55 Commits • 27 Features

Oct 1, 2025

October 2025 monthly summary: Delivery focus centered on stabilizing the platform, expanding AI-driven capabilities, and enabling repeatable release processes across Kestra plugins. Highlights include feature work in the Kestra AI Plugin to improve task execution with system prompts, chat messages, updated model usage, and memory management, plus a fix for the PostgreSQL memory provider default builder. A new SqlDatabaseRetriever was introduced to enable SQL content retrieval via LangChain4j across PostgreSQL, MySQL, and H2, with tests and dependencies. Release automation workflows were added across multiple plugins to standardize and accelerate releases, including versioning, tagging, and optional publishing. Documentation updates and a key alignment of Kestra core versions to exact 1.0.0 across several modules improved build stability and user guidance. Additional advancements included Azure Data Lake upload lease concurrency control, LINE notification broadcast API refactor, and broader dependency stabilization tied to Kestra 1.0.0. Overall impact: faster time-to-release, more predictable builds, stronger data-layer capabilities, and clearer guidance for users and operators.
