Changes since 1.9.52:
### BUGFIXES
+ Bugfix: do not re-authenticate if server requires authentication for the
  same command twice - to avoid an unterminated re-authentication loop.
+ Bugfix: Various error conditions now cause the problem to be logged.
+ Bugfix: Newly-added groups that are not in a server no longer cause
  fetchnews to proceed to the next server.
+ Bugfix: texpire did not repair the spool in archived groups
  (groupexpire some.news.group = -1) which caused duplicates and articles
  inaccessible by Message-ID after corruption. Reported by Dirk-Lüder Kreie.
+ Portability: One string was split for C89 conformance (string constants
  cannot exceed 509 characters).

### CHANGES
+ Feature: fetchnews supports an environment variable, LN_SKIP_GROUPS, that is
  treated as a comma-separated list of wildmats, any match sufficient. All
  matching groups are skipped, so you can skip your binary groups during
  daytime, for instance. Don Geddis had complained a configuration cheat he'd
  been using had stopped working with one of the recent fixes. Let there be an
  official way to do things instead.
+ Feature: The time zone is back in leafnode-generated Date: headers, provided
  that the operating system provides a tm_gmtoff member in struct tm (BSD,
  GNU). Systems that don't offer this use GMT and report the time zone as
  -0000.
+ Feature: The environment variable LN_DEBUG is now read as an integer. The
  debug level is the greater of debugmode in the config file and the contents
  of LN_DEBUG.
+ Compatibility: support forgetful servers that require re-authentication
  often. Reported by Andrew Cranson.
+ Consistency: the try_lock() debug message now goes to stdout, and only in
  verbose mode. It used to be printed on stderr, unlike most of the other
  debug messages. Reported by Kieron Dunbar.
+ Consistency: "skipped group.name, not in only_groups_pcre" message is now
  prefixed with the server name.
+ Documentation: If the volunteered authentication early in a connection
  fails, add a log that this condition may have been caused by premature
  authentication.
  NOTE: authentication implementations differ a lot.
+ Documentation: The server= examples in config.example were revised and are
  now G-rated and end in domains that are guaranteed to not exist.
