The first parameter will be the WAN unit (0 for first WAN, 1 for secondary). The second parameter will be a string describing the type of event (init, connected, etc...). A wan-event of type "connected" will be identical to when the original wan-start script was being run (wan-start should be considered deprecated and will be removed in a future release) - NEW: Implemented an official API for addon developers to better integrate with the router. This includes up to ten different pages that can be added anywhere within the webui, and a dedicated storage repository for your settings, which can be interacted with through your custom web page or through a shell script. See the Wiki for more information: https://github.com/RMerl/asuswrt-merlin/wiki/Addons-API - NEW: amtm (Asuswrt-Merlin Terminal Menu) by thelonelycoder has been added to the firmware. Running "amtm" over SSH will give you a menu allowing you to select and install various addons, such as Diversion (ad blocker) or SKynet (an advanced firewall extension). The plugins for amtm are still maintained by its original author (thelonelycoder). https://github.com/RMerl/asuswrt-merlin/wiki/AMTM - UPDATED: Backported some fixes from 384_81981, mostly related to WAN, port bonding and mdns. - UPDATED: Merged GPL 384_7756 for RT-AX88U, which adds OFDMA and WPA3 support to that model. - UPDATED: Merged with GPL 385_10002 for other models (from RT-AC68U) - UPDATED: odhcp6c to 1.1-97-ge199804 (themiron) - UPDATED: curl to 7.67.0. - UPDATED: openssl-1.0 to 1.0.2u - UPDATED: dnsmasq to 2.80-114-ge40d8be (themiron) - CHANGED: Replaced entware-setup.sh script with link to amtm, as using the amtm Entware installer is now the supported method. - CHANGED: Improved connection handling in httpd (themiron) - FIXED: Some of the newest DNSFilter servers weren't properly set up with IPv6 (dave14305) 384.13_4 (8-Feb-2020) This release is only available for the RT-AC87U and RT-AC3200. - NEW: wan-event script.

If you were affected and you had flashed a customized bootloader, then please reflash your original bootloader, as your modded bootloader is invalid, and other potential issues may appear over time. - FIXED: Random traffic spikes logged in Traffic Monitor (regression from 384_81351) 384.14 (14-Dec-2019) - NEW: Implement option to prevent Firefox's automatic usage of DoH. By default, this will only apply if you have DNSPrivacy enabled, or if you have DNSFilter enabled with a global filter, to ensure that Firefox will not bypass either of these. You can also have this override applied all the time, or completely disable it. - NEW: Added "split" busybox applet. - NEW: Added IPv6 support to Network Analysis webui - NOTE: You might need to reconfigure your device hostname on the LAN -> LAN IP page due to a GPL-level change (exclusing the RT-AX88U) - UPDATED: RT-AX88U to GPL 384_6436 (with Let's Encrypt fixes backported from 384_81351) - UPDATED: RT-AC68U, RT-AC86U to GPL 384_81351 - UPDATED: RT-AC88U, RT-AC3100 to GPL 384_81351 and binary blobs from 384_81116 - UPDATED: RT-AC5300 to GPL 384_81351 and binary blobs from 384_81219. - UPDATED: miniupnpd 20190824 - UPDATED: dnsmasq 2.80-95-g1aef66b (themiron) - UPDATED: OpenSSL 1.0.2 to 1.0.2t (themiron) - UPDATED: OpenSSL 1.1.1 to 1.1.1d (themiron) - UPDATED: Curl 7.66.0 - UPDATED: nano 4.4 - UPDATED: OpenVPN 2.4.8 - UPDATED: OUI database to 2018-08-17 version - UPDATED: CA root certificates to October 9th 2019 - CHANGED: Made webui SSL certificate generation compliant with IOS 13 and MacOS 10.15 new requirements. - CHANGED: Rewrote the faketc script used to inject Codel into Adaptive QoS as a C program for improved performance. - CHANGED: Moved /usr/bin/ip to /usr/sbin/ip on the RT-AC86U and RT-AX88U to match other models. - CHANGED: IPv6 firewall now accepts empty values for local IP (which means any local IP). - FIXED: Webui wouldn't notify when running dangerously low on free nvram (feature was lost at some point in the past) - FIXED: Non-working link to YandexDNS on the webui for Russian models. - FIXED: Backported various httpd fixes to RT-AX88 from other models. - FIXED: Custom clientlist would be wiped if stopping an OpenVPN server instance. - FIXED: Incorrect detection of EUI64 addresses on the IPv6 firewall (would prevent using ::/0 for instance). - FIXED: EUI64 support missing while in Load Balancing or using Multicast IPTV. - FIXED: Asus DDNS failing to update due to an invalid certificate on Asus's server. - FIXED: Let's Encrypt support would sometime fail when using Asus DDNS (fixed DNS publishing of validation record) (in addition to general failure fixed by GPL 81351) - FIXED: IPv6 neighbour solicitation drop toggle not working for some models - FIXED: openvpn-event scripts would be executed even if custom scripts were globally disabled 384.13_2 (14-Dec-2019) This release is only available for the RT-AC87U and RT-AC3200. - NEW: Added "split" busybox applet. - UPDATED: OpenSSL 1.0.2 to 1.0.2t (themiron) - UPDATED: OpenSSL 1.1.1 to 1.1.1d (themiron) - UPDATED: CA root certificates to October 9th 2019 - CHANGED: Rewrote the faketc script used to inject Codel into Adaptive QoS as a C program for improved performance. - CHANGED: Made webui SSL certificate generation compliant with IOS 13 and MacOS 10.15 new requirements. - CHANGED: IPv6 firewall now accepts empty values for local IP (which means any local IP). - FIXED: Non-working link to YandexDNS on the webui for Russian models. - FIXED: Webui wouldn't notify when running dangerously low on free nvram (feature was lost at some point