August 27, 2022
Tixati version 3.11 has finally been released. There have been many changes throughout the program.
New BitTorrent v2 Support
A full BEP-52 implementation has been added to the program. The primary benefit of this is the use of the block-level SHA-2 hash function instead of SHA-1 at the piece level. However, there are also many other changes from the v1 protocol that required a major review and re-write of the torrent/peers/trackers/pieces core logic. Combined version 1+2 torrents are also fully supported.
Trackers
All tracker function has been completely replaced with a newly-written implementation. Dual-protocol and dual-interface announcement is now fully supported for each individual tracker.
A tracker presets feature has been added, which can be accessed from Settings > Transfers > Trackers. These presets can be set by simply right-clicking any transfer in the main window and using the Trackers sub-menu. They are also accessible from the standard tracker-edit dialog, the transfer preload window, and the new seed creation dialog.
A default preset for newly-loaded transfers can also be selected in the settings window. This will be set into non-private transfers, upon loading, before applying the Individual Tracker Options.
Peer Connections
The peer connection logic has been largely re-written with major improvements in several areas. This was needed to accommodate the new v2 protocol messaging requirements, in particular the piece selection algorithms and file hash field synchronizing with other peers. The new implementation takes full advantage of the fact that when a transfer is only downloading a subset of files, the new v2 protocol allows clients to only download hash data for files that are needed. If managed correctly, this saves bandwidth, time, and memory, especially for extremely large torrents when only a few files are needed.
It was also necessary in hybrid swarms to allow dual connections so peers can communicate over v1 and v2 simultaneously. This is sometimes required for situations where there are many v1-only clients in a swarm and v2 hash-info is not fully available, which, when following the specification as-written, prevents pieces from being available over the v2 connection.
The peer connection selection and management algorithms have been completely replaced with much more modern versions that can efficiently handle multiple ports connected from the same IP, perform regular peer-ID duplicate detection, and prioritize connections based on their protocol and piece availability. Unusual situations such as losing pieces, or going from complete state to incomplete state, are now handled with great precision. The process for gathering meta-info from peers has also been greatly improved and is much faster when dealing with extremely large torrents.
Web Seeding
Support for web seeds has been completely overhauled. Peak speeds are much higher and far less CPU usage is needed to maintain a continuous flow of data.
For better control over web seed connections, a brand-new Web Seed Request Limiter has also been created. This is available from Settings > Transfers > Peers. Simultaneous connections can be globally limited based on host name, and other rate-limiting/throttling parameters can also be set. Rules can be customized for different hosts.
DHT
To provide peers to dual-protocol torrents, it was necessary to modify the DHT engine to schedule separate search/announce procedures for each protocol ID-hash that a particular torrent requires. A major review and update of the DHT code was done to support this and also to add several other DHT protocol updates. These updates were made in order to support upcoming Tixati features like mutable torrent support.
New Seed Creator
The seed creator (third tab in the Add window) has been completely replaced. The new dialog allows flexible creation using files from different parts of the local file system, and will also let the user change the virtual-name of files and folders. This enables you to fully customize the file structure in the torrent meta-info without needing that same structure replicated on the local file system.
There are also numerous new options to select tracker presets, protocol and padding options, piece sizes, comments, and other technical parameters. A full host of default options can be changed from the settings menu, including full control over the default piece size selection algorithm.
You can also now drag-drop files and folders from the operating system directly into the transfers view to create new seeds. When the Categories feature is enabled, you can drag-drop directly onto a category, or into the main view when a category is selected, and the new seed will be created in that category.
File and Piece Handling
All file handling logic has been revised. The file-checker has an improved combined SHA-1 and SHA-2 multi-threaded piece reading and hashing pipeline, which will thoroughly cross-check all incoming and existing data in hybrid v1+2 torrents. Checking speed has also improved on multi-CPU systems.
For v2 torrents, all incoming 16K blocks are checked immediately upon download instead of waiting for full pieces, so malicious peers are eliminated from the swarm much quicker.
New Tracker Options for Categories
In the category properties and add windows, there is a new Trackers tab. This contains an option to set a tracker preset on any transfer entering the category. These options are also reflected on the category right-click menu.
There were also several minor fixes to the category system. The right-click options for a category separator now correctly control all categories following. The Share sub-menu on categories has been fixed to show the checkbox states for channel mirroring correctly.
Several Channel GUI Fixes
The recently re-written color text controls that power the chat rooms and user browse window have undergone a few more changes to perfect the way scrolling and back-buffering work. There were also other optimizations and adjustments to the background word-wrap updating routines and timing to further minimize CPU usage after a window full of text is resized.
