# and especially those who have found the time to port IP Filter to new
# platforms.
#
4.1.23 - Released 31 May 2007
NAT was not always correctly fixing ICMP headers for errors
some TCP state steps when closing do not update timeouts, leading to
them being removed prematurely.
fix compilation problems for netbsd 4.99
protect enumeration of lists in the kernel from callout interrupts on
BSD without locking
fix various problems with IPv6 header checks: TCP/UDP checksum validation
was not being done, fragmentation header parsed dangerously and routing
header prevented others from being seen
fix gcc 4.2 compiler warnings
fix TCP/UDP checksum calculation for IPv6
fix reference after free'ing ipftoken memory
4.1.22 - Released 13 May 2007
fix endless loop when flushing state/NAT by idle time