in the past) - FIXED: Custom clientlist would be wiped if stopping an OpenVPN server instance. - FIXED: Incorrect detection of EUI64 addresses on the IPv6 firewall (would prevent using ::/0 for instance). - FIXED: EUI64 support missing while in Load Balancing or using Multicast IPTV. - FIXED: Asus DDNS failing to update due to an invalid certificate on Asus's server. - FIXED: Let's Encrypt no longer working due to deprecated ACMEv1 protocol usage (backport from GPL 81351) - FIXED: Let's Encrypt support would sometime fail when using Asus DDNS (fixed DNS publishing of validation record) - FIXED: IPv6 neighbour solicitation drop toggle not working for some models 384.13_1 (12-Aug-2019) - FIXED: RT-AC87U failing to boot when configuring in AP mode. 384.13 (31-July-2019) - NEW: AiMesh Router and node support. Note that automatic live update of Merlin-based nodes is not supported, you will have to manually update any Merlin-based nodes when a new firmware is available. Asus-based nodes (which is recommended) will be able to make use of the automatic live update. - NEW: ChaCha20-Poly1305 support in Strongswan (themiron) - UPDATED: RT-AX88U to GPL 384_6210. - UPDATED: Curl 7.65.3. - CHANGED: dhcp_staticlist no longer contains hostnames, these have been moved to dhcp_hostnames for better compatibility with upstream and closed source components, also allows more static leases to be defined before reaching the size limit. - CHANGED: Replace Nettle with OpenSSL for dnsmasq's DNSSEC validation, which opens the door to supporting more ciphers. (themiron) - FIXED: Firmware Update check button would redirect to Asus support site if scheduled checks are disabled. - FIXED: Firefox was showing a no-op Uninstall button on the AiCloud page - FIXED: 5 GHz radio showing as disabled on the Sysinfo page for the RT-AC87U - FIXED: FTP would be accessible from the WAN even while disabled if you had DualWAN load balancing enabled, or IPTV configured. - FIXED: IGMP Snooper daemon crashing when more than 32 hosts are present (themiron) - FIXED: External DDNS IP checker would fail for Chinese users, as checkip.dyndns.org is blocked - switched to .com TLD. - FIXED: Devices without a networkmap-defined alias wouldn't fallback to their hostname on some webui pages like the IPTraffic and QoS Classification pages. - FIXED: Remote IP field filtering on Classification page wasn't working. - FIXED: Incorrect user permissions displayed on the FTP page. - FIXED: Performance issues for some users, following the kernel security fixes in 384.12.

Official website is now https://www.asuswrt-merlin.net/ and my email address for anything related to the project is now [email protected] - NEW: Added WS-Discovery support. This allows Windows clients to detect the router's shared USB drives even if SMBv1 support is disabled. - NEW: Re-added option to extend the WAN's TTL (from stock firmware, was previously disabled as it used to be broken) - UPDATED: RT-AC3200 and RT-AC87U to 382_51640/51634 binary blobs (with a few exceptions for 384_xxxx compatibility) - UPDATED: Merged GPL 384_45717 (except for RT-AX88U) - UPDATED: Nano 4.2. - UPDATED: OpenSSL-11 to 1.1.1c. - UPDATED: OpenSSL-10 to 1.0.2s. - UPDATED: curl 7.65.1. - UPDATED: miniupnpd 20190604. - CHANGED: Local clients will be shown by their hostname on the Classification page. - CHANGED: Reworked handling of up/down events in OpenVPN. Server instance will now also use its own updown script, which will handle firing up openvpn-event (if present). - CHANGED: Inbound traffic sent to you through an OpenVPN client will now be dropped by default. This can be changed through the new "Inbound Firewall" parameter found on the OpenVPN client page. You should only change this to "Allow" if running a site2site tunnel with a trusted remote server, or if you do expect traffic to be forwarded to you through the tunnel. - CHANGED: The router will now use ISP-provided resolvers instead of local dnsmasq when attempting to resolve addresses, for improved reliability. This reproduces how stock firmware behaves. This only affects name resolution done by the router itself, not by the LAN clients. The behaviour can still be changed on the Tools -> Other Settings page. - CHANGED: Randomize the serial number of certificates generated by the router for its httpd. If using a router-generated certificate, then it's recommended to generate a new one. - CHANGED: Allow USB idle values up to 9999. - CHANGED: Replaced Network Analysis and Netstat pages (under Network Tools) with new versions based on Asus's Netool daemon for non-HND models, but based around the more limited traceroute busybox applet. RT-AC86U and RT-AX88U still use the newer traceroute executable. - CHANGED: Reworked how some services are started when the WAN interface comes up to prevent deadlocks between the WAN completing its initialisation, and the clock getting set. These could result is fairly long boot time for some ISPs. - FIXED: openvpn-event script not launching if the client was configured in Secret Key auth mode. - FIXED: IPv6 issues on RT-AX88U - backported accept_ra fix from 45717 (themiron) - FIXED: Memory leak in erp_monitor process. - FIXED: Page redirection failing to apply at boot time if WAN was down. - FIXED: CVE-2019-11477, CVE-2019-11478 and CVE-2019-11479 (themiron) 384.11_2 (18-May-2019) - NEW: Implemented source/destination IP filtering for the Netool version of Netstat web page. - CHANGED: Backported multiple fixes and improvements for ntpd from upstream, improving handling of failed server hostname