NIMBLE version 0.9.1 released

[Chris Paciorek]

Hi all,

We've released Version 0.9.1 on CRAN and on our website.  Version 0.9.1 is primarily a bug fix release but also provides some minor improvements in functionality.

Users of NIMBLE in R 4.0 on Windows MUST upgrade to this release for NIMBLE to work.

New features and bug fixes include:

• switched to use of system2() from system() to avoid an issue on Windows in R 4.0;
• modified various adaptive MCMC samplers so the exponent controlling the scale decay of the adaptation is adjustable by user;
• allowed pmin() and pmax() to be used in models;
• improved handling of NA values in the dCRP distribution; and
• improved handling of cases where indexing goes beyond the extent of a variable in expandNodeNames() and related queries of model structure.

Please see the NEWS file in the installed package for more details (https://github.com/nimble-dev/nimble/blob/devel/packages/nimble/inst/NEWS).
