Is it possible that simple queues and queue tree work together? I mean address list/mangle/queue tree?

If you have simple queues and queue tree in the same HTB - simple queues will get traffic first.

What's new in 3.18:

*) IPv6 address auto-configuration: added recursive DNS server option;
*) fixed problem - sometimes firewall did not work after reboot on RB1xx;
*) do not send IPv6 packets over PPTP, L2TP or PPPoE - could confuse some
servers or clients;
*) allow queues to have all traffic, not only ip (for example vpn);
*) added ability to specify dns name in bandwidth test in WinBox;
*) fixed problem - sometimes RB1xx (and RB4xx) could not start up or startup was very long;
*) improved ipv6 sniffing;
*) improve torch and sniffer behavior under high load;
*) improved queue statistics;
*) fix xen make-routeros-image command;
*) fix potential wireless crash under load when negotiating encryption;
*) fix several MPLS issues in mpls-test;
*) fixed support for Novatel Wireless Ovation MC950D HSUPA;
*) fixed some bugs in routing-test OSPF;
*) added support for D-Link DUB-E100 USB Ethernet adapter;
*) fixed user-manager database rebuild command to succeed in case of
malformed database disk image;
*) sms - added descriptions for error codes;
*) sms - added automatic 'smsc' (service centre address) value detection,
to work around first time error when sending SMS without specifying
an 'smsc' value;
*) fixed - during uptime 4:20 .. 5:00 interface traffic (byte and packet
count) was being reported 100 times larger than the actual value;
*) provide L2TP server address in Called-Station-Id when doing authentication over RADIUS;
*) added support for Sierra Wireless MC8790;
*) recalibrated noise floor adjustment for R5H;
*) updated drivers & kernel - fixed fast clock issue on x86;

What's new in 3.19:

*) fixed problem - web proxy used up all router memory
if unlimited ram caching was enabled;
*) fixed problem - some log topics got swapped in configuration;
*) reduced maximum supported memory for RB1000 to 1.5Gb (was 1.75Gb);
*) interface mesh was not working in 3.18, fixed;
*) fixed Prism crash;
*) fixed VPLS interface related crash in mpls-test;
*) allow to enter range in BGP instance confederation peers;
*) console - fixed '/system backup save' command, name argument is
optional, and backup file name is automatically generated if empty;
*) sped up IPv6 forwarding on RB4xx, RB1xx and RB5xx;
*) fixed BGP route selection in routing-test;
*) fixed dhcp server to update agent-circuit-id and agent-remote-id for lease
whenever it changes;
