+* Repair --user, broken in 6.3.5 (as a side effect of the authenticate external
+ patch): using SSL certificate/key authentication overrode the --user option.
+ Now the latter takes precedence, and only defaults to the certificate's common
+ name. Debian Bug #400950, reported by Jorgen Schaefer <forcer@debian.org>.
+
+# BUG FIXES (long-standing bugs):
+* RPOP: used to log the password locally rather than an asterisk as the other
+ protocols do. The password is now shrouded in the local logs.
+* POP3: Probes capabilities now when Kerberos V5 is enabled, so that we can
+ actually detect if the server supports it.
+* Robustness: If a stale lockfile cannot be deleted, truncate it so that
+ fetchmail doesn't later believe itself to be running if the PID is recycled
+ by a non-fetchmail process.
+* DNS: Detect /etc/resolv.conf changes: On systems that have res_search(),
+ assume we also have res_init() and call it (suggested by Ulrich Drepper,
+ glibc bug #3675) in order to make libc or libresolv reread the resolver
+ configuration at the beginning of a poll cycle. This is important when
+ fetchmail is in daemon mode and /etc/resolv.conf is changed later by dhcpcd,
+ dhclient, pppd, openvpn or other ip-up/ipchange scripts. Should fix Debian
+ Bug#389270, Bug#391698.
+* Robustness: Fix crash on systems that do not provide strdup(), the crash
+ happens only in out-of-memory conditions when fetchmail cannot proceed
+ anyways. Patch by Andreas Krennmair.
+* Robustness: When HOME and FETCHMAILHOME are unset, be sure to copy user
+ database information, so it is not trashed later. Patch by Jim Correia.
+
+# CHANGES:
+* Workaround: Improve handling of IMAP IDLE, some servers do not reset their
+ time counters after sending information asynchronously. Patch by Sunil
+ Shetye, after report from Andrew Baumann.
+* Usability: When requesting Kerberos or GSSAPI, complain and exit with syntax
+ error if any of these requested features has not been compiled in. This is
+ to fail early and with precise error message. Reported by Isaac Wilcox.
+* --version will now add +KRB4 or +KRB5 if Kerberos v4 or v5, respectively, have
+ been compiled in. Reported missing by Isaac Wilcox.
