+ Don't report 5005 (DIAMETER_AVP_MISSING) errors
+ unnecessarily.</p>
+ <p>
+ An AVP whose decode failed was reported as missing,
+ despite having been reported with another error as a
+ consequence of the failure.</p>

+ Improve decode performance.</p>
+ <p>
+ The time required to decode a message increased
+ quadratically with the number of AVPs in the worst case,
+ leading to extremely long execution times.</p>

+ Improve watchdog and statistics performance.</p>
+ <p>
+ Inefficient use of timers contributed to poor performance
+ at high load, as did ordering of the table statistics are
+ written to.</p>

+ <p>
+ Add service_opt() strict_mbit.</p>
+ <p>
+ There are differing opinions on whether or not reception
+ of an arbitrary AVP setting the M-bit is an error. The
+ default interpretation is strict: if a command grammar
+ doesn't explicitly allow an AVP setting the M-bit then
+ reception of such an AVP is regarded as an error. Setting
+ <c>{strict_mbit, false}</c> disables this check.</p>
