**Dynamic JVM Language Adds Server-Sent Events, JDBC Cache Store, and AST Generation Capabilities**

**Houston, TX – November 7, 2025** – Ortus Solutions announced the release of **BoxLang 1.7.0**, a major update to its modern dynamic language for the JVM that delivers enterprise-grade capabilities for building real-time, horizontally scalable, and AI-driven applications.

This release introduces **native Server-Sent Events (SSE)** for real-time streaming, **JDBC-powered distributed caching** , **Abstract Syntax Tree (AST)** programmatic access, and **bytecode compatibility versioning**—alongside extensive performance optimizations across the runtime.

## Real-Time Streaming with Server-Sent Events

The centerpiece of this release is full **Server-Sent Events (SSE)** integration via a new `SSE()` built-in function and an enhanced **Emitter system**. These additions empower developers to build real-time, event-driven applications such as AI chatbots, live analytics dashboards, progress streams, and notification services.

Version 1.8 will extend this with an upcoming `SSEConsumer()` API, enabling runtime-to-runtime event consumption for distributed systems.

```
// Stream analytics data in real time
SSE(
    callback : ( emitter ) => {
        var startTime = now();
        while ( !emitter.isClosed() && dateDiff( "s", startTime, now() ) < 300 ) {
            emitter.send({
                activeUsers : getActiveUserCount(),
                requestsPerSecond : getCurrentRPS(),
                avgResponseTime : getAvgResponseTime(),
                timestamp : now()
            }, "metrics");
            sleep(5000);
        }
        emitter.close();
    },
    async : true,
    keepAliveInterval : 15000
);
```

The implementation includes **async execution** , **automatic keep-alive** , **client disconnect detection** , **CORS support** , and **automatic chunking** for messages exceeding 32KB—ensuring efficient, resilient streaming at scale.

```
// Stream AI responses token by token
SSE(
    callback : ( emitter ) => {
        var response = callAIService();
        while ( !emitter.isClosed() && response.hasMoreTokens() ) {
            emitter.send( response.getNextToken(), "token" );
        }
        emitter.send({ complete : true }, "done");
    },
    async : true,
    keepAliveInterval : 30000,
    timeout : 300000
);
```

## Enterprise-Ready Distributed Caching

BoxLang 1.7.0 debuts the **JDBC Cache Store** , a robust distributed caching solution that enables shared caches across multiple BoxLang instances using enterprise databases such as **Oracle, MySQL, PostgreSQL, Microsoft SQL Server, Apache Derby, HSQLDB,** and **SQLite**.

```
// boxlang.json
{
  "caches": {
    "distributedCache": {
      "provider": "BoxCache",
      "properties": {
        "objectStore": "JDBCStore",
        "datasource": "myDatasource",
        "table": "boxlang_cache",
        "autoCreate": true,
        "maxObjects": 1000,
        "evictionPolicy": "LRU"
      }
    }
  }
}
```

The JDBC store includes **automatic schema creation** , **database-specific SQL optimization** , **eviction policy support (LRU, LFU)** , and **Base64 object serialization** for complex types. All cache stores now implement `isDistributed()` for ecosystem introspection.

## Advanced Code Analysis with BoxAST()

Developers can now access BoxLang's internal **Abstract Syntax Tree** through the new `BoxAST()` built-in function. This feature supports the creation of **linters** , **formatters** , **migration tools** , and **refactoring utilities**—making it invaluable for static analysis and CFML-to-BoxLang transitions.

```
// Parse BoxLang code
ast = BoxAST( source : "x = 1 + 2; y = x * 3;" );

// Or use the convenient member method
ast = "function hello() { return 'world'; }".toAST();

// Parse from files
ast = BoxAST( filepath : "myScript.bx" );

// Return as JSON for external tools
astJson = BoxAST(
    source : "function hello() { return 'world'; }",
    returnType : "json"
);

// Parse CFML code for migration tools
cfAst = BoxAST(
    source : "<cfset x = 1><cfoutput>#x#</cfoutput>",
    sourceType : "cftemplate"
);
```

`BoxAST()` supports **BoxLang script and template syntax** , as well as **CFML/ColdFusion** code parsing for migration purposes, returning structured, JSON, or text output.

## Bytecode Compatibility Versioning

To enhance module stability and cross-version reliability, BoxLang now implements **bytecode compatibility versioning**, ensuring that compiled artifacts remain consistent and reusable across multiple runtime releases—a major improvement for module authors and enterprise teams maintaining large applications.

## Performance \& Stability Enhancements

Version 1.7.0 delivers substantial runtime performance boosts, including:

* ⚡ **Faster Scheduled Tasks** via optimized concurrent maps
* 🚀 **Improved Static Initializers** for class loading
* 💾 **Optimized ASM Bytecode Generation** eliminating intermediate disk writes
* 🔁 **Cache Store Enhancements** across all providers

Additionally, over **40 bug fixes** improve database interaction, file handling, HTTP services, CFML compatibility, and Windows platform support.

## Open and Professional Ecosystem

BoxLang follows a **professional open-source model** with three editions: **Open Source (Apache 2.0)** , **BoxLang+** , and **BoxLang++** .  

The open-source core remains free, while commercial tiers provide support, advanced modules, and enterprise tooling—licensed fairly based on **usage, not infrastructure**.

New **BoxLang+ exclusive modules** include:

* 🧠 **bx-redis** – High-performance Redis integration
* 📊 **bx-csv** – Advanced CSV processing
* 🔐 **bx-ldap** – LDAP directory services
* 📈 **bx-spreadsheet** – Excel file operations
* 📄 **bx-pdf** – PDF generation

Future roadmap modules include **bx-couchbase** , **bx-mongodb** , and **bx-elasticsearch**.

## Availability \& Resources

BoxLang 1.7.0 is available now via:

* **BoxLang Quick Installers** (Mac, Linux, Windows)
