+Cautions
+B estimation is not entirely stable--at least with more than 2 spp and unconstrained Q and R.  
+
+Version 2.66 July 8, 2009 versus 1/21/09 version
+
+fixed x00 init bug in MCInit when x00init<1
+fixed bugs to B estimation and allow fixed B and fixed Z and fixed U
+changed parametric bootstrap to match Stoffer and Wall rec to use e(1:3,) original rather than bootstrapped. 
+added AICc
+added try() in emHessian so it doesn't choke when the Hessian can't be inverted
+add require(mvrnorm) to newData so it can be called alone;
+a couple more init bugs due to R's diag() behavior
+added Hessian.AICb to bootstrapMSSM
+floor added to dim checking of inits so identical() works
+added vectorizemssm and emHessian to KalmanEM file
+fixed bug re loglike not being passed back when x00prior=T; also made the init error-checking more robust
+changed call to Kfilter to be Kfilter(model); fixed dimensions of all outputted params
+bug in the error checking for equalvarcov
+fixed typo in U update
+changed the bootstrap inits; changed the x00inits
+needed to recalculate kf when x00prior=FALSE before returning to user
+fixed LL bug when missing values; fixed U update bug when Q unconstrained; changed iter.record so it dynamically sizes itself; added some whistles to the silent=F output
+added x00prior argument
+fixed Qinit and Rinit to take matrices and vectors
+added equalvarcov.groups
+fixed K calc for AIC
+added debugit to arg list so iter.record isn't always stored; added FailedArgumentCheck function
+replaced T with TRUE throughout; fixed AICi call; changed bootstrapMSSM to take vector for output options
+removed CIs for states in arg list
+changed the AICi routine so it doesn't require nBoot^2 Kfilter calls
+Added AICi; added arguments and error-checking for bootstrapMSSM; added AIC to KalmanEM()
+error was being thrown when equalvarcov set because Q.groups requirement was too picky
+
 Updates in the 5/11/09 vers. (over the 1/26/09 vers) of KalmanEM.R
 * The main KalmanEM() function will output AIC and AICc.
 * Bugs in B estimation were fixed.
