After months of work, we have a new stable release: Tor 0.4.0.5. It contains improvements for power management and bootstrap reporting, as well as preliminary backend support for circuit padding to prevent some kinds of traffic analysis.
🔋 New major feature: When Tor is running as a client, and it is unused for a long time, it can now enter a "dormant" state. When Tor is dormant, it avoids network and CPU activity until it is re-awoken either by a user request or by a controller command. https://blog.torproject.org/new-release-tor-0405
