+46. Reset the locale to "C" after calling embedded Perl, in case it was changed
+ (this can affect the format of dates).
+
+47. exim_tidydb, when checking for the continued existence of a message for
+ which it has found a message-specific retry record, was not finding
+ messages that were in split spool directories. Consequently, it was
+ deleting retry records that should have stayed in existence.
+
+48. Steve fixed some bugs in eximstats.
+
+49. The SPA authentication driver was not abandoning authentication and moving
+ on to the next authenticator when an expansion was forced to fail,
+ contradicting the general specification for all authenticators. Instead it
+ was generating a temporary error. It now behaves as specified.
+
+50. The default ordering of permitted cipher suites for GnuTLS was pessimal
+ (the order specifies the preference for clients). The order is now AES256,
+ AES128, 3DES, ARCFOUR128.
+
+51. Small patch to Sieve code - explicitly set From: when generating an
+ autoreply.
+
+52. Exim crashed if a remote delivery caused a very long error message to be
+ recorded - for instance if somebody sent an entire SpamAssassin report back
+ as a large number of 550 error lines. This bug was coincidentally fixed by
+ increasing the size of one of Exim's internal buffers (big_buffer) that
+ happened as part of the Exiscan merge. However, to be on the safe side, I
+ have made the code more robust (and fixed the comments that describe what
+ is going on).
+
+53. Now that there can be additional text after "Completed" in log lines (if
+ the queue_time_overall log selector is set), a one-byte patch to exigrep
+ was needed to allow it to recognize "Completed" as not the last thing in
+ the line.
