Facility for named queues: A commandline argument can specify + the queue name for a queue operation, and an ACL modifier can set + the queue to be used for a message.

LMDB lookup support, as Experimental. Patch supplied by Andrew Colin Kissa. + + 9. Expansion operator escape8bit, like escape but not touching newline etc.. + +10. Feature macros, generated from compile options. All start with "_HAVE_" + and go on with some roughly recognisable name. Driver macros, for + router, transport and authentication drivers; names starting with "_DRVR_". + Option macros, for each configuration-file option; all start with "_OPT_". + Use the "-bP macros" command-line option to see what is present. + +11. Integer values for options can take a "G" multiplier. + +12. defer=pass option for the ACL control cutthrough_delivery, to reflect 4xx + returns from the target back to the initiator, rather than spooling the + message. + +13.

Expansion operators ${ipv6norm:} and ${ipv6denorm:}. + The latter expands to a 8-element colon-sep set of hex digits including + leading zeroes. A trailing ipv4-style dotted-decimal set is converted + to hex. Pure ipv4 addresses are converted to IPv4-mapped IPv6. + The former operator strips leading zeroes and collapses the longest + set of 0-groups to a double-colon. + + 5.
