release: ChangeLog and ReleaseNotes for 0.4.7.15

Changes in version 0.4.7.15 - 2023-09-18

  This version contains an important fix for onion service regarding congestion

  control and its reliability. Apart from that, very minor bugfixes. We

  strongly recommend all onion service operators to update immediately.

  o Major bugfixes (onion service):

    - Fix a reliability issue where services were expiring their

      introduction points every consensus update. This caused

      connectivity issues for clients caching the old descriptor and

      intro points. Bug reported and fixed by gitlab user

      @hyunsoo.kim676. Fixes bug 40858; bugfix on 0.4.7.5-alpha.

  o Minor features (fallbackdir):

    - Regenerate fallback directories generated on September 18, 2023.

  o Minor features (geoip data):

    - Update the geoip files to match the IPFire Location Database, as

      retrieved on 2023/09/18.

  o Minor features (testing):

    - Enable Doxygen and Stem tests for 0.4.8 and clean-up some logic

      for handling versions of Tor that are no longer supported. Closes

      ticket 40859.

  o Minor bugfixes (compression):

    - Right after compression/decompression work is done, check for

      errors. Before this, we would consider compression bomb before

      that and then looking for errors leading to false positive on that

      log warning. Fixes bug 40739; bugfix on 0.3.5.1-alpha. Patch

      by "cypherpunks".

  o Minor bugfixes (compression, zstd):

    - Use less frightening language and lower the log-level of our run-

      time ABI compatibility check message in our Zstd compression

      subsystem. Fixes bug 40815; bugfix on 0.4.3.1-alpha.

Changes in version 0.4.7.14 - 2023-07-26

  This version contains several minor fixes and one major bugfix affecting

  vanguards (onion service). As usual, we recommend upgrading to this version

release of Tor. If you want to see more detailed descriptions of the
