We expect this to be the last + alpha version of the 0.4.7.x series. Mostly minor bugfixes except one major + bugfix that changes how Tor behaves with DNS timeouts for Exit relays. As + always with an alpha, we recommend all relay operators to upgrade from + previous alpha to this one. + + o Major bugfixes (onion service, congestion control): + - Fix the onion service upload case where the congestion control + parameters were not added to the right object. Fixes bug 40586; + bugfix on 0.4.7.4-alpha. + + o Major bugfixes (relay, DNS): + - Lower the DNS timeout from 3 attempts at 5 seconds each to 2 + attempts at 1 seconds each. Two new consensus parameters were + added to control these values. This change should improve observed + performance under DNS load; see ticket for more details. Fixes bug + 40312; bugfix on 0.3.5.1-alpha. + + o Minor features (control port): + - Provide congestion control fields on CIRC_BW and STREAM control + port events, for use by sbws. Closes ticket 40568. + + o Minor features (fallbackdir): + - Regenerate fallback directories generated on March 25, 2022. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2022/03/25. + + o Minor bugfixes (DNSPort, dormant mode): + - A request on the DNSPort now wakes up a dormant tor. Fixes bug + 40577; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (metrics port, onion service): + - Fix the metrics with a port label to be unique. Before this, all + ports of an onion service would be on the same line which violates + the Prometheus rules of unique labels. Fixes bug 40581; bugfix + on 0.4.5.1-alpha. + + o Minor bugfixes (onion service congestion control): + - Avoid a non-fatal assertion failure in the case where we fail to + set up congestion control on a rendezvous circuit. This could + happen naturally if a cache entry expired at an unexpected time. + Fixes bug 40576; bugfix on 0.4.7.4-alpha. + + o Minor bugfixes (onion service, client): + - Fix a rare but fatal assertion failure due to a guard subsystem + recursion triggered by the onion service client. Fixes bug 40579; + bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (relay, overload): + - Decide whether to signal overload based on a fraction and + assessment period of ntor handshake drops. Previously, a single + drop could trigger an overload state, which caused many false + positives. Fixes bug 40560; bugfix on 0.4.7.1-alpha. + + Changes in version 0.4.7.4-alpha - 2022-02-25 This version contains the negotiation congestion control work which is the final part needed before going stable. There are also various bugfixes |