resolution, and better clock sync discipline. - FIXED: RT-AC88U/3100/5300 were accidentally compiled with Netool enabled, which isn't compatible with these model's kernel. - FIXED: Movistar stopped working for some users. Re-disabled udpxy on Movistar profile for now. A more complete fix will have to come from Asus. - FIXED: Re-disabled memaccess debugging tool, as it creates a symlink called "sh" which is a pretty bad idea from Broadcom. (RT-AC86U, RT-AX88U) 384.11 (8-May-2019) - NEW: Added DNS Privacy feature, with support for DNS-over-TLS (also known as DoT). You can configure it on the WAN -> Internet Connection page. You can manually add your own servers, or chose one (or a few) from the preset list. (themiron) - NEW: NTP daemon on the router, to allow your LAN clients to synchronize their clocks with it. - NEW: Option to intercept NTP requests from clients, and redirect them to the router's own NTP daemon. - NEW: Added service-event-end custom script, executed at the end of an rc service call. Receives the same arguments as service-event, but is a non-blocking script. - NEW: Added sqlite3 CLI command, to allow script authors to create/manage their own sqlite3 database - UPDATED: RT-AX88U to 384_5951 GPL. - UPDATED: Other models to 384_45713 GPL (RT-AC87U, RT-AC3200 and RT-AC5300 still using 384_45149 binary blobs) - UPDATED: Nano 4.0. - UPDATED: Curl 7.64.1. - UPDATED: Dropbear 2019.78. - CHANGED: Replaced the custom ntpclient with a proper ntpd implementation, for reduced memory usage and increased accuracy. - CHANGED: Made the secondary NTP server configurable through the webui. Note that ntpd will use both servers, so clear the second server if there is one and you don't want to use it. - CHANGED: Re-designed firmware upgrade page, moving the schedule option to that page, and removed support for the Beta channel. - CHANGED: Removed popup messages showing on the DDNS page when a service state change was detected. Report it within the page instead. - CHANGED: Report firmware version within the new firmware notification popup that appears at the top of the webui. - CHANGED: Moved LED control (formerly known as Stealth Mode) to the System page. - CHANGED: Do not restart whole network whenever changing an IP reservation on the Networkmap card. - CHANGED: Allow URLs up to 64 chars long on the URL filter. - CHANGED: pre-mount user script now receives the filesystem as second argument. - CHANGED: Moved various DNS-related settings from the DHCP page to a more appropriate location on the WAN page. - CHANGED: OpenSSL default dir moved to /etc/ssl/. Allows programs to automatically locate the CA bundle without requiring explicit configuration. - CHANGED: Optimized service restarts generated by the System page. - CHANGED: Replaced Network Analysis and Netstat pages (under Network Tools) with new versions based on Asus's Netool daemon (RT-AC86U, RT-AX88U) - FIXED: Reboot scheduler would sometime get stuck, or corrupt plugged USB drives. Now doing a more thorough shutdown of services, should hopefully make it more reliable. - FIXED: CVE-2019-1543 issue with Chacha20-poly1305 in OpenSSL 1.1 (themiron) - FIXED: Client count on the Sysinfo page was missing Guest clients - FIXED: Miniupnpd sometimes sending ssdp notifies to the wrong interface (themiron) - FIXED: udpxy not working when using the Movistar IPTV profile on RT-AC86U and RT-AX88U. 384.10_2 (3-Apr-2019) - CHANGED: Increased OpenVPN interface queue length from 100 to 1000 bytes, to reduce the amount of dropped packets if router can't keep up. - CHANGED: Updated CA bundle to January 23rd version - FIXED: Moviestar VLAN routes weren't properly configured (broken quagga configuration) - FIXED: Layout issues on the Wireless Log page for some models - FIXED: Missing tooltip content for the new local DNS resolution setting on the Tweak page - FIXED: FAQ URL on Bandwidth Monitor points to a non-existing page on Asus's servers (point to old page for now) - FIXED: OpenVPN CA would be overwritten if there was no server key or cert present - only generate them if all three are missing. - FIXED: Bandwidth Limiter not working properly in some cases, as it failed to disable hardware acceleration 384.10 (24-March-2019) - NEW: Added OpenSSL 1.1.1b in parallel to 1.0.2. Some services like AiCloud are still linked against 1.0.2 because they would require Asus to recompile them against 1.1.1. Main services that currently use OpenSSL 1.1.1: httpd (webui), OpenVPN, wget, net-snmp, Tor, Strongswan (IPSEC server), inadyn, vsftpd, avahi. Models that lack AES acceleration will prioritize the use of CHACHA20 over AES-256-GCM, for a small performance improvement (for instance with the webui). Note that OpenVPN 2.4.7's support is still limited. TLS 1.3 is supported, but CHACHA20 support is only expected with OpenVPN 2.5.0. The 1.0.2 userspace tool is still named "openssl", while the 1.1.x version is named "openssl11". - NEW: Updated RT-AX88U to GPL 384_5640. - NEW: Implemented lcp-ident option in PPP (required by some ISPs) (Themiron). - NEW: Added NFSv2 support to HND models. - NEW: You can now choose between having your router do internal DNS queries locally (through dnsmasq) or with your WAN configured DNS (like stock firmware). This does not affect DNS lookups from your clients, only those made by the router itself. The option is under Tools -> Other Settings. (Themiron) - CHANGED: Some firmware cleanups to regain flash space (for use with the parallel OpenSSL 1.1.x install) (RMerlin, Themiron) - CHANGED: Updated curl to 7.64.0. - CHANGED: