V7.6.0

This is the first release of the Tribler 7.6 series. It includes many tweaks and extensive Channels GUI changes. Most notable changes:

• Refactored Channels GUI
• Fixed slow channel processing - channels processing speed increased 10x-100x times
• Added Sentry crash report processing
• Removed TrustChain in favour of our new LedgerZero traffic accounting system
• Increased Tunnels performance due to refactored IPv8 serializer
• Completely removed VLC and its dependencies
• Many smaller bug fixes and performance improvements

ATTENTION:

1. This release features an upgrade of the Channels database. The migration can take quite some time. To greatly speed up the upgrade process, close all other programs before running 7.6.0 for the first time.
2. We disabled the token balance indicator for this release, as the new accounting system is not stable enough for production use yet. We will re-enable it in later releases.
3. This release fixes the insta-crash bug affecting Tribler 7.5.4. Every user of 7.5.4 is advised to upgrade to 7.6.0 immediately.

V7.5.1

This minor release fixes a bug where Tribler would crash or refuse to start when logging non-UTF8 characters.

Changelog:

• Fixed a bug where Tribler would crash or not startup when logging non-UTF8 characters.

V7.5.0

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.

V7.5.0-rc6

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