-Had to update the package due to some tests failing on Sparc Solaris. As far as I can tell, the issue seems to be resolved now (see the [[http://cran.r-project.org/web/checks/check_results_metafor.html|CRAN Package Check Results]]). Also, after some extensive testing, I decided to change the default optimizer for ''[[https://wviechtb.github.io/metafor/reference/rma.mv.html|rma.mv()]]'' from ''optim()'' with ''"Nelder-Mead"'' to ''nlminb()''. This is in principle a non-backwards compatible change, which I am not crazy about doing, but really a necessary one. Extensive testing indicated that ''nlminb()'' (and also ''optim()'' with ''"BFGS"'') is typically quicker and more robust than the implementation of the Nelder-Mead algorithm in ''optim()''. Full changelog [[:updates_old#changes_in_version_19-7_2015-05-22|here]].+Had to update the package due to some tests failing on Sparc Solaris.