In addition, we fixed some minor problems with the channel restrictions window updating after rule changes, and also some word-wrap anomalies when switching between chat rooms.
New Columns
Transfers have two new optional columns, available from the Layout button menu in the main transfers view. The Protocol column will show v1, v1+2, or v2. The Trackers column will show the name of the current preset. If there is no matching preset, either a hash identifier of the set (to be able to identify matching transfers) or in the case of only having one tracker, the tracker URL itself. The tooltip in this column will always show the full set of tracker URLs.
Peers also have a new optional Protocol column. This shows either v1 or v2 for regular peers, or HTTP or HTTPS for web seed peers.
Many Other GUI Improvements
A new find-bar has been created for the Files tab in the main transfers view, and also the preload window. Press CTRL-F when the view is in focus to make the find-bar appear at the top. You can also use the F3/shift-F3 keys to step through matches.
When new transfers are loaded, they are now selected and scrolled into view, including changing selected category if need be. This works for any manually-created transfers, including pasting in magnet links via CTRL-V, drag-dropping .torrent or .magnet files, or creating new seeds.
There have been dozens of other minor tweaks and improvements to the GUI, and several optimizations to reduce interface CPU usage on both GTK and Windows builds.
Several Other Core Fixes
During the course of development of this version, there have been countless other minor fixes and refinements made as problems were discovered. Many opportunities for optimization were explored, and much testing was done. We also analyzed all outstanding automated crash reports and applied several minor fixes. This is the smoothest running Tixati that we have ever produced.
More To Come
We are working on several other major improvements to the transfers and channels systems, including file merging, channel feeds, and more protocols.

Version 2.53 is now available. This is a major upgrade with several important fixes and improvements.
All channels now have a fully decentralized forum that is available next to the Chat tab. Messages are organized into a threaded view, numerous layout options are available, and a full set of moderation controls allow the channel's operators to maintain their forum. Private messages between users can also be posted and are encrypted against the recipient's public key.
Other aspects of channel operation have been greatly improved as well. Shared user data, such as links, text, and forum messages, are now automatically segmented with a much more intelligent algorithm, which minimizes the bandwidth used to propagate changes when a small amount of content is added to a large shared collection.

Thanks for using Tixati!
April 17, 2015
Tixati version 2.11 has been released.
This new version features a complete makeover of the channels system and its UI. There is now a common Share view that has a default profile for all channels. There is also a new search view that works on all channels, and a contacts list for easy access to friends. Streaming options have been improved, and the channels themselves have been carefully refined and tested for smoother operation.
There have also been several UI refinements made, including several new top toolbar options in the main view. Right-click the toolbar and look in the Layout submenu to select the different styles.
We have also made several refinements to the bandwidth throttling routines, so that payload packets to a particular endpoint are larger and more sparsely sent out on the wire. This will reduce protocol overhead and improve download and upload performance on high bandwidth connections, and will slightly reduce CPU loading.
The DHT has also had some minor work done to the internal logic. This was mostly to further increase the speed of DHT lookups, and mitigate the impact of certain other clients that are abusing the DHT network with excessive requests.
The Linux version is now built on an updated toolchain to utilize the newest language features and several standard library improvements. Some users may notice better CPU/memory performance on 64-bit Linux machines.
The next release is coming soon and will contain many new improvements to the transfer queuing system, as well as webseeding support.
Thanks for using Tixati!

January 20, 2013
Tixati version 1.93 is now available for download. This release features a new Web UI as well as several important bug-fixes and improvements.
The Web Interface can be activated from the main settings window under the User Interface > Web Interface view. The interface is fully customizable via template files, however the default implementation should be adequate for most uses and has been designed for maximum compatibility with different browser configurations and does NOT need JavaScript. More work on the default template (including adding some non-invasive scripting to disable controls when there is no selection, etc.) will be done in future releases.
Trackers should now handle non-compliant HTTP responses more robustly, further increasing compatibility. Upload/download totals on transfers over 4GB should now be handled correctly.
A few bugs writing large files over 4GB have been corrected.
File checking will no longer be triggered by general file-system errors and will only be triggered by a last-modified time mismatch. This should alleviate problems when networked storage becomes temporarily unavailable.
Several other minor GUI bugs have also been fixed.
Another release is being planned soon with several fixes in the RSS reader and a possible replacement to the file/folder selection dialogs in Windows versions (these have been causing delays upon clicking the add button). We are also working on some issues specific to Windows 8 performance.
