BATSS 1.2.1 (2026-09-01)
- Fixes a bug in
batss.glm (reported by Stina Zetterstrom) that
required intervention groups to be listed in alphabetical order
in prob0 for the corresponding allocation probabilities to be
correctly assigned when using RAR.
BATSS 1.2.0 (2026-05-28)
- Improvements to
batss.glm:
interim = NA now specifies a fixed (non-adaptive) design
with a single look at the maximum sample size N- better warnings
- Fixes to minor bugs detected by Claude (Opus 4.6) in version 1.1.1 of
batss.glm, batss.combine, summary.batss, plot.batss and
internal functions, including a fix to eff.trial.control and
fut.trial.control being ignored in trial-level stopping decisions

plot.batss, that now accepts
a new argument, beta
