**Category:** Linux  
**Tags:** General  
**Published:** Thu, 17 Apr 2025 15:04:23 +0000  
**TL;DR:** Here is a 2-sentence summary:

The Tor Browser has released version 14.5, which includes the addition of Connection Assist on Android to help establish connections to the Tor network and language support for Belarusian, Bulgarian, and Portuguese. The Connection Assist feature was made possible after a multi-year effort to refactor tor integration across platforms, reaching an important milestone with its release on Android.  
<p><a href="https://blog.torproject.org/new-release-tor-browser-145/">Version
14.5</a> of the <a href="https://tb-manual.torproject.org/about/">Tor
Browser</a> has been released. Notable features in this release
include the addition of Connection Assist for the Android version of
the Tor Browser, and language support for Belarusian, Bulgarian, and
Portuguese for all versions of the browser.</p>

<blockquote class="bq">
Should Tor Browser fail to establish a direct connection to the Tor
network, Connection Assist will offer to find and try bridges for
you. But before this feature could be made available on Android, we
had to embark on a multi-year effort to refactor our tor integration
across each platform first. This project has now reached an important
milestone, and we're proud to announce the release of Connection
Assist for Android today.

**Tags:** Linux  
**Published:** Thu, 17 Apr 2025 14:23:45 +0000  
**TL;DR:** Here is a summary of the text in 2 sentences:

The kernel's memory controller enforces memory limits on groups of processes using the control-group mechanism, but it has historically had performance issues. To address this, experts like Shakeel Butt have been exploring ways to optimize the memory controller at Linux summits, such as the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit.  
The kernel's memory controller works within the control-group mechanism to
enforce memory-usage limits on groups of processes.  This component has
often had performance problems, so there is continual interest in
optimizing it.  Shakeel Butt led a session during the memory-management
track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF
Summit to look at the current state of the memory controller and what can
be done to reduce its overhead.
