+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).
