v5.0.0

MixedModels v5.0.0

NEWS file.
Diff since v4.38.0

Version 5.0.0 contains some user-visible changes and many changes in the underlying code.

• Options related to multithreading in the bootstrap have been completely removed.
• Model fitting now uses unconstrained optimization, with a post-fit canonicalization step so that the diagonal elements of the lower Cholesky factor are non-negative. Relatedly, support for constrained optimization has been completely removed and the lowerbd field of OptSummary dropped.
• The default optimizer has changed to use NLopt's implementation of NEWUOA. Further changes to the default optimizer are considered non-breaking.
• The profile function now respects backend and optimizer settings.
• The deprecated hide_progress keyword argument has been removed in favor of the shorter and affirmative progress.
• A fitlog is always kept and stored as a Tables.jl-compatible column table.
• See NEWS.md for more details
