v0.12.1

NIMBLE is a system for building and sharing analysis methods for statistical models, especially for hierarchical models and computationally-intensive methods (such as MCMC and SMC).

Version 0.12.1 follows shortly after 0.12.0 and fixes a bug introduced in conjugacy processing in version 0.11.0 that causes incorrect MCMC sampling only in specific cases. The impacted cases have terms of the form "a[i] + x[i] * beta" (or more simply "x[i] * beta" or "a[i] + beta"), with beta subject to conjugate sampling and either (i) 'x' provided via NIMBLE's constants argument and x[1] == 1 or (ii) 'a' provided via NIMBLE's constants argument and a[1] == 0.
