December 2025 highlights delivering business value through performance, stability, and maintainability improvements across Infinispan-powered repos, with core dependency upgrades for security and compatibility, codebase hygiene, improved test reliability, and enhanced data lifecycle controls for embedding data.

Month: 2025-11. Focused on performance, reliability, and AI capability expansion across four repositories. Key deliveries include (1) Dependency upgrades for performance and compatibility: Infinispan 16.x and Jackson 2.20.1, with removal of outdated dependencies, across langchain4j and related modules; (2) Containerized testing infrastructure: modularized the Infinispan testing container as a separate dependency and improved logging by restoring CountdownLatchLoggingConsumer; and updated docs/examples to reflect the new structure; (3) Containerized testing enablement in Quarkus: upgraded Infinispan to 16.0.2 and switched to testcontainers-infinispan for containerized tests; (4) AI capability expansion: introduced Infinispan as a vector store in Spring AI for efficient vector embeddings storage and retrieval. These changes accelerate runtime performance, stabilize testing, enable scalable CI, and broaden AI storage capabilities.

2025-10 monthly summary for quarkusio/quarkus focused on Infinispan client modernization and performance upgrades. Upgraded the Infinispan client to 16.0.1, adopted a new cache codec, and adjusted schema registration to maintain compatibility with the latest Infinispan features. Implemented a worker event loop group injection to improve concurrency and throughput. These changes enhance feature parity, readiness for new capabilities, and reduce integration risk for future releases.

September 2025 monthly summary for quarkusio/quarkus focused on delivering feature work around Infinispan client-side transactions. Implemented client-side transaction configuration and NON_XA mode support for transactional caches (e.g., bookstx), including updates to the Infinispan client producer, runtime configuration, and integration tests. No major bugs fixed this month; primarily feature enablement, validation, and groundwork for future improvements. Overall impact includes greater flexibility for transactional caching and improved client-side control over transaction semantics.

Month 2025-08: Delivered a critical dependency upgrade for quarkusio/quarkus by upgrading Infinispan to 15.0.19.Final. No application code changes were required; the update brings bug fixes, security patches, and new features inherited from the updated library, improving stability, compatibility, and maintainability. This work aligns with our release cadence and reduces operational risk in production deployments.

July 2025 monthly summary focusing on key accomplishments, delivered features, and reliability improvements across Infinispan, Protostream, and Thingsboard LangChain4j. This period emphasized business value through configurable caching, robust error handling, flexible schema management, and metadata-driven data retrieval, with strong test coverage and documentation to enable adoption and reduce support overhead.

June 2025: Delivered a focused set of maintenance, query, and REST improvements for infinispan/infinispan that enhance stability, data accuracy, and operational efficiency. Key outcomes include dependency/version upgrades for release readiness, significant HotRod query enhancements with nested lists and vector search metadata support, and new REST capabilities for bulk cache management, complemented by targeted bug fixes to improve data exposure and local-server stability. These efforts reduce risk, improve data operations, and strengthen testing/documentation practices across the project.

May 2025 — quarkusio/quarkus: Upgraded Infinispan to 15.0.15.Final to capture upstream bug fixes and improvements. The change was implemented via commit 89007e78ec0aef1f4a534efb2f7eb81add36a33a and maintains compatibility with the existing codebase. This upgrade reduces potential cache-related issues and contributes to runtime stability and performance across production workloads.

April 2025 monthly summary: Delivered key feature enhancements for Infinispan, improved server extension configurability, and completed a critical dependency upgrade to strengthen stability and maintainability across repositories. The work emphasizes business value through better runtime correctness, easier test setup, and up-to-date dependencies that reflect latest bug fixes and improvements.

March 2025 monthly summary for the infinispan/infinispan repo focusing on delivering observable business value through reliable cluster management improvements, security hardening, and correctness fixes. Key work included a new REST API endpoint for per-cluster-member details, a robust root JSON.TOGGLE fix with regression tests, and a CSP header URL handling fix that respects default ports and handles malformed URLs. All changes shipped with tests, documentation updates, and client-facing API support to reduce risk and improve operability in production clusters.

February 2025: Delivered two major JSON‑focused feature sets in infinispan/infinispan, expanding in‑cluster JSON processing and manipulation with improved reliability and documentation. Key outcomes include unified length queries and enhanced JSON data manipulation commands, along with fixes to top-level array handling and legacy path processing. These changes enable richer workloads directly in the data grid, reducing client‑side processing and accelerating time‑to‑value for JSON‑based use cases. Demonstrated capabilities include command registrations, core logic improvements, comprehensive tests, and updated docs.

January 2025 monthly summary for the infinispan/infinispan repository. Delivered targeted updates to align footprint disk usage validation with PT6 Console changes, ensuring tests reflect updated server resource usage and reducing risk of false negatives. Maintained robust integration testing in the face of UI/server updates; quickly updated test constants and validated metrics to support stable releases.

December 2024 performance summary for infinispan/infinispan. Focused on delivering a major platform upgrade and strengthening metrics stability to improve compatibility, observability, and cloud-native readiness. Key work included upgrading Quarkus to 3.15.2 with related stack updates, GraalVM native image tweaks, and Prometheus metric format adjustments, as well as implementing robust handling for negative metric values with dedicated tests.

November 2024 performance summary: Delivered two high-impact updates across repository surfaces with minimal code changes where possible. In infinispan/protostream, replaced the README branding with a new legal logo, added the asset, and removed the old logo to ensure branding aligns with legal requirements. In infinispan/infinispan, upgraded the Console dependency to 15.1.4.Final to align with the latest UI/UX platform, with no code changes required. No major bugs fixed this period; the focus was on branding governance and dependency hygiene that reduce risk and prepare for forthcoming features. Overall, these efforts improve brand integrity, security/compliance posture, and system readiness for UI improvements.

October 2024 monthly summary for infinispan/infinispan: Delivered a documentation-focused feature enhancement to improve version visibility and maintenance. Updated the Version Badge in README to point to the Sonatype Versions page, offering a comprehensive view of all available versions rather than linking directly to a single Maven Central artifact. This aligns with best practices for release visibility and reduces dependency confusion for users and contributors.

September 2024 — Infinispan: Delivered container CLI connectivity documentation for BrandName servers. Documented prerequisites and step-by-step instructions to connect to BrandName servers running in a container, enhancing containerized deployment workflows and developer onboarding. This work is backed by commit ca4157d5ad453b48cf7f385098dfd8851d63e98f and closes #13269. No major bugs fixed this month; focus was on documentation and guidance to accelerate adoption and reduce support overhead.
