Added support for genotype-likelihood input, and a new function readGL() for parsing such data.
Added new dataset sibsGL with genotype-likelihood data for a pair of siblings.
Added a three-state HMM for full siblings, and model selection through findIBD(..., model).
Added support for sample-specific allelic dropout in all main functions.
New function estimateDropout for estimating sample-specific dropout probabilities from the input data.
Improved documentation and expanded README with two new sections.
Corrected a bug in the forward algorithm, affecting fitted HMM parameters and posterior IBD probabilities. The detected IBD segments remain the same in both built-in datasets.
Report and remove bad markers before analysis. These include monomorphic markers, markers with missing annotation or missing genotypes and those with impossible data.
Added problemMarkers() for identifying and inspecting markers with impossible observations.
Improved documentation and README.
Added links to the Marcinelle paper Vigeland et al. (2026) where ibdfindr is described.
