October 2025 monthly summary for pentaho-platform. Focused on platform stability cleanup by removing deprecated or high-risk components and consolidating dependencies to reduce risk and simplify future upgrades. Key changes include disabling the big-data-legacy core, S3 VFS, and Kafka plugins for debugging/maintenance, and removing the MapReduce library from the Pentaho platform. These changes align with backlog [BACKLOG-45832] and were implemented across PDI and server assemblies. Note that this work may temporarily impact processes relying on these components, but it significantly lowers failure surface and maintenance burden.

June 2025 focused on delivering a standardized API layer for Pentaho Server and laying groundwork for future modular integrations within pentaho-platform. Delivered the Shim API Library, establishing a consistent interface for API interactions and improving compatibility across components.

January 2025 monthly summary: Key feature delivered: HV Karaf Dependency Version Update in pentaho/maven-parent-poms to HV-specific version, aligning dependencies and build configuration. Major bugs fixed: None reported this month. Overall impact and accomplishments: Aligns HV baseline across Maven parent poms, reducing dependency drift and improving build reproducibility, enabling smoother HV deployments. Technologies/skills demonstrated: Maven POM management, dependency versioning, HV/Karaf baseline alignment, backlog traceability (BACKLOG-43212) with commit b2dbfcd6d29a8d4b86883866cd1baa3a854263aa.

November 2024 delivered security hardening, logging modernization, and platform stability improvements across the Pentaho suite, enabling safer deployments and clearer observability with fewer maintenance burdens. Security patches upgraded Karaf to 4.4.6 in all affected repositories (scheduler plugin, Hadoop shims, platform, and big-data plugin), addressing multiple vulnerabilities. The logging stack was modernized by adopting SLF4J 2.0.x and centralizing log4j-slf4j2-impl in the Pentaho parent POM, ensuring consistent logging behavior and easier upgrades across all projects. Reliability fixes addressed excessive DEBUG logging and missing log service, and tests were updated to reflect SLF4J packaging expectations. Runtime dependencies were refreshed (Baouncy Castle 1.78.1) to align with security baselines. These changes collectively improve security, observability, and maintainability, delivering measurable business value with minimal risk.
