This is a heads-up that we'll be sending a new version of lme4 to CRAN
soon. This is not a major revision (the proximal reason for sending a
new version is to address some minor CRAN-compatibility issues).
However, I did *almost* make a "brown paper bag release"
<http://www.catb.org/jargon/html/B/brown-paper-bag-bug.html>, so if
anyone feels like taking the development version for a spin in the next
day or so that would be appreciated. (The new version is due on CRAN by
Nov 9; we have otherwise completed testing on Travis, win-builder,
reverse dependencies, etc ...)
cheers

NEW FEATURES:
? influence measure code from ?car? rolled in (see
??influence.merMod?)
? ?mkReTrm? gets new arguments ?reorder.terms?, ?reorder.vars?
to control arrangement of RE terms and individual effects
with RE terms within model structures
? adding material from the ?RePsychLing? package (on GitHub;
see Bates et al 2015 arXiv:1506.04967) to show orthogonal
variance components.
USER-VISIBLE CHANGES:
? ?as.data.frame.merMod? finds conditional variance
information stored either as ?attr(.,"postVar")? or
?attr(.,"condVar")? (for ?glmmTMB? compatibility)
? change to defaults of ?[g]lmerControl? to print a message
when fits are singular
? new utility ?isSingular()? function for detecting singular
fits; by default a message is printed for singular fits
? ?allFit? function/methods have been moved to the main
package, rather than being included in an auxiliary source
file
? post-fitting convergence checks based on estimated gradient
and Hessian (see ?troubleshooting?) are no longer performed
for (nearly-)singular fits (see ?isSingular?)
