Tixati 1.97

Tixati is a free and easy to use BitTorrent client featuring detailed views of all seed, peer, and file transfer properties. Also included are powerful bandwidth charting and throttling capabilities, and a full DHT implementation.

Why choose Tixati?
Tixati is one of the most advanced and flexible BitTorrent clients available. And unlike many other clients, Tixati contains NO SPYWARE, NO ADS, and NO GIMMICKS.

Tixati has the following features:

detailed views of all aspects of the swarm, including peers, pieces, files, and trackers
support for magnet links, so no need to download .torrent files if a simple magnet-link is available
super-efficient peer choking/unchoking algorithms ensure the fastest downloads
peer connection encryption for added security
full DHT (Distributed Hash Table) implementation for trackerless torrents, including detailed message traffic graphs and customizable event logging
advanced bandwidth charting of overall traffic and per-transfer traffic, with separate classification of protocol and file bytes, and with separate classification of outbound traffic for trading and seeding
highly flexible bandwidth throttling, including trading/seeding proportion adjustment and adjustable priority for individual transfers and peers
bitfield graphs that show the completeness of all downloaded files, what pieces other peers have available, and the health of the overall swarm
customizable event logging for each download, and individual event logs for all peers within the swarm
expert local file management functions which allow you to move files to a different partition even while downloading is still in progress
100% compatible with the BitTorrent protocol
Windows and Linux-GTK native versions available

Tixati version 1.97 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
