libcsp 1.4, 07-05-2015
----------------------
- new: General rtable interface with support for STATIC or CIDR format
- new: CIDR (classless interdomain routing) route table format with netmasks
- new: Bridge capability
- new: Added routing table (de)serialization functions for load/save
- new: Automatic packet deduplication using CRC32 (compile time option)
- new: Autogenerated python bindings using ctypesgen
- new: Task-less operation with router invocation from external scheduler function
- api: Refactor route_if_add to csp_iflist_add
- api: Refactor route_set and friends to rtable_set
- api: Refactor csp_fifo_qos to csp_qfifo
- api: Added defined to be backwards compatible with 1.x
- interfaces: Drop packets on LOOP interface not for own address (blackhole)
- interfaces: New ZMQHUB interface (using zeroMQ over TCP)
- other: Increase stack size from 250 to 1100 for csp_can_rx_task
- other: Cleanup in csp_route.c
- other: Show incoming interface name in debug message
- other: Remove newlines from debug calls
- improvement: Reduce debug hook function complexity with valist passing
- fix: csp_sleep_ms did not work
libcsp 1.3, 07-05-2015
----------------------
- new: Split long process lists into multiple packets
- new: Added posix csp_clock.h
- new: cmp clock functions (requires that you provide csp_clock.h implementation)
- new: Added SFP (Small fragmentation protocol) for larger data chunks
- fix: csp_if_fifo example
- fix: NULL char at the end of rps
- doc: Updated mtu documentation
- other: Tested with FreeRTOS 8.0

libcsp 1.2, 25-10-2013
----------------------
- Feature release
- New: CMP service for peek and poke of memory
- New: CMP interface statistics struct is now packed
- New: Faster O(1) buffer system with reference counting and automatic alignment
- New: Thread safe KISS driver with support for multiple interfaces
- New: CSP interface struct now holds an opaque pointer to driver handle
- New: removed TXBUF from KISS driver entirely to minimize stack usage, added TX lock instead
- New: Pre-calculated CRC table .romem or PROGMEM on __avr__
- New: Added buffer overflow protection to KISS interface
- New: Allow posting null pointers on conn RX queues
- New: Lower memory usage on AVR8
- New: csp_route_save and csp_route_load functions
- New: option --disable-verbose to disable filenames and linenumber on debug
- Protocol: KISS uses csp_crc32 instead of it own embedded crc32
- Improvement: Use buffer clone function to copy promisc packets
- Bugfix: Fix pointer size (32/16bit) in cmp_peek/poke
- Bugfix: Issue with double free in KISS fixed
- Bugfix: Change rdp_send timeout from packet to connection timeout to make sending task block longer
- Bugfix: Fix conn pool leak when using security check and discarding new packets
- Bugfix: Add packet too short check for CRC32
- Bugfix: Accept CRC32 responses from nodes without CRC support
- Bugfix: Ensure csp_ping works for packets > 256 bytes
- Bugfix: Cleanup printf inside ISR functions
- Bugfix: Do not add forwarded packets to promisc queue twice
- Bugfix: Fix return value bug of csp_buffer_get when out of buffers
- Bugfix: Always post null pointer with lowest priority, not highest
- Bugfix: Add check on debug level before calling do_csp_debug, fixes #35
- Other: Export csp/arch include files
- Other: Remove the use of bool type from csp_debug
- Other: Moved csp debug functions to csp_debug.h instead of csp.h
- Other: Ensure assignment of id happens using the uint32_t .ext value of the union, quenches warning
