December 2025: Delivered targeted QEMU CHERI build improvements in cheribuild. Explicitly included xcheri and cheristd targets and refined path handling, resulting in a cleaner, faster, and more reliable CHERI build process. No major bug fixes reported this month. The changes strengthen CI reproducibility and shorten iteration cycles for CHERI-enabled workflows, delivering business value through more predictable builds and reduced maintenance.

November 2025: Delivered enhanced QEMU build configuration and multi-target support in CTSRD-CHERI/cheribuild, aligning with the Cheri Alliance upstream and expanding target coverage to Arm, Morello, and x86. This improves build reliability, cross-platform testing, and deployment readiness across Cheri-based environments. Key commit: 7522b797776b24cd6b1a07df76d2bd76b6f217cf (qemu: Move std093-qemu to track the Cheri Alliance main branch).

2025-10 monthly summary for CTSRD-CHERI/cheribuild: Implemented performance and compatibility improvements across CHERI, OpenSBI, and build tooling; results in improved CHERI pointer relocation handling, configurable firmware jump addresses for FPGA experimentation, and cleaner install artifacts.

August 2025 monthly summary focusing on CHERI build system and firmware target enhancements. Delivered core Cheri Alliance OpenSBI target support with precise RVY memory address alignment and updated boot/firmware start handling. Implemented Cheri Alliance U-Boot build target, updated QEMU branch, and redirected LLVM builds to a private repo to enable CheriBSD builds. Strengthened cross-compiler support for CHERI ABIs and improved host/build stability by addressing common compiler compatibility issues. Reduced build-time failures and improved path to production-ready CheriBSD environments across multi-target configurations.

July 2025 — CTSRD-CHERI/cheribuild delivered targeted improvements across toolchain selection, debugging support, cross-library build capabilities, and configuration cleanup. These changes enhance build reliability, broaden platform coverage (including morello and riscv64), and enable more efficient performance testing for CHERI-enabled projects.

June 2025 monthly summary focusing on delivering CHERI ISA-aware CheriBSD build and RISC-V QEMU emulation configuration in the cheribuild repository. Highlights include conditional build target selection based on CHERI ISA and ISA-aware QEMU emulation flow. These changes improve reproducibility and enable CHERI-enabled CI targets.

May 2025 monthly summary focused on targeted build-system reliability improvements for the CTSRD-CHERI cheribuild repository. Delivered a precise fix to CheriBSD build logic to honor the riscv_cheri_isa configuration flag by setting TARGET_CPUTYPE based on the ISA variant (V9 or STD). This resolves misalignment between ISA configuration and CPU type selection, reducing build failures and improving cross-variant compatibility across CheriBSD images.

April 2025: Stabilized builds for CHERI- based projects by gating MALLOC_REVOCATION_SHIM behind CHERI_CAPREVOKE to avoid build issues when CAPREVOKE is not enabled. This change improves build reliability across configurations and reduces the risk of misconfiguration.
