 ## Main Features
 * support many IP blocklist sources (free for private usage, for commercial use please check their individual licenses):
 * zero-conf like automatic installation & setup, usually no manual changes needed
-* supports six different download utilities: uclient-fetch, wget, curl, aria2c, wget-nossl, busybox-wget
+* supports four different download utilities: uclient-fetch, wget, curl, aria2c
 * Really fast downloads & list processing as they are handled in parallel as background jobs in a configurable 'Download Queue'
-* provides 'http only' mode without installed ssl library for all non-SSL blocklist sources
 * full IPv4 and IPv6 support
 * ipsets (one per source) are used to ban a large number of IP addresses
 * supports blocking by ASN numbers
 * supports blocking by iso country codes
 * supports local white & blacklist (IPv4, IPv6 & CIDR notation), located by default in /etc/banip/banip.whitelist and /etc/banip/banip.blacklist
-* auto-add unsuccessful ssh login attempts to local blacklist (see 'ban_autoblacklist' option)
+* auto-add unsuccessful ssh login attempts to 'dropbear' or 'sshd' to local blacklist (see 'ban_autoblacklist' option)
 * auto-add the uplink subnet to local whitelist (see 'ban_autowhitelist' option)
 * per source configuration of SRC (incoming) and DST (outgoing)
 * integrated IPSet-Lookup
 * integrated RIPE-Lookup
 * blocklist source parsing by fast & flexible regex rulesets
 * minimal status & error logging to syslog, enable debug logging to receive more output
-* procd based init system support (start/stop/restart/reload/status)
+* procd based init system support (start/stop/restart/reload/refresh/status)
 * procd network interface trigger support
-* automatic blocklist backup & restore, they will be used in case of download errors or during startup in backup mode
-* 'backup mode' to re-use blocklist backups during startup, get fresh lists via reload or restart action
+* automatic blocklist backup & restore, they will be used in case of download errors or during startup
 * output comprehensive runtime information via LuCI or via 'status' init command
 * strong LuCI support
 * optional: add new banIP sources on your own
 
 ## Prerequisites
-* [OpenWrt](https://openwrt.org), tested with the stable release series (18.06) and with the latest snapshot
+* [OpenWrt](https://openwrt.org), tested with the stable release series (19.07) and with the latest snapshot
 * a download utility:
-    * to support all blocklist sources a full version (with ssl support) of 'wget', 'uclient-fetch' with one of the 'libustream-*' ssl libraries, 'aria2c' or 'curl' is required
-    * for limited devices with real memory constraints, banIP provides also a 'http only' option and supports wget-nossl and uclient-fetch (without libustream-ssl) as well
+    * to support all blocklist sources a full version with ssl support of 'wget', 'uclient-fetch' with one of the 'libustream-*' ssl libraries, 'aria2c' or 'curl' is required
 
 ## Installation & Usage
 * install 'banip' (_opkg install banip_)
 * at minimum configure the needed IP blocklist sources, the download utility and enable the banIP service in _/etc/config/banip_
-* control the banip service manually with _/etc/init.d/banip_ start/stop/restart/reload/status or use the LuCI frontend
+* control the banip service manually with _/etc/init.d/banip_ start/stop/restart/reload/refresh/status or use the LuCI frontend
 
 ## LuCI banIP companion package
 * it's recommended to use the provided LuCI frontend to control all aspects of banIP