Updated OpenVPN to 2.4.7. - CHANGED: Updated Tor to 0.3.5.8. - CHANGED: Updated strongswan to 5.7.2. - CHANGED: Updated OpenSSL 1.0.x to 1.0.2r. - CHANGED: Updated dnsmasq to 2.80-44-g608aa9f (Themiron) - CHANGED: Re-worked the Classification page. New design is much faster, allows filtering, and shows additional info when hovering on a field. Thanks to FreshJr for giving me the motivation to spend more time on it. - CHANGED: Strongswan is no longer compiled 64-bit on HND, allowing it to use a shared openssl library instead of a static one. This should significantly reduce the memory and flash usage of Strongswan. (Themiron) - CHANGED: Reworked DNS WAN probe implementation (Themiron) - FIXED: IPSEC log display wasn't properly formatted (showed entirely on a single line) - FIXED: Compatibility issues between recent Tuxera NTFS driver and Samba - FIXED: NFSv2 support - FIXED: PPP host-uniq support (Themiron) - FIXED: AiCloud not working on the RT-AX88U - FIXED: OpenVPN key/certs would sometime end up in nvram in addition to in /jffs - FIXED: Couldn't remove an existing OpenVPN key/cert by clearing the field on the webui - FIXED: Resetting OpenVPN client to Default values wasn't removing any existing Extra CA certificate - REMOVED: Beceem Wimax driver. This is deprecated, and was already removed from the HND models. This allows to reclaim close to 2 MB of flash space. - REMOVED: CFB and OFB ciphers from OpenVPN client 384.9 (2-Feb-2019) - NEW: Temporarily reorganized code in separate branches, to handle Asus's currently scattered firmware source code releases. The GPL situation for this release is as follow: o RT-AX88U: Merged GPL 384_5329 o Other models: Merged GPL 384_45149. o Special binary blobs provided by Asus for the RT-AC87U and RT-AC3200 (compatible with 384_45149). - NEW: Added NFS client support (V2 and V3) to the RT-AC86U and RT-AX88U (already present in older models) - NEW: Report the number of spatial streams and the PHY type used by wireless clients for models supporting it - NEW: Display tracked connections on the QoS Stats page (now relabeled "Classification"). Fields can be sorted by clicking on the column headers. Thanks to FreshJr for his help in deciphering the packet mark values. - NEW: Implemented ipsec.postconf and strongswan.postconf scripts. - KNOWN ISSUE: dcd process crashing on RT-AC86U (bug in Trend Micro's code, outside of my control). - KNOWN ISSUE: IPv6s on Tracked Connections have their last two bytes set to 00 (bug in Trend Micro's code truncating the last two bytes). - KNOWN ISSUE: No IPS events logged (bug in Asus's code, IPS should work, just fails to log hits) - KNOWN ISSUE: Networkmap listing may be unreliable. (Bug in Asus's code) - KNOWN ISSUE: Users failing to read changelogs will probably complain about the above issues. (Outside of my control). - CHANGED: Updated wget to 1.20. - CHANGED: Updated nano to 3.2. - CHANGED: Updated curl to 7.62.0. - CHANGED: Updated Chart.js to 2.7.3. - CHANGED: Updated dnsmasq to 2.80-32-g28cfe36 (themiron) - CHANGED: Optimized some JS files to reduce their size - CHANGED: OpenVPN clients can now accept CNs up to 255 chars when using it to validate the certificate. - CHANGED: No longer reset the OpenVPN client's description, policy mode and existing rules when uploading an .ovpn config file. - CHANGED: No longer accept any server-provided route when OpenVPN client set to Policy (Strict). - CHANGED: Clients bound to DNSFilter rules will no longer bypass it by using DoT. DNSFilter servers that support DoT (like Quad9) will only allow filtered clients to use that server - FIXED: Firmware update checks would not run at boot time on the RT-AX88U. - FIXED: Name resolution issues for /etc/hosts entries on HND models (themiron) - FIXED: Syslog not properly copied to JFFS on reboot (John Bacho) - FIXED: Volumes not properly unmounted on HND platform (John Bacho) - FIXED: Added missing TEE Netfilter target on the RT-AC86U - FIXED: SSH brute force protection didn't work in Dual WAN load balancing mode. - FIXED: httpd crashes on RT-AC86U (themiron) - FIXED: DNSFilter clients could use a different nameserver when using an IPv6 connection - FIXED: USB disk idle config changes not applying without a reboot. - FIXED: "Strict" DNS mode wasn't working properly with OpenVPN clients - FIXED: Cannot upload JFFS backup on HND models 384.8_2 (8-Dec-2018) - CHANGED: Updated miniupnpd to 20181205. - CHANGED: Push LAN domain to OpenVPN clients as DNS suffix for the connection. - FIXED: Cannot save custom settings on OpenVPN server page on non-HND models. - FIXED: Some webui pages fail to load properly in French - FIXED: dnsmasq fails to start when certain options are configured (themiron) - FIXED: Non-functionnal Show Password option on OpenVPN/PPTP server page for RT-AX88U (removed) - FIXED: Persistent SSL cert was wiped at boot time in some specific scenarios. 