Release Notes: The operating system emulation layer was redesigned to make porting easier. Better control over TCP output buffers was added. Locking problems in buffer management and bugs in the sequential API have been fixed. A problem potentially causing IP forwarding to leak memory was fixed. Documentation was added.
Release Notes: A new memory subsystem (instead of allocating memory from a shared heap, objects that are frequently allocated and deallocated are kept in memory pools), support in the memory and buffer subsystems for 4- and 2-byte aligned memory, and testing under the RTXC real-time kernel.
