There's now a php enabled module for rapid updating.
There's now a dark theme that is enabled by default
Responsive buttons are enabled by default.
Clearing the stats have recently been added for people running lighttpd
When I enabled lighttpd on the dd-wrt GUI it shows this:
HTTPS Port: 443
HTTP Port: 8000
As per instruction 3 I changed http port to 81. When I now visit http://192.168.1.1:8000/bwmon.html I get the page but there are no entries on the page. I see the title row of the table, plus the Totals row, and in the middle an asterisk * row with "0B" as values. I did see one of my devices appear temporarily with 0 values, but it disappeared again.
By the way - for anyone that is having difficulty mounting the USB drive - the dd-wrt GUI asks for the UUID of the drive. When you first enable USB and plug it in, you will see the UUID displayed - copy the UUID into the /jffs field as per the screenshot attached.
There have been numerous smaller updates recently the current version is 2.2.0.
It's now got a dark theme and rudimentary password protection. Your password isn't stored just a hash on the router and that's what's verified through the browser. You must set this password on the command line.
This was a much requested feature.
It should be compatible with the latest DDWRT beta currently 42681 however I don't have a large selection of routers to test so we'll have to deal with bugs as they come.
Now that a lot of us will be working from home this should be useful in diagnosing intermittent networking troubles.
