August 2025 highlights strong business value through more robust MCMC workflows and improved developer tooling. Delivered Delayed Rejection MCMC integration in MaCh3 with configurability and MCMCBase support, enabling more efficient sampling and easier experimentation. Re-enabled autosave for AMCMC to preserve adaptive covariance, reducing risk during long runs. Implemented stability and backward-compatibility fixes across the MCMC framework, including MR2T2 aliasing and resumption initialization, improving reliability and easing upgrades. Standardized Divergence-aware DMCMC defaults in MaCh3Tutorial to boost robustness and performance in production-like scenarios. Added Python bindings for MR2T2 and DelayedMR2T2 with set_chain_length exposure to streamline scripting and integration. These changes collectively reduce risk in production runs, accelerate experimentation, and improve cross-team collaboration through clearer APIs and docs.

July 2025: Implemented key enhancements to diagnostic plotting workflows across MaCh3 and MaCh3Tutorial, focusing on output organization, multi-file labeling, and CI diagnostics. README and CI-related documentation were updated to reflect new usage patterns. No explicit bug fixes are recorded for this period; the work prioritized feature delivery and documentation to improve reproducibility, visualization clarity, and CI readiness.
