Picocli 3.9.2

The picocli community is pleased to announce picocli 3.9.2.

This release contains bugfixes and enhancements.

Picocli now has a mailing list picocli at googlegroups dot com. Alternatively visit the picocli Google group web interface.

The user manual has improved documentation for internationalization and localization, and the section on Dependency Injection now has a Spring Boot example and link to the Micronaut user manual.

Bugfixes: AutoComplete now uses the specified IFactory correctly for CommandLine; defaulting usageHelp or versionHelp options no longer prevents validation of required options; and usage help for booleans options with arity = "1" now correctly show the option parameter in the synopsis.

Many thanks to the many members of the picocli community who contributed pull requests, bug reports and participated in discussions!

This is the forty-seventh public release.
