+yaSSL Release notes, version 2.3.9 (12/01/2015)
+    This release of yaSSL fixes two client side Diffie-Hellman problems.
+    yaSSL was only handling the cases of zero or one leading zeros for the key
+    agreement instead of potentially any number.  This caused about 1 in 50,000
+    connections to fail when using DHE cipher suites.  The second problem was
+    the case where a server would send a public value shorter than the prime
+    value, causing about 1 in 128 client connections to fail, and also
+    caused the yaSSL client to read off the end of memory.  All client side
+    DHE cipher suite users should update.
+    Thanks to Adam Langely (agl@imperialviolet.org) for the detailed report!

 yaSSL Release notes, version 2.3.8 (9/17/2015)

+# Bug#21205695 DROP TABLE MAY CAUSE SLAVES TO BREAK
+#
+# Problem:
+# ========
+# 1) Drop table queries are re-generated by server
+#    before writing the events(queries) into binlog
+#    for various reasons. If table name/db name contains
+#    a non regular characters (like latin characters),
+#    the generated query is wrong. Hence it breaks the
+#    replication.
+# 2) In the edge case, when table name contains
+#    64 latin characters (latin takes 2 bytes), server is
+#    throwing an assert (M_TBLLEN < 128)
+#
+# 3) In the edge case, when db name contains 64 latin
+#    characters, binlog contents are interpreted wrongly
+#    which is leading to replication issues.

+# Bug#17047208 REPLICATION DIFFERENCE FOR MULTIPLE TRIGGERS
+# Problem: If DML invokes a trigger or a stored function that inserts into an
+# AUTO_INCREMENT column, that DML has to be marked as 'unsafe' statement. If the

+# TABLES), then the DML statement is not marked as 'unsafe' statement.
+
+# Steps to reproduce the reported test case (BINLOG_STMT_UNSAFE_AUTOINC_COLUMNS)
+# Case-1:
+#  > Create a trigger on a table and do a insert in the trigger that updates
+#     auto increment column
+#  > A DML that executes the trigger in step.1 and check that DML is marked
+#     as unsafe and DML is written into binlog using row format (in MBR)
+#  > Execute the step 2 by locking the required tables prior to DML and check
+#     that DML is marked as unsafe and DML is written into binlog using row
+#     format (in MBR)
+#
+#  This test script also adds test cases to cover few other unsafe statements.
