Notes:
• Experimental for 8MB+ K2.x devices: broadcom_K3X_mipsel32r1. • MIPS @ kernel 4.4. • TP-Link Archer C8 v2, v3 support.
• Privoxy, iperf3, CAKE, Asterisk, SmartDNS, curl, ProFTPD, BusyBox, OpenSSL, mac80211, FreeRADIUS, dnsmasq, Unbound, zfs, SoftEther, Squid, zstd, Tor
• In-kernel Samba (ksmbd 3.4.4): guest behavior is now selectable. • WSD update • ANTFS/NTFS3 kernel mode driver++++
• CVE-2020-26147, CVE-2020-24586, CVE-2020-24587 & CVE-2020-24588 fragattack fixed. • Broadcom swconfig supported.
• 'Assign WAN port to Switch' gone, set Connection Type Disabled. • WebUI MAC Filtering (47184-47205). • Sputnik removed.
• 'Ignore WAN DNS' also ignores WAN domain. • Milkfish removed. ◦
• New DD-WRT inspired themes conversion by the-joker & BrainSlayer, micro builds excluded, see UI theme test info thread.
• 401 bad request: Ethernet WebUI -> Wireless -> Basic Settings -> Advanced Settings -> Wireless GUI Access Enable, Save
• Add static or delete DHCP lease from clients table in Status -> LAN. Upgrades to forwarding delete, NAT / QoS tabs & more.
• Recent features, enhancements, fixes: Dynamic WDS, Stations, Site Survey, Radioname, Switch Config, Tagging and DTAG.

Issues, observations, and/or workarounds reported:
• WebUI: Clear history or use a portable. Temporary cache bypass: Ctrl+F5, Cmd+Shift+R or new private window/incognito.
• DNScrypt 1.95 can still be used in WebUI but v2 (not compatible) requires Golang and thus Entware. See Trac ticket #6246.
• WDS does not work on Broadcom ARM devices (only MIPS<->MIPS) & bridge modes on k4.4 devices may sometimes work
in some configurations for certain builds but are not supported by the bcmdhd driver. Try client or repeater modes, but YMMV.
• VAPs not working at boot are fixed, both unbridged (r40634) and bridged (r47822). Please test, remove startup commands.
• If startup scripts do not work from USB add delay (wait script), sleep 25 or try Administration -> Commands -> Save USB.
• Broadcom ARM devices if 5 GHz channels are missing via Telnet/SSH: 'nvram set brcm_unlock=1' 'nvram commit' 'reboot'.
• Please report findings with steps needed to reproduce, configuration, clients, output, logs and important information below!

Important:
• Detail issues & relevant configs. Logs: 'dmesg' 'cat /tmp/var/log/messages' syslog klog, serial, strace, tcpdump, wireshark.
• Any firewall NAT or WAN issues, show output: 'iptables -vnL' 'iptables -t nat -vnL' 'iptables -t mangle -vnL' and /tmp/.ipt file.
• Gremlins: reset & configure manually, not restore a backup. Reboot. Search Trac & discuss in forum before opening tickets.
• Include operating & wireless modes (e.g. Gateway, Router, AP, CB, WDS, Mesh) and applicable configurations to reproduce.

Issues/Errors:
Installed 48218 (experimental) with no errors. However, there was no WiFi transmission (2.4 GHz or 5 GHz) even though the status page showed radios working normally (but no connections, of course) and Syslog showed no errors. Did standard reboot with no change. Reverted back to r48141 and all working well.
