# AlphaSimR 2.0.0

*updated version numbering to follow tidyverse format with a major version indicating backwards compatibility has been broken

# AlphaSimR 1.6.1

*fixed bug in `mergePops` and `[` (subset) methods - they were failing for populations that had a misc slot with a matrix - we now check if a misc slot element is a matrix and rbind them for `mergePops` and subset rows for `[` (assuming the first dimension represents individuals)

# AlphaSimR 1.6.0

*exported `meanEBV` and added `varEBV` to complement `meanP`/`varP` and `meanG`/`varG`

*Changed all parameters of the CATTLE demographic model to exactly match Macleod et al. (2013) - specifically reducing the mutation rate from 2.5e-8 (from human literature) to 1.2e-8 (used in Macleod et al., 2013) and recombination rate from 1e-8 (generic) to 9.26e-9 (used in Macleod et al., 2013). These changes will reduce number of segregating sites to ~240K per chromosome for 100 samples and will run faster.
