AsusWrt-Merlin Firmware 3.0.0.4.378.50.0 for RT-AC66U Description

The AsusWrt-Merlin firmware was developed with the primary goal of boosting the original ASUS firmware, fix bugs and also add new improvements. This package includes a customized firmware targeted at ASUS routers that brings various changes without modifying the interface of the original firmware.

IMPORTANT:

- You must do a factory default reset, and manually configure your setting if coming from a version older than 378.50. Failure to do so can lead to various issues with wifi, OpenVPN, and the new AC68U bootloader.
- Please read this changelog, especially the changes related to jffs, user scripts/config and OpenVPN in the previous 378.50 betas.

Changes:

- NEW: Merged with Asus GPL 378_4129 code.
- CHANGED: Reverted back to vsftpd 2.x, as 3.0.2 doesn't work properly on MIPS architectures (and possibly other particular scenarios as well).
- CHANGED: Added warning to the DDNS page if you set the type to Custom and either JFFS or custom script support isn't enabled
- FIXED: A few unescaped quotes in the French dict breaking VPN pages
- FIXED: MAC list would get corrupted when removing and re-adding entries on the MAC filter list
- FIXED: AC68U CFE update wasn't written to flash due to permission issues
- FIXED: Static Key field wasn't visible when using HMAC authentication
- FIXED: syslogd was always enforcing the -S switch
- FIXED: When setting a static DHCP from the networkmap, the user-entered name wouldn't be used. Now it gets used, and we rely on the rc daemon to properly handle it if it's not a valid hostname (it will simply not provide it to dnsmasq's static name list).

Installation Notes:

- This custom firmware can be applied like any regular update.
- You should not need to reset to factory defaults.
- You can revert back to an original ASUS firmware at any time.
- Do not load a saved copy of your settings.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