384.8 (2-Dec-2018) - NOTE: Asus has put the RT-AC56U on their End of Life list, meaning no further firmware releases from them. Since it's impossible for me to support models without matching GPL releases from Asus, I also have to retire the RT-AC56U. 384.6 is the final release for that model. - NOTE: The RT-AC3200 and RT-AC87U are not supported by this release, Asus hasn't released any updated code yet for these models. - NEW: Added RT-AX88U support (based on GPL 384_4736). - NEW: Merged with GPL + binary blobs from 384_32799 (all supported models except RT-AX88U) - NEW: Add LZ4 V2 option to OpenVPN compression (more effective at handling already compressed data) - NEW: Added "extend" support to SNMP. - NEW: Added CleanBrowsing to DNSFilter supported services. - NEW: Webui HTTP LAN port can now be changed from the default 80. - NEW: Added support for the Netfilter TEE target. - CHANGED: Removed watchdog from OpenVPN clients, to avoid conflicting with more advanced configurations. - CHANGED: Vsftpd TLS mode will now reuse the web server certificate (including any Let's Encrypt generated one). - CHANGED: SSL crypto/cipher hardening for httpd (themiron) - CHANGED: Syslog will now ignore bwdpi debug output (themiron) - CHANGED: Reworked Wireless Log page, adding a new button to view low-level details (what stock firmware shows on its Wireless Log page), and removed redundant option to display DFS channel details. - CHANGED: Update dnsmasq to 2.80-11-g59e4703 (themiron) - CHANGED: Updated nettle to 3.4 - CHANGED: Updated net-snmp to 5.8 - CHANGED: Updated openssl to 1.0.2q - CHANGED: Migrated /jffs/ssl/* content to /jffs/.cert (to share the same folder used by Asus stock) - CHANGED: Re-enabled WTFast on non-HND models (curl-related crash has been fixed). This is still untested. - CHANGED: Updated CA bundle to October 17th 2018 version. - CHANGED: Support search domains pushed by a remote OpenVPN server - FIXED: UOPNP port forwarding not working in CGNAT/double NAT scenario even if proper ports were forwarded upstream. - FIXED: Pages based on table.js (like the port trigger one) would fail to work properly under Firefox (Michael Ziminsky) - FIXED: Dnsmasq issues when running in non-router mode (John Bacho) - FIXED: Routing issues when in non-router mode (John Bacho) - FIXED: Bug in curl that could cause some applications to crash on non-HND models - FIXED: IFTTT failing to start on non-HND models (caused by curl issue). - FIXED: Webui could complain about port 8080 being reserved for http WAN port (which is no longer supported) - FIXED: Cannot change image for device with a vendor name containing an apostrophe (like Micro-Star int'l) (Asus bug) - FIXED: OpenVPN client download was capped by Adaptive QOS upload limit (fix devised by FreshJR) - FIXED: OpenVPN custom config might be lost after a reboot on the RT-AC86U. 384.7_2 (21-Oct-2018) - FIXED: Namecheap DDNS service not working - FIXED: CVE-2018-15599 security issue in Dropbear - FIXED: Potential buffer overrun in httpd 384.7 (7-Oct-2018) - NOTE: The RT-AC3200 and RT-AC56U are not supported by this release, Asus hasn't released any updated code yet for these models. - NOTE: Important changes to DDNS, please read below. - NOTE: Important changes to DNSFilter, please read below. - NEW: Merged with GPL 384_21152. - NEW: Merged RT-AC87U binary blobs + SDK from 382_50702. - NEW: Replaced old ez-ipupdate DDNS client with In-a-Dyn. A plugin was developed to fully support Asus's DDNS service. Custom services can now be configured through ddns-start, inadyn.conf, inadyn.conf.add or inadyn.postconf. See the In-a-Dyn documentation as many custom services can be defined for it. - NEW: Added support for freedns.afraid.org DDNS service to webui. - NEW: Added option to retrieve WAN IP from either the local interface (like before) or through a remote server (which works through double NAT) for DDNS. - NEW: Display DFS channel info on Wireless Log page. - NEW: Added option to disable checks on unsigned DNSSEC replies. Disabling these will speed up lookups, but it will also remove part of the security benefits of DNSSEC, so it should not be used unless you have a very specific reason to do so. - NEW: Added Quad9 to DNSFilter supported services. - CHANGED: Updated curl to 7.61.1. - CHANGED: Updated wget to 1.19.5. - CHANGED: Updated openssl to 1.0.2p. - CHANGED: Updated dnsmasq to v2.80test8 (themiron). - CHANGED: Updated nano to 3.1. - CHANGED: All DDNS services now use HTTPS. - CHANGED: Replaced Google Domains DDNS script with In-a-Dyn's own plugin. - CHANGED: Moved DNSFilter to the LAN section, to make it clear that it's unrelated to Trend Micro's engine. - CHANGED: Report hostname and IP on Wireless Log page if the info is missing from dnsmasq but available from networkmap. - FIXED: Invalid dnsmasq config when setting DNSFilter to Router mode and having IPv6 enabled (themiron). - FIXED: dnsmasq crashing on RT-AC86U with IPv6 Stateful mode (themiron). - FIXED: client table would be shown twice on the VPN Status page if the only connections to an OVPN server were invalid clients (like a port scanner) - FIXED: DDNS forced updates after "x" days wouldn't be initiated. - FIXED: CERT VU#598349 vulnerability (DHCP client could claim the special "wpad" hostname) - REMOVED: Ez-ipupdate DDNS client (replaced with In-a-Dyn). Update your scripts if you were relying on it. - REMOVED: Norton Safe DNSFilter services (being discontinued by Symantec in November). Configured clients will be automatically migrated to OpenDNS Family - make sure to edit your DNSFIlter settings if you desire to use a different service. 