+---
+
+**AI Chat** is a refreshingly simple solution for integrating AI into your applications, built around a clean, 
+serializable `ChatCompletion` DTO that maps directly to the OpenAI Chat API. Unlike complex frameworks with 
+non-portable abstractions and breaking changes, AI Chat embraces the stability and ubiquity of the OpenAI 
+ChatCompletion API itself - the most important API for accessing LLMs. 
+
+The simple `ChatCompletion` DTO works everywhere: store requests in databases, send through message queues, 
+use in client workflows, debug with plain JSON, and unlock all of ServiceStack's DTO-based features automatically.
+
+AI Chat includes a customizable ChatGPT-like UI where you control the API keys, billing, and sanctioned providers 
+your users can access - maintaining fast, local, and private AI access within your organization. 
+The UI supports rich multimodal inputs including images, audio, and file attachments with vision-capable models, 
+features full Markdown rendering with syntax highlighting for popular languages, and provides 200+ curated 
+system prompts for various use cases. 
+All chat history is stored locally in the browser's IndexedDB with import/export capabilities for backup and 
+transfer between browsers.

+
+Modern APIs need to serve different types of clients with distinct authentication requirements.
+**Identity Auth** is designed for interactive user workflows with sessions, roles, and permissions,
+while **API Keys** excel at machine-to-machine communication with simple token-based authentication,
+superior performance, and fine-grained scope-based access control.
+
+Previously, supporting both authentication models required maintaining two separate APIs—one protected
+with `[ValidateIsAuthenticated]` and another with `[ValidateApiKey]`—resulting in duplicate endpoints
+and documentation.
+
+ServiceStack's enhanced API Keys feature now lets you protect the **same APIs and UIs** with both
+authentication models. By adding a user's API Key to the `apikey` claim in their Identity Auth Cookie,
+authenticated users can seamlessly access `[ValidateApiKey]` protected APIs without sending the key explicitly.
+This unified approach eliminates API duplication while maintaining all the benefits of both authentication paradigms.

+Comprehensive **Request Logging & Analytics** is now available for **PostgreSQL**, **SQL Server**, 
+and **MySQL** with `DbRequestLogger` - a drop-in replacement unlocking deep, interactive API analytics 
+previously limited to SQLite.
+
+Get invaluable insights into API usage, performance monitoring, user behavior, troubleshooting, resource planning, 
+and security with visual dashboards that make complex log data instantly understandable.
+
+The analytics are fully interactive, allowing you to drill down from high-level dashboards into individual API 
+endpoints, users, API keys, and IP addresses. Each view provides comprehensive metrics including request volumes, 
+response times, HTTP status distributions, duration histograms, and direct links back to filtered request logs 
+for rapid troubleshooting. Monitor your most-used APIs, identify performance bottlenecks, track user activity patterns, 
+and spot unusual traffic - all from the Admin UI.

+
+We're excited to announce that we've created a drop-in replacement for our much loved SQLite **Background Jobs**
+feature to run in **PostgreSQL**, **SQL Server**, and **MySQL**! The new `DatabaseJobsFeature` maintains the 
+same simple API, data models, and service contracts - making migration straightforward while integrating 
+with your existing database infrastructure.
+
+Add it to your .NET 8+ project with a single command. The implementation leverages each database's strengths - PostgreSQL 
+gets automatic monthly table partitioning, while SQL Server and MySQL use indexed append-only tables for efficient job 
+history management or maintain jobs in a separate database to isolate write-heavy workload from your primary App Database.
+
+It has all the loved features: queue APIs or Commands, schedule recurring tasks with CRON expressions,
+execute jobs serially with named workers, auto-retry failed jobs, and monitor everything in real-time through 
+the Admin UI. 
+
+Whether you need to integrate with existing enterprise infrastructure or leverage advanced RDBMS features - 
+Database Jobs now works with your preferred DB!
