What's new in 3.0rc7:

*) ftpd - automatically reboot after finishing upload that has name *.auto.npk;
*) added support for Sierra Wireless AirCard 595U;
*) ping - show more types of ICMP reply messages, like in 2.9 versions;
*) add ICMP MPLS extension support to traceroute;
*) console detects terminal size and capabilities, TERM environment
variable is not used, so now this works even over serial;
*) console - fixed crash on non-ASCII characters in input and output;
*) console - export correctly strings that contain control characters;
*) fixed in console - when argument value evaluation produces error, report
that error instead of "invalid value for ..." message;
*) console - changed the way how required command arguments are processed,
now commands like "enable [find]" don't fail with error when find returns
nothing;
*) fixed memory leak on RB500;
*) fixed layer7 protocol matcher, did not handle \x.. sequences correctly;
*) fixed allow-shared-key mode for wireless;
*) fixed station-pseudobridge mode when used in combination with
nstreme framer-policy;
*) fixed hidden ssid issues with wds links;
*) SNTP client - adjust DST according to timezone settings when clock changes;
*) console - fixed crash when terminal size is extremely small (like 1x1),
assume default width 80 if terminal is too narrow;
*) SNTP - fixed overflow bug, now clocks are adjusted correctly if initial
time is way back (like jan/01/1970 on routerboards);
*) added RIPng support in WinBox;
*) added BGP for IPv6 support in WinBox;
*) added PIM support in WinBox;
*) added hide passwords option to WinBox;
*) added regular expression matching to dns resolver static entries;
*) user manager - fixed bug for credit extension using PayPal payments;

595U works perfectly!

is it possible to use it on other sierra card type?
