1		Dear XOTcl Community,
			2
			3		XOTcl 1.6.0 is available. This release provides in short:
			4		- orthogonality improvements for introspection,
			5		- more introspection methods (one can now e.g. query, into which
			6		classes a mixin class is mixed into) and
			7		- performance improvements (some methods are significantly
			8		faster. e.g. by a factor of 1000 for larger systems).
			9
			10		In addition, the XOTcl source code follows now closer the Tcl
			11		source code guidelines (e.g. variable naming), a few potential
			12		crashes have been fixed.
			13
			14		See below for more details.
			15		Best regards

			19		Announcing XOTcl 1.6.0
			20		*************************
			21
			22		We are pleased to announce the availability of XOTcl 1.6.0.
			23
			24		Major changes relative to 1.5.6 are:
			25
			26		* Provide a uniform interface to the following info subcommands
			27
			28		<class> info superclass ?-closure? ?pattern?
			29		<class> info subclass ?-closure? ?pattern?
			30		<class> info instances ?-closure? ?pattern?
			31		<class> info instmixin ?-closure? ?pattern?
			32
			33		The new option "-closure" returns the transitive set of the
			34		relation (e.g. .. info subclass -closure) returns the subclasses
			35		and the subclasses of the subclasses. For "info instances
			36		-closure" the instances of the subclasses are returned as
			37		well. For more details, please see the language reference manual.
			38
			39		In cases, where a pattern is specified, and the pattern contains
			40		meta-characters, a list of results is returned matching the
			41		pattern (like "string match"). When no matching value is found,
			42		an empty list is returned.
			43
			44		In cases, where a pattern is specified, and the pattern contains
			45		no meta-characters, a single value is returned corresponding to
			46		the specified value. The pattern is used to lookup an object or
			47		class, such it is not necessary to provide fully qualified
			48		names).  if there is no match, empty is returned.  Previously,
			49		"info superclass" and "info subclass" returned a boolean value
			50		and performed always a transitive search. Returning "" is more
			51		consistent and more in line with Tcl.
			52
			53		Note that "<class> info superclass -closure" is a replacement for
			54		"<class> info heritage", and "<class> info instances -closure"
			55		is a replacement for "<class> allinstances". The old commands
			56		will be marked as deprecated in the near future.
			57
			58		Please note, that the behavior of the match pattern has
			59		changed and is therefor not completely compatible with
			60		prior versions.
			61
			62		* New info subcommands:
			63
			64		<class> info instmixinof ?-closure? ?pattern?
			65		<class> info mixinof ?pattern?
			66
			67		These info subcommands are used to determine, into
			68		which classes a mixin class was mixed into.
			69
			70		These inverse functions of mixin and instmixin are used as well
			71		internally. These functions help to speed certain operations
			72		(e.g. superclass, or registering a mixin class) up by a factor of
			73		1000 (!)  or more, when a large number of objects exist.
			74
			75		This functionality was primarily implemented by Martin Matuska.
			76		Many thanks!
			77
			78		* Made the behavior "pattern" in the following calls identical
			79		concerning wild cards and object lookups
			80
			81		<object> mixin delete pattern
			82		<class> instmixin delete pattern
			83		<class> superclass delete pattern
			84		<object> info mixin ?pattern?
			85
			86		* Fix to preserve var traces when copying objects
			87		(Many thanks to Florian Murr for reporting)
			88
			89		* Fix problem in Tcl 8.5.* when setting variables
			90		from C (problem with Tcl_ObjSetVar2()?); many
			91		thanks to Florian Murr and Neophytos Demetriou
			92		for reporting)
			93
			94		* Improved documentation
			95
			96		* Extended regression tests
			97
			98

			100		documentation.
