New version 1.99 is now available at http://www.tixati.com/download
IMPORTANT: You do not need to uninstall the previous version before upgrading. The newer version will overwrite the old version. Uninstalling clears previous Tixati configuration files, and is not needed to upgrade.

September 5, 2014

Tixati version 1.99 is now available. This release fixes several minor issues in the DHT and other parts of the program, and also offers improved Linux shell integration.

- DHT improved table-refresh behavior after system suspend/resume
- several improvements to DHT peer-db management algorithms for robustness against floods
- compatibility fixes to deal with remote DHT clients that send slightly malformed announce messages
- 20% wider DHT announce pattern to improve reliability in less-populated torrents
- improved remote WebUI performance under heavy file-transfer conditions
- fixed Linux magnet: and dsc: link shell association
- minor changes to Linux ACPI dbus messages for better compatibility
- minor adjustments to Channel streaming algorithms to improve performance with marginal bandwidth
- several additional RSS compatibility improvements
- many other minor fixes throughout the program

We are now working on a major update and will be proceeding to alpha-test Tixati v2.x in the coming months. Further details will be posted when it is closer to completion.

Thanks for using Tixati!


August 26, 2014

Tixati version 1.98 has been released. This version fixes several problems in the RSS reader, and offers improved DHT and file-transfer performance.

- all published items in RSS feeds are now presumed to link to metadata if no other usable media-embed links exist
- RSS feed published items marked "magnet link only" will now be auto-downloaded by default
- work-around for RSS feeds that don't correctly encoded item URIs
- several compatibility fixes in the RSS HTTP protocol logic
- several minor DHT adjustments to further improve search speed
- tweaks to channel connection protocol to improve startup speed
- minor adjustments of UDP Peer Connection logic
- recovery from system ACPI suspend/resume is now much faster on Windows systems
- Linux auto-shutdown improvements, will work on any system supporting ConsoleKit via dbus, otherwise will issue direct command-line shutdown
- Linux ACPI suspend inhibition support on more systems (Gnome/Mate/Freedesktop)
- Linux magnet: and dsc: protocol handler support on more systems
- several other minor fixes throughout the program

Thanks for using Tixati! More updates are coming soon.


August 20, 2014

Tixati version 1.97 has been released. This is a maintenance release that contains many important fixes and several other minor improvements.

DHT Overhaul
- significantly faster DHT search speed
- vastly better protection against DoS and Clone/Flood attacks
- new incoming transaction soft ratelimiting system, to keep overall DHT traffic low under severe network conditions
- better cross-table high network concentration detection heuristics
- IPv4/6 cross-protocol bootstrapping improvements, better compatibility with Teredo systems

Transfers
- overhauled PEX (peer exchange) caching system
- increased maximum metadata size to accommodate extremely large torrents
- sparse file allocation is now the default method on filesystems that support it
- loosened file last-modified time matching rules (in an attempt to stop some reported problems with NAS units)
- eliminated a pause after clicking the Add button in some XP systems
- failing tracker will not fallback to unannounced mode while transfer is in running mode
- minor tracker protocol compatibility adjustments
- no downloading while checking during initialization phase
- fixed a crash in the preload window when Apply To All is checked and Skip Queue is selected

Channels
- overhauled connection certificate caching system for more reliable connections
- using alternate threading strategy for channel stream piece decoding (eliminates a Win7-only handle leak caused by a faulty 3rd party POSIX threading library)
- stream titles show in chat via /streamtitles option
- option to randomize selected stream playlist items
- short duration ts/mp3 files are streamed more smoothly
- fixed several other minor bugs with stream title passthrough to media player
- version column in connections view
- channel-list search IP concentration limits loosened
- several minor protocol tweaks
- channel search function minor fixes

Elsewhere
- fixed problems with POSIX threading library on Win7 platforms (handle leak)
- fixed problems with system suspend/resume on Win7 platforms
- improved SSDP and SLRD local peer discovery port-bind error handling
- minor UPC protocol adjustments
- minor fixes in UPC socket diagnostic charts
- Linux system suspend inhibition is now more reliable
- fixed minor problems in XP systems with saving config files in too large of chunks
- better handling of URLs containing # symbol (in RSS and other places HTTP is used)
- updated IP-Country database

Future/Soon/Next
- eliminate usage of file last-modified times to trigger checking (will instead keep block/file level hashes and use dynamic checking)
- overhaul of transfer multi-file management logic
- further investigation of some Win8 kernel panic problems (we did not observe problems on any of our Win8 systems, and are still trying to track this down)
- replacement of the .torrent auto-load system with something more reliable than the Windows file change notification API
- RSS auto-load / auto-start problems (this has also been difficult to recreate on our systems)
- a report of a Scheduler freezing problem
- overall framework upgrade to a leaner C++11 based system

More updates are being worked on. Thanks for using Tixati!

Tixati 2.15
Tixati version 2.15 is now available. This is a major update that includes new features and several major and minor bug-fixes.
  • optional automatic seed queue management system that rotates seeds in and out of standby depending on seed/peer counts and bandwidth
  • optional download queue auto-skip feature that will start additional queued downloads when bandwidth is under-utilized
  • queue management is fully configurable via XMLe in Settings > Transfers > General
  • dragging transfers can now queue/unqueue them in addition to simple reordering
  • peer/seed counts in status column reflect verified connections and not unverified tracker/dht counts
  • super-seeding improvements
  • several web-seeding fixes
  • several transfer-related GUI improvements
  • outgoing tracker transactions are queued and delayed under heavy load
  • category sub-menus grouped according to last category separator
  • new "codeview" fixed-width font for editing XMLe for menus, socket parameters, and queue management settings
  • legacy .dat configuration files are no longer loaded/saved (they have not been in use since v1.41), which speeds up shutdown
  • relaxed incoming connection rate limits
  • lowered incoming connection timeouts
  • several tracker protocol and timing improvements
  • improved poisoned piece recovery routines (especially with multiple block sources)
  • channel streaming improvements, especially for low bitrates and small segments
  • channel info/share editing remembers state when channel selection changes
  • several other channel-related GUI fixes
  • fixed problems with auto-throttle trace/ping on IPv6-only networks
  • major overhaul of core event loop and task-queuing system for smoother operation
  • eliminated dependencies on win32 pthreads library, most of OpenSSL, and boost::regex
We are working toward a major overhaul of the channels system, including a share/search/browse network that operates independently of channels.

outgoing block request pipelining algorithms adjusted to be more aggressive at higher speeds (>2MB/s)
automatic retry on incoming port bind error window
fixed problems with incoming port errors (EADDRNOTAVAIL) when corrupt addresses arrive via hole-punching
fixed crash when renaming folders in files tab
minor adjustments to run-time profiler for better accuracy
