MixSIAR 3.1.10
=========================

## MINOR IMPROVEMENTS

* fixed minor mistakes in manual (new example datasets table)
* scale mix and source tracer data (so can always use same priors regardless of scale of data)
* update compare_models to work with loo 2.0.0

MixSIAR 3.1.9
=========================

Nothing changed, just trying to get new Zenodo DOI (3.1.8 failed)

MixSIAR 3.1.8
=========================

## MINOR IMPROVEMENTS

* updated manual
* new example: alligator diet, model comparison table with LOO/WAIC weights
* new example: mantis shrimp diet, informative priors + combining sources
* new function 'compare_models' to perform model selection based on LOO/WAIC weights, via 'loo' package
* new function 'combine_sources' to aggregate sources a posteriori
* new function 'summary_stat' to print summary of posterior after combining sources
* new function 'plot_intervals' to plot CI of posterior after combining sources

MixSIAR 3.1.7.9001
=========================

## MINOR IMPROVEMENTS

* Removed `attach.jags` call (now directly use `jags.1$BUGSoutput$sims.list`)
* Added epsilon (multiplicative error term) estimates to output (summary stats, posterior plots)

## BUG FIX

* Fixed bug #129 by using `MCMCpack::rdirichlet` instead of `compositions::rDirichlet.rcomp`
* Small changes to pass R CMD check

MixSIAR 3.1.7.9000
=========================

## MINOR IMPROVEMENTS

* Improved continuous effect output plots: 1) added 95% CI shading, 2) plot each level of fixed effect
* Fixed bug with 1FE + 1RE: empty levels Heidelberger diagnostic (#100)
* Fixed bug with 1FE + 1RE: posterior density plots saved over themselves
* Added return value for output_JAGS function: now returns p.both if 1FE + 1RE

* Updated CITATION and manual
