CHANGES

+v3.1 - Sun Aug 24 21:39:43 ART 2014
+
+- Fixed ICMPv6 checksum error on serialization.
+
+- Fixed empty domain name encoding on DNS.
+
+- Changed the build system to CMake.
+
+v3.0 - Thu Aug  7 21:39:09 ART 2014
+
+- Timestamps can now be constructed from std::chrono::duration.
+
+- Packets can now be constructed from a PDU pointer and take ownership
+of it.
+
+- All protocols now set the next layer protocol flag, regardless if 
+it was already set. This was not done in some protocols, 
+like EthernetII, and as a consequence if the network layer protocol
+was replaced by other, the packet would be serialized incorrectly.
+
+- Fixed invalid parsing of some unknown DNS records.
+
+- Fixed unaligned memory accesses that were not supported under
+ARMv4 and ARMv5.
+
+- Added BaseSniffer::set_extract_raw_pdus.
+
+- Reduced minimum automake version to 1.11.
+
+- Added Utils::to_string(PDU::PDUType).
+
+- Fixed error compilations on Windows.
+
+- Fixed ICMPv6 checksum calculation.
+
+- Added method in IP and TCP to emplace an option (C++11 only).
+
+- Added small option optimization to PDUOption.
+
+- Fixed error compilation on RSNInformation.
+
+- Renamed ICMP::check to ICMP::checksum.
+
+- Added Sniffer support to set interface to promiscuous mode.
+
+- TCPStreamFollower now handles overlapping fragments correctly.
+
+- Fixed bugs in TCPStreamFollower which didn't allow it to follow
+stream correctly.
+
+- TCPStreamFollower now doesn't clear its state after every call to
+TCPStreamFollower::follow_streams.
+
+- Added IPv6 flag check to pdu_flag_to_ip_type.
+
+- Added DHCP::hostname to extract the hostname options.
+
+- Removed extra qualifier on SessionKeys::decrypt_unicast which 
+produced compilation errors on some platforms.
+
+- PacketSender::send now uses PDU::matches_flag to match specific
+PDU types.
+
+- Removed 'no newline at end of file' warnings.
+
+- Fixed bug when calling BIOCIMMEDIATE on *BSD.
+
+- Fixed bug on PacketSender::send_recv which didn't work under *BSD.
+
+- Fixed bug triggered by not including the string header.
+
+v2.0 - Thu Jan 23 11:09:38 ART 2014 
+
+- DNSResourceRecord was removed. Now DNS records are added using 
+DNS::Resource.
+
+- tins.h now includes ppi.h.
+
+- Done significant improvements in the speed of DNS parsing.
+
+- Added PDUOption<>::to<> which converts a PDUOption to a specific type.
+
+- Layer 3 packets sent using PacketSender::send_recv for which the 
+answer is a different PDU type.
+
+- ICMP::gateway now uses IPv4Address.
+
+- Added support for ICMP address mask request/reply.
+
+- Fixed bug in PacketSender when using send_recv and a layer 2 PDU. The 
+interface in which the packet was sent was not the default_interface 
+set when the sender was constructed.
+
+- IP packets sent using PacketSender::send_recv now match ICMP 
+responses.
+
+- Added support for ICMP timestamp request/reply packets. 
+ICMP::matches_response now works with these types of packets as well.
+
+- Added support for reassembling of fragmented IP packets via the
+IPv4Reassembler class.
+
+- Fragmented IP packet's inner_pdu PDUs are not decoded now.
+
+- Added 1000ms as the default read timeout used when calling 
+pcap_open_live. Added BaseSniffer::set_timeout to modify this parameter.
+
+- Added the --disable-dot11 configure switch.
+
+- Added support for IPSec.
+
+- Fixed bug triggered when ifaddrs::ifa_addr was null in 
+NetworkInterface::addresses.
+
+- Added another overload of Utils::route_entries which returns the
+result either than storing it in a parameter.
+
+- Added ARP monitor, WPS detector, DNS queries sniffer and DNS spoofer 
+examples.
+
+- Added another Sniffer constructor which doesn't expect the maximum
+capture size.
+
+- Added tins_cast as a replacement for dynamic_cast on PDUs.
+
 v1.2 - Mon oct  7 23:33:49 ART 2013
 
 - Added BaseSniffer::begin and BaseSniffer::end.

+libtins
+=======
+
+libtins is a high-level, multiplatform C++ network packet sniffing and 
+crafting library. 
+
+Its main purpose is to provide the C++ developer an easy, efficient, 
+platform and endianess-independent way to create tools which need to 
+send, receive and manipulate specially crafted packets. 
+
+In order to read tutorials, examples and checkout some benchmarks of the
+library, please visit:
+
+http://libtins.github.io/
+
+## Compiling ##
+
+[libtins](http://libtins.github.io/) depends on 
+[libpcap](http://www.tcpdump.org/) and 
+[openssl](http://www.openssl.org/), although the latter is not necessary 
+if some features of the library are disabled.
+
+In order to compile, execute:
+
+```Shell
+# Create the build directory
+mkdir build
+cd build
+
+# Configure the project. Add any relevant configuration flags
+cmake ../
+
+# Compile!
+make
+```
+
+Note that by default, only the shared object is compiled. If you would
+like to generate a static library file, run:
+
+```Shell
+cmake ../ -DLIBTINS_BUILD_SHARED=0
+```
+
+The generated static/shared library files will be located in the 
+_build/lib_ directory.
+
+libtins is noticeable faster if you enable _C++11_ support. Therefore, 
+if your compiler supports this standard, then you should enable it. 
+In order to do so, use the _LIBTINS_ENABLE_CXX11_ switch:
+
+```Shell
+cmake ../ -DLIBTINS_ENABLE_CXX11=1
+```
+
+If you want to disable _WPA2_ decryption support, which will remove 
+openssl as a dependency for compilation, use the 
+_LIBTINS_ENABLE_WPA2_ switch:
+
+```Shell
+cmake ../ -DLIBTINS_ENABLE_WPA2=0
+```
+
+If you want to disable IEEE 802.11 support(this will also disable 
+RadioTap and WPA2 decryption), which will reduce the size of the 
+resulting library in around 20%, use the _LIBTINS_ENABLE_DOT11_ switch:
+
+```Shell
+cmake ../ -DLIBTINS_ENABLE_DOT11=0
+```
+
+## Installing ##
+
+Once you're done, if you want to install the header files and the 
+shared object, execute as root:
+
+```Shell
+make install
+```
+
+This will install the shared object typically in _/usr/local/lib_. Note
+that you might have to update ldconfig's cache before using it, so 
+in order to invalidate it, you should run(as root):
+
+```Shell
+ldconfig
+```
+
+## Examples ##
+
+You might want to have a look at the examples located  in the "examples"
+directory. The same samples can be found online at:
