Version 3.7.0 (Earth)- Release notes¶

(*) Active Maintenance Period

The present document contains information regarding product enhancements, fixed issues and known issues related to AnswerModules Modules Suite version 3.7.0.

Module Suite Compatibility Matrix¶

(*) Requires hotfix hotFix_ANS_340_010 to be installed

(**) Requires hotfix hotFix_ANS_360_009 to be installed

(***) Requires hotfix hotFix_ANS_370_003 to be installed

SASL Memcache Authentication Support¶

Module Suite 3.7.0 introduces support for SASL memcache authentication. When enabling this feature on OTCS, follow these important steps:

Steps to Enable SASL Memcache Authentication¶

1. Configure the cache to use a single thread client as described above.
2. Enable SASL authentication in your OTCS settings.
3. Save the base configuration to apply the changes.

Module Suite 3.7.0 Breaking Changes¶

Module Suite 3.7.0 it's based on Groovy 4. Groovy 4 builds upon existing features of earlier versions of Groovy. In addition, it incorporates numerous new features and streamlines various legacy aspects of the Groovy codebase.

Important naming/structuring changes¶

Maven coordinate change¶

In Groovy 4.0, the groupId of the maven coordinates for Groovy have changed from org.codehaus.groovy to org.apache.groovy.

Legacy package removal¶

The Java Platform Module System (JPMS) requires that classes in distinct modules have distinct package names (known as the "split packaging requirement"). Groovy has its own "modules" that weren't historically structured according to this requirement.

Groovy 3 provided duplicate versions of numerous classes (in old and new packages) to allow Groovy users to migrate towards the new JPMS compliant package names. See the Groovy 3 release notes for more details. Groovy 4 no longer provides the duplicate legacy classes.

In short, time to stop using groovy.util.XmlSlurper and start using groovy.xml.XmlSlurper. Similarly, you should now be using groovy.xml.XmlParser, groovy.ant.AntBuilder, groovy.test.GroovyTestCase and the other classes mentioned in the prior mentioned Groovy 3 release notes.

New features¶

Switch expressions¶

Groovy has always had a very powerful switch statement, but there are times when a switch expression would be more convenient.

def result = switch(i) {
    case 0 -> 'zero'
    case 1 -> 'one'
    case 2 -> 'two'
    default -> throw new IllegalStateException('unknown number')
}

Sealed types¶

Sealed classes, interfaces and traits restrict which other classes or interfaces may extend or implement them. Groovy supports using a sealed keyword or a @Sealed annotation when writing a sealed type.

sealed interface Tree<T> {}
@Singleton final class Empty implements Tree {
    String toString() { 'Empty' }
}
@Canonical final class Node<T> implements Tree<T> {
    T value
    Tree<T> left, right
}

Records and record-like classes (incubating)¶

Groovy 4 adds support for native records for JDK16+ and also for record-like classes (also known as emulated records) on earlier JDKs.

record Cyclist(String firstName, String lastName) { }

Built-in type checkers¶

From Groovy 4, we bundle some select type checkers within the optional groovy-typecheckers module, to encourage further use of this feature.

@TypeChecked(extensions = 'groovy.typecheckers.RegexChecker')
def whenIs2020Over() {
    def newYearsEve = '2020-12-31'
    def matcher = newYearsEve =~ /(\d{4})-(\d{1,2})-(\d{1,2}/
}

GINQ, a.k.a. Groovy-Integrated Query or GQuery (incubating)¶

GQuery supports querying collections in a SQL-like style.

from p in persons
leftjoin c in cities on p.city.name == c.name
where c.name == 'Shanghai'
select p.name, c.name as cityName

Other improvements¶

• GString performance improvements
• Enhanced Ranges
• Support for decimal fraction literals without a leading zero
• JSR308 improvements (incubating)
• AST transformation priorities

Legacy consolidation¶

• Old parser removal
• Classic bytecode generation removal

JDK requirements¶

Groovy 4.0 requires JDK16+ to build and JDK8 is the minimum version of the JRE that we support. Groovy has been tested on JDK versions 8 through 17.