Thanks for using Tixati!
August 30, 2012
Version 1.92 is now available. This update features important usability improvements, some new features, and dozens of minor fixes and improvements.
There is now a function to undo the last transfer remove operation. This is available in the popup menu that appears after clicking the Remove button in the main transfers view. Transfers can be restored to the exact same state they were in, including peers and file selection, for up to three minutes after they have been removed. After three minutes, memory and other resources are reclaimed by the system.
Transfer downloading algorithms have been improved to reduce outgoing interest in seeds when downloading from too many sources. If the outgoing bandwidth throttle is being hit, transfers will reduce interest to try to download only from the 10 fastest sources. If the throttle is not being hit or is not set, an advanced algorithm is used to reduce interest in seeds that are not providing statistically-significant bandwidth (such as a seed that provides 1K/s in a transfer with several other seeds providing >100K/s each.) This has resulted in a reduction of protocol-related bandwidth overhead, and improved file-transfer speeds.
Standard SSDP-based local peer discovery has been added as an option for transfers. This feature defaults to inactive (for top security on unsecured LANs), but can be set so that all transfers are announced, or just a few can be enabled individually via the Options tab for the transfer. The announcement protocol is the same SSDP over multicast protocol used by other clients, and is fully compatible. However, it should be noted that this protocol, while compatible with other clients, uses no encryption and allows anyone else on your LAN to theoretically identify and log any transfers that are being announced.
Channels now have the option to use the new Secure Local Resource Discovery protocol to gather channels and find channel peers from local sources. This protocol uses encryption and prevents other users on your LAN from knowing what is being announced unless they have specific foreknowledge of the channel/resource.
Portable-mode can now automatically associate with magnet/dsc links and .torrent files. Tixati-portable will remember the state of association before it was altered and restore it when the program exits, leaving the system unchanged.
Tracker handshake format has been tweaked for better compatibility with trackers that monitor bandwidth usage or ratio. The ordering of fields has been changed, and separate byte counters are kept for each individual session.
Decentralized Sharing Channels have had numerous minor improvements as well. The streaming engine for .ts files has been adjusted for more accurate pacing (delete and re-add .ts in playlists to reset the segments with better pacing.) The settings for channel defaults can now optionally be applied to all existing channels. Tooltips on user names in the chat message window will also contain the message time. Automatic permission issuance has been tweaked for more rapid action upon operator commands.
There have been several other minor improvements and fixes throughout the program.
Thanks for using Tixati! Please tell your friends!
August 10, 2012
Version 1.91 is now available. The new version features many important optimizations and fixes throughout the program, as well as vastly improved media streaming within channels via a new outgoing playlist interface and .mp3/.ts file support.

This version features a complete overhaul of Tixati's local file handling.
Individual files within a transfer can now be independently moved to any location on your hard-drive, even while downloading or seeding is in progress. Files, folders, and entire transfers can also be renamed with ease, without interruption.
Files that are unselected (red X in the download column) now have a Delete option to remove them from the local hard-drive. A forced-check can also be initiated on individual files.
The sequencing of checking/allocating/moving operations has also been greatly improved. The operation queue is now device-aware, and will allow allocation or move operations to carry out concurrently if they are not using conflicting devices.
Numerous other minor aspects of file handling have been improved, such as default file permissions, locking, head+tail priority widths, fast-allocation algorithms, rechecking criteria, and error handling.
There have also been several other minor improvements in other parts of the program. Magnet links will now resolve immediately, even if the transfer is locally queued. The RSS reader has a few new feed compatibility work-arounds. Many GUI fixes have been made.
Further improvements to several other areas of Tixati are in the works and will appear in upcoming versions.
Thank-you for using Tixati!
June 20, 2012
Tixati version 1.87 is now beta-testing. This is a major update to file handling functions and other important parts of the program. Please visit beta.tixati.com for more details and updates during the test.
April 13, 2012
Tixati version 1.86 is now available. This is a minor update that fixes a few display formatting problems in the bandwidth and DHT charts.
April 12, 2012
Tixati version 1.85 is now available.
This version introduces a new fully-decentralized media streaming technology, and several other improvements and fixes throughout the program.
Tixati's already fully-decentralized channels now feature the ability to efficiently stream audio and/or video to all other users in the channel. Our groundbreaking streaming technology is built around mixed-coefficient linear network coding, which provides significantly higher swarm throughput than all other conventional methods. Coded blocks are also secured against tampering by downstream peers via a combination of elliptic-curve and lattice-based homomorphic signatures. This is the world's first practical implementation of fully-decentralized network-coded streaming. More information about the streaming technology and how you can listen or make your own stream can be found on our streaming help page.
