Change log below. While a "#" comment can't be placed directly at the end of a command, a semicolon does end a command, so a comment at the end of a line, preceded by a ";" works! Unlike my previous upgrade from v6.10 to v6.12, which reduced my dBm levels by 5 dB (even after a firmware downgrade) until I reset the configuration, this upgrade has made no difference in the dBm levels. What's new in 6.13 (2014-May-15 16:03): *) console - comments are now accepted where new command can start, that is, where '/' or ':' characters can be used to start new command, e.g. /interface { # comment until the end of the line print } *) backup - backups by default are encrypted now (with user password). To use backup on older versions, you should disable encryption with dont-encrypt flag when creating it; *) files with '.sensitive.' in the filename require 'sensitive' permission to manipulate; *) lcd - reduce CPU usage when displaying static screens; *) l2tp - fixed occasional server lockup; *) pptp - fixed memory leak; *) sstp - fixed crashes;
