Changes in version 2025-09-01 Major release. Architecture rebuilt for speed, stability, and cleaner workflows. Recommended upgrade. Highlights - 3–5× faster on typical problems via rewriting core kernels in RcppArmadillo. - Adaptive lambda search that scales to large problems with fewer evaluations. - Element-wise penalty control for both coefficients and network edges. Algorithm & Features - Consistent search strategy in missoNet() and cv.missoNet(). - Fine-grained penalty customization through beta.pen.factor and theta.pen.factor, enabling exclusion of predictors or structured sparsity patterns. - relax.net option for de-biased network estimation: refits the active edge set without L1 penalties to reduce bias in the precision matrix. - Support multiple graphical lasso backends (e.g., glassoFast (default) / glasso) with automatic selection and reliable fallbacks. - Smarter defaults and data-aware initialization tuned to dimensionality, missingness, and conditioning. - Full parallelization for cross-validation and grid evaluation. Performance & Robustness - Vectorized algebra and memory reuse; internal benchmarks show 3–5× speedups - The warm-start strategy has been rewritten to enhance stability. - Tighter line search and stopping in FISTA; fewer oscillations. - Epsilon‑safe numerics; strict finite‑value checks. Visualization & UX - Upgraded S3 plot() for publication-quality output. - Clearer progress and diagnostics (stages, backend, convergence). Documentation - New vignettes: introduction, advanced features, case studies. - Cross-references and examples aligned across missoNet() and cv.missoNet(); arguments and return values documented consistently. Bug Fixes - Fixed Inf propagation in preprocessing. - Fixed cross-package reference linking. - Removed unused external data to reduce package size. - Miscellaneous bugs. Compatibility: Minor API changes; refined defaults. See ?missoNet, ?cv.missoNet. Changes in version 2023-07-18 - More reliable convergence in difficult edge cases; fewer premature stops. - Streamlined initialization with better defaults. - Removed glmnet dependency. - Better diagnostics and messages. Changes in version 2023-05-10 - Final evaluations are now based on warm starts. - Tuned default parameters based on empirical testing across representative datasets. - Dropped C++11 requirement. Changes in version 2022-10-06 - Initial CRAN release.
