Changes in version 1.0.1 (2026-10-22) - Initial release: offline CAPS, single-substitution site-creation dCAPS, conventional two-reaction ARMS and tetra-primer ARMS candidate design. - Evaluate perfect-match primer thermodynamics, sequence compatibility and theoretical complete digests with explicit uncertainty and search limits. - Provide source-linked coordinate and band schematics, within-method preference ranking, reproducible exports and an optional local Shiny interface. - Apply tetra-primer product-size bounds to the control and both diagnostic products; retain separate broad pairwise risk screening. - Include runnable public-API examples and regenerable computational references. - Expand the source-verified enzyme panel to 20 distinct motifs, including MfeI-HF. - Add an offline 550-bp synthetic teaching locus and practical-length workflows for CAPS, dCAPS, conventional ARMS and tetra-primer ARMS. - Provide a version-specific software citation through citation("SNPAssayR"). - Record ICAR-Indian Institute of Rapeseed-Mustard Research (ICAR-IIRMR) as copyright holder while retaining the three authors and designated maintainer.
