tribler

This release features a major refactor of Tribler Core for stability and performance and adds support for creating multiple personal channels with nested folder-like structure. Below, we list all major changes to the Tribler core and user interface. A comprehensive list of all minor changes between Tribler 7.4 and 7.5 can be found in the changelog of the release candidates.

Core

• The Tribler Core is now powered by the modern Asyncio framework which improves performance, reliability and compatibility.
• REST endpoints are now based on AIOHttp framework.
• The video player is completely rewritten, improving its performance.
• Tribler channels now support multiple channels per user with file-tree like nested structure.
• DHT requests are now anonymous by default.
• Improved the startup time of the core.
• Discovering the first Tribler channels on new installations is now much faster.
• The integrated market is disabled by default and can be enabled from the setting panel.
• The experimental 'Credit mining' feature is removed completely.

User Interface

• The home screen is removed; instead, Tribler now first shows the discovered channels.
• The torrent metainfo is loaded directly from DHT/tracker when unchecking the "anonymous" checkbox.
• The CPU-hungry animation of "loading" channel state is replaced with a static icon.
• You can now refresh the current page by clicking the selected button in the left menu again.
• Numerous small Channels GUI improvements.

Known issues:

• The 32-bit Windows version of Tribler lacks some VLC codecs.
• A newly subscribed channel is not immediately shown in the "Subscribed" list when the user subscribes to a channel. A workaround is to click on the "Subscribed" button an additional time to force refresh the list.

Attention, owners of big channels!
Previous versions of Tribler (7.3+) contained a bug that could have resulted in the corruption of the personal channel torrent. This release fixes the bug, and will automatically re-commit the channel in case it was corrupted. However, if your channel is very big, Tribler will appear stuck for a long time. We apologize for the inconvenience.

This is the sixth release candidate for Tribler 7.5 series. It features numerous bugfixes and some minor usability improvements over 7.5-rc5.

This is the second release candidate for the initial release of Tribler 7.5 series. All reported crash-inducing bugs from 7.5.0-rc1 were fixed, including the "pending task" crash and DNS-related crashes.

This is the first release candidate of Tribler 7.5.0 release. It features numerous bugfixes and some performance improvements over the the previous, experimental releases.

This is the fourth experimental release of the Tribler 7.5 series. Compared to 7.5-exp3, it fixes a problem with adding downloads through the REST API.

This is the third experimental release of the Tribler 7.5 series. It features numerous bugfixes for bugs reported in exp1-exp2 releases. Also, it includes a completely refactored Streaming Video component that is now based on AIOHTTP.

So far, major features introduced in 7.5 series:

• Asyncio-based reactor (improves performance, stability and response times of the Core)
• Nested Channels Core and GUI support. Users can now create and maintain an unlimited number of personal channels with arbitrary sub-tree of "folders" for organizing personal content.
• Home Screen is removed in favour of Discovered screen
• Startup time is greatly improved, along with Channels performance.
• Video streaming works again.
• DHT requests go through Tunnels by default to improve anonymity.

Known issues:

• in a nested channel, a folder's state will be wrongly indicated as "Preview", even though the contents are shown in full;
• seeking a video stream does not always work;

This is a second experimental release of Tribler 7.5 series. Aside from switching to Asyncio and Nestec channels introduced in 7.5.0-exp1, this version contains numerous bug fixes and performance improvements.

As usual, it is advised to backup your Tribler state directory before trying it out.

Known problems:

• removing torrent with data does not remove the data;
• in a nested channel, a folder's state will be wrongly indicated as "Preview", even though the contents are shown in full;

This is the first experimental release of the new 7.5 Tribler series. It features 2 major changes:

• Nested Channels. Users can now create more than one personal channel. Channels now can feature an arbitrary sub-structure of folders, just like in a real filesystem. Also, the Channels GUI was refactored for speed.
• AsyncIO reactor. Tribler now uses modern AsyncIO reactor instead of the old Twisted framework. This should help with performance and stability.

Overall, the Core of Tribler was heavily refactored for this release.

This is the fourth bugfix release of Tribler 7.4.x series.
It fixes Tribler crashing randomly with lambda message. Also, it includes a backport of 7.5 fixes for TorrentChecker SQL queries, which improves performance for people with big Channels databases.

• Removed set_filepieceranges
• Catch ValueErrors in connect_to_tracker (to deal with invalid urls)

This is the second special experimental release with a new community called Noodle Community developed to test the effectiveness of our recent scientific work. We are testing the scalability of our integrated, distributed ledger. With your feedback and participation, we continuously improve the reliability of our community.

The research ideas from the lab for preventing information hiding and double-spending are stress tested. We dropped the global consensus part and also introduced controlled distributed coin minting. If this works, it offers full horizontal scalability.

This experimental release is based on the following fork:
