[RELEASE]
Version: 2.1.1
Date: 2008-03-06
[DESCRIPTION]
This is a bugfix release.

[DESCRIPTION]
Non-shared copying of dfa was broken (matters only for parallel execution).

[ENTRY]
Module: kernel
What:   bug
Rank:   minor
[DESCRIPTION]
Made the constructor of Reflection::Var explicit, otherwise overloading for
output stream operators does not work as expected.


[RELEASE]
Version: 2.1.0
Date:    2008-02-29
[DESCRIPTION]
This release makes two essential contributions: a partly
reimplemented kernel that is faster, is simpler, and uses less
memory and lots of small and not so small fixes. This release is
the first release where really everything that we can test
(rather than everything that we initially believed to matter) has
been systematically tested. So, better switch now to 2.1.0!

Apart from that, the value range for variables has been increased
(basically, 32 bits minus three values, so that is 32 bits), the reflection 
API is now fully functional and no longer considered experimental, and we have
the usual small additions.


[ENTRY]

[ENTRY]
Module: other
What:   new
Rank:   major
[DESCRIPTION]
The serialization library now contains a registry of all the Gecode post 
functions. This makes interfacing to Gecode much easier. The registry is 
automatically generated from the post functions defined in gecode/int.hh and 
gecode/set.hh.

[ENTRY]
Module: kernel
What:   change
Rank:   minor
[DESCRIPTION]
Cleaned up reflection. Unreflection is now part of the kernel instead of the 
serialization library. Branchings now provide a human-readable description of 
a BranchingDesc. The name function of a Propagator has been renamed to ati 
(actor type identifier). All reflection is now const where possible. 
Unreflection of variables now checks dynamically that the variable types 
match. Unreflection of propagators checks the number of arguments. A 
tutorial-style section on reflection has been added to the documentation.

[ENTRY]
Module: set
What:   change
Rank:   major
[DESCRIPTION]
The limits for set variables have been moved from Limits::Set to
Set::Limits.

The range of set variables has been adapted to the range of
integer variables.  For example, on a standard machine
(regardless of 32 or 64 bits), a set can hold values from -2^30+2
to 2^30-2, its maximum cardinality therefore is 2^31-3.

[ENTRY]
Module: int
What:   change
Rank:   major
[DESCRIPTION]
The limits for set variables have been moved from Limits::Set to
Set::Limits.

The range of integer variables have been extended by one bit. For
example, on a standard machine (regardless of 32 or 64 bits), the
largest possible integer value for an integer variable is 2^31-2,
the smallest -2^31+2. With other words, only the integer values
2^31-1, -2^31, and -2^31+1 are missing from the two-complement
representation (and we will never use these values for the sake
of mental sanity. We promise.).

[ENTRY]
Module: int
What:   bug
Rank:   minor
[DESCRIPTION]
Distinct with integer offsets checks accurately for overflow now.

[ENTRY]
Module: int
What:   performance
Rank:   minor
[DESCRIPTION]
Boolean variables consume 20% less memory.

[ENTRY]
Module: kernel
What:   change
Rank:   major
[DESCRIPTION]
Only stable and non-failed spaces can be cloned, otherwise
Space::clone raises an exception. This makes cloning and
propagation fully orthogonal. To emulate the old behavior, just
execute Space::status before Space::clone.

[ENTRY]
Module: kernel
What:   change
Rank:   minor
[DESCRIPTION]
The number of propagators and branchings can be accurately
retrieved from both failed and non-stable spaces.

[ENTRY]
Module: examples
What:   new
Rank:   minor
[DESCRIPTION]
Added an example that interprets a JavaScript program and runs a search of the 
model that the program encodes. This is an example of how to use the 
JavaScript interpreter. A simple JavaScript model for n-Queens has been added, 
too.

[ENTRY]
Module: kernel
What:   new
Rank:   minor
[DESCRIPTION]
A generic variable class has been added that can be used for interfacing. It 
can store arbitrary Gecode variables (e.g. IntVar and SetVar), and cast them 
back using a run-time type check. The update, reflection, and output 
operations are implemented through the reflection registry.

[ENTRY]
Module: other
What:   new
Rank:   major
[DESCRIPTION]
(De-)Serialization to and from JavaScript added.

[ENTRY]
Module: other
What:   change
Rank:   major
[DESCRIPTION]
Both the cost and propagate function of a propagator take the
current modification event delta as input. Likewise,
retrieving the modification event for a particular View must use
the static function View::me with the passed
modification event delta. Again, this feature committed the kernel to a
particular implementation which might not be available in the
future.

[ENTRY]
Module: kernel
What:   change
Rank:   minor
[DESCRIPTION]
Views and variables do not any longer reveal whether they have
been modified: this feature committed the kernel to a particular
implementation which might not be available in the future.

[ENTRY]
Module: example
What:   new
Rank:   minor
[DESCRIPTION]
Simple Singleton Arc Consistency pre-processing has been added as an
optional step for examples.

[ENTRY]
Module: kernel
What:   change
Rank:   major
[DESCRIPTION]
The kernel has undergone some cleanups and improvements (much of
it got actually reimplemented):
 - Automatically generated stubs for variable implementations are directly
   inlined into the kernel. This improves performance, but more
   importantly, lifts some limits on the number of variables. Now, the
   only limit is that the sum of the ceiling of the logarithms of the 
   number of modification events of all variables does not exceed 32
   (as an estimate, the kernel now can handle around 10 to 16 variable
   types). Moreover, if the need for more variable types arises this is 
   straightforward to do.
 - The addition of new variable types for users has been simplified.
 - The main propagation loop has been entirely rewritten (much much simpler).
   Now, the kernel does not optimize any longer for the case that a
   variable is modified more than once during propagator execution.
   While this changes the asymptotic complexity, it reduces the propagator
   execution overhead by up to 30%. And a propagator is still free
   to make sure that a variable is modified only once (many propagators
   do that already).
 - Variable implementations became smaller by one word. Now variable
   implementations are optimal in the sense that no additional memory
   is needed for cloning or book-keeping, the memory required for 
   propagation is sufficient.
 - Spaces have lost some weight as memory for datastructures only used
   during cloning or propagation are shared (saves some 25% of memory
   per space).

