What's new in 6.44rc1 (2019-Feb-15 07:12):

Important note!!! Backup before upgrade!
Due to major IPsec configuration changes in RouterOS v6.44beta39+ (see changelog below), it is advised to make a backup before upgrading. Regular downgrade will still be possible as long as no changes in IPsec peer menu are done.

MAJOR CHANGES IN v6.44:
----------------------
!) cloud - added command "/system backup cloud" for backup storing on cloud (CLI only);
!) ipsec - added new "identity" menu with common peer distinguishers;
!) ipsec - removed "main-l2tp" exchange-mode, it is the same as "main" exchange-mode;
!) ipsec - removed "users" menu, XAuth user configuration is now handled by "identity" menu;
!) radius - initial implementation of RadSec (Radius communication over TLS);
!) speedtest - added "/tool speed-test" for ping latency, jitter, loss and TCP and UDP download, upload speed measurements (CLI only);
!) telnet - do not allow to set "tracefile" parameter;
!) upgrade - release channels renamed - "bugfix" to "long-term", "current" to "stable" and "release candidate" to "testing";
!) upgrade - "testing" release channel now can contain "beta" together with "release-candidate" versions;
