WARNING: DO NOT flash this experimental test build unless you know the risks and recovery methods. Report here to provide important info for developers and users. Always state your hardware model & version, mode (e.g. Repeater) and SPECIFIC build (e.g. netgear-r7000-webflash). Avoid discussions and create a new thread for specific problems or questions as this thread is not for support, and posts may be deleted or moved.

Changelogs:
SVN* changelog since last build: 42287
Summary: (deprecated after 29739)
*Github mirror: https://github.com/mirror/dd-wrt/

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

Issues, observations, and/or workarounds reported:
1. DNScrypt is mostly only using v2 protocols now, but requires Golang that DD can't use: 6246
2. WDS does not work on Broadcom ARM devices (only MIPS<->MIPS)
3. VAPs not working at boot fixed for unbridged VAPs with r40564:40566. Workaround startup command:
sleep 10;stopservice nas;stopservice wlconf;startservice wlconf;startservice nas (there are a few alternatives to search)

Notes:
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 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. PBR/UDP with SFE working again since r40513 (see 6729)
5. CAKE scheduler changes "completed" with r41057 (see 5796) & FQ_CODEL_FAST with r41027 (reset first!)
6. Reset button was broken in 40571; fixed in build 40750.
7. Radio Timer / GTK Renewal issues, syslog spam and wireless issues (BCM MIPS) fixed with r41662
8. New Broadcom build option for 8MB+ K2.x devices (limited currently):
broadcom_K3X_mipsel32r1 [BS has tested on a WRT600N v1.1]
9. CVE-2019-14899 VPN fix (r41784: applicability depends on VPN setup) and GUI toggle (r41812): ticket 6920, 6928, 6931, 6932
10. In-kernel samba now used and default min/max versions have changed, so change them if needed: 6954, 6957

Router is updated via ssh. After install and reboot I have small problem with GUI. I need minor changes (change mac addresses to capital letters). After this operation I'm click to Save and then apply changes. Then I'm redirect to apply.asp point. Page was white and device totally not respond. I must unplugged device from power line to restart it. SSH and any other ideas won't working too. Other problem - I can't change any configuration in: Setup -> Switch config. After I'm make changes and I try to save that. Router back to default configuration for this module and anything wasn't changes. This problem is for a long time.

Client Mode (WPA2 - Enterprise Peap Mode) does not work this broadcom firmware. The Marvell MVEBU based Hardware did not have this issues. I also tried the old method or new method with client mode connection. Both of them not working.

Status: bricked
I was made nvram erase before flash on 42287, flashed 42335 successful, booted, then made nvram erase again, after that R7000 goes to boot loop.
Please, provide me a quick link to debrick. Thanks.
