(Italian, Swedish, Serbian, French, Finnish, English) * Open torrents on close are now automatically resumed on launch. * Typographical correction suggested by Samir Hawamdeh * Program now refuses to start if stack is less than 16384 bytes. * Launch argument PROJECT or TORRENTFILE may be provided. * Bug fixes 2.0 October 19 2018 * DizzyTorrent is now Shareware. * MUI 3.9/4.0/5.0 user interface. * Replaced previous AREXX port with MUI based AREXX port to work like other MUI programs. Default name is DZREXX.1 instead of DZREXX.01 * Multiple simultaneous torrents in 1 program instance. * File Download Prioritization * Performance Improvements * Fix bug in iconfication. Depending on the launch method used Program could always locate the .info file. * Save/Load Project files. Multiple torrents in 1 file. * Added TorrentCount,CloseTorrent ARexx function. 1.11 October 6 2018 * Reduced CPU usage - minor bug introduced a busy-wait not apparent on my test systems. 1.10 September 30 2018 * Since v1.07 CHOKE messages were sent inappropriately, causing some peers to not receive data from DizzyTorrent even though local client is sending. fixed * client may not recognize that a peer has needed pieces to share unless peer has 100% of pieces (since 1.07) - fixed. * Example dz.config file has Delay setting set too high for newer improved throttling mechanism this would cause very slow performance on fast machines. Internal default delay of 0 is now almost always the best. 1.09 September 16 2018 * Fixed buffer overrun bug that would cause application crash on torrents with more than aproximately 60 trackers, or 110 files. 1.08 September 1 2018 * resource balancing, performance, and stability improvements. * Fixed occasional crash when shutting down program while downloading. * Improved support for BEP-20 PeerID Convention using -DZxxxx- PeerID. * Improved support for BEP-10 Extension Protocol - now transmiting Client Version 'v' as well as 'reqq' messages. * file was accidentaly saved with CRLF text format. Not correct AmigaOS LF format. This made it unreadable by Multiview. * New AREXX command - SetThrottleDelay,SetMaxPeers 1.07 August 28 2018 * resource balancing, performance, and stability improvements. * Significantly reduced OS memory fragmentation during process lifecycle. * fixed 5 memory leaks. * DizzyTorrent could try to connect to itself when behind a NAT. fixed. * PeerID was not properly randomized. fixed. * Bug preventing upload to other peers fixed. * Program will now exit automatically if launched with NOGUI and ARexx is not available. (without AREXX or GUI there is no way to control program) * Added BanPeer,UnbanPeer,KillPeer,KillAllPeers, MemReport Arexx commands. * Added more information to GetPeerStatus : ProcessCycles * Added more information to GetTorrentStatus : InvocationTime * Bug which let DizzyTorrent stay connected to an idle peer without any KeepAlive messages fixed. * Improved accuracy of bandwidth throttling mechanism. 1.06 August 2 2018 * AREXX GetTorrentStatus(), GetFileStatus(), GetTorrentFiles() was only updating if the mainwindow is not hidden. * 'About' window now displays ARexx port name. * DizzyTorrent AREXX reference improvements, errata. * Use ReadArgs( )to parse command line switches. Amiga User Interface Style Guide compliant. * New command line switch PORTNAME to set AREXX portname * New command line switch NOGUI to start with no GUI active. * New command line switch SETTINGS to override default settings file * Changes in AREXX Api to use standard Amiga templates. * Removed some some overlap in AREXX Api. * Added AREXX HELP, DizzyTorrent command. * AREXX API now returns error details in RC2 variable. * Created /arexx/ subdirectory and ARexx program dz-status.rexx to allow checking status of DizzyTorrent when there is no GUI * DizzyTorrent AREXX can now be addressed with the ADDRESS command and no longer automatically loads itself as a function library. 1.05 July 18 2018 * Virtually all functionality can be controlled via AREXX, including hidden mode to remove GUI as run as a background resident process. * Moved Documentation into AmigaGuide format * Readme file now only contains history. 1.04 April 5 2018 * OS4.1 FE when the last byte in a file lines up with the piece boundary, program could not complete the download. 1.03 showed error. Earlier versions become slower and appeared to stop downloading. Fixed. * GUI - Torrent comments now adjust wrap width when window it resized. * Hitting cancel on file requestor would cause program to exit without closing shared libraries - fixed. * Morphos 3.9+: SetSocketSignal caused undefined side effects on MorphOS. Replaced with SocketBaseTagList. MorphOS reported that graphics.library can't be opened. * Morphos: Proportional gadget didn't work due to different treatment of excessive PGA_Visible attributed. Fixed. * Minor improvements to GUI cpu efficiency. 