Dec 1, 2025December 2025: Delivered a cross-platform documentation stability improvement for Trilinos by making Doxygen output case-insensitive, preventing file-name conflicts on case-insensitive filesystems (e.g., macOS) and ensuring consistent docs across operating systems. Implemented by setting CASE_SENSE_NAMES to NO across all packages; excluded snapshotted packages to coordinate separately. This change reduces doc generation failures and Git conflicts in docs assets and trilinos.github.io deployments.

Sep 1, 2025Month: 2025-09 — Focused on stabilizing Tempus forward sensitivity workflows in Trilinos by fixing a critical constructor declaration issue. Delivered a targeted bug fix for IntegratorForwardSensitivity to ensure proper instantiation and correct forward sensitivity integration, improving reliability and enabling customers to run forward-mode sensitivity analyses with Tempus. No new features shipped this month; the primary value was increased stability and maintainability of the Tempus integration.

Jun 1, 2025June 2025 performance/feature summary for trilinos/Trilinos: Focused migration and optimization around SingletonFiltering. Key feature delivered: migrate SingletonFiltering from Epetra to Tpetra with Kokkos-based optimization (Kokkos Views and parallel_for) to improve portability and scalability on modern hardware. Implemented a runtime option to compare Kokkos Views against the legacy implementation, enabling risk-managed optimization. Expanded test coverage with multiple transforms (Singleton Filtering, SolverMap, Reindex) and restricted scalar testing to non-ordinal types to maintain compatibility with existing workflows. Addressed compiler issues for complex scalar types, cleaned up documentation and example links, and performed targeted bug fixes (Reindex MultiVector) along with an optional local sort of GIDs in GenerateReducedMap to support current tests. All changes captured in commit 40430ece3c976b81ff6943f25e0a5f285d559df0, co-authored by iyamazaki and signed-off by Curtis C. Ober.

Feb 1, 2025February 2025 (2025-02) – Epetra documentation build stabilization for trilinos/Trilinos. Delivered a Doxygen documentation build fix and documentation hygiene improvements to the Epetra docs pipeline. Implemented: (1) corrected include paths used by the Doxygen/CMake integration, (2) added missing tutorial code examples referenced by the docs, (3) removed a no-longer-existent build target that caused spurious failures, (4) temporarily commented out a broken documentation build to prevent cascading failures while a long-term fix is prepared. These changes were committed under 3322509b95d4e67baaf4d51e896c0335799ad5c7 with message 'Epetra: Missing Tutorial Code'.
