Remove changes files for things that went out in 0.4.5.2-alpha or earlier

changes/bug30187

-  o Major bugfixes (relay, windows):
-    - Fix bug where running a relay on Windows would use 100%
-      CPU after some time. Makes Windows >= Vista the required
-      Windows version to build and run tor. Fixes bug 30187;
-      bugfix on 0.4.5.1-alpha. Patch by Daniel Pinto.

changes/bug32880

-  o Minor bugfixes (circuit, handshake):
-    - In the v3 handshaking code, Use connection_or_change_state() to change
-      the state. Previously, we changed the state directly, but this did not
-      pass a state change to the pubsub or channel object. Fixes bug 32880;
-      bugfix on 0.2.3.6-alpha. Patch by Neel Chauhan.

changes/bug40015

-  o Major bugfixes (crash, relay, signing key):
-    - Avoid asserts when we run Tor from the command line with
-      `--key-expiration sign` when an ORPort is not set. Fixes
-      bug 40015; bugfix on 0.3.2.1-alpha. Patch by Neel Chauhan.

changes/bug40017

-  o Minor features (protocol, proxy support, defense in depth):
-    - Respond more deliberately to misbehaving proxies that leave leftover
-      data on their connections, so as to be even less likely as to allow
-      them to pass their data off as having come from a relay.
-      Closes ticket 40017.

changes/bug40172

-  o Minor bugfixes (compilation):
-    - Fix a compilation issue in which the correct 'ranlib' program was not
-      used when building libtor.a.  Fixes bug 40172; bugfix on 0.4.5.1-alpha.

changes/bug40177

-  o Minor bugfixes (compilation):
-    - Remove a duplicate typedef in metrics_store.c.  Fixes bug 40177;
-      bugfix on 0.4.5.1-alpha.

changes/bug40179_part1

-  o Minor bugfixes (testing, portability):
-    - Fix our Python reference-implementation for the v3 onion service
-      handshake so that it works correctly with the version of hashlib provided
-      by Python 3.9. Fixes part of bug 40179; bugfix on 0.3.1.6-rc.

changes/bug40179_part2

-  o Minor bugfixes (testing):
-    - Fix the config/parse_tcp_proxy_line test so that it works correctly on
-      systems where the DNS provider hijacks invalid queries.
-      Fixes part of bug 40179; bugfix on 0.4.3.1-alpha.

changes/bug40187

-  o Minor bugfixes (testing):
-    - Fix unit tests that used newly generated list of routers so that they
-      check them with respect to the date when they were generated, not
-      with respect to the current time.  Fixes bug 40187; bugfix on
-      0.4.5.1-alpha.

changes/ticket18888

-  o Minor features (safety):
-    - Log a warning at startup if Tor is built with compile-time options that
-      are likely to make it less stable or reliable. Closes ticket 18888.

changes/ticket22473

-  o Removed features (controller):
-    - Remove the "GETINFO network-status" controller command. It has
-      been deprecated since 0.3.1.1-alpha.  Closes ticket 22473.

changes/ticket25528

-  o Minor bugfixes (client, bridge, configuration):
-    - Exit tor on a misconfiguration when the Bridge line has a transport but
-      no corresponding ClientTransportPlugin can be found. Prior to this fix,
-      tor would attempt to connect to the bridge directly without using the
-      transport leading to a possible leak on the wire. Fixes bug 25528;
-      bugfix on 0.2.6.1-alpha.

changes/ticket32178

-  o Minor bugfixes (logging):
-    - Remove trailing whitespaces from control event log messages. Fixes bug
-      32178; bugfix on 0.1.1.1-alpha. Based on a patch by Amadeusz Pawlik.

changes/ticket40071

-  o Minor bugfixes (relay, address):
-    - Don't trigger an IP change if no new valid IP can be found. Fixes bug
-      40071; bugfix on 0.4.5.1-alpha.
-    - When attempting to discover our IP, don't launch a descriptor fetch
-      anymore but rather a simple test circuit since the address discovery is
-      through the NETINFO cell now from the authorities. Fixes bug 40071; bugfix
-      on 0.4.5.1-alpha.

changes/ticket40142

-  o Minor bugfixes (logging, flow control):
-    - Turn a SENDME failure log warning into a debug. It can actually happen
-      naturally. Fixes bug 40142; bugfix on 0.4.1.1-alpha.

changes/ticket40165

-  o Minor features (compilation):
-    - Disable deprecation warnings when building with OpenSSL 3.0.0 or later.
-      There are a number of newly deprecated APIs in OpenSSL 3.0.0 that Tor
-      still requires.  (A later version of Tor will try to stop depending on
-      these.)  Closes ticket 40165.

changes/ticket40170

-  o Minor bugfixes (tests):
-    - Fix the "tortls/openssl/log_one_error" test to work with OpenSSL 3.0.0.
-      Fixes bug 40170; bugfix on 0.2.8.1-alpha.

changes/ticket40174

-  o Minor bugfixes (configure, build):
-    - With USDT tracing enabled, if STAP_PROBEV() is missing, don't attempt to
-      build. Linux supports that macro but not the BSDs. Fixes bug 40174; bugfix
-      on 0.4.5.1-alpha.

changes/ticket40183

-  o Minor bugfixes (port configuration):
-    - Second non ORPort of a different family (ex: SocksPort [::1]:9050) was
-      ignored due to a logical configuration parsing error. Fixes bug 40183;
-      bugfix on 0.4.5.1-alpha.

changes/ticket40195

-  o Minor bugfixes (configuration, ports):
-    - Fix an issue where an ORPort was validated against other type of ports
-      when it should have been only checked against other ORPorts. This lead to
-      "DirPort auto" to be ignored and failing to be used. Fixes bug 40195;
-      bugfix on 0.4.5.1-alpha.
