Apr 1, 2026April 2026: Focused on security hardening and API compatibility for XML processing in HPCC-Platform. Implemented libxml2 2.15+ compliant updates to the XML processing pipeline, removed deprecated elements and insecure parsing options, and added targeted unit tests to verify behavior. This work reduces vulnerability surface, improves stability, and aligns with downstream XSLT processing expectations. Result: safer, standards-compliant XML handling with preserved functionality and clearer maintainability.

Oct 1, 2025October 2025 performance summary for HPCC-Platform. Delivered two critical bug fixes that improve test reliability and data correctness: WS_smc unit tests are now order-insensitive and DFUQuery responses correctly expose compressed data flags for flat files. These changes reduce flaky test behavior, prevent misinterpretation of compressed data, and provide clearer field semantics for DFUQFieldInfo, enabling safer deployments and easier maintenance.

Jun 1, 2025June 2025: HPCC Platform (hpcc-systems/HPCC-Platform) delivered three targeted improvements to reduce operational noise, improve reliability, and ensure correctness of tooling, with direct business value in faster issue diagnosis and more predictable deployments. Key changes include: (1) Logging Output Management to reduce log chatter and add traceHttp flag, (2) Dali Version Info Retrieval Robustness with pre-fetch connection verification and clearer error messages for network failures, (3) ECL Unused-Files Packagemap Check Accuracy ensuring only active packagemaps are considered for used-files detection in line with documentation. These changes collectively lower maintenance costs, improve observability, and increase system reliability. Key commits: - HPCC-34315: fa895b768d82f1b0e0d375ba1ca4bbfefa52cf0c (Logging Output Management: Reduce costly log chatter) - HPCC-34363: 11e23ac35e56f1e9722001c71765859d9606b308 (Dali Version Info Retrieval Robustness: Improve error when can't connect to get dali version info) - HPCC-34418: be00e9e70716391dd6a3f39347b1c75dc3fee325 (ECL Unused-Files: check-packagemaps should match documentation)

Apr 1, 2025April 2025 performance summary for hpcc-systems/HPCC-Platform: Focused on reducing operational noise while enhancing cost visibility for workloads. Key features delivered include system-wide logging improvements and cost-based search enhancements that directly impact reliability and business decisions. Specifically, System Logging Noise Reduction for InfoCacheReaderThread and ws_cloudService consolidates log messages and adds on-demand data refresh, reducing verbosity and improving responsiveness. ws_cloudService now refreshes on-demand when data is stale, preserves the default stale timeout, and surfaces a warning for deprecated configuration properties, contributing to better observability and fewer unnecessary cache rebuilds. Additionally, WUQuery Cost-Based Filtering Enhancement (Version 2.02) introduces minimum cost filters for compile, execute, and file access costs, with an interface update to 2.02 to support refined, cost-aware searches.
