Changes in version 0.3.0 (2026-05-08) Major changes - Introduced use_backward_simulation argument in set_smc_options() to toggle Particle Gibbs with Backward Simulation (PG-BSi) during the rejuvenation step for mixture models. This vastly improves the effective sample size per second for clustering models. Changes in version 0.2.1 (2026-02-04) Bug fixes - Adjusted test tolerance in test-compute_sequentially_partial.R to account for platform-specific numerical differences that caused test failures on r-oldrel-macos and noLD platforms. Changes in version 0.2.0 (2026-02-03) Initial release.
