+  o Major bugfixes (v3 onion services):
     - Make onion service always use the exact amount of configured intro
       points (or less due to node exlusion). Before, a service could
       sometimes pick more intro points than configured with the
       HiddenServiceNumIntroductionPoints option. Fixes bug 31548; bugfix
       on 0.3.2.1-alpha.

     - The ADD_ONION key blob keyword "BEST" now defaults from RSA1024

       libc name lookup functions with ones that do not actually touch