1.03 March 30 2018 * Fixed Bug: Peers that didn't complete a handshake could stay alive permanently. * Fixed Bug: a number of illegal memory accesses - (caused grim reapers in OS4.1. Probably caused less frequent problems in OS2 and 3 as well). * Some rules regarding gadgets that OS4 enforces which I can't find documentation of in 3.x, are now followed, removing some grim reapers. * Main window now opens only after the torrent file is read and processed. * A 1-time memory allocation at program launch was missing an associated deallocation - losing as much ram as the filesize of the torrent file. * Peer info page was rendering information about 'suspended peers', which have no current TCP connection. Removed this information. * Improved handling of in-memory peer list. * CTRL-C was incorrectly interrupting sockets. * Trackers are polled less frequently, slightly reducing overhead in torrents with many trackers. * ixemul.library is no longer used or required - increasing stability in OS4 when 2 or more instances are running. * Automatically sets own stacksize to 32kb if necessary. * Errors generated when run from Workbench will automatically open a console window rather than be invisible. * Added sha_taskname configuration setting 1.02 February 28 2018 (AmigaOS 4 Improved Compatibility) * Fixed bug that caused crash in OS4 if menu was activated but no item was selected. * Fixed a bug that cause crash in OS4 if About Window, or Add Peer window was closed with close gadget. * Fixed graphical bug in menus that caused menu to appear grayed out invisible (especially in OS4). * Increased Stack size in .info file to 32000 bytes. * Change default task priority in info file to -10 * dz_FS and dz_SHA1 tasks now copy the parent priority. * DizzyTorrent now appears Amiga OS4.1 compatible (requires Ixemul). 1.01 February 4 2018 (hotfix) * 1.0 added a bug that when when launched from CLI, DizzyTorrent could unlock the current directory, this can cause the shell to freeze or act abnormally after DizzyTorrent terminates. fixed * When launched from Icon, DizzyTorrent would leak a lock on the starting directory. This would prevent you from deleting that directory without rebooting. fixed. 1.0 February 3 2018 (First Official Release) * DizzyTorrent now has a tool icon. * All configuration settings can be set as Tooltypes. * Select a torrent and double click tool to launch DizzyTorrent directly from workbench and start torrenting. * Uncommon crash on exiting DizzyTorrent introduced in 1.0b7-fixed. * "About" window with copyright info. * AppIcon uses DizzyTorrent logo. * Improved protothread control to make GUI more responsive to user. * GUI fixed to work with non-proportional fonts. * Some optimizations. * font configuration can now be set to "default" to use default screen font. * font sizes can be set to -1 to use default screen font size. * "Add Peer" window now opens centered on screen. * GUI scroller gadget now reacts continuously in realtime. * Improved layout of files info page. 1.0 Beta 9 (hotfix) (January 25 2018) * Slightly tweaked load balancing for better performance across wider range of systems. 1.0 Beta 8 (January 24 2018) * DizzyTorrent would terminate immediately with a bencoding error if loading a torrent that had 0 trackers. Fixed. * Show count of Trackers on torrent view page. * A bug in parsing of torrent announce-lists, caused lists to be reloaded repeatedly leading to slow load times and memory waste when loading a torrent with a very long announce-list. Fixed. * Performance improvements. * Passing invalid torrent specification on command line returns with more sensible error message "Could not find torrent". * Beta 7 would output random number seed on start. Removed. 1.0 Beta 7 (January 16 2018) * removed all linkage to pthread library. Smaller binary. Less memory usage. Faster. No dependancy on any LGPL software. * DizzyTorrent now uses non-blocking sockets for UDP. DizzyTorrent can abort while awaiting response. Unresponsive UDP Trackers caused DizzyTorrent to become unresponsive while waiting for UDP to timeout. * Better gui response during Announce. * A torrent with many trackers (dozens), will cause DizzyTorrent to use too many sockets and lead to system instability. Now DizzyTorrent only works on [throttle]concurrent_announce trackers simultaneously, and works its way through the list sequentially. * create new [throttle]concurrent_announce setting in dz.config. Default is 5. * Now seems to work on AmigaOS 4.0 JIT emulation. 1.0 Beta 6 (January 6 2018) * optimization reduces protocol overhead and slightly reduces cpu usage. * Dizzytorrent was not properly indicating when an unsupported tracker URL protocol was detected. (https tracker specifically) * Handles trackers returning a failure with a non bencoded "Invalid Request" html page. * Implemented BEP-24 to discover external IP - but unverified. * Implemented BEP-10 Extension protocol. * Displays peer client version, if peer used extension handshake. * Improve calculation for the proportional gadget and minor layout change. 1.0 Beta 5 (Dec 27 2017) * More SHA1 optimization, about 44% faster SHA1 than beta 4. (SHA1 on 512KB block takes 1.43 seconds vs 2.59 seconds on 50mhz 68030.) * End game strategy improved to reduce redundant download blocks. * Improvements to automatic load moderating to have a better balance of concurrent peers matched to cpu utilization. * Improvement to bandwidth throttling. * Improvements to block request scheduling to reduce protocol overhead. * Fixed bug where throttling would result in closure of peers. * optimized throughput metering code. * Overall downloading with beta5 on a 50mhz 030 using plipbox and AmiTCP 3 is about 12% faster than Beta4. 1.0 Beta 4 (Dec 18 2017) * Performance improvements connecting to HTTP Trackers * Minor SHA1 optimization * graphics text rendering bug on Torrent Details page 1.0 Beta 3 (Dec 13 2017) * Improved operation with torrents with many Trackers. * Improved operation with trackers with many unreachable peers * File progress display bug fixed * aminet back up so hopefully this version can be listed. 1.0 Beta 2 (Dec 12 2017) * DZ would hang when accessing a UDP tracker * Interval timer wrong for UDP tracker 1.0 Beta 1 (December 10 2017) * Presented at World of Commodore Toronto 2017
