+--- Changelog ---
+
+2.05: Added ScatterSearch (real-valued), BinaryScatterSearch, and the Bayesian Optimization Algorithm (thanks
+ 			to Alexander Seitz) to the base package. Added JobList and some statistical measures. Requires to put
+ 			the JSC package on the class path for Mann-Whitney test.
+
+2.046: Adaptions to the MatlabInterface: explicit data types are used now, added integer problem support.
+ 			Additional Integer operators: segment-wise mutation and crossover. Added an abstraction over individual
+ 			initialization methods. Added the ERPStarter class which is an example for running a csv-configured 
+ 			optimization. Some bug-fixes and clean-ups.
+
+2.045: Added MOOCMAES (de Paly); compatibility with Java 1.5 (Draeger); Revision of the statistics class
+ 			with improved pipelining of data (InterfaceAdditionalPopulationInformer); improved FunctionArea
+ 			concerning history, labels, legend and graph coloring; improved StringSelection; restructured
+ 			Terminators, additional ParetoMetricTerminator. Further bugfixes and clean-ups.
+
+2.043: Added proper Population equality predicate.
+
+2.042: Some bugfixes. Removing dependency on sun.beans.editors, replaced non-free jpeg-codec. There should
+ 			be no more problems on OpenJDK. Added a simple initialization range, especially for use from Matlab.
+ 			Some restructurings (RNG and Mathematics is now in eva2.tools.math). Some cleanup.
+
+2.040: Several updates: The clustering interface has been changed for easier implementation of adaptive clustering
+ 			methods. The GradientDescentAlgorithm has been updated and some benchmark problems been made derivable.
+ 			The ClusterBasedNiching algorithm has been slightly restructured updated according to the new clustering.
+ 			An additional clustering method is included: nearest-best clustering with dynamic adaption of niche radius.
+ 			Some changes to (text) statistics: they are now printed regarding the full solution set instead of the
+ 			last population. The Population field "size" is now termed "targetSize" to avoid misunderstandigs. Populations
+ 			can be initialized using a Random Latin Hypercube sampling. Some basic console options are recognized:
+ 			EvA2 can be started without splash screen and even without GUI. If configuration file is given which was 
+ 			earlier saved from the GUI, the thus defined optimization run is then processed automatically by EvA2. 
+
+2.036: New graph selection mode for statistic plots: every property may be selected independently.
+ 			A simple plot legend is produced in the graph window, which can be deactivated.
+
+2.035: Reactivated some of the model-based functionality within the GO framework. Minor bugfixes.
+
+2.034: Adding a generic parameter control method for optimizers, currently used by PSO to adapt inertness depending
+ 			on EvaluationTerminator or GenerationTerminator instances defining the number of function evaluations.
+ 			The new package is eva2.server.go.operators.paramcontrol.
+ 			A Population may now be ordered by a specific fitness criterion, employed, e.g., by Nelder-Mead-Simplex.
+
+2.033: There was an interesting problem with the Matlab-Interface, which just hung up after extensive optimization
+ 			loops, yet only if Matlab was started without X-forwarding (which is necessary for qsub, e.g.).
+ 			Debugging was tedious, since the debugging using System.out. itself caused threading deadlocks. The 
+ 			problem showed up to be with System.out itself. Whatever Matlab does with that stream, it does it differently
+ 			depending on the X-forwarding option. More specifically, the text written to System.out when X-forwarding
+ 			is not available seems to never show up (as opposed to being printed to the console when X-forwarding is on)
+ 			and silently fill up the JVM-memory. I havent the faintest idea why there havnt been OutOfMemory exceptions
+ 			earlier or whether and how the deadlocks have to do with it. 
+ 			The ingenious solution was: dont print anything to System.out, which is now done at verbosity 0.
+
+2.032: Some cosmetics, e.g. to AbstractEAIndividualComparator and older MOCCO classes. 
+
+2.031: Some updates to the OptimizerFactory. Review of the MatlabInterface with adding an own options structure.
+ 			Better access to the EvAClient, which now may have a RemoteStateListener added monitoring the optimization run.
+
+2.030: Added an EnumEditor to access enums easily through the GUI, which will replace SelectedTags sometimes.
+ 			IPOP-ES and RankMuCMA mutator have been added lately (wow!).
+ 			Cleaned up the IndividualInterface and reduced the usage of InterfaceESIndividual. This
+ 			means that, e.g., that DE and PSO now also work on GAIndividualDoubleData. Because this 
+ 			requires much time for transcoding, however, this is not useful by itself. Yet it could be
+ 			interesting for combined individuals composed of two data types. 
+ 			Cleaned up MutateXXDefault to a single MutateDefault, too. DE may now do range checking.
+ 			The "Description" button has made space for a "Show Solution" button. The Rank-Mu-CMA was improved
+ 			to use a CMAParameterSet which is associated with populations and not static any more.
+ 			Included Nelder-Mead-Simplex and CMA-ES as post processing methods.
+
+2.029: Tuned the 2d-graphs which now paints quicker and changes size depending on the
+			surrounding plot window. Added a preloader-thread to accelerate the GUI at starting time.
+
+2.028: Tuned the Population to sort only when necessary on calls to getBestN... Added StatisticsDummy.
+			Slightly tuned SimpleProblemWrapper to call initProblem of simple problems if available.
+
+2.027: Renamed SetData and SetDataLamarckian from individual data type interfaces to SetGenotype and SetPhenotype.
+			Repaired the GenericArrayEditor. Population measures can now be plotted in stats.
+
+2.026: Added DiversityTerminator and KnownOptimaTerminator, slightly changed InterfaceTerminator for these
+			and InterfaceStatistics to provide termination message to text window. 
+			Killed redundant method getGenerations() in Population. Population.getAllSolutions now returns a 
+			SolutionSet combining last population with a set of possibly archived solutions.
+			Post processing with HC may now use variable step size mutation.
+
+2.025: FunctionArea may now plot circles easily. The FLensProblemViewer seems to be cured. 
+
+2.024: Cleaned up AbstractGOParams, deactivated parent logging (saving memory)
+
+2.023: Cleaned up the PF strategy
+
+2.022: Some changes to the SimpleProblemWrapper, not of great interest. However, simple problems may now access a plot 
+quite easily.