A native Windows 64-bit build is now available. For users with 64-bit systems, this new build will deliver noticeably improved performance.
The IP Filter feature now supports the use of ISO 3166-1 alpha-2 country codes in place of a URL to a blocklist file. The IP ranges used for country filtering are the same ones that power the flag column in the peers view. This IP-country table is compiled using records from all five regional IP registries, and is fully updated in every new Tixati release.
IP Filters are now fully IPv6 operational. This includes checking Teredo and 6to4 addresses properly against both the IPv6 and IPV4 list for a match. IPv6 addresses can also be included in blocklist files. For a description of the format and some example files, please see the IP Filter help page. Tixati is now 100% IPv6 compliant in all parts of the program.
The popup menu for files within a transfer has a new Open Location option, which will open the containing folder in your operating system's file explorer.
Tree and list views now use the left/right arrow keys to expand/collapse folders, and ctrl-left/right to scroll the view sideways. This allows easier navigation. Files will now launch if they are selected and the enter key is pressed.
In tracker URLs, a :header: directive may be added to the end, followed by URL-encoded HTTP header line(s) that are to be used in place of the regular UserAgent line. A :peerid: directive may also be used on the very end of a tracker URL (after :header: directive, if present) to override the peerid parameter for a single tracker. For more information, see the trackers help page.
Further compatibility improvements have been made to Tixati's Universal Plug and Play functionality. Incoming ports will be automatically mapped on an even wider range of broadband routers that support the UPNP specification. If anyone still experiences problems, please leave us a note on our forum, including the make and model of router, and the UPNP log output, which can be found in the main Help menu under the Diagnostics section.
Numerous other minor improvements and fixes have been made to Tixati's GUI and core, as well as several performance-improving optimizations for both 32 and 64 bit editions.
Further improvements, both major and minor, will be coming in the following months.
Thanks for using Tixati and enjoy the new version!

• several other minor user-interface improvements and bug-fixes
January 6, 2012
Tixati version 1.82 is now available.
This version introduces Decentralized Sharing Channels. These allow you to share, search, and chat with other users in purely decentralized channels that anyone can create.
Other changes include:
• vastly improved magnet-link creation options
• all GUI fonts fully adjustable
• improved configuration file storage and fail-safe procedures
• several DHT fixes and improvements
• much better PEX performance in torrents with very few users
• updated IP-Country database

October 2, 2011
Tixati version 1.74 is now available.
This is a minor update that offers improved tracker compatibility. A few minor GUI glitches have also been fixed.
October 1, 2011
Tixati version 1.73 is now available.
The DHT implementation has been fully revised for this version, and now includes full IPv6 support that complies with the BEP-32 standard for IPv6 DHT operations. Several other major DHT improvements have been made, including much faster searches, better node table management, better resistance to eclipse attacks on the network, and better resistance to IPv4 cache-flooding problems caused by interactions between symmetric NAT routers and other poorly-written clients. Both IPv4 and IPv6 tables now have multiple bootstrap nodes available for smooth entry into the network after fresh installation or if all cached nodes are lost.
The HTTPS protocol is now supported on tracker and RSS feed connections. This includes all common versions and ciphers of SSL/TLS.
Trackers within transfers have been optimized to consume much less CPU in aggregate, even if you have several thousand operating concurrently.
Additional user-configurable rules have been added to the Auto-Limit feature. It is now possible to add rules that cause throttle changes when pings are completely lost, which helps avoid congestive-collapse on some types of internet connections.
Several important bug-fixes and performance improvements have been made to the way Tixati interacts with the network. UDP Peer Connections should now perform even faster and offer improved reliability. Outgoing TCP connections to SOCKS/HTTP proxies are also much more reliable now, and have been fully tested with TOR and SSH clients in both Windows and Linux.
Several other minor user-interface glitches and bugs have been fixed.
Enjoy the new version!
September 1, 2011
Tixati version 1.72 has been officially released. This version contains several important performance upgrades and many other fixes and improvements.
UDP Peer Connections
Tixati now supports UDP Peer Connections. Our implementation is fully compatible with other clients, but also contains many key improvements to provide vastly better congestion avoidance characteristics, better security, TCP friendliness, and much higher top speed. We have experienced very good results in both emulated and real-world network environments, under a wide array of loss, re-ordering, and delay conditions.
Several new options have been added to Settings > Network > Connections. These allow control over protocol preference and connection timing, including the ability to fully disable TCP or UDP peer connections.
