Contiki 2.6 Released

The Contiki team is happy to announce the release of Contiki 2.6. This release brings several improvements to core Contiki networking components, such as the IPv6 RPL routing protocol and Erbuim, a new CoAP implementation, as well as a set of new platforms (cc2530, exp5438, wismote), and several new Cooja simulation platforms (exp5438, wismote, z1). The release also adds new Contiki applications, such as the Antelope low-power database manager and a new HTTP server for web services. Sleepy router support has also been extended to new platforms (STM32w).
