﻿skpr v0.40.1 (Release date: 2017-10-20):
================

• Fixed significant bug with parallel design generation that broke automatic detection of the number of cores available.

• Changed non-split-plot D-optimal design search to use modified Fedorov's algorithm with delta function (changed from modified Fedorov's, without delta function). Decreases search time for complex designs or designs with many trials.

• Turned off OPENMP warning for all c++ files.

skpr v0.39.0 (Release date: 2017-10-15):
================

• All the evaluation functions will now respect pre-set contrasts for categorical factors. If a contrast isn't set for a factor, it will use the contrast set in the contrasts argument. 

• Added the ability for the user to specify the number of cores manually by setting options(cores=). Otherwise, gen_design will use all cores available if parallel=TRUE.

• Added the ability for the user to interrupt the design search in gen_design for both single core and multicore searches. When user interrupts parallel search, gen_design will properly stop and close all connections.

• Added calculation of effect power for interaction terms and higher order terms.

• Changed eval_design so that the output always reports parameter power even if all factors are continuous.

• Fixed bug in eval_design_custom_mc which resulted in imported designs overwriting the generated list of contrasts with NULL.

• Changed delta argument to more descriptive "effectsize". Updated documentation and codebase to reflect this change. Effect size now accepts a length-two vector to either explicitly specify the difference in the high and low levels, or to specify GLM-family specific effect sizes. Updated GUI to reflect effectsize change.

• Changed Monte Carlo simulated estimates plot for exponential GLMs to show mean parameter rather than rate.

• Fixed bug when tibble was converted to data frame and didn't convert the character columns to factors. Turned off OPENMP warning in compilation

• Added support for ~.*. operator, allows user to specify full interaction model (no quadratic terms).

• Updated documentation.
