Version 1.0.0 change log:
- Added Kinetis (ARM Cortex-M4) - MK60N512 support.
- Added support of the IAR Embedded Workbench for ARM compiler, version 6.1.
- Added standard FNET demo applications for the TWR-K60N512 board, including the FNET on-chip Bootloader.
- Added support of little-endian platforms, defined by FNET_CFG_CPU_LITTLE_ENDIAN.
- Added set of functions and macroses that convert values between host and network byte order (like fnet_ntohs(), fnet_htonl() and etc. ).
- Added common on-chip Flash memory driver for Kinetis (FTFL) and ColdFire (CFM) modules.
- Added support of 16 bits and 24 bits addressing in the S-record file format for the FNET Bootloader.
- Added common FEC driver for Kinetis and ColdFire platform.
- Improved response of the Telnet server.
- Added the fnet_telnet_close_session() function, which closes the currently active session of the Telnet Server.
- Added the fnet_println() function that prints formatted text to the stream and terminates it by line separator string.
- Added fnet_serial_flush() function that sends/flushes data from the internal stream buffer to the stream client, it has meaning only for buffered streams.
- Applied optimized version of the IP checksum calculation and the fnet_memcpy() function.

Version 0.9.3 change log:
- Fixed stuck issue that may occur during receiving of broadcast UDP datagrams.
- Fixed buffer corruption issue that may occur when the internal static heap buffer has relatively small size.
- Improved stability of nebuf. management.
- FEC Frame buffers and descriptors are allocated statically (before in internal heap). Existing applications should reduce value of the FNET_CFG_HEAP_SIZE in user-configuration file by the value that equals summary size of buffers statically allocated in Ethernet driver. Roughly [NEW_VALUE]=[OLD_VALUE]-(FNET_CFG_MCF_ETH_TX_BUFS_MAX+FNET_CFG_MCF_ETH_RX_BUFS_MAX)* FNET_CFG_ETH_MTU.
- Renamed FNET_CFG_MCF_SERIAL_PORT_DEFAULT to FNET_CFG_CPU_SERIAL_PORT_DEFAULT.
- Added the FNET_CFG_TELNET_SOCKET_BUF_SIZE user-configuration option that defines size of the socket RX & TX buffer used by the Telnet server.
- Added OS folder where it will be placed all OS-specific code.
- Added uCOS-II specific ISR handler.
- Added FNET_CFG_OS and FNET_CFG_OS_operation_system_type set of user-configuration options that define a currently used OS. For this moment there is FNET_CFG_OS_UCOSII only.
- Added "Free heap" information to the Shell-example "info" command.
- Other minor changes/fixes.... read more

- Added the FNET_CFG_SOCKET_TCP_MSS user-configuration option that defines the default value of the TCP_MSS socket option. By default the selection of the MSS is automatic and is based on the MTU of the outgoing interface. It is done to assist in avoiding of IP fragmentation at the endpoints of the TCP connection.
- Added the FNET_CFG_SHELL_HELP_FORMAT user-configuration option that defines the format of the command-shell help message, that is used by the fnet_shell_help() function.
- Added the FNET_CFG_TELNET_SHELL_ECHO user-configuration option that defines the Echo in the Telnet shell.
