We're excited to announce the release of BoxLang 1.2, a significant milestone that demonstrates our commitment to delivering both cutting-edge features and exceptional performance. This release represents how much innovation the entire BoxLang team can accomplish in just 2 weeks of focused development, bringing you powerful new capabilities while dramatically improving the runtime efficiency that makes BoxLang a compelling choice for modern applications.
BoxLang 1.2 isn't just another incremental update—it's a performance powerhouse packed with developer-friendly enhancements. We've implemented over 30 targeted optimizations across the runtime, from string operations and file handling to function invocations and memory management. These improvements mean your applications will run faster and more efficiently, often without requiring any changes to your existing code.
Enhanced Java Integration: The new Maven pom.xml support for BoxLang Home opens up seamless integration with the entire Java ecosystem, making it easier than ever to leverage existing Java libraries in your BoxLang applications. You can now add any Java dependencies in your BoxLang Home's pom.xml run mvn install and your runtime will be seeded with all the Java Libraries your application needs!
Advanced Logging Control: Take complete control of your application's logging with new encoder options (text or json) and flexible appender choices between file and console output. Your logs, your way. You can also now chose between a file or console appender in all of your configuration files.
Developer Experience: From nested grouped output support to the new BoxModuleReload() function for testing workflows, we've focused on making your development process smoother and more productive.
This release includes extensive performance optimizations that touch nearly every aspect of the runtime:
Optimized Hot Code Paths: Critical operations like string comparisons, numeric casting, and function invocations have been streamlined
Smarter Caching: From configuration lookups to file path resolution, we've added intelligent caching where it matters most
Reduced Overhead: Eliminated unnecessary operations in frequently-called code, including regex optimizations and stream-to-loop conversions
Memory Efficiency: Improved struct operations, hash encoding, and object creation patterns
We've strengthened BoxLang's compatibility with existing CFML codebases through numerous fixes and enhancements, including better date/time handling, improved query parameter support, and enhanced file operations. Whether you're migrating existing applications or building new ones, BoxLang 1.2 provides a more stable and predictable foundation.
BoxLang 1.2 includes 50+ improvements and bug fixes that enhance stability, performance, and developer experience. From small quality-of-life improvements to significant runtime optimizations, this release delivers value across the board.
The combination of new features, performance enhancements, and rock-solid stability makes BoxLang 1.2 our most compelling release yet. Whether you're building high-performance web applications, integrating with Java ecosystems, or modernizing legacy CFML code, BoxLang 1.2 provides the tools and performance you need to succeed.
