Version 0.21.0

0.21.0

Breaking changes

• Refactor {class}fwdpy11.conditional_models.SimulationStatus as an enum.
  This change makes correct use much easier.
  PR {pr}1161.
  Issue {issue}934.

Fixes

• {class}fwdpy11.conditional_models.ConditionalModelOutput now contains
  fields allowing one to distinguish if the tracked mutation is still present
  in {attr}fwdpy11.DiploidPopulation.mutations and/or {attr}fwdpy11.DiploidPopulation.fixations
  PR {pr}1163.
  Issue {issue}1160.

New features

• {func}fwdpy11.DiploidPopulation.create_from_tskit is now able to restore
  individual metadata, populating {attr}fwdpy11.DiploidPopulation.diploid_metadata
  and {attr}fwdpy11.DiploidPopulation.ancient_sample_metadata.
  PR {pr}1157.
  Issue {issue}1130.

CI changes

• Remove tests using conda environments.
  This removal was a pragmatic decision to speed up CI time.
• Test macOS/x86 using brew instead of conda
• Reduce number of work flows run for PRs into the dev branch.
  Several work flows are only needed when merging into main.
• Reduce number of work flows running upon push to main/dev.
  We now use branch protection, so in theory any changes merging
  have passed their CI requirements.
