What's new in 6.0rc3 (2012-Nov-09 12:59): *) fixed problem - MetaROUTERs did not work on RB2011s; *) fixed problem - Realtek 1Gbit ethernet cards did not work; *) added "/ip settings" menu with following settings: ip-forward, send-redirects, accept-source-route, accept-redirects, secure-redirects, rp-filter, tcp-syncookies; *) fix some ipv6 firewall matchers; *) improved performance for eoip,eoipv6,gre,gre6 tunnels, especially on multi core; *) /queue tree entries with parent=global are performed separately from /queue simple and before /queue simple; *) snmp - fixed missing OIDs; Caveat: MetaROUTERs do not work on PowerPC routerboards; What's new in 6.0rc2 (2012-Oct-24 11:27): *) added generic fast path support on certain interfaces (all ethernets on RB3xx, RB6xx, RB7xx, RB8xx, RB9xx, RB1000, RB11xx, RB2011); *) added ipv4 fast path, it doubles ipv4 forwarding performance on supported interfaces when no firewall, conntrack, queues. *) added traffic generator fast path; *) addedbridge fast path; More info on fast path: http://wiki.mikrotik.com/wiki/Manual:Fast_Path What's new in 6.0rc1 (2012-Sep-26 14:56): *) i386 - increased number of supported cores to 64; *) userman - fix unpaid profile activation while authenticating; *) dhcp client - custom options; *) dhcp options - allow mixing different data types; *) console - "export compact" now is the default, use "export verbose" to get previous behaviour; *) ntp - make it work again; *) tftpd - if real-file is a existing directory then prefix request with it; *) RB333 ethernets are back; *) dns - rotate servers only on failure; *) fix M3P (/ip packing); What's new in 6.0beta3 (2012-Aug-22 12:12): *) installation - use much less space in storage (works well with 32MiB flash); *) routerboard package is now merged with system package; *) userman - use corresponding time zone data when showing date in console; *) gps - init-string option; *) ipsec - kill phase1 if ipsec-sa in responder expires due to system time change; *) ipsec - rekey phase1 before expiration; *) ipsec - when last ISAKMP-SA is deleted for the remote host remove related IPSec-SAs; *) ipsec - send delete IPSec-SAs on shutdown/reboot; *) user manager - fix user's active profile end time if it has unlimited validity, these users now won't be hidden from reports when date filters are in effect; *) certificate validity is shown using local timezone offset; *) fixed queue bit rate reporting; *) fixed ipv6 firewall; *) upgraded drivers and kernel (to linux-3.3.5); *) added priority matcher to firewall; *) added change-dscp from-priority and from-priority-to-high-3-bits options; *) fixed router crash or hang when rebooting; *) add snif-tzsp,snif-pc actions to ip/ipv6 firewall mangle; *) traffic-generator improvements for multi core; What's new in 6.0beta2 (2012-Apr-24 10:57): *) "/ip address set" and "/ipv6 address set" commands did not work properly; (2012-apr-16 14:26): *) fix eoipv6 tunnels, tunnel-ids in packets were shuffled; *) fix dynamic simple queues; *) fix /ipv6 firewall connection-state matcher, was crashing router; *) fix traffic generator, was crashing router when generating traffic on bonding interface; *) fix wds interfaces; *) downgrading to v5 was losing wireless interface configuration; *) fix queue byte and rate statistics; *) fix ethernet port order on all boards; What's new in 6.0beta1 (2012-Apr-13 15:26): *) updated drivers and kernel (to linux-2.6.38.2); *) improved interface management (scales well for up to thousands of interfaces and more); *) improved queue management (/queue simple and /queue tree) - easily handles tens of thousands of queues; *) improved overall router performance when simple queues are used - at least double the performance of v5, even bigger improvements on multicore systems; *) very small overhead for packets that miss simple queues, but simple queues are present in the system; *) pcq queue is NAT aware (just like "/queue simple" and "/ip traffic-flow"; *) in "/ip firewall mangle" can specify "new-priority=from-dscp-high-3-bits"; *) new default queue types: pcq-download-default and pcq-upload-default; *) simple queues have separate priority setting for download/upload/total; *) slave flag shows up for interfaces that are in bridge,bonding or switch group; *) global-in, global-out, global-total parent in /queue tree is replaced with global that is equivalent to global-total in v5; *) simple queues happen in different place - at the very end of postrouting and local-in chains; *) simple queues target-addresses and interface parameters are joined into one target parameter, now supports multiple interfaces match for one queue; *) simple queues dst-address parameter is changed to dst and now supports destination interface matching; *) dns cache logs requests to topics "dns" and "packet";