384.6 (25-July-2018) - NOTE: The RT-AC87U is not supported in this release, as Asus hasn't released any updated code for that model. - NEW: Merged with GPL 384_21045/382_50624. - NEW: Added support for the "-p" option to netstat. - NEW: Added setting to enable DNS rebind protection, on the DHCP page. This works by rejecting upstream server responses that would point at a private IP. - CHANGED: Updated nano to 2.9.8 - CHANGED: Updated curl to 7.60.0 (contains security fixes) - CHANGED: Allow selecting text (for copy/paste operations) on AiProtection pages. - CHANGED: Added AES-*-GCM ciphers to the OpenVPN legacy ciphers (so they can be explicitely used without using NCP). - CHANGED: Updated dnsmasq to 2.80test2-17-g51e4eee (themiron) - CHANGED: Since dnsmasq 2.80, dnsmasq now ensures that unsigned DNS replies received with DNSSEC enabled are legitimate. If your upstream DNS doesn't support DNSSEC, this means all replies from signed zones will be considered invalid. Make sure you only enable DNSSEC if your upstream DNS servers do support it. This behaviour is a bit slower, but far more secure than the old default. - CHANGED: Network Tools -> Netstat output also report program/PID - CHANGED: Updated CA bundle to June 20th version. - FIXED: IPv6-related issues on non-HND platform (themiron) - FIXED: Couldn't log on WTFast if accessing the router webui over https. - FIXED: USB modem support code failing to properly pass parameters to the kernel module (themiron) - REMOVED: WTFast support for RT-AC88U/RT-AC3100/RT-AC5300, as it's incompatible with recent versions of curl (and has been broken for quite some time). Not gonna revert back to a 7 years old curl version just for wtfast. 384.5 (13-May-2018) - NEW: Merged withh GPL 384_20648 - NEW: Merged RT-AC68U, RT-AC5300 binary blobs from 384_20648 - NEW: Merged RT-AC86U SDK and binary blobs from 384_20648 - NEW: service-event script, executed before any service call is made. First argument is the event (typically stop, start or restart), second argument is the target (wireless, httpd, etc...). Note that this script will block the execution of the event until it returns. - NEW: Added USB HID modules (for use with devices such as UPS) - NEW: Added ip6tables-save command. - CHANGED: Updated OpenVPN to 2.4.6. - CHANGED: Updated Dropbear to 2018.76. - CHANGED: Updated Openssl to 1.0.2o. - CHANGED: Updated miniupnpd to version 2.1 (20180508). - CHANGED: Updated nano to 2.9.5. - CHANGED: Moved RT-AC86U to the same Busybox version (1.25.1) as other models. - CHANGED: Revised OpenVPN server options: o Removed "TLS Reneg time" (rarely used, can manually be set as a custom option) o Removed "Server Poll" (which didn't work properly), and reimplemented watchdog service, hardcoded to 2 mins frequency. o Removed "Push LAN" and "Redirect Gateway", replaced with new Client Access setting o Removed Firewall setting (firewall rules are now always created, and the broken External mode was fixed and integrated into the new Client Access setting). You can now use the postconf script to override it. o Removed option to respond to DNS queries - enabling the option to Push DNS will also handle it o Added new Client Access setting to select between three types of access: LAN only, WAN only (will block access to the LAN, including the router itself) and LAN + WAN. o Keys and certificates can now be up to 7999 characters long. - CHANGED: Revised OpenVPN client options: o Reorganized settings into groups o Removed "Poll Interval" (which didn't work properly), and reimplemented watchdog service, with a hardcoded frequency of 2 mins. o Removed Firewall setting (firewall rules are now always created). You can now use the postconf script to override it. o Modified behaviour of Connection Retry. Instead of taking a value in seconds that only affected resolution failure, it now takes a number of attempts, and affects connection failures. Resolution failures will now retry for an infinite period of time (the default OpenVPN value). o Added "refresh" link which can be clicked to re-query the public IP endpoint of the tunnel o Keys and certificates can now be up to 7999 characters long. - CHANGED: Removed option to resolve names on the Log -> Connections page. That functionality was added to the Network Tools -> Netstat page instead. - CHANGED: Re-designed Log -> Connections page into a table with sortable fields - click on a column header to sort on that field. - CHANGED: From now on, setting the router to act as a master browser or a WINS server will also require you to enable sharing. This will ensure that users understand that enabling either of these settings requires disk sharing to also be enabled (which it was already silently doing before). - CHANGED: Moved "Beta firmware" option to the Tools -> Other Settings page - CHANGED: Improved layout of the Firmware Update page - CHANGED: WPAD behaviour (sending a carriage return on DHCP option 252) can now be controlled in the Tweaks section. - CHANGED: Blocking custom scripts such as service-event and pre-mount will now wait a maximum of 120 seconds before resuming normal operations, to prevent accidental lockouts. - CHANGED: Autofill start/end time for DST when selecting a timezone (LostFreq) - FIXED: Some dnsmasq issues related to DNSSEC were fixed, including CVE-2017-15107. (backported from dnsmasq 2.79 by John Bacho) - FIXED: Restoring an OpenVPN instance to default values would fail to disable its Start with WAN setting. - FIXED: Hardware authentication failure for the RT-AC3100 and RT-AC5300. - FIXED: Minidlna web status page could no longer be enabled. - FIXED: CVE-2017-9022, CVE-2017-9023 and CVE-2017-11185 in Strongswan (odkrys) - FIXED: Various issues with download traffic in Traditional QoS (Cédric Dufour) - FIXED: TCP timeout values couldn't be changed on the Tools -> Other Settings page. - FIXED: Security issue related to webui logging in (Asus bug) 384.4_2 (24-Mar-2018) - CHANGED: Added visual warning when manually enabling webui access on WAN. Doing so carries serious potential security risks, as Asuswrt's web server code should not be considered hardened enough for this. - FIXED: Security issue