What's new in this version:

- channel private messages flash the tray icon (optional, default on)
- channel activity when view unfocused optionally changes tray icon (default off)

- minimum peer automatic re-connect time has been shortened, especially when few other peers
- problems with extreme numbers of incoming connections flooding out established peers have been eliminated
- peer local-interest throttling now allows slightly more (~20%) sources when bandwidth throttle not hit
- final transfer tracker handshake upon program exit now reports absolute latest download/upload byte counts
- updated IP address to country tables, now includes all allocations up to May 7, 2013
- fixed problems with rss-created transfer meta-info
- fixed problems with menu context (top/bottom pane mismatch on file commands) in split DL/Seed layout
- compatibility improvements for Win8 systems

What's new in this version:

- 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.

What's new in this version:

- 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.
