tor 0.2.2.38 release notes list extra item

The release notes of 0.2.2.38 say, among other things:

  - Avoid read-from-freed-memory and double-free bugs that could occur
    when a DNS request fails while launching it. Fixes bug 6480;
    bugfix on 0.2.0.1-alpha.

However, that change was not part of 0.2.2.38, so the corresponding entry should be removed from changelog and release notes.
