MuMIn package news:

Version: 1.7.0 (2012-01-25)
This version adds possibility to model average and re-rank (with another IC) a 
	model selection table without recreating the fitted models. Models from 
	package 'coxme' are now supported. Model selection tables include now extra 
	columns showing differences in attributes of the modelling function call.
model.avg: use 'model.selection' without refitting the models. Fixed a problem 
	with averaging different types of models together (happened when 'df's were 
	available only for some of component models)
dredge: coefficient tables added to the result (attribute "coefTables"). 
	The code has been streamlined.
print.model.selection: now reports random terms also for objects generated by
	'model.sel'
get.models: can handle 'model.selection' objects from 'model.sel'
model.sel: re-ranking 'model.selection' without recreating original models 
	(works only if the IC can be applied to logLik). Output has additional 
	columns showing differences between models (based on call's arguments)
Added generic methods for 'coxme' and 'lmekin' classes (package 'coxme').

Version: 1.6.6 (2012-01-07)
model.avg: fixed error occurring when non-estimable coefficients existed in the 
	component models (problem reported by Annabel Smith)

Version: 1.6.5 (2011-11-28)
pdredge example changed to use SOCK cluster type (portability issue)

Version: 1.6.4 (2011-11-26)
coefTable: replaces 'tTable' (which still exists, but is deprecated), it 
	accepts an argument 'dispersion'. The dispersion parameter can be also 
	passed from 'model.avg'.
pdredge: collects all the warnings and errors which occur during fitting, and 
	stores them. They are printed below the table.
	The function does more thorough checking of the cluster nodes' environment,
	for possible missing variables and functions.
get.models:  "subset" argument can be now a character vector giving model names.
added demos for model selection with models from 'unmarked' package using 
	'dredge' and 'pdredge'

Version: 1.6.3 (2011-11-15)
pget.models: new function, parallel version of 'get.models'.
(p)get.models: important change of the default behaviour: without the 'subset' 
	argument, ALL models are returned. Also the '...' arguments were not used to
	update the returned models - this is corrected now.

Version: 1.6.2 (2011-11-13)
pdredge: new function, a parallel version of dredge (experimental).

Version: 1.6.1 (2011-11-11)
dredge: added generic support for all 'unmarked' models, and fixed some bugs 
	with it.
model.names: new function (previously was internal only)
CAICF: adds to the collection of rarely used information criteria.

Version: 1.6.0 (2011-11-07)
dredge: most important change (although invisible to the user) is in the way the
	model objects are updated. The new function 'makeArgs' is used to generate 
	the updated call. This results in a very flexible interface to the modelling
	functions. The default method updates the 'formula' argument, other methods 
	can be used to deal with more problematic calls (the models from package 
	'unmarked' were a challenge). Apart from the model classes previously
	supported by 'dredge', support for 'unmarkedFitOccu', 'unmarkedFitColExt'
	and several other 'unmarkedFit' objects has been added.
dredge: has new argument 'extra' to add additional statistics into the model 
	selection table.
r.squared: new function to calculate likelihood-ratio based pseudo-R-squared
subset method for 'model.selection' accepts a shorthand notation "has(x)" to 
	select rows where a variable is present.
support for 'survreg' and 'rq' models (packages 'survival' and 'quantreg')

Version: 1.5.2 (2011-10-21)
dredge: fixed a bug with wrong ordering of column names in the returned 
	data.frame (thanks to Staffan Roos for reporting this).

Version: 1.5.1 (2011-10-20)
compatibility with R prior to 2.13.0: added workarounds for missing generic 
	function 'nobs'.

Version: 1.5.0 (2011-10-18)
model.avg: removed the argument "method", the standard errors and confidence 
	intervals are calculated only for coefficients averaged within a subset of 
	models where they are present (method = "NA"). The "full" coefficients are
	also returned, but without std. errors.
plot.model.selection: new function to visualize the model selection table
manuals expanded, examples revised
getAllTerms: should work for most of the classes derived from 'unmarkedFit'
a load of small improvements, polishings and fixes, generally invisible to the 
	user.

Version: 1.4.4 (2011-10-16)
QAIC: no longer uses model deviance, as it gave biased values.
ICOMP, Cp: new information criteria 
model.avg: now performs a smarter check for duplicate models, fixed calculation 
	of importance values

fixed: method="NA" in model.avg, par.avg now accepts NA's in 'weight'

Version: 0.12.0 (2009-03-24)
Change in version number only. Had to make this jump in numbering, as there was
a typo in DESCRIPTION file of an early version, (0.11.2 instead of 0.1.0), and
since then R-forge mechanism seemed to ignore actual newer versions, as they had
lower number.

Version 0.1.1 (2009-03-22)
Modified: dredge: added "fixed" and "m.max" arguments.

Version 0.1.1 (2009-03-17)
Fixed: par.avg: Variance estimate corrected (previous estimate was square root
of variance). Thanks to Mick Wu.
Fixed: dredge: Apparently "expand.grid" cannot handle too many combinations, so
now dredge stops with a more explanatory message

Version 0.1.0
dRedging (0.11.2) moved to R-Forge.
Since model averaging is now the main focus of the package, its name changed
to MuMIn - MUltiModelINference.
