Release Notes: Improves TCP throughput performance, fixes some small bugs in TCP, and fixes annoying bugs in the ARP cache and ARP packet queueing.
Release Notes: A locking problem with the sequential API was corrected.
Release Notes: A critical bug which could cause the stack to hang was fixed, as were a few smaller bugs.
Release Notes: Ability to run as a user process under Linux, and a lot of small bugfixes.
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: An experimental ARP implementation, and an experimental BSD socket API library has been added. Some bugs have been fixed.
Release Notes: Major bugfixes were made in the TCP code, the API code, and the checksum calculation. Many portability issues have been fixed. A port to the C64 was added. An lwIP mailing list was started.
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.
Release Notes: Fixes for a few bugs in the TCP congestion control, window updates, and retransmissions.
Release Notes: A new and improved directory structure, better error handling, better stability when run with very tight memory constraints, many TCP bugfixes, and more comments in the code. Also, more documentation has been added to the homepage.
