Changes in version 0.4.7.1-alpha - 2021-09-17
This version is the first alpha release of the 0.4.7.x series. One major
feature is Vanguards Lite, from proposal 333, to help mitigate guard

This version is the first alpha release of the 0.4.7.x series. One
major feature is Vanguards Lite, from proposal 333, to help mitigate
guard discovery attacks against onion services. It also includes
numerous bugfixes.
o Major features (Proposal 332, onion services, guard selection algorithm):
- Clients and onion services now choose four long-lived "layer 2"
guard relays for use as the middle hop in all onion circuits.
These relays are kept in place for a randomized duration averaging
1 week. This mitigates guard discovery attacks against
clients and short-lived onion services such as OnionShare. Long-
lived onion services that need high security should still use the
Vanguards addon (https://github.com/mikeperry-tor/vanguards).
Closes ticket 40363; implements proposal 333.

immediately from startup. Previously, they waited until they had
been running for a full day. Closes ticket 40337.
o Minor bugfixes (onion service):
- Do not flag an HSDir as non-running in case the descriptor upload
or fetch fails. An onion service closes pending directory
connections before uploading a new descriptor which leads to
wrongly flagging many relays and thus affecting circuit path
selection. Fixes bug 40434; bugfix on 0.2.0.13-alpha.
o Minor bugfixes (circuit padding):
- Don't send STOP circuit padding cells when the other side has
already shut down the corresponding padding machine. Fixes bug