[ENTRY]
Module: kernel
What:   change
Rank:   major
[DESCRIPTION]
Propagator modification events have been renamed to modification event
deltas (because that is what they are).

[ENTRY]
Module: kernel
What:   change
Rank:   minor
[DESCRIPTION]
To not confuse variable implementations with variables, variable
implementations are now always called VarImp, and not Variable.

[ENTRY]
Module: gist
What:   new
Rank:   major
[DESCRIPTION]
The %Gecode Interactive Search Tool (Gist), a Qt-based graphical search 
engine, is now part of the main %Gecode distribution. It is currently included
as an experimental beta preview and may not be completely stable yet.

negative array indices.



[RELEASE]
Version: 2.0.0
Date:    2007-11-14
[DESCRIPTION]
As witnessed by the version number change, this is a major
release with too many changes, fixes, and additions to mention
them all: please consult the changelog.

The highlights are:
 - New propagators: channeling between Integer variable and array
   of Boolean variables, circuit, table constraint (extensional),
   incremental regular constraint (extensional), incremental
   Boolean linear constraints
 - Boolean variables have a dedicated implementation: twice as
   fast, half the memory
 - Advisors for incremental propagation (see: Lagerkvist,
   Schulte, Advisors for Incremental Propagation, CP 2007)
 - Many crucial performance and scalability improvements: memory
   management, memory footprint of propagators
 - Many cleanups and more documentation, many new examples
 - New set variables with complete domain representation
   (CpltSetVar) [experimental]
 - A reflection API to query spaces about their propagators
   [experimental]

The features marked as experimental are all functional, but might
be revised in the next releases.
 
As %Gecode 2.0.0 is a major release, you might have to adapt your
programs:  \ref PageHowToChange_2 "How to Change to Gecode 2.0.0".

The structure of includes has been drastically
simplified. Support for iterators ("gecode/iter.hh") is
automatically included with integers ("gecode/int.hh") and sets

this is included in "gecode/kernel.hh").

[ENTRY]

right-hand sides use constant time propagators whenever
appropriate (linear time with less overhead and memory for
propagators with few variables).

[DESCRIPTION]
Added advisors as an abstraction for incremental propagation:
advisors are executed for their propagator whenever their view
changes. Advisors, when not being used, add one word of overhead
to each variable and slow down the system in the worst case by
less than 1%. In average, no slowdown can be observed.

[DESCRIPTION]
The memory management policies have been completely reworked. Now
memory requests are much more regular. Hence, memory is much more
likely to be returned to the operating system. Furthermore, the
flush member functions for actors have been removed (they were
unneeded) and actors and spaces now have allocated member
functions for returning how much memory is allocated by a space.

Moreover, the memory reported by some propagators has been
ignored. Note that this flaw did not affect the benchmark figures
on the %Gecode webpage.

[ENTRY]
Module:	int
What:	change
Rank:	major
[DESCRIPTION]
Boolean variables (and hence Boolean views) do not any longer
share the implementation with integer variables. That has the
following consequences:
- Boolean variables are not any longer integer variables. The same
  holds true for arrays of variables.
- All constraints that make sense for both Boolean and integer
  variables have post functions that support both integer and
  Boolean variables.
- Memory for Boolean variables is reduced by 50% and performance
  increases in problems with many Boolean variables by up to 50%.

The finite set selection propagators accept an additional

All Boolean constraints got a new and regular interface. Rather
than providing different post functions for the different

better performance and less memory use.

[DESCRIPTION]
The way how propagators report subsumption and partial fixpoints
has changed. Now, a propagator must first call dispose (which
then cancels subscriptions and possibly frees external resources)
and only then can return that the propagator is subsumed. For
that purpose a new function Gecode::ES_SUBSUMED has been
defined. Likewise, ES_FIX_PARTIAL and ES_NOFIX_PARTIAL are
functions rather than member functions of Gecode::Propagator. The
benefit is that this saves memory and is more efficient.

Rank: 	major
[DESCRIPTION]
Branch-and-bound search now interleaves recomputation with adding
bounding constraints. This can prune the search tree much
earlier: instead of recomputing many nodes from the same copy
node and then adding a constraint that fails all these nodes, it
might be possible to already fail the copy node directly. In
principle, the difference can be exponential, however for
examples we tried the effect is minor.

[ENTRY]
Module: kernel
What: 	bug
Rank: 	minor
[DESCRIPTION]
Now commits can be interleaved with adding new constraints during
batch recomputation. This also entails that commit does not raise
an exception when applied to an already failed space (it is
simply ignored). The bug could not be observed (unless you did
some very fancy search engines yourself) and one could actually
see it as an extension.

[DESCRIPTION]
Global cardinality changed to non-staged version.  Further
inference for cardinality variables added.  Parts of the graph
structure for the domain-consistent propagator have been revised
so as to avoid unnecessary propagation in case of fixed
cardinalities and to allow better staging for the
propagator. Revision of propagation for fixed cardinalities has
also been applied to bounds-consistent propagator.
