Revision history for Perl extension Nmap::Parser::XML.
The latest version can be found at:

http://search.cpan.org/~apersaud/Nmap-Parser-XML/

Changes for 0.69
	- new utility script : scan_host.pl
	- added EXAMPLES seciton in documentation
	- parses new 'version', 'extrainfo', and 'product'
		att from service tag (3.40+)
	- added *_service_version to *::Host
	- added xml_version to *::ScanInfo
	- more error prevention mechanisms
	- added os_osfamily, os_gen, os_vendor, os_type added
	- added OSINFO filter
	- ::ScanInfo::scan_types does not return number of scan types in scalar
		format. It will always return an array containing the scan
		types.
	- osfamily does not return the actual string (comma delimited), it always
	returns an array of os matches.
	- DEPRECATED: tcpsequence, ipidsequence, tcptssequence
		now use:
		tcpsequence_class, tcpsequence_values, tcpsequence_index
		ipidsequence_class, ipidsequence_values
		tcptssequence_class, tcptssequence_values


Changes for 0.68
	- Licensing changes, now under GPL
	- added signatures for wireless access points (wap)
	- added os_match shortcut function
	- Problem with Makefile.PL, didn't pass correct dependencies.
	- tcp_port_state() and udp_port_state() return the state of the port
		when passed a port number.
	- Sorted port order when using tcp_ports and udp_ports
	- extraports tag parsing. It is also set up as a filter 'extraports'
		filtering. Added extraports_state and extraports_count to
		Nmap::Parser::XML::Host class.
	- Added and fix some documentation
	- tcp_ports and udp_ports can take a parameter to filter what port list
		you wish to receive. It selects states based on port content
		state tag: filtered, closed, or open
        - previous versions (0.64 or earlier) of the parser, no arguments
	to tcp_ports and udp_ports would return the whole hashref of all the
	ports, this is now deprecated. Use the newly created functions
	tcp_service_name, tcp_service_proto, tcp_service_rpcnum,
	udp_service_name, udp_service_proto, and udp_service_rpcnum.
	- changed default filter for solaris to include 'sun' and not 'sunos'
	- more example scripts
	- no more wantarray usage for tcp_ports and udp_ports
	- more test cases

Changes for 0.66
	- added short-cut function hostname() to return first hostname
	- added preliminary callback functionality (for registering events).
		This includes register_host_callback, and reset_host_callback
	- tcp_ports and udp_ports do not return hashref of all ports, only if
		passed a port number as an argument.The argument must be a port
		number.	They default to returning an array of port numbers.
	- added short-cuts tcp_ports_count and udp_ports_count functions
	- added tcp_service_proto and udp_service_proto
	- added tcp_service_rpcnum and udp_service_rpcnum
	- POD fixes.
	- speed improvements

Changes for 0.64
	- nmaprun filter bug fixed
	- important documentation changes

Changes for 0.63
	- added vendor to os_class
	- fixed division by zero on one of the efficiency test.
	- it now checks to make sure Time::HiRes is installed before
		performing tests.
	- minor warning problems removed on Win32 systems.

Changes for 0.62
	- stable release with all new changes.

Changes for 0.6_4
	- changes to parse filter tags. All previously called PARSE_* have
		the PARSE_ removed from them. Ex: PARSE_OSFAMILY is now
		OSFAMILY.
	- osclass tag added.
	- a bug found with the sequences is fixed
	- making use of ignore_elts to save when creating objects
	- parse_filters completly excludes tags that you decide not to parse.
		Much faster parsing and memory usage efficiency. efficiency.t
		tests this benchmark to make sure that the twig parser does not
		do any work it doesn't have to.
	- permanently excluding some static tags using ignore_elts.
	- added SCANINFO filter.

Changes for 0.60_3
	- os_port_used, now can return the open or closed port used in OS
		detection depending on the given parameter.

Changes for 0.60_2
	- Bug #2968:
		fixed bogus 'use 5.008' in Makefile.PL (runs on 5.6 also)
		instead using 5.004
		fixed minor warnings when compiling with -w
		added 'use warnings' to _methods test

Changes for 0.60_1
	- fixed a bug with the test script (finding test file)
	- made a separate test to test the actual method existance
	- portability when running the tests using File::Spec.

Changed for 0.60
	- better memory management using twig_roots
	- some bugs with output types and filters
	- generic_os and all references are now refereed to as 'osfamily'
		I thought it better resembles what it stands for.
	- fixed some documentation problems
	- parse_filter_* have been replaced with parse_filters(), which
		can enable multiple different filters through a hashref.
		Filters available:
		ONLY_ACTIVE, PARSE_OSFAMILY, PARSE_UPTIME, PARSE_PORTINFO,
		PARSE_SEQUENCES
	- added parse information of
		tcpsequence, ipidsequence, tcptssequence
	- additions to Nmap::Parser::XML::Host methods
		tcpsequence, ipidsequence, tcptssequence

Changes for 0.50
	- faster loading module
	- added more documentation
	- minor speed improvements
	- added methods to Nmap::Parser::XML
		parse_filter_generic_os($bool) (see doc)
	- renamed only_active() to parse_filter_status($bool) (see doc)
	- Nmap::Parser::XML::Host
		changed hostnames() to take a value a number (see doc)
		changed os_matches() to take a value a number (see doc)

Changes for 0.40
	- added new package called ScanInfo (Nmap::Parser::XML::ScanInfo
        	this contains methods that make it easier to access the
        	scan information
	- added new package called Host (Nmap::Parser::XML::Host),
		which makes it easier to access values for each of the
		hosts found. See documentation.
		Host trees are now full of these *::Host objects.
	- fixed minor bugs with parsing the xml files.
	- some memory usage improvments.

Changes for 0.01
	- original version; created by h2xs 1.22 with options
		-X -n Nmap::Parser::XML
