionality:

• You can interrupt the interminable volume scan with the escape key

Bug fixes:

• Cured Linux/OSX's "hang" when disconnecting
• Initiating any communication now resets the comms card - makes things much more reliable with starting/stopping the host end at random intervals
• Greyed out the port/speed buttons on the server while connected to make it more clear exactly what you can change and when
• Turn "cold start" back off again on the client once it's been invoked - to keep from saving the cold start state when the user saves the configuration!
• Switched to cc65/ca65 compiler/assembler suite. See: http://www.cc65.org/. ca65 is compatible with lots more platforms than SB-Assembler, though it is slower.
• Refactored the code to make communications routines somewhat more "pluggable." We aren't quite at the point of device drivers yet, but it's getting closer. I long for the days of the simplicty of ADT's one-file assembly! It used to be so elegant!

0.0.7 - August 27, 2006

New functionality:

• Support for native IIgs serial (modem) port at a maximum rate of 115,200 BPS
• Ability to "cold start" by resetting configuration parameters back to "factory defaults" (useful when a configuration as saved is incompatible with a particular machine: bload adtpro:poke 2052,1:call 2051) Later versions moved this poke by one byte: bload adtpro:poke 2053,1:call 2051)

0.0.6 - August 10, 2006

Bug fix:

• Cosmetic fix for IIgs native send progress indicator

0.0.5 - July 30, 2006

New functionality:

• Support for native IIgs serial (modem) port at a maximum rate of 19,200 BPS

Bug fixes:

• Handle serial port-in-use exceptions at host end
• A few usability tweaks along the way

0.0.4 - July 9, 2006

New functionality:

• Overwrite confirmation when an image already exists at the host
• Option to write mismatched image sizes (i.e. put a smaller image on a bigger disk)
• Host has the ability to change working directory via file dialog

Bug fixes:

• Client configuration-save function uses initial slot/drive combination to BSAVE itself
• Cosmetic changes for buffer send/receive/read/write screen

0.0.3 - July 2, 2006

New functionality:

• Host saves its last known good configuration (ADTPro.properties in startup directory)
• Client saves configuration on demand (it really just BSAVEs itself)

Bug fixes:

• Isolated host messages from client messages to better separate valid messages vs. garbage coming back from the host
• Misc. updates to build process - have AppleCommander build a custom volume name, etc.

0.0.2 - June 28, 2006

Bug fixes:

• Fixed ability to start/stop/restart communications on the host end
• Fixed some Change Directory semantics, particularly for changing relative directories
• Made some minor message improvements at the client end

0.01 - June 21, 2006

First prototypical release on SourceForge. Main functionality:

• Compatibility with Super Serial Card up to 115,200 BPS
• Compatibility with anything ProDOS can read
• Compatibility with any Apple ][ computer with 64k memory
• Compatibility with many diskette/disk image formats: .DSK, .PO, .NIB, 2IMG
• Ability to change working directory on the fly
• Server written in Java, compatible with DOS-based ADT and ADTPro
