Zephyr Kernel 2.0.0 (Working Draft)
|
|
####################################
|
|
|
|
We are pleased to announce the release of Zephyr kernel version 2.0.0.
|
|
|
|
Major enhancements with this release include:
|
|
|
|
* The kernel now supports both 32- and 64-bit architectures.
|
|
* We added support for SOCKS5 proxy. SOCKS5 is an Internet protocol that
|
|
exchanges network packets between a client and server through a proxy server.
|
|
* Introduced support for 6LoCAN, a 6Lo adaption layer for Controller Area
|
|
Networks.
|
|
* We added support for :ref:`Point-to-Point Protocol (PPP) <ppp>`. PPP is a
|
|
data link layer (layer 2) communications protocol used to establish a direct
|
|
connection between two nodes.
|
|
* We added support for UpdateHub which is an end-to-end solution for large scale
|
|
over-the-air update of devices.
|
|
|
|
The following sections provide detailed lists of changes by component.

|
*************
|
|
|
|
* POSIX: Fix race condition with terminated threads which had never been
|
|
scheduled by kernel. On very loaded systems it could cause swap errors.
