some preparations for v2.1.0 release

FEATURES

@@ -3,7 +3,7 @@ lwIP is a small independent implementation of the TCP/IP protocol suite targeted
 The focus of the lwIP TCP/IP implementation is to reduce resource usage while still having a full scale TCP. This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM.
 
 Main features include:
-- Protocols: IP, IPv6, ICMP, ND, MLD, UDP, TCP, IGMP, ARP, PPPoS, PPPoE, 6LowPAN (via IEEE 802.15.4, BEL or ZEP; since v2.1.0)
+- Protocols: IP, IPv6, ICMP, ND, MLD, UDP, TCP, IGMP, ARP, PPPoS, PPPoE, 6LowPAN (via IEEE 802.15.4, BLE or ZEP; since v2.1.0)
 - DHCP client, stateless DHCPv6 (since v2.1.0), DNS client (incl. mDNS hostname resolver), AutoIP/APIPA (Zeroconf), SNMP agent (v1, v2c, v3 (since v2.1.0), private MIB support & MIB compiler)
 - APIs: specialized APIs for enhanced performance & zero copy, optional Berkeley-alike socket API
 - Extended features: IP forwarding over multiple network interfaces
