[WARNING]: This thread is only for feedback on this beta release for developers and the community's benefit.
DO NOT flash this beta release unless you understand the risks involved and specific device recovery methods.
Avoid discussions! Create threads for questions, general problems or use search; this thread is not for support.
Please list router model & revision, operating & wireless mode(s) and exact filename/firmware image flashed.

Downloads: (DD-WRT website) HTTPS & FTP (try another if a link doesn't work)

CLI Flash: 'cd /tmp' then 'wget {file URL}' (or 'curl -k {file URL} -o {file}') with http (not https) or ftp. Then 'write {file} linux'.

Repository: Trac SVN changelog since last build r43397 (GitHub mirror)

Notes:
• r41664 or later for SFE NAT (k3.2+), KRACK (k24+), PBR+SFE, CAKE & FQ_CODEL_FAST (reset!), GTK Rekey timer fixes.
• Reset button was broken at 40571, then fixed in build r40750.
• Experimental build option for Broadcom 8MB+ K2.x devices (limited currently): broadcom_K3X_mipsel32r1
• CVE-2019-14899 VPN fix (applicability depends on VPN setup) and GUI toggle. 6920, 6928, 6931, 6932 (WIP 7040)
• In-kernel Samba has been implemented this year and default min/max versions have changed 6954, 6957, with WSD support.
• Broadcom MIPS devices are now on kernel 4.4. N66U/AC66U half memory is fully resolved.
• Local DNS option removed from Services->DNSMasq in changesets 43080 and 43081; ref: #7092
• DHCP and DNS help (English) updated in 43083; ref: #7091
• WAN lease time approaching zero bug on WRT54* devices fixed in 43191; ref: #6456
• Images for WNR3500Lv2 (BRCM NAND flash crash bug) fixed in 43219 (43217); ref: #7098
• WireGuard: Policy Based Routing, Kill Switch, Inbound Firewall, Naming of Peers, Status, Key, Guides. Thanks egc!

Issues, observations, and/or workarounds reported:
• DNScrypt 1.95 can still be used in the GUI but v2 (not compatible) requires Golang and thus Entware. 6246
• WDS does not work on Broadcom ARM devices (only MIPS<->MIPS) and 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.
• 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, search).
• If start-up scripts do not work from USB add a delay (e.g. wait script or 'sleep 25').

Important:
• If reporting issues provide applicable info: 'dmesg', 'cat /tmp/var/log/messages', syslog/serial output, strace etc.
• For firewall issues provide 'iptables -L', 'iptables -t nat -L' and the /tmp/.ipt file.
• Search existing SVN tickets before opening a new one. Before reporting, reset and manually setup (no nvram backup).
• Be sure to include operating and wireless modes (Gateway, AP, CB, etc.) along with relevant configuration information.

Just flashed R7000 this morning, nothing to report other than the same issues of the 0 count for wifi and funny characters for JFFS2 info, however neither seem to affect performance. Will update if anything else shows up.

[kernel-panic69]

I would venture to say that the page allocation issue in your logs is related to using a Chromium-based browser or some add-on/extension to the browser OR not. I have not noticed this log entry on my E4200, but will keep an eye out. I will forward this log as well to see what BrainSlayer says.
