RouterOSのCurrentブランチがマイナーアップデートされました。

今回は10日間ほどでアップデートされましたが、更新内容は多めです。

What's new in 6.37.2 (2016-Nov-08 13:15):

Important note!!!
Dude client auto-upgrade to this version will not work. Use http://www.mikrotik.com/download for 6.37.2 client download/install.
It will be fixed in soon to be released v6.37.3 

Changes since 6.37.1:

!) ethernet - optimized packet processing on low load when irq re-balance is not necessary;
!) fastpath - let one packet per second through slow path to properly update connection timeouts;
!) queues - significantly improved hashing algorithm in dynamic simple queue setups (fixes CPU load spikes on queue removal);
*) arm - improved watchdog reliability;
*) bonding - fixed 802.3ad load balancing over routed VLANs with fastpath enabled;
*) bonding - fixed mac address selection after upgrade;
*) crs - fixed port mirroring halt after L2MTU change;
*) dhcp - do not allow to create dhcp-server on slave interface;
*) ethernet - fixed interface speed reporting for x86 in log after reboot or if "disable-running-check=yes";
*) ethernet - fixed potential loopprotect crash;
*) export - fixed "/interface ethernet switch export" on some boards;
*) export - fixed CRS switch egress-vlan-tag export;
*) fastpath - fixed kernel failure when fastpath traffic goes into loop;
*) fastpath - improved connection tracking timeout updates;
*) firewall - do not allow to increase/decrease ttl and hop-limit by 0;
*) firewall - fixed "connection-state" value disappearance in rules that were created before v6.22;
*) firewall - fixed compact export (introduced in 6.37rc14);
*) firewall - improved "time" option (ranges like 22h-10h now are acceptable);
*) hotspot - fixed nat rule dst-port by making it visible again for Walled Garden ip return rules;
*) ipsec - changed logging topic from error to debug for ph2 transform mismatch messages;
*) ipv6 - increased default max-neighbor-entries value to 8192, same as ipv4;
*) mmips - improved watchdog reliability;
*) package - show minimal supported RouterOS version under "/system resource" menu if it is specified;
*) queue - fixed rare crash on statistic gathering in "/queue tree";
*) queue - improved "time" option (ranges like 22h-10h are now usable);
*) rb2011 - fixed crash on l2mtu changes;
*) sms - fixed crash after modem has failed to start;
*) ssl - fixed potential memory leak ( when using dude for example);
*) torch - fixed aggregate statistics appearance;
*) traffic-flow - fixed dst-port reporting if connection is not maintained by connection tracking;
*) userman - fixed memory leak on user limitation calculations;
*) winbox - added led settings menu;
*) winbox - fixed missing switch menu for mmips devices;

Important Noteとあるように、Dude ClientのAuto-updateが動作しないようです。これについてはRouterOS 6.37.3で修正されるとのことです。

他にも、ethernet – optimized packet processing on low load when irq re-balance is not necessary;とあるように、irqbalanceの再調整が行われたようで、負荷が低減したとのことです。以前よりも高負荷に耐えるようになったのではないでしょうか。

Changelogには書かれていませんが、たぶん安定性の向上も図られたと思うので、Currentブランチということを理解できる人は適用してみてはいかがでしょうか。

今のところ筆者の環境においては、Tile、mips、ARMでは大きなトラブルは出ていません。