in httpd (CVE-2018-8879). - FIXED: Potential security issue in httpd related to QiS. - FIXED: Minor webui issue in the QoS overhead menu. 384.4 (16-Mar-2018) - NEW: Merged with GPL 384_20379 (with some binary components from 382_50010 and 384_20308 depending on models) - NEW: Added support for the RT-AC5300. - NEW: Added support for the RT-AC87U. - NEW: Added IPSEC support to the RT-AC86U. - NEW: Support the new Entware 64-bit repo on the RT-AC86U. To switch to the new repository, re-run the entware-setup.sh script. You will need to reinstall your apps (your old config files are backed up on your USB disk). - CHANGED: Tightened security around some config files. - CHANGED: Allow guest networks settings for AP isolation and SSID broadcast to be set separately from their parent interface (John Bacho) - CHANGED: Samba protocol support can now be set to SMBv1, SMBv2, or SMBv1 + SMBv2 (the new default). This will result in a performance drop on all models but the RT-AC86U, but will be more secure. Ideally, people should change it to SMBv2 only, and then reboot all their client devices to start using only the new protocol. - CHANGED: Re-added some of the logging sd-idle used to do in 380.xx. - CHANGED: Switched to the new Entware repo for armv7 models. To upgrade, run the following commands TWICE: opkg update; opkg upgrade - FIXED: Resetting an OpenVPN client to default settings might revert back after a reboot. - FIXED: log flood from lldpd about "unable to send packet on real device" (moved to debug level) - FIXED: Potential racing condition that could lead to two instances of miniupnpd running at boot time. - FIXED: Single-char hostnames were rejected by DHCP static leasees page. (theMIROn) - FIXED: AiCloud could sometime generate a new SSL certificate that would overwrite the one stored in jffs. Now, AiCloud can also use the same one uploaded by the user for the main webui, or the Let's Encrypt one. - REMOVED: Telnet server. Please use SSH for console-based management. - REMOVED: SNMP support on the RT-AC86U (incompatible) - REMOVED: Merlin NAT loopback mode (was increasingly problematic as the firmware firewall handling became more complex) 384.3 (14-Feb-2018) - NOTE: To reduce confusion following the version bump to 384, the current Github repository was renamed from asuswrt-merlin.382 to asuswrt-merlin.ng (for New Generation). It's recommended that you update your local repository if you're a developer, for example by running: git remote set-url origin \ [email protected]:RMerl/asuswrt-merlin.ng.git - NOTE: AiMesh is currently not supported. Feasability of supporting it is still under evaluation. - NEW: Merged with GPL 384_10007 - NEW: Added support for RT-AC3200 (merged SDK 7.x-main + binary blobs from 382_19466). - NEW: nano can now be configured through /jffs/configs/nanorc - CHANGED: Allow up to 5 OpenVPN clients on RT-AC3200. - CHANGED: Updated nano to 2.9.3. - FIXED: Some routers coming from 380.xx would incorrectly report a new firmware available at boot time. - FIXED: Some broken clients (like Samsung TVs) try to use reserved hostnames - ignore these. (theMIRon) - FIXED: Added missing IPv6 local hostnames (theMIRon) - FIXED: Issues withh DNS & broadcast relay for pptp clients (theMIRon) - FIXED: Fixed CVE-2018-5721 in httpd (Merlin & theMIROn) - FIXED: helper.js wasn't properly handling parentheses (John9527) - FIXED: NAT acceleration of PPPoE for some models (fix backported from 382_50010) - FIXED: Networkmap-related issues on some models (missing tx/rx rate and such). - FIXED: ipset could cause the router to crash on the HND platform (john9527) - FIXED: Network Service Filter wasn't working when in Blacklist mode. - FIXED: Repeater mode (backport from 384_20287) 382.2 Beta (17-Jan-2018) - NOTE: Due to various issues with GPL 382_18991, the 382.2 release is being dropped, and work is moving on to the next version. 382.2 beta releases remain available for those who still wish to use it (especially RT-AC56U users for whom there is no ETA as to when Asus will release the next GPL for that particular model.) Known issues include lack of PPPoE HW acceleration and Adaptive QoS sometimes failing to start at boot among others. - NOTE: The official IRC channel has moved to Freenode (#asuswrt). - NEW: Merged with GPL 382_18991. Most notable changes (will vary between models): - Added IPSec VPN server - Added IFTTT and Alexa support - Let's Encrypt support (DDNS page) - Better support for some longer settings (RT-AC86U) - NEW: Merged HND SDK + binary components from 382_18848 (RT-AC86U) - NEW: Added IPSec VPN status on the VPNStatus page. - NEW: Added support for RT-AC56U and RT-AC68U (and all of its variants) - NEW: Enabled support for Let's Encrypt on RT-AC56U and RT-AC68U (in addition to RT-AC88U/3100) - CHANGED: Moved HTTPS cert management to the DDNS page (where Asus has put theirs, as Let's Encrypt is tied to the DDNS configuration) - CHANGED: Updated openssl to 1.0.2n. - CHANGED: Updated tor to 0.2.9.14. - CHANGED: Updated nano to 2.9.1. - CHANGED: Updated curl to 7.57.0. - CHANGED: Increased max length for OpenVPN custom settings from 170 to 510 characters on RT-AC86U. - CHANGED: Updated miniupnod to Github snapshot 20171212. - CHANGED: OpenVPN firewall rules are now processed after the various security chains (access restriction, network service firewall, etc...), ensuring OVPN traffic no longer bypasses them. - FIXED: httpd crash on certain web pages if there are no Ethernet clients connected - FIXED: DNSFILTER rules would have priority over OPENVPN Client rules (when client has DNS set to Exclusive mode). - FIXED: traffic routing from the router itself would fail when restarting the firewall while using an ovpn client with policy rules in effect. - FIXED: Dashes were rejected when used in an OpenVPN policy client description. - REMOVED: Removed option to select between active and passive scan mode for a site survey (that code is now closed source and therefore that option can no longer be implemented). 