• #889: Allow adding annotations to Cfg elements for Grammatical Evolution.

final var cfg2 = Cfg.<String>builder()
    .R("expr", rule -> rule
        .N("num", "annotation 1")
        .N("var", "annotation 2")
        .E(exp -> exp
            .T("(")
            .N("expr").N("op", 4).N("expr")
            .T(")")))
    .R("op", rule -> rule.T("+").T("-").T("*").T("/"))
    .R("var", rule -> rule.T("x").T("y"))
    .R("num", rule -> rule
        .T("0").T("1").T("2").T("3").T("4")
        .T("5").T("6").T("7").T("8").T("9")
    )
    .build();

• #915: Remove usage of java.security.AccessController.
• #921: Remove object == this "optimization" in equals methods.
• #923: Improve parsing performance of CsvSupport.
• #925: INCUBATION: Implement statistical hypothesis tester. The statistical tests for the engine classes has been stabilized and can be written in the following way.

final var observation = new RunnableObservation(
    Sampling.repeat(200_000, samples ->
        samples.add(DoubleGene.of(0, 20).doubleValue())
    ),
    Partition.of(0, 20, 20)
);
new StableRandomExecutor(seed).execute(observation);

assertThatObservation(observation).isUniform();