A UPC monitor has been added to the diagnostic tools. This shows a list of all connections including detailed statistics, as well as charts of congestion window sizes, round-trip times, time stamp data, and loss rates.
A UPC log window has also been added to the diagnostic tools. This can optionally log several aspects of socket operation, including raw packets.
UDP Hole-Punching
Tixati now supports incoming and outgoing UDP hole-punching, compatible with all other clients supporting the common "ut_holepunch" extension. This alleviates the need to map an incoming port through broadband routers and firewalls that use network address translation (NAT).
New PEX Core
The PEX (Peer EXchange) engine has been completely rebuilt from scratch. This was needed for optimal operation of UDP Hole-Punching, and should perform much better than previous versions. A much higher connection success rate is now achieved due to these changes.
New Throttle Timing Core
The engine that controls the timing and spacing of both UDP and TCP packets has been re-engineered to raise the minimum packet size under heavy bandwidth restriction. This helps improve throughput by maximizing the average ratio of packet data to packet header.
CPU usage under heavy throttling should be a bit lower now as the throttle now works under a single-pass algorithm as opposed to the previous multi-pass system which would need to repeat many times per cycle.
New Base Sockets Event Notifiers
The Linux event mechanism for sockets is now EPOLL-based instead of the old Realtime-Signals system. This allows events to be processed with far fewer system calls and switches between threads.
Both the Windows and Linux event mechanisms are now mostly lock-free, which also eliminates many system calls.
Multi-Priority Task Engine
The way in which Tixati handles its various background duties has now been organized into priority levels. This means that low-priority tasks (such as offline-checking file pieces) will not interfere with regular tasks (processing peer messages or saving pieces) or high-priority tasks (servicing UPC or the throttle). This should also improve interface responsiveness.
The task engine has also been made lock-free, eliminating thousands of system calls per task-cycle.
Minor Protocol-Compatibility Improvements
HTTP connections are more reliable and compatible than ever. We made several improvements that allow Tixati to operate reliably with servers that use uncommon keep-alive or compression schemes.
Peer connections now also support the "upload_only" extension within the inner "m" LT-EXT dictionary as opposed to the traditional field of the same name used in the outer root LT-EXT dictionary. This was observed on the open internet in a common client and added for the sake of better compatibility.
Miscellaneous Other Fixes/Improvements
Several other minor improvements and fixes have been made within the GUI. A new "Link" column has been added for peers. Auto-Shutdown can now optionally wait for both downloads and seeds to complete. Several other minor fixes have been made.
August 24, 2011
Alpha-testing of version 1.71 has begun.

Jan 26, 2011
Version 1.52 is now available for download.
The following changes/additions were made:
• Files in all views are organized in their original folder structure, with ability to disable or adjust priority on entire folders. This option is on by default but can be toggled in the Layout menu under the Files sub-menu.
• Icons are next to files in all views. The icons correspond to the different file types, as you would see exploring files in the regular shell. This option is on by default but can be toggled in the Layout menu under the Files sub-menu.
• Separate downloading and seeding default bandwidth presets can now be selected. This can be done from the Bandwidth Presets window accessible from the system-tray menu. Whenever Tixati transitions to or from fully-seeding state the default for the new state will be activated.
• A category bar that can filter the list of transfers by state (downloading/seeding/queued/off) has been added. This bar can be activated in the layout menu, and is off by default.
• A popup window to activate/deactivate optional columns has been added to replace the old system of checkboxes in the layout submenu.
• Additional double-click option "Open Location/Folder" is now included. This will open the location folder when a single-file transfer has been clicked, and open the base folder of multi-file transfers.
• The Open-Folder option in the main context menu is now also available for single-file transfers, in which case it opens the download location.
• New Import/Export functions have been added. These are accessible from the main settings window. This function can save all transfers, RSS feeds, scheduler items, IP filters, and settings to a single data file that can later be imported on a new system.
• In the Settings under the Transfers > Metadata section an option has been added to delete .torrent files upon loading from a specified directory.
• The ability to batch-save .torrent files from a multiple selection of transfers has been added. If multiple transfers are selected, Tixati will prompt for a destination folder and save a .torrent file for each selected transfer under its standard name, appending (1) to avoid conflicts with any existing .torrent files.
• An option to allow more permissive file last-modified time checking has been added in the Settings under the Tranfers > Local Files section. This option is off by default (99.99% of users will never need it) but is necessary to work-around file-systems or file-servers that may delay updating the last-modified time after files have been closed.
• Several other minor improvements and bugfixes have been made.