382.1_2 (2-Dec-2017) - NEW: Added custom/add/postconf support for mcpd.conf (RT-AC86U) - CHANGED: Updated odhcp6c to latest upstream version (patch by theMIRon) - CHANGED: cifs and xt_set kernel modules will get automatically loaded as needed. - CHANGED: Updated openssl to 1.0.2m. - CHANGED: Updated libogg to 1.3.3 and libvorbis to 1.3.5. - CHANGED: Merged wireless components from GPL 382_18991 for RT-AC88U and RT-AC3100 (should in theory fix KRACK issue on these two models) - FIXED: allow IA_NA mode downgrade with forced IA_PD (for ISPs with broken IPv6 support) (patch by theMIRon) - FIXED: SSH brute force protection would break WAN connectivity (RT-AC86U) - FIXED: Wrong Trend Micro signature updater was used when compiling with FW update checker enabled. - FIXED: QoS Upload chart missing on PPPoE connections with Adaptive QoS enabled. - FIXED: client and vendor id fields on WAN page would fail to accept new values longer than 32 characters. - FIXED: The Desc field in the OpenVPN policy section would reject ":" if field contained a MAC address. - FIXED: Security issues CVE-2017-15275, CVE-2017-12163 and CVE-2017-12150 (backported to Samba 3.6 and 3.5) - FIXED: DHCP static lease list would refuse any change if the list of leases+hostnames was longer than 1000 chars due to an HND platform limitation (RT-AC86U) 382.1 (12-Nov-2017) Asuswrt-Merlin 382 was rebuilt from a clean GPL codebase, as merging the new 382 GPL on top of the existing code proved too difficult. For simplicity, the following abbreviations are used below: AM380 = Asuswrt-Merlin 380.xxx AM382 = Asuswrt-Merlin 382.xxx Asus380 = Asus's 18.104.22.168.380_xxxx Asus382 = Asus's 22.214.171.124.382_xxxx AM382.1 is based on AM380.68_4 merged on top of a clean 126.96.36.199.382_15098 GPL. At this time, only the RT-AC86U, RT-AC88U and RT-AC3100 are supported by AM382. Other models will gradually be moved to AM382 as Asus upgrade them to the new 382 code base (and GPL code becomes available for them). This changelog will focus on changes that happened between AM380.68 and AM382.1, or between Asus382_16466 and AM382. Also note that the primary download site was changed to Sourceforge, due to numerous issues with Mediafire. Onedrive will be the official mirror to the SF.net download site. - NEW: Moved to Asus382 codebase. Some of the most important changes between Asus380 and Asus382: - New Trend Micro DPI engine, with two-way IPS - New networkmap service (now closed source) - New OpenVPN implementation (now closed source, not used by AM382) - Numerous security enhancements throughout the code - NEW: Merged with GPL 382_16466 (RT-AC86U). - NEW: Added support for the RT-AC86U and its Broadcom HND platform (HND SDK from GPL 382_18219). Note that IPTraffic is not supported by this model due to its newer Linux kernel. - NEW: Rewrote part of the OpenVPN implementation, as Asus's own is now closed source. Asuswrt-Merlin's OpenVPN code will now be independent of Asus's. - NEW: Added support for inline CRLs when importing an ovpn file - NEW: Added support for fullcone NAT (RT-AC86U) - NEW: Added WiFi Radar (Broadcom's Visualization app) in the Wireless section. You must enable data collection on its Configuration page for all charts to work properly. (RT-AC86U) - NEW: Added option to disable the Asus NAT tunnel service under Other Settings -> Tweak. Not quite sure what this partly closed source service is for, but it eats a fair amount of CPU and RAM. - NEW: Option on OpenVPN Server page to quickly choose between pushing LAN or LAN + Internet access (ported from Asus382) - NEW: Option to select the bitsize to use (1024 or 2048) when automatically generating the OpenVPN server key/certs (ported from Asus382) - CHANGED: Updated wget to 1.19.2 (fixing connectivity to some TLS 1.2 servers) - CHANGED: SSH host keys are now stored in /jffs/ssl/ rather than nvram. - CHANGED: SMB2 is enabled by default on RT-AC86U (no performance penalty on that platform) - CHANGED: Moved UPnP Secure Mode setting from the Tweaks section to the WAN page, next to other UPnP settings. - CHANGED: Moved "Modify key and certs" link to its own dedicated row and made it a button for improved visibility (OpenVPN client & server pages) - CHANGED: Updated OpenVPN to 2.4.4. - CHANGED: The firmware version check behaviour was slightly changed. The "Get Beta" checkbox will now check both the Beta and the Release channels for new version availability. Automatic scheduled checks will still only check the Release channel. - CHANGED: Layout improvements to the SNMP, Login, and Operation Mode pages (patches by Alin Trăistaru) - CHANGED: Report both the local client IP as well as the public/visible IP on the OpenVPN client page once a client is connected (same info that was already available on the VPN Status page). - CHANGED: Moved Disk spindown settings to the System page, to match with Asus382 which now offers this feature. - REMOVED: Obsolete/exotic HMAC digests for OpenVPN servers (to match with Asus' own supported list) - REMOVED: "Custom" OpenVPN authentication mode (which probably nobody used or even understood).
