Another day, another build... Wink Check the changelog to see if anything is relevant to you.

Downloads: (if a link doesn't work, try another)
Alternate link: DD-WRT website
Note: to use wget (or curl) for CLI flash (`write {f/w} linux`), change the https to http (or use ftp instead)

SVN* changelog since last build: 39944
Summary: (deprecated after 29739)
*Github mirror:

1. SFE accelerated NAT is in 33006+ builds but only in kernel 3.2 and newer
2. 'KRACK' vulnerability fixes were completed in r33678 for Broadcom, including k26 (33655) & k24 (33656); use build 33772 or later.
3. Bridge modes on k4.4 devices may sometimes work in some configurations in certain builds but are not supported by the bcmdhd driver. Use client or repeater instead as WDS doesn't work with Broadcom ARM either (see Issues below).
4. Since 39469, udhcpd was removed and replaced with the already present dnsmasq, and PIE qdisc was added for some builds.
5. Policy-Based Routing with SFE enabled was fixed in r39556: 5986 and 5900
6. k2.4 (broadcom/) builds were fixed in 39715 (broken in 39144 through 39654)
7.SFE update (k3.10+ for BCM) was in the 39927 build.

Issues, observations, and/or workarounds reported:
1. Trendnet 81*DRU models are missing factory-to-flash
2. DNScrypt is mostly only using v2 protocols now, but requires Golang that DD can't use: 6246
3. WDS does not work on Broadcom ARM devices (only MIPS<->MIPS)
4. K2.6 builds are broken since 38253(?); GUI issues: 6538
5. VAPs not working at boot; workaround startup command:
sleep 10;stopservice nas;stopservice wlconf;startservice wlconf;startservice nas
This appears to be fixed for some routers (different kernels, modes, and radios) since build 39508.

Important: if any issues are found, please provide log info (GUI syslog, `dmesg`, `cat /var/log/messages`).
Or put into SVN ticket. For firewall issues, also provide "iptables" info (`iptables -L`, `iptables -t nat -L`, & the /tmp/.ipt file).

Template to copy (after "Code:") for posting issues, be sure to include the mode in use (gateway, AP, CB, etc.):
[b]Router/Version: [/b]
[b]File: [/b]
[b]Kernel: [/b]
[b]Mode: [/b]

I've ran this on my two E3000 and a E900 since it was posted on the ftp server, and so far, no issues. Speeds are great. Seems pretty stable. :3
